15. D. A proxy server is used to forward requests on behalf of other clients. The proxy is configured with an external IP to access the Internet. Answer A is incorrect because a gateway is used to route TCP/IP traffic. Answer B is incorrect because a DHCP server is used to automatically assign IP addresses to devices on a network. Answer C is incorrect because a firewall is used to protect an internal LAN from external Internet access. For more information, see the "Configuring and Verifying Network Connectivity" section.

1. You are installing Windows NT on a new Web server. The network is using private IP addressing internally, but has a set of ten Class B IP addresses issued by the company's Internet service provider to use for any external servers. What steps should you take to install the server and properly configure the network settings? $$ The first step is in the installation is to examine the documentation and any readme files to ensure hardware compatibility and any issues related to installing a Web server. Next, you should start the server with the OS install boot disk or CD-ROM. The disk partitions should now be configured and formatted with the NTFS file system, so that enhanced NT security can be used. A separate partition should be made for the Windows NT system files, and another for the Web server files. If external users are accessing this Web site from the Internet, you do not want to take the chance of them possibly being able to access the system files. Now you can install the operating system to the system partition that was created in the previous step. When the installation is finished, you need to restart the server. After the server reboots, you need to enter some configuration parameters such as the license key, language settings, and domain/ workgroup configuration. Because this server will be used to serve Web pages to external users, it should be configured as a stand-alone server without any domain functions. Now you need to configure the network settings. Use the Class B IP addresses issued by your ISP. Because this is a Web server being accessed by external users, it will not be able to use an internal private IP address. Verify the network settings and connectivity by checking the values displayed from the ipconfig command. Try to ping another server to ensure connectivity. Finally, when the base OS installation is completed, apply the latest service packs and patches to bring the OS system files and related programs up to date.

one in the computer room, and one in a safe in your office. C. Keep one copy on-site, and one copy at an off-site location. D. Keep both copies in a locked safe on-site.

4. C. Never keep just one hard copy of the disaster recovery plan, because it could get lost or damaged if kept on-site. Also, having only electronic copies is useless if you cannot get to your systems. Answer A is incorrect because you would potentially lose these copies if a disaster occurred. Answer B is incorrect for the same reason as A. Keeping them in a safe on-site is not necessarily any safer. Answer D is also incorrect because keeping both copies on-site is a bad idea. If a disaster strikes, even if they are in a safe, there is no guarantee that the safe won't be damaged. For more information, see the "The disaster recovery document" section.

All employees should learn how to issue purchase orders so that they can order the new equipment on their own. D. It is only necessary for the people in the purchasing department to issue purchase orders.

A. Every I.S. team member responsible for the DRP should be able to issue a purchase order. Answer B is incorrect, because unfortunately it will not minimize the effects of a disaster. Answer C is incorrect, because you do not want unauthorized employees issuing purchase orders during a non-disaster situation. Answer D is incorrect, because during a disaster, things need to happen quickly, so you will want at least one person from each department to be able to issue a purchase order. For more information, see the "The disaster recovery document " section.

12. At various times of the day, users are complaining that a particular file server is slow. What should the technician examine first? A. Server event logs B. Network analyzer traces C. MIB database D. Performance monitor counters

A. Examine the event logs to see if any other server events are happening at these times. Answer B is incorrect because you should examine the server first before checking external items such as the network. Answer C is incorrect because examining the SNMP MIB database will not immediately reveal any helpful information, since the data must be processed by a network management system. Answer D is incorrect because the performance has already been recognized as an issue, and examining the performance monitor will not aid in troubleshooting the problem. For more information, see the "Event Logs" section.

14. Upon checking your performance monitor logs, you notice that the hard page faults are consistently high. What should you do? A. Install more RAM. B. Upgrade the disk subsystem. C. Offload some processes to other servers. D. Ignore this, because it really does not mean anything.

A. Excessive page faults indicate that the system needs more RAM. Answers B, C, and D are incorrect because the issue revolves around the hard page faults, and the only real solution is to upgrade the memory. Offloading processes may or may not do anything in this situation. It may only be a certain application that is taxing the memory. For more information, see the "Storage" section.

3. If you are setting up your network analyzer to only monitor TCP/IP on your network, what component will you need to implement? A. Filtering B. SNMP trap C. Sniffer D. MAC address

A. Filtering enables you to specify only certain criteria to search for. Answer B is incorrect because an SNMP trap is not able to monitor network data. Answer C is incorrect because although you may use a network sniffer or analyzer, you would still need to configure a filter for TCP/IP, so that you would not receive information on other protocols. Answer D is incorrect because a MAC address is the network address of each device, and would still include all protocols. For more information, see the "Network Analyzers" section.

28. To test name resolution, what command should an administrator use? A. dig B. ifconfig C. ping D. mount

A. In a Linux system, the dig command can also be used to test name resolution. The ifconfig command is used to display IP configuration settings. The ping command is used to test for connectivity between devices. The mount command is used to mount a hard drive in the system.

Page/sec, Avg. Disk Queue Length, Network utilization, Pool non-paged bytes

A. Include the CPU utilization counter, page/sec counter, Avg. disk queue length counter, network utilization counter. Depending on the operating system you are using, these counters may have slightly different names. However, they will be similar in name and in intent. All other answers are incorrect because they are more geared for measuring performance as opposed to trying to create a baseline. For more information, see the "Creating A Baseline" section.

17. What is the difference between incremental and differential backups? A. Incremental backups take less time to perform than differential backups. B. Differential backups reset the archive bit while incremental backups do not. C. Differential backups require more backups to be restored than incremental backups. D. Both backups are the same. They are named differently because they are proprietary.

A. Incremental backups are faster to perform than differential backups. Incremental backups reset the archive bit while the differential backups do not. Differential backups require less backups to be restored than incremental backups. Because of this, restoration is faster using differential backups than incremental backups. Both backups are not the same, and both are not proprietary.

8. The ability of multiple processes to access a certain section of RAM is called what? A. Memory interleaving B. Caching C. Static RAM D. Dynamic RAM

A. Interleaving increases server performance because multiple processes can access the same parts of RAM. Answer B is incorrect because caching is a way of speeding up RAM access by storing the most recently used instructions. Answer C is incorrect because static RAM is a type of memory that does not need to be constantly refreshed. Answer D is incorrect because dynamic RAM is a type of memory that needs to be constantly refreshed. For more information, see the "DRAM" section.9. A technician receives some additional RAM for a memory upgrade to a server. The technician notices that the new RAM has 184 pins, while the current RAM has only 168 pins, and the new RAM won't fit into the memory expansion slot. What is the cause of the discrepancy? A. The RAM received was 256MB. B. The RAM received was a SIMM module. C. The RAM received was an EDO DIMM module. D. The RAM received was a Rambus RIMM module. $$ D. It is imperative that memory upgrades be verified with current system specifications, as there are many different types of RAM. Answer A is incorrect because the size of the RAM module is dependent on the number of pins. Answer B is incorrect because a SIMM module uses 30 or 72 pins. Answer C is incorrect because a DIMM module is 168 pins, and would have installed correctly. For more information, see the "Installing memory" section.

40. When moving a rack mount server, what is the most important thing to do? A. Remove all components from the rack before transport. B. Push as hard as you can to move the rack to the destination faster. C. Send an email informing others your plan to move the rack. D. Ensure the path is extra slippery to help move the rack.

A. It is important to remove all component from a rack before transport because a rack will all the components attached is extremely heavy and a hazard for crushing. Pushing as hard as possible will increase the likelihood of tipping the server rack. Sending an email informing others doesn't prevent the danger of moving the heavy rack. The path should be checked for potential hazards and not checked to ensure the path is extra slippery.

1. A technician has installed a new network card in a server. Other peripherals on the server include a SCSI tape drive, an on-board sound card, and an AGP video card. When the server is booted, it reports an IRQ conflict with the network card that disables it. What is the most likely cause of the problem? A. Sound card B. Video card C. Tape drive D. System BIOS

A. It is most likely the sound card that is causing the conflict. Answer B is incorrect because the video is running on an AGP slot without conflicting resources. Answer C is incorrect because the tape is using SCSI bus resources. Answer D is incorrect because nothing should conflict with the system BIOS. For more information, see the "Interrupt request lines" section.

7. Why are key locks not the best choice for physical security for the computer room door? A. Key locks get lost, and they can be duplicated. B. Key locks get lost, and they cannot be duplicated. C. Keys regularly break, and they are lent out. D. Key locks are affected by power outages.

18. An application crashed on the server. What should the administrator do first to solve the problem? A. Look through the event logs. B. Restart the application. C. Use a search engine to investigate the cause. D. Escalate the problem.

A. Looking through the event logs will help determine the cause of the application crashing. Restarting the application will not determine the cause of the crash. Using a search engine will not help narrow the cause of the crash. Escalating the problem is not practical as not enough information has been gathered about the problem.

14. A customer complains that there is a light flashing on the NIC card on the back of the server. What could be the cause of the problem? A. Nothing, the light is indicating network activity. B. The NIC card is malfunctioning. C. The NIC card is running at full duplex. D. The NIC card is running at 100MB.

A. Most NIC cards have a light that indicates network activity. It does not indicate an error condition. Answer B is incorrect because there is no error light on the network card. Answer C is incorrect because a duplex light would not flash, it would stay solid. Answer D is incorrect because the speed indicator light would not flash, it would stay solid. For more information see the "Network card lights" section.

15. When examining performance monitor logs, a technician notices a large CPU usage spike everyday at 3 a.m. What could be the source of the problem? A. Backups are scheduled at that time. B. Someone is logging in remotely overnight. C. The SNMP threshold is misconfigured. D. The CPU has malfunctioned.

A. Most off-hours usage spikes are caused by backup operations. This is normal. Answer B is incorrect because a remote user would not cause a big increase in CPU usage. Answer C is incorrect because the setting of the threshold would not cause the CPU spike, it can only measure and detect it. Answer D is incorrect because a CPU malfunction would result in inconsistent behavior. For more information, see the "Identifying Bottlenecks" section.

2. The initial boot drive on an older SCSI bus should have what device ID? A. 0 B. 1 C. 15 D. 7

A. Older SCSI systems will not boot unless the drive is set to ID 0. Newer SCSI technology has eliminated this condition. For more information, see the"Device IDs" section.

For more information, see the "Verifying Power Sources and UPS Installation" section.

23. Which RAID array is the least fault tolerant? A. RAID 0. B. RAID 1. C. RAID 0+1. D. RAID 5.

A. RAID 0 has no fault tolerance at all. Therefore, it is the least fault tolerant.

18. Disk striping with parity contained in a separate drive is an example of what level of RAID array? A. RAID 3 B. RAID 1 C. RAID 5 D. RAID 0

A. RAID 3 uses a disk drive for parity. In RAID 5, parity data is striped across all drives. Answer B is incorrect because RAID 1 defines disk mirroring. Answer C is incorrect because RAID defines data striping with a distributed parity system. Answer D is incorrect because RAID 0 defines disk striping only with no parity. For more information, see the "RAID Levels" section.

3. A new server has just been installed. The server has built-in SCSI SCA connectors, and it has with four 18GB hard drives with 40-pin connectors. Has all the proper equipment been ordered for this server? A. No, SCA requires 80-pin hard drives. B. Yes, all the proper equipment is present. C. No, an adapter cable will be needed. D. No, the hard drives will need termination.

A. SCA adapters require 80-connector drives. Answer C is incorrect because you adapt a regular hard drive to an SCA interface. Answer D is incorrect because the built-in SCSI backplane takes care of termination issues. For more information, see the "SCA adapters" section.

2. A server has one 40GB hard drive, two 50GB hard drive and two 60GB hard drive. The administrator wants to configure all 5 drives in a RAID 5 array. How much usable disk space will this array have? A. 160 GB B. 180 GB C. 200 GB D. 240 GB

A. Since the smallest hard drive is 40GB, that is the maximum size available on each hard drive. With 5 hard drives, n = 5 and the total capacity of the RAID 5 array is 200GB. Using the formula 1 - 1/n yields 0.8, and 200GB x 0.8 = 160GB.

89. A server cannot boot into the operating system. Which diagnostic tool is best suited for this issue? A. POST messages. B. System logs. C. Debug logs. D. Self-sealing stem bolts.

A. Since the system cannot boot into the OS, an administrator needs to rely on the POST message. System logs and debug logs are only available if the OS can be loaded.

4. A SCSI host adapter has been removed and upgraded with an Ultra2 SCSI host adapter. When the system is booted, the system does not see the SCSI bus. What is the most likely cause of the problem? A. The BIOS needs to be updated with a newer version. B. The host adapter ID was not set to 7. C. The SCSI bus was not terminated properly. D. The host adapter is conflicting with another device.

A. The BIOS needs to be updated to recognize the new SCSI device. Answer B is incorrect because the host adapter does not have to be ID 7, although it is preferred. Answer C is incorrect because the termination is not the most likely failure, although it is possible. Answer D is incorrect because the device would have been recognized, but would not have worked properly. For more information, see the "Host adapters" section.

15. An ATAPI CD-ROM has been added to an IDE/ATA system, which is currently configured with one 9GB drive on the primary IDE controller. The CD-ROM is installed on the secondary IDE controller. When the system is started, the CD-ROM is not functional. What is the most likely cause of the problem? A. A CD-ROM driver has not been loaded. B. The CD-ROM should have been installed as a slave on the primary IDE controller. C. The CD-ROM should have been installed as a master on the primary IDE controller. D. The CD-ROM should be configured as a cable-select slave on the secondary IDE controller.

A. The CD-ROM still needs an ATAPI driver to run. Answers B and C are incorrect, because it is best to keep the slower CD-ROM on its own channel separate from the hard drives. Answer D is incorrect because the CD-ROM drive is the only device on that controller and, therefore, does not require cable select. For more information, see the "IDE/ATA standards" section.

13. Which service describes leasing addresses to host computers? A. DHCP B. DNS C. VTP D. SNMP

A. The Dynamic Host Configuration Protocol is responsible for leasing out addresses to host computers. Domain Name Service is responsible for translating domain names to IP addresses. Virtual Trunking Protocol is responsible for propagating VLAN information to other switches in the network. Simple Network Management Protocol is used to simplified management of the network by allowing for automated monitoring of network devices.

11. A. The Internet uses the TCP/IP protocol. Answer B is incorrect because IPX is the Novell NetWare standard protocol. Answer C is incorrect because NTFS is a type of file system used by Windows NT. Answer D is incorrect because NetBIOS is a non-routable protocol used by simple local area networks. For more information, see the "Configuring and Verifying Network Connectivity" section.

A. The Internet uses the TCP/IP protocol. Answer B is incorrect because IPX is the Novell NetWare standard protocol. Answer C is incorrect because NTFS is a type of file system used by Windows NT.

16. A technician has upgraded a server with an empty CPU socket with a second CPU for multiprocessing. The customer complains that there has been no difference in server performance. What might cause this? A. The O/S does not support multiprocessing. B. The new CPU is not fully inserted into the ZIF socket. C. The BIOS needs to be upgraded. D. The CPU is a different brand name than the original.

A. The OS of a server must support multiprocessing for the new processor to provide any benefit. Answer B is incorrect because the second CPU would not be recognized if it were not fully inserted into its slot. Answer C is incorrect because there is no need to upgrade the BIOS in this case. Answer D is incorrect because the CPU manufacturer would not be relevant in this case. For more information, see the "Central Processing Unit" section.

6. You come in one morning to find a system error message on the server terminal. The message is from the backup software, and states that the tape backup job failed because of a hardware error caused by a SCSI Bus Timeout. What might cause this timeout problem? A. The SCSI controller is too fast for the tape backup hardware. B. The SCSI controller is too slow for the tape backup hardware. C. A bad tape. D. Power surges.

A. The SCSI controller is most likely too fast for the tape backup hardware to handle, and thus generates an error. Answer C is incorrect because the tape backup software should generate an error message that is different from that of a SCSI bus timeout error. Most tape backup packages can determine that the tapes are bad, and will generate an error accordingly. Answer D is incorrect because your UPS should protect your hardware from power surges. However, if you are not using a UPS, the power surges will most likely cause the hardware to fail completely, and act erratically. For more information, see the "Improving backup performance" section.

8. A server has recently had its UPS upgraded to a 1200 VA rated UPS. During a recent power outage, the server ran for twenty minutes before the UPS battery ran out.

Which termination method uses resistors for short, low-speed single ended cables? A. Active termination B. Passive termnination C. Congruant termination D. Static termination$$ B. The passive termination method uses resistors for short, low-speed single ended cables. Active termination adds voltage regulators to resistors for more reliable termination. There is no such things as congruant termination or static termination.

A customer is contemplating creating a two-node cluster with a SCSI shared storage configuration to provide quick fault recovery. For which of the following failures will this cluster provide quick fault recover? A. One server in the cluster loses all power. B. The computer room loses all power for an hour or more. C. The shared SCSI storage system for the cluster loses all power. D. The shared SCSI storage system for the cluster loses two disk drives.

Answer: A A cluster is used for failover protection. If one node fails another node in the cluster takes its place. Note: The cluster service can detect a hardware or a software failure (for example that one server stops due to a power loss) and quickly assign the application or service responsibility to another node in the cluster. This process is called failover. Reference: MCSE Training kit (70-223) Microsoft Windows 2000 Advanced Clustering Services, Overview of Microsoft Cluster Service, page 6. Incorrect answers If the computer room loses power both the nodes in the cluster would be shut down. If the shared SCSI storage system fails both nodes in the cluster would be unable to operate.

A technician is concerned about how natural disasters would affect their existing disaster recovery plan. Which of the following disaster recovery plan modifications should be implemented to address this situation? A. Use a remote hotsite. B. Use a local media safe. C. Stock adequate hardware. D. Backup to another local server for redundancy.

Answer: A A remote hot site would not be affected by a natural disaster at the main location. Incorrect answers Local facilities, like a local media safe or backing up to a local server, would give protection from a natural disaster. Stacking up hardware would not be of much help addressing the problem of a natural disaster.

What should be the first consideration when identifying potential server bottlenecks? A. The role of the server. B. Amount of installed RAM. C. Number of installed processors. D. Quantity of installed network adapters.

Answer: A Different server roles (file server, database server, mail server, domain controller, DNS server, etc) have different bottle necks. The role of the server is first thing to consider when identifying potential bottlenecks.

While auditing a client site, the technician notices that the SNMP monitor has a high volume of messages from the servers indicating that each server has reached 5% network utilization. The alerts were configured by the previous administrator. Which of the following actions should be taken? A. Raise the SNMP network utilization threshold. B. Call in a network cabling expert to resolve the errors. C. Subnet the network to decrease the size of the collision domain. D. Set a filter on the SNMP monitor to stop displaying the network utilization messages.

Answer: A Every time the network utilization has reach 5% a network alert is generated. The alert threshold should be raised. Too many alerts are generated with such a low threshold.

A new hardware RAID controller has been installed but is not recognized by the server BIOS. Which of the following could be done to solve the problem? I. Update the system firmware. II. Update the RAID controller firmware. III. Make the IRQ available. IV. Install the Network OS driver. A. I and II only. B. III and IV only. C. I, II, and III only. D. I, II, III, and IV.

Answer: A Explanation: I. A BIOS upgrade might enable the BIOS to detect the RAID controller. II. Updating RAID controller firmware could also enable the BIOS to detect the RAID controller.. III. An IRQ conflict would not prevent the system from detecting the device. IV. The BIOS does not use Network OS drivers.

A technician with six 9-GB drives available needs to create a fault-tolerant array with a capacity of at least 28 GB. Which of the following RAID options will best fulfill these requirements? I. RAID 0 II. RAID 1 III. RAID 5 IV. RAID 0/1 A. III only. B. III and IV only. C. I, II, and IV only. D. II, II, and IV only.

Answer: A Explanation: I. RAID 0, disk striping, is not fault tolerant. II. RAID 1, disk mirroring, use only two disks. III. RAID 5, disk striping with parity, uses one disk for parity. In this scenario it would leave 8 disks for data. 56GB would be used for data. IV. RAID 0/1 combines disk striping and disk mirroring. In this scenario each stripe in the mirror would consists of three 9-GB drivers. Only 27GB of data could be stored in the mirror.

On a Microsoft Windows 2000 server named TestKing, the DHCP service has been installed and a scope created on a server, but the clients are not getting assigned IP addresses. Which of the following is most likely the problem? A. The scope was not activated. B. Lease expiration has not been set. C. No MAC address is assigned in the scope. D. The DHCP service does not have a reservation configured.

Answer: A Explanation: A DCHP scope must be activated. Incorrect Answers B: Lease expiration has a default value. Lease expiration must only be set if you want to configure a nondefault value. C: DHCP dos not use MAC addresses. DHCP leases logical addresses, IP addresses, not physical MAC addresses. D: The DHCP server itself cannot have a reservation configured. The DHCP server should have static IP configuration.

All of the following combinations will result in a valid network connection EXCEPT? A. Server to MDI port with straight cable. B. Server to MDI-X port with straight cable. C. Server to workstation with crossover cable. D. MDI hub port to MDI hub port with crossover cable.

MDI port connected to another MDI port or MDI-X port connected to another MDI-X port: use crossover cable. 2. MDI-X port connected to MDI port: use a straight-through connecting cable. Note 2: Network adapters are wired MDI. Incorrect Answers B: MDI connected MDX requires straight cable (Rule 2). C: MDI to MDI: use crossover cable (Rule 1). D: MDI to MDI: use crossover cable (Rule 1).

A customer requires a server that will use the maximum amount of storage space possible while obtaining the greatest performance. Fault tolerance is not an issue for this installation. Which of the following is the best RAID solution for the server? A. Ultra2 SCSI using RAID 0. B. Ultra2 SCSI using RAID 1. C. Ultra2 SCSI using RAID 0/1. D. Wide Ultra2 SCSI using RAID 5.

Answer: A Explanation: RAID 0, disk striping gives highest performance and as 100% disk utilization as long as the disks are of equal size. It does not provide fault tolerance, but that is not required either. Incorrect Answers B: RAID 1, disk mirror, is not so fast since data need to be written twice. Furthermore, disk utilization is only 50%, C: RAID 0-1, is a combination of disk striping and disk mirroring. Each mirror disk is striped. Still, data need to be written twice and disk utilization is only 50%, D: RAID 5 use one disk as parity and has there lower speed and lower disk utilization compared to RAID 0.

Disaster recovery plans should be prepared at what stage of a server installation? A. Before deployment B. During the annual budge period C. After the server is successfully installed and configured D. Immediately upon symptoms of problems developing with the backup system.

Answer: A Making a disaster recovery plan before deployment seems prudent. You should have a disaster recovery plan in place before the server installation as part of your initial request for server hardware must take into account any extra devices to implement the plan like extra tape drives, disk controllers etc.

Which of the two following options would require an update of a disaster recover plan? I. Adding new hardware. II. A move to a new location. III. Replacing failed hardware. IV. Adding workstations to the network. A. I and II. B. I and III C. II and IV D. III and IV

Answer: A New hardware (I.) and a move to a new location (II.) would force use to make changes in the disaster recovery plan.- Incorrect Answers III: Replacing failed hardware would not change the disaster recovery plan as we still would use the same type of hardware. IV: Adding more workstations to the network would not change the disaster recovery plan. The vital information is stored on the servers, not on the workstations.

When files on the SYS: volume of a new server were configured, an error is made and the server will no longer boot. Which software is required to recover from the failure and continue configuration? A. NetWare CDROM B. Unix Boot/Root diskette(s) C. OS/2 startup disk and Installation disk. D. ERD and/or installation disks with CDROM

Answer: A Novell NetWare servers us a SYS volume. NetWare software is needed to solve the problem at hand. UNIX, OS/2 or Windows does not use SYS volumes. ERD is only used by Windows systems.

Answer: A Printer pooling must use printers connected to a single server. The print devices must use the same print driver. Incorrect answers The print devices cannot have the same IP address. The print devices are often of the same make and model, but it is not a requirement. The must use the same print driver however.

Which of the following would NOT provide redundancy for a server in the event of failure? A. RAID 0 B. RAID 1 C. Disk duplexing D. Network adapter teaming

Answer: A RAID 0, disk striping, improves disk performance but does not provide redundancy.

Which RAID level best provides protection when either two disks fail simultaneously, or when a second disk fails during the reconstruction from the first disk failure? A. RAID 0/1 B. RAID 1 C. RAID 3 D. RAID 5

Answer: A RAID 0/1 is combination of RAID 0 (disk striping) and RAID 1 (disk mirroring). Each mirror consists of a striped volume of disks. It could handle failure of two disks.

A technician has created an array composed of four 9-GB hard drives. Two weeks later, the server is working fine; however, the customer calls to complain that the system only recognizes 27 GB of disk space. What would best explain the situation? A. The customer is running RAID 5. B. One of the hard drives has failed. C. One of the logical drives has failed. D. The customer is running RAID 5 with a hot spare.

Answer: A RAID-5 uses one disk for parity. In a four-disk RAID-5 configuration only three disks would be available for/ During initial installation of a Network OS on a server, the technician configures OEM SCSI and NIC drivers. After completing the installation, the latest Network OS patch is applied. During the installation of the patch, the technician is prompted to overwrite newer files several times. He does as prompted. When rebooting, the system halts. Which of the following could have prevented this problem? I. Reinstalling the SCSI and NIC drivers after the patch II. Not overwriting newer files III. Replacing all overwritten files before rebooting IV. Upgrading OEM drivers from the Web before rebooting A. III and IV only B. I, II, and III only C. I, II, and IV only D. I, II, III, and IV$$$$ Answer: C The OS patch overwrites the OEM SCSI and NIC drivers. We could avoid this problem by: • reinstalling the SCSI and NIC drivers after the patch was applied. (I) • Not overwriting never files. (II) • Upgrading OEM drivers before rebooting. We should replace all overwritten files before rebooting since that would nullify the OS patch.

A company experienced a drive failure on one of its email servers and lost all of the data. The company decided to modify the RAID solution on all of its email servers. The servers are currently using RAID 0 on a set of six disk drives. The new solution will of RAID 5 on a set of six disk drives. Which of the following is most likely to result from the new solution? A. The solution will create redundancy B. The solution will not create redundancy. C. The solution will create redundancy and improve disk reads only. D. The solution will create redundancy and improve disk read/writes.

Answer: A RAID-5 uses one hard drive for parity so it creates redundancy. The parity drive would decrease both read and write performance compared to a RAID 0 (disk striping).

Which of the following external connection types provides the fastest interface? A. SCSI B. RS-232 C. IEEE-1394 D. USB

Answer: A SCSI is the fastest interface by a huge margin. It is almost 8 times faster than IEEE-1394 for example. SCSI-4 (Ultra320) has a maximum speed of 320MB/s. 1394 can transmit data at up to 400 megabits per second, more 30 times the speed of USB. Reference: Server+ Certification Training Kit, SCSI Terminators and Timing Microsoft article: IEEE 1394: The Time is Right for This Bus

A company has hired an installation service company to install a server. The SCSI devices are configured to use the same SCSI controller. The installation appeared to be successful. After six hours, the server's SCSI devices are randomly inaccessible. A reboot temporarily resolves the issue. Which of the following is the most likely cause of this issue? A. The devices were not properly terminated. B. The system's BIOS was not upgraded prior to installation. C. The SCSI adapter is not properly seated in the PCI slot. D. The SCSI adapter firmware was not upgraded prior to installation.

Answer: A SCSI trunks need to be terminated. If it is not terminated it could cause the behavior above. If a BIOS upgrade would be required, the SCSI adapter not properly seated in the PCI slot, or the SCSI adapter firmware required update, then SCSI adapter would not work for six hours.

Several users have had problems accessing the company's intranet server named SERVER1. A technician has attempted to ping the server and receives the following message: C:\ ping server1 Unknown host server1 Which of the following should be done next? A. Try to "tracert server1". B. Reboot the intranet server. C. Reload the TCP/IP protocol stack on the server. D. Put the server in the local machine's host table.

Answer: A Several users, but not all users, have problem accessing SERVER1. This indicates that it is a local problem. If ping fails we already know that tracert would fail. However, the tracert command could show where in the path between the client and the server the error occurs. The clients could have an incorrect default gateway setting or a router may work incorrectly. Since it is very easy to test a tracert command it seems like the best troubleshooting step to try next. Incorrect Answers Since only some of the users have this problem there is no need to make any changes on the server: there is no need to reboot the server or reconfigure the TCP/IP protocol on the server. There could be a name resolution problem. The client may not be able to resolve the host name server1 to an IP address. We could add a mapping from Server1 to the IP address of server at the local hosts file on the clients. However, this would require considerable administrative effort. Furthermore this file is not known as a host table.

A customer is using a DAT drive for data backup. The drive will backup intermittently, usually stopping towards the end of the backup job. The customer claims to have cleaned the drive just two days ago, but the problem still exists. What should be the next step in troubleshooting the backup problem? A. Ask the customer to replace the backup tapes. B. Ask the customer to reload the backup tapes. C. Replace the tape drive with a known good drive. D. Replace the controller with a known good controller.

Answer: A Since the backup jobs stops at the same point it seems likely that the backup media is corrupted and should be replaced.

A failure occurred while a full backup from a tape set was being restored to a server. During a second attempt, the restore failed at the same point. Which of the following is most likely the cause of the failure? A. One of the tapes has failed B. The tape backup unit is dirty C. The tape drive malfunctioning D. All tapes in the backup set are corrupt

Answer: A Since the failure occur at the same point it seems likely that the backup media, one of the tapes, has failed.

Answer: A The BIOS setup would show all detected CPUs.

On Monday morning many users find they are unable to log into the network. The server technician has been at work over the weekend and has no trouble connecting from his workstation. The server is apparently up and running fine. The NICs on the failing workstations have link status-lights lit. Which of the following actions will most likely correct the problem? A. Restart DHCP. B. Replace the hub. C. Update workstation client software. D. Replace the patch cable between server and hub.

Answer: A The DHCP service might have been stopped. This would explain why the server technician is able to connect from his workstation. DHCP is initiated when the OS is started and his computer has been online during the whole weekend. Restarting the DHCP service could solve the problem. Incorrect Answers Some users are able to connect so it does not seem to be any hardware or cabling problems. There should be no need to replace either the hub or cabling between the hub and the server. It seems unlikely that we suddenly would be some problem with the workstation client software.

A UPS needs to be purchased to protect two new servers that have been ordered. Which of the following is most important to consider when purchasing the UPS? A. VA rating. B. UL rating. C. Clamping voltage. D. Length of the UPS cord.

Answer: A The Volt Ampere (VA) rating of the UPS is the most factor when decide which UPS should be acquired. Note: How to decide which UPS that would be adequate. Determine the volt amp (VA) required for all of the equipment. This is done by adding the amperes drawn by the equipment and multiplying the total by the output voltage. Add roughly 15% to allow for future growth and round up to the nearest VA rating available in the product series you have selected.

Before installing new, pre-tested server hardware, a technician performed the following tasks: Inventoried the hardware, checked the HCL, and checked the network port. Upon startup of the system, the UPS starts beeping. Which of the following did the technician fail to verify? A. The available power. B. The presence of a UPS serial cable. C. The KVM (Keyboard Video Mouse) installation. D. The temperature of the room is within proper parameters.

Answer: A The available power is not enough. Incorrect Answers The lack of UPS serial cable would not make the UPS beep when the system is started. KVMs does not influence a UPS in any way, they are used to control several servers from a single keyboard, mouse, and monitor. The temperature of the room will not cause the UPS to beep.

A technician is configuring a new server CTIA45 in the "comptia.org" domain using the IP address of 10.10.10.50 with a subnet mask of 255.255.255.0 and a gateway address of 10.10.10.1. The technician is unable to ping the other servers by the IP address. Which two of the following are possible causes and solutions? I. The other servers are on the same segment, but using a different subnet mask. Correct the subnet mask by making it match the other servers. II. The DNS hostname entered into the new server is incorrect. Use a different hostname. III. The other servers are on a separate segment and the gateway address is incorrect. Correct the gateway address. IV. The other servers have DNS entries, but the new server does not. Add a new entry to the BIND host file A. I and III B. I and IV C. II and III D. II and IV

Answer: A The client could have an incorrect mask or an incorrect default gateway (or an incorrect IP address). Since the ping attempts does not use host names there is no name resolution problem. The problem is not DNS related.

A server manager logs into a server with his administrator account and installs a third-party diagnostic tool. No installation problems were encountered. Upon starting the tool for the first time, and error code is displayed that is difficult to understand. The manager attempted to reinstall the tool, but received the identical error. Which of the following actions is the most appropriate next step to resolve the problem? A. Review the application documentation. B. Search the Network OS support Website for the specific error code. C. Review the server performance logs for an easier-to-interpret error code. D. Install the latest Network OS service patch to correct recently identified bugs.

Answer: A The error is specific to the diagnostic tool. Reviewing the application documentation would be the next step to resolve the problem.

A file server is experiencing a dramatic increase in memory pages per second and a simultaneous decrease in CPU utilization. Which of the following is most likely the cause? A. The server's CPU cache is malfunctioning. B. The server is running out of virtual memory. C. The server is running out of physical memory. D. The server's processor is inadequate for the task.

Answer: A The increase in memory pages/second normally indicates that the server is running out of physical memory. This would also cause an increase in the CPU utilization since the CPU would have to swap content between the physical memory and the virtual memory. But in this scenario a decrease in CPU utilization is reported instead. This indicates that there is some problem with the CPU, possibly a malfunctioning CPU. The malfunctioning CPU is causing the increase in memory pages per second.

A network server will not boot properly. The server never begins the load of the Network OS and the server technician suspects a POST error. What is the proper way to use a POST diagnostics hardware adapter? A. Insert the card into an open bus slot, boot the computer, and the error codes will display on the adapter. B. Insert the card into an open bus slot, boot the computer, and the error codes will output on the default printer. C. Insert the card into an open bus slot, boot the computer using the supplied floppy disk, and the error codes will be stored on disk. D. Connect the adapter to a serial or parallel port, boot the computer, and the error codes will be stored in a memory buffer created by the adapter.

Answer: A The messages, the post codes, from the POST diagnostics hardware adapter would be shown on a display on the adapter.

A server had two 64-MB DIMMS and a 256 MB DIMM was added. After installing the additional memory, POST errors are generated. What is the most likely cause of the failure? A. 64 MB DIMMs and 256 MB DIMMS are not compatible. B. The server's existing memory is slower than the new memory. C. The server has both registered and nonregistered memory installed. D. POST messages are normal when mixing DIMM capacities.

Answer: A The most likely problem is that the 64MB and the 256MB are not compatible. Incorrect Answers Different memory speeds would not be a likely problem. The faster memory would run at the slower speed. Memery does not have to be registered in order to function. POST messages are not a normal with any type of memory.

A technician must perform a pre-installation check prior to installing a new server that required downloading the most recent BIOS and firmware. What is the best resource for acquiring the BIOS and firmware? A. The vendor's Website B. The vendor's UDP site C. A list server resource D. The Network OS Website

Answer: A The motherboard manufacturer, the vendor, should have the most recent BIOS and firmware at their Website.

In a mixed protocol environment, a local server is viewable throughout the LAN, however, it cannot connect to the Internet. Which of the following diagnostic tools should be used first to determine where the problem exists? A. Ping 127.0.0.1 ensure TCP/IP stack is functioning. B. Check the error log file of the server to determine what errors have been received. C. Use the NSLOOKUP command to determine what host name should be used to access the Internet. D. Check the system error log file and the network file to determine if any errors have been encountered.

Answer: A The network may use some other network than TCP/IP on the local network. We must ensure that TCP/IP, the protocol of Internet, is properly installed and functioning.

Which of the following should be done to ensure the redundant hardware components will be functional in the event of a failure? A. Simulate a hardware failure. B. Check the system and health logs for the appropriate systems. C. Remove each redundant component and test them in a test server. D. Remove each component and test them individually with a multimeter.

Answer: A The redundant components should be tested in order to ensure that they would be functional in the event of failure. The most realistic test would be to simulate a hardware failure and check if the redundant hardware will work.

A technician is called to perform maintenance on a server. While performing his tasks, he notices that the tape backups are located on a bookshelf outside the server room. Which of the following recommendations, if any, should be made to the system administrator? A. The tapes should be stored in a lockable cabinet outside the server room. B. The bookshelf should be moved inside the server room. C. The tapes should be stored in a secure offsite location. D. No recommendation is necessary. This is a common practice to allow quick access in the event of a server failure.

Answer: A The tapes should not be publicly accessible. Where the tapes should be stored depends on several factors that are not listed in this scenario: • Is the access to the server room restricted? • What type of backups are stored in the cabinet? • Do the company store some backups off-site already? However, it seems most prudent to recommend that the tapes should be stored in a lockable cabinet outside the server room. Incorrect Answers Moving the bookshelf inside the server room might not help if access to the server room is not restricted. The tapes might be daily backup tapes that are rotated during the week. The company may already have an offsite storage procedure for backup tapes. Public access to the backup tapes is unacceptable. We must make a recommendation.

After a full backup has completed for the previous day, which of the following would be the most effective method of verifying that the backup tape is useable for restoring the data? A. Use the backup software "verify" option. B. Read the contents of any text file directly from the backup tape. C. View the backup session log file to verify all directories and files are present. D. Restore sample data to verify success of the backup.

Answer: A The verify option of the backup software is the most effective method to check the integrity of the backup tapes.

A company has a new disaster recovery requirement. It states that the media have minimum five-year storage life and capability to back up their 80 GB database. Which of the following technologies would provide the best solution for this company? A. DLT B. CD-RW discs C. WORM discs D. QIC-80 Tapes

Answer: A There are DLT tapes and DLT tape drives that supports up to 120 GB of data (or more). Incorrect Answers CD-RW and WORM discs does not even support 1GB, typically 650-800MB. QIC-80 tapes might be able to store 1GB, but nowhere near 80GB.

A server exists in a remote location. Last week as service/daemon on the server crashed, and while the application fault was logged, no one in the IT department noticed it. Major departmental functions were affected. Which of the following would have allowed the problem to be recognized immediately? A. Implementing systems management software. B. Routinely logging into the server using remote software. C. Routinely monitoring server health, system, and application logs. D. Enabling automated system recovery to bring server down after service/daemon halts.

Answer: A To immediately be notified by any failed or crashed network services we must configure alerts. Systems management software is needed to implement this. Incorrect Answers Routinely checking server status would improve the detection but it would not immediately alert administrators of the occurring problems. An automated recovery system could handle many errors and bring the system online after a crash. It would not be able to restart from all problems, and it would not make the administrators aware of the problems immediately.

A company's main server uses an Ultra2-compatible controller with six Ultra2-compatible devices correctly installed and terminated. The technician is required to install and configured two Ultra3 devices. Which of the following is the most likely result? A. The new devices will work at Ultra2 speeds after they are configured. B. The Ultra2 controller will not allow the new devices to be installed. C. The Ultra3 devices are not compatible with the Ultra2 controller and require an adapter. D. All devices will function correctly after the cable length is reduced to include the new devices.

Answer: A Ultra3 devices are down-compatible with Ultra2 controllers. The Ultra3 devices would work at Ultra2 speeds.

A business owner wants a recommendation on who should receive access to secure server rooms. Which of the following is LEAST likely to be recommended for having access to server rooms? A. Users B. System administrators C. Data entry supervisors D. Database administrators

Answer: A Users should not have access to the server room.

A Magic Packet is a packet that contains 16 contiguous copies of the receiving network adapter's MAC address. What technology utilizes this concept? A. WOL (Wake-On-LAN) B. CLC (Cluster LAN communication) C. SMTP (Simple Mail Transport Protocol) D. SNMP (Simple Network Management Protocol)

Answer: A Wake On LAN (WOL) is the name for a technical development jointly created by IBM and Intel. The technology allows "enabled" devices to be powered on remotely via a special type of network communication. A WOL-enabled device, when powered off, will still draw a tiny amount of electricity to drive the network interface. The interface remains in a passive, listening mode, sending nothing out on the network. To wake up the device, a specially formed packet is sent to the network port where the device is plugged in. This special packet, called a magic packet, carries a special "signature." When the network interface sees this signature, it recognizes this as a wakeup call.

The Vice President of Operations has decided that the company should be running the latest version of the Network OS. A decision was made that the existing Network OS should be removed before the new version is installed. A full backup has been performed. Which of the following should be done first? A. Verify the backup B. Format the system drive C. Partition the data drive D. Install the latest Network OS updates.

An existing UPS has succeeded in preventing immediate, unplanned shutdown, but the run time on a fully-charged battery is too short for a clean shut down of the Network OS. What step should be taken to improve the amount of available battery run time? A. Install a higher capacity UPS. B. Increase the charge time on the UPS. C. Connect the UPS to a dedicated circuit. D. Configure the advanced power management on the server.

Answer: A We must replace the UPS with an UPS with increased battery time that will ensure that the server can be shut down gracefully. Incorrect Answers Changing the charge time or connecting the UPS to a dedicated circuit would not increase the available battery run time. The advanced power management on the server can be configured for an unattended operating system shutdown in the event of an extended power outage. The advanced power management cannot be used to improve the amount of available battery run time in any way though.

Determine whether the Network OS is corrupted. B. Determine whether the first hard disk crashed. C. Check that the SCSI adapter is seen at POST. D. Verify that the DMA is not set to the "on" position.

Answer: B The first hard disk could have crashed. We must check this possibility. Incorrect Answers The error message indicates a problem with the hard drive, not any problem with the OS. The POST does not check for SCSI adapters. SCSI adapters are checked after the POST. Furthermore, we do not know if they server use any SCSI adapter. This is not a DMA problem.

A system administrator has been notified twice this week that an application has failed, causing a critical server to crash. The server has generated an output file. He decided to run a set of performance monitors on the server to evaluate what is the most likely cause of the crash. What else should be done, if anything, to aid in problem determination? A. Cluster the server with another for load balancing. B. Send the output file to the application group or vendor for analysis. C. Move the application to a new server with more RAM and a faster processor. D. Do nothing, because it is probably an anomaly and is unlikely to happen again.

Answer: B The output file could be send either to the application developer or to the OS vendor for further analysis. This could be costly however. Incorrect Answers Clustering is used for failover workload distribution. Clustering would not solve any problem with a critical server. More RAM and faster processor would improve performance, but moving the application to another server not aid in determining the cause of the crash. The problem has already occurred twice. It is not anomaly.

Create a large swap partition. C. Use a RAMDRIVE to provide virtual RAM. D. Use the EMM386.EXE /NOEMS command at startup.

Answer: B UNIX and LINUX systems, contrary to Windows systems, use a swap partition. The size of the swap partition determines the ability to increase the size of the virtual memory. Incorrect Answers Text files are parsed. For example do compilers parse program source code before producing program code. A swap file cannot be parsed. Windows 3.x used RAMDRIVE and EMM386.EXE for memory handling. UNIX does not use these utilities.

During the setup of a new site, an external Ultra2 RAID storage unit is to be installed. Which of the following is NOT likely to cause a problem when the external RAID storage unit is installed? A. Using passive termination on the enclosure. B. Using a SCSI cable between one and five meters in length. C. Attaching the subsystem to the server while it is powered up. D. Powering off the RAID subsystem when the server is turned on.

Answer: B Ultra2 can use a cable up to 12 meters in length. A SCSI cable between one and five meters would not cause a problem.

A server currently uses an Ultra2 SCSI controller. A directive to install an Ultra ATA 100 drive is ordered by management. Which of the following reasons would prevent a technician form using this drive? A. Ultra2 to Ultra 100 requires a converter. B. Ultra2 does not support Ultra ATA 100 drives. C. Ultra2 uses a 50-pin connector; Ultra ATA 100 uses 68 pins. D. Ultra2 uses an 80-pin connector; Ultra ATA 100 uses 40 pins.

Answer: B Ultra2 is a SCSI controller, but Ultra ATA 100 driver is an IDE drive. SCSI and IDE are incompatible.

A customer asks a technician to install a new Ultra2 SCSI controller to an existing server. The new controller will replace a Fast SCSI controller that is in the server. The only device that will be connected is a Fast SCSI external tape drive. The customer will want to add new SCSI devices in the future. What should the technician tell the customer? A. The new configuration will work, however Ultra2 devices may operate at single-ended speeds. B. The new configuration will work and Ultra2 devices will operate at Ultra speeds. C. The new configuration will work and all devices will operate at Ultra2 speeds. D. The new configuration will not work.

Answer: B Ultra2 is compatible with existing SCSI devices allowing older, non-Ultra2-capable controllers to be used with newer, Ultra2-capable devices and vice versa.

What is the bus length limitation of a single-ended UltraWide SCSI with four devices? A. 1.5 meters B. 3 meters C. 6 meters D. 12 meters

Answer: B UltraSCSI supports four devices, up to 3 meters (10 feet). UltraSCSI supports eight devices, up to 1.5 meters (5 feet).

A customer has complained about repeated network failures. The server's network cable is frequently found lose or disconnected. Which of the following solutions is NOT appropriate solution to the problem? A. Replace the cable connector. B. Solder the cable to the server. C. House the server in a lockable cabinet. D. Restrict access to the server to administrators.

Answer: B We could replace the cable connecter, or make the cabling inaccessible by using a lockable cabinet or restricting access to the server to administrators. We should solder the cable to the server as it would be awkward to replace the cable or the network adapter of the server in case of failure.

Three servers connected to a KVM (Keyboard Video Mouse) switch are to be installed in a rack. What is the minimum number of standard network cables, KVM cable sets and monitors needed to support this configuration? A. 1 standard cable, 2 KVM cable sets, and 1 monitor B. 3 standard network cables, 3 KVM cable sets, and 1 monitor C. 1 standard network cable, 3 KVM cable sets, and 3 monitors D. 3 standard network cables, 4 KVM cable sets, and 1 monitor

Answer: B We need a network cable and a KVM cable set for each server. The KVM enables use a single keyboard, mouse and monitor for all servers.

A customer uses a 24 GB DAT drive for backup purposes. The drive has been intermittently failing during backup jobs. To resolve the problem, the customer cleaned the drive and purchases new DDS-3, 120m tapes. The drive now fails on all jobs. Which of the following will most likely resolve this problem? A. Use compatible media. B. Replace the tape drive. C. Replace the SCSI controller. D. Clean the drive additional times.

Answer: B We need to replace the tape drive. The other alternatives does not apply. Incorrect Answers DDS-3 can store 24GB of data. DDS-3 tapes can be used in 24GB DAT drive. It is not likely that the SCSI adapter should have failed. Additional cleaning of the drive would not help.

When the installation of a new server is planned, using which of the following is most likely to result in the greatest number of problems when the operating system is installed? A. Untested memory B. Third-party NICs and SCSI controllers C. Server listed on Network OS vendor's HCL D. Drivers supplied by Network OS instead of hardware vendor

Answer: B We should avoid third-party NICs and SCSI controllers. We should use the ones recommended and tested by the server manufacturer. Incorrect Answers Untested memory could cause problems but it is not the most likely cause. It would be good, not bad, if the server was listed on the OS vendor's HCL. The latest drivers should be obtained from the hardware vendor. The drivers supplied by the OS vendor have been tested with the OS and should be adequate most of the time.

A small company owns a file server that shuts down frequently. After a great deal of troubleshooting, the server technician discovers the system is overheating and that there is a large buildup of dust in the server. What can be done to improve reliability? A. Use compressed air to clean out the server. B. Clean the server and set up a cleaning maintenance schedule. C. Obtain an air compressor and use it to clean out the server. D. Bring in his vacuum from home and use it to clean out the server.

Answer: B We should clean out the server and ensure that in the future we do it on a regular basis.

Some of the users on a customer's network are complaining that they cannot access some servers. Which of the following would be LEAST appropriate question to ask upon arriving onsite? A. Which servers are not available? B. When were the servers last rebooted? C. Which users are unable to access the server? D. Are any users able to access the unavailable servers?

Answer: B We should focus at the problem at hand: some users cannot access some servers. The question of when the servers were last rebooted is not so relevant.

A server technician discovers that a drive in a RAID 5 array has failed during the night. The array was protected with a hot-spare drive. What is the best first step in restoring the RAID array to its pre-failure state? A. Rebuild the RAID 5 array. B. Assign another drive as the hot spare in the array. C. Replace the defective drive. D. Verify completion of rebuilding of RAID array to the hot space.

Answer: B We should: 1. Replace the failed drive. 2. Rebuild the RAID 5 array.

While performing a daily review of the system logs, a server manager notices that the latest error entry in the log indicates that a specific service or function has stopped operating. What should be the next diagnostic step taken by the server manager? A. Attempt to manually restart the service or function. B. Examine the log for previous instances of this error. C. Determine which enterprise functions are being affected by this stoppage. D. Erase the log to make it easier to locate the next occurrence of this error.

Answer: B We want to diagnose the problem. We should try to locate the source of the problem. A good first step is to check the system logs for similar event that has occurred earlier, maybe locating the first occurrence and possibly what cause the first occurrence. Incorrect Answers A manual restart of the service (or function) might start the service (or function) but it would not help diagnosing the cause of the problem. Determine which enterprise functions that are affected by this problem might be a good precaution. It would not, however, help to diagnose the problem. The log contains information that could be helpful for diagnosing the problem. The log must not be erased.

When a multi-homed server is installed, it is sometimes necessary to block TCP/IP traffic between each subnet. Which of the following actions will accomplish this? A. Add an SNMP trap B. Disable IP forwarding C. Remove IPX and NetBEUI D. Put the cards on the same subnet but use different IP addresses.

Answer: C A LAN analyzer would be able to analyze the packets on the network. We would be able to obtain the source of the packets.

An external SCSI hard drive has been added to a file server. The hard drive has been configured to use an available SCSI ID. The SCSI controllers BIOS is unable to see the drive. Which of the following actions should be performed first to resolve the issue? A. Reinitialize the drive B. Low-level format the drive C. Check and reconfigure termination if necessary D. Change the SCSI ID to the lowest available number

Answer: C A SCSI segment must be terminated. This is the first we should check.

The previous month's UPS activity log that is maintained for a server is reviewed. It shows power to the server is repeatedly being lost for about 10 minutes at approximately the same time every Friday night. All system hardware and software diagnostic tests have been unable to locate the cause of the problem. Who should be contacted regarding the problem? A. The UPS manufacturer. B. The department manager. C. The building maintenance foreman. D. The company's outside server consultants.

Answer: C A building maintenance foreman seems the most likely cause of the problem. He probably shut down some system at the same time each Friday night. It seems very unlikely that the department manager or the consultants would work Friday night, or that UPS manufacturer would schedule the UPS to perform a specific reoccurring activity.

When the functionality of a new UPS connected to a server is tested, the UPS does not perform as expected. The new system is configured to wait one minute and implement an orderly shutdown. The computer remains on several minutes until the UPS loses power and shuts down abruptly. Which of the following should be checked to determine the cause of the problem? I. A DMA conflict II. Conflict from a serial mouse III. Bad battery array IV. Incorrect polarity setting A. II only B. I and III only' C. II and IV only D. III and IV only

Answer: C A conflict from a serial mouse could prevent communication between the UPS and the OS. This would prevent a clean shut down. Wrong polarity setting (e.g. positive instead of negative) can make the UPS alert service not work. Instead of getting warnings and a clean shutdown, you'll get an abrupt power off when the juice is gone from the UPS. Incorrect Answers UPS devices use an IRQ and not any DMAs when communicating with the OS. The battery array in this scenario is not bad, since it the UPS gives the system power for several minutes.

While installing a new server, a server technician performed the following actions: • Inventoried the server hardware components • Downloaded and applied the latest BIOS and firmware • Loaded the Network OS and patches The tape drive failed initialize during Network OS startup. Which of the following is most likely causing the failure? A. The tape drive device driver was not enabled in the system BIOS. B. The Network OS patches were not applied correctly. C. The tape drive is not on the Network OS HCL. D. The BIOS and firmware upgrades were not properly applied.

Answer: C A failed installation of a device could be explained by an incorrect or old driver (not listed here) or by a device that is incompatible with the OS (not included on the HCL).

After the four pieces of equipment listed below were connected, the UPS went into an overload condition. Which of the following pieces of equipment is the most likely cause of the problem? A. Desktop system B. 17" monitor C. Laser printer D. 48-port hub

Answer: C A laser printer should never be connected to an UPS since a laser printer consumes a lot of power when it print pages. This would cause problems for the UPS.

A new server has been installed at the main complex of a company. • By pinging the local gateway from the new server, a server technician has verified the presence of a good LAN connection. • Users from a remote site cannot connect to the new server but can connect to all other servers at the remote site. • When the technician tries to ping the remote site from the new server, it times out. • The IP stack was removed and reinstalled but that did not help. • When pinging the router at the remote site from the new server, it also times out. Which of the following is the most appropriate action to take? A. Enable DHCP on the server. B. Wait for the new server to be recognized by the routers. C. Inform the network administrator responsible for routers. D. Plug the network cable into a different port in the switch.

Answer: C A misconfigured or faulty router could explain the problems. Incorrect Answers The server can ping the local gateway so it has proper IP configuration. There is no need to configure it as an DHCP client. Routers do not recognize servers or computers. They recognize other routers. The server can ping the default gateway so the connection to the switch works already.

A client has identified a room to install a new server rack. Which of the following environmental issues is LEAST critical to the server specialist? A. Heavy dust on the floor. B. Discolored ceiling tiles. C. A painted concrete floor. D. Overhead sprinkler system.

Answer: C A painted concrete floor would have little or no environmental impact. Discolored ceiling tiles could indicate a water leakage which could be very harmful to computers. A dusty environment could be harmful to the servers. A sprinkler system cannot be accepted in a server room.

A file server has been optimized with the following characteristics: • 1 GB RAM • 400 MHz CPU • 10/100 Ethernet NIC • Hardware RAID subsystem The server needs to be reconfigured as a database server. Which of the following upgrades should be added first? A. More RAM B. An additional NIC C. An additional processor D. An additional tape drive

Answer: C A single 400 MHz CPU could become a bottleneck on a database server. We should either add an additional CPU or replace the CPU with a faster one. A database server needs a lot of RAM, 1 GB should be sufficient. A 10/100 Ethernet NIC should be sufficient. A database server has less network traffic compared to a file server for example. A tape drive is only used for recovery. It is not required since SQL Server can make backups over the network.

A technician tasked with creating backup procedures needs to provide a company with a backup plan. Which of the following provides minimal risk of data loss in the event of a hard drive failure? A. Weekly full backup. B. Daily incremental with weekly full backup. C. Daily differential with weekly full backup, D. Weekly full backup to a remote data facility.

Answer: C A weekly full backup with daily differential backups provides minimal risk of data loss. Incremental backups are somewhat less secure since all incremental backups since the last full backup are required, but a differential restore only requires the last differential backup.

ESD (Electrostatic Discharge) can be reduced by installing: A. A UPS. B. A dehumidifier. C. Adequate grounding. D. Fluorescent lighting.

Answer: C Adequate grounding, for example a grounding mat, would reduce ESD. Incorrect Answers An UPS would not prevent ESD. Dry air can cause ESD. Humidifier, not dehumidifier, is used to decrease ESD: Fluorescent lighting has no impact on ESD.

A customer reports that the new server shows only one of the two installed PCI Ethernet controllers. They request a service call to have one of the controllers replaced. Before ordering the replacement controller, which of the following actions should be taken first? A. Remove the drivers for the controllers and reinstall. B. Update the controller's drivers to the latest version. C. Remove each controller to determine the faulty controller. D. Examine controller configuration data and vendor specifications.

Answer: C Before replacing the faulty controller we must be sure we replace the correct one. Incorrect Answers We have already decided to replace the controllers. It is too late to reinstall or update the driver of the controller. It would also be a waste of time to check the controller's configuration data and vendor specifications.

In the event of a single-drive failure of an array, which of the following should be the first step to recovery? A. Break the mirror B. Restore from backup C. Determine the RAID level D. Replace the failed drive

Answer: C Before starting the recovery of the array we should determine the RAID level. Then we will know if we should break the mirror (RAID 1), or replaced the failed drive. 25 When files on an NTFS partition on a new server were configured, an error occurs and the server will no longer boot. Which software is required to recover from the failure and continue configuration? A. Novell NetWare CD-ROM B. Unix Boot/Root diskette(s) C. IBM OS/2 Startup disk and Installation disk D. ERD and/or installation disks with CD-ROM$$$$ Answer: D NTFS is only used on Windows NT/2000/XP systems. These systems can be restored by use of the installation CD-ROM/boot disks combined with the ERD diskettes.

A Customer wants to add memory to an existing server while preserving their initial investment. Which of the following actions must be performed before purchasing memory? A. Check memory count on POST. B. Verify pin count of replacement memory. C. Verify the availability of memory slot. D. Verify compatibility with existing memory.

Answer: C Before the purchase you should first check if there the server has available memory slot. The next step would be to check which memory are compatible with the existing memory.

Which of the following types of backup media is recommended to maximize storage on a 24 GB DAT drive? A. DDS-1 B. DDS-2 C. DDS-3 D. DDS-24

Answer: C DDS-3 supports 24GB DDS-1 supports 2.6GB and 4GB. DDS-2 supports 8GB. DDS-4 supports 40GB. DDS-24 is standard used by Sony. It supports 24GB but might not be compatible with a 24GB DAT drive. Note: DAT stands for Digital Audio Tape, an audio recording technology based on 4mm wide tape in a helical scan recorder. DDS - Digital Data Storage - was developed from DAT concepts to store computer data with high data density and high reliability. However, many people continued to call DDS drives "DAT drives," and the name is still with us today.

Two physically identical servers were acquired. One will be used for a mail server and one for a file server. Both servers were loaded from the same media. Immediately after installation, the system administrator noticed that each server has a Network OS executable file of slightly different size. Which of the following conclusions is most appropriate? A. This is a dynamic file. B. The file is infected with a virus. C. The serves' hard drive sector sizes vary. D. The disk controller is failing on one server

Answer: C Different sector sizes would give different file sizes.

A company that has expanded from two servers to ten servers continues to perform daily full backups. The company would like to significantly reduce the amount of time used to backup the systems, while having the shortest possible restore time in the event of failure. Which of the following solutions would best fit the company's needs? A. Maintain the current solution of daily full backups. B. Perform an incremental backup every Monday through Sunday. C. Perform a full backup every Monday and a differential backup Tuesday through Sunday. D. Perform a full backup every Monday and an incremental backup Tuesday through Sunday.

Answer: C Differential backups are quicker than full backups since they only backup information that has changed since the last full backup. Restoring a differential backup is fast as well. First we restore the full backup and then we restore the last differential backup. Incremental backups take more time to restore.

An operating system vendor has just released a new patch on its Website. Which of the following should be done before installing the patch on the production server? I. Read the manual that came with the system. II. Test the patch on a test system. III. Download the patch and install it on the system. IV. Verify the system has the type of problem the patch fixes. A. I and IV only. B. II and III only. C. II and IV only. D. I, III, and IV only

Answer: C Explanation: I. We should read the documentation of the patch, but we do no review the manual of the system. II. We should test the patch before putting it into a production environment. III. We should not immediately download and install the patch. IV. The patch might not apply to the needs of this particular server.

After Microsoft Windows NT or Windows 2000 is installed, which of the following is the best step to take in order to optimize virtual-memory speed? A. Place the Pagefile.sys on the slave hard drive. B. Enlarge the Win386.swp file to twice the physical RAM size. C. Place the Pagefile.sys file on a separate hard drive from the operating system. D. Decrease the minimum size and increase the maximum size of the Pagefile.sys file.

Answer: C Explanation: In Windows NT/2000/XP the pagefile is named Pagefile.sys. Moving the pagefile away from the system partition to a separate disk would increase performance since data can be read in parallel from the system disk and the pagefile disk. Incorrect Answers A: Putting on a slave drive would not have any particular benefits compared to use it on a master drive. B: Legacy Windows OSes like Windows 9x and Windows 3.11 use the Win386.swp file. This file is not used in Windows NT/2000/XP/.NET. D: The default page file size configured by the OS is best for most computers. There would be need to reconfigure the minimum and the maximum size of the Pagefile.sys file.

An engineer at TestKing has installed an SMP-compliant Network OS on a dual-processor server. The BIOS detects two processors, but only one processor is recognized by the Network OS. Which of the following actions should be performed to enable the second processor? A. Apply the latest Network OS patches. B. Update the BIOS to the current version. C. Configure the Network OS kernel for SMP support. D. Update the stepping level on the second processor.

Answer: C Explanation: The Network OS kernel must be configured for multiprocessor support. On Windows 2000/XP/.NET computers this is referred to as replacing the Hardware Abstraction Level (HAL). Incorrect Answers A: The OS has multiprocessor support since it is SMP-compliant. B: The BIOS already detects both CPUs. D: We don't need to configure the second processor.

A database server named TestKingDB is receiving a RAID controller upgrade. The new controller is identical to the existing controller, except that it has a larger cache buffer with its own battery backup. The network administrators report that they currently perform nightly differential backups of the server. Which of the following is NOT required before the RAID controller is upgraded? A. Backup to tape. B. Verify the backups. C. Change cache policy. D. Schedule server downtime.

Answer: C Explanation: There is no such thing as cache policy as far as RAID controllers are concerned. Incorrect Answers A: We should let the backup process finish. B: We should verify the validity of the backup before making a major change of the server. This would enable us to revert to the previous state. D: We must take the server down and should schedule the replacement at the next server downtime.

A file server and monitor are connected to a fully charged UPS. UPS software was configured on the server to systematically shut down after 20 minutes of power less. During a 60-minutes power outage, the server and monitor both powered off after 35 minutes. Why did the server not systematically shut down? A. The UPS was improperly sized for this configuration. B. A standard RS232 cable was used to attach the UPS to the filer server. C. The Network OS software did not contain the required service patches and upgrades. D. The monitor's power cord was plugged into the back of the server. The monitor experienced a power surge causing the server to reset.

Answer: C Explanation: This seems to be a communication problem between the UPS and the server. It could be software related. Incorrect Answers A: If the UPS was improperly sized and not have enough capacity it would shut down before the 20 minutes interval. B: Most UPS devices connect to the server through a serial cable. RS-232 is standard serial interface. D: There server was shut down after 35 minutes. It should have been shut down within 20 minutes. Event though you should not put the monitor in the UPS the monitor was not cause of this problem.

A server technician is upgrading the following components in a server: Internal Devices: • A video adapter. • A network adapter. External Devices: • An external modem. • An external tape backup unit. When should the technician load drivers and test them? A. After each device is installed. B. After all devices are installed. C. After all internal devices are installed, then again after all external devices are installed. D. After the video adapter is installed, then install the remaining devices, load drivers and test again.

Answer: C Explanation: We should start by installing the internal devices. We then verify that the internal device drivers are ok. Then we install one external device one at a time and verify that it is functioning correctly before installing the next device.

An onsite technician is at a client's site to perform a warranty replacement of a FRU (Field Replacable Unit) in Novell IntranetWare 4.11 server. The technician is unsure of how to shut down the server properly. When calling into the help desk, the technician inquired about which commands should be entered before powering off the server. Which commands should the help desk tell the technician to use? I. Shutdown II. Exit III. Down IV. Killservices A. I then II B. II then III C. III then II D. IV then I

Answer: C First we must down the server with the DOWN command, then we exit to DOS with the EXIT command. We DOWN command must precede the EXIT command, not vice versa. Note: NetWare 4.11 console commands DOWN - Shuts down Server activity EXIT - Returns to DOS after the server has been DOWN(ed)

A remote email alert has been created to inform three key network personnel when any drive in a RAID array fails. While reviewing recent system events, one technician did not receive email alerts. Which of the following best explains why this happened? A. The email server is down. B. The technician is not on the same subnet. C. The technician's email address is misspelled. D. The technician is not logged on as an administrator.

Answer: C His email address could have been misspelled. Incorrect answers A downed email server would affect other people as well. There is no requirement to be on the same subnet to receive emails or alerts. There is no requirement to be logged on as an administrator to receive emails or alerts.

A hot-plug PCI card needs to be replaced in a server supporting this technology. Before replacing the card, which of the following actions, if any, must be performed before removing the card from the server? A. Shut down the server. B. Unplug the power cord from the server. C. Remove power to the expansion slot. D. No action is required.

Answer: C Hot plug PCI cards can be deactivated, allowing for removal and replacement of a PCI card while the system is in operation. Power should be removed from the expansion slot before removing or inserting the PCI card. Incorrect answers Hot-pluggable PCI cards can be replaced while the server is running. There is no need to shut down the server or unplug the power cord from the server. Power should be removed from the expansion slot before removing or inserting the PCI card.

When planning an installation of a server, Network OS, and a third-party device, the technician notes that the third-party hardware is not on the Network OS vendor's HCL. Under which of the following circumstances would the technician proceed with the installation? A. The third party device is Plug-and-Play. B. The server hardware vendor is manufactured of the device. C. The device manufactured provides a driver for that Network OS. D. The Network OS HCL lists a similar device from the same manufacturer.

Answer: C If the network adapter manufacturer provides a device driver for this particular OS it is likely that the adapter would function without any further problems even though it is not listed on the HCL.

What troubleshooting limitation is created by using vendor-specific systems on the hard drives of a server (NTFS, HPFS, Ext2FS)? A. They are not recoverable after a crash. B. Data cannot be recovered from a corrupt volume. C. Log files are not compatible for troubleshooting tools. D. Local access is available only from within the Network OS.

Answer: C If we use a vendor-specific file system we can only access the locally with the vendor OS. Incorrect Answers If the network OS support the file system then it would be able to recover from a crashed drive or recover from corrupt volumes which use that vendor specific file system. File formats might be compatible even if the file systems are incompatible.

Which of the following is the most important element of an effective disaster recovery plan? A. A clear plan for reducing the effects of a disaster. B. Adequate personnel to implement the disaster recover plan. C. A clear and concise disaster recovery plan stored in hard copy. D. A well-documented list of specific vendors used by the company.

Answer: C It always starts with having a concise disaster recovery plan as you cannot count on having the right personnel to implement it. Incorrect answers: The final step in a good disaster recovery plan is training. You need to train your personnel in what the plan is, how it is executed, and how it needs to be maintained. Training is perhaps the most critical yet most neglected task. It helps ensure that new risks and solutions are put into the plan and that everyone knows what is expected when a disaster occurs.

A technician performs daily backups. The backup solution contains a verification tool for every backup. A file server experienced catastrophic failure. Recovery attempts failed. Which of the following can be done to minimize the risk of this happening again? A. Install a UPS. B. Replace the verification tool. C. Develop a plan to test backups. D. Install vendor patches for the verification tool.

Answer: C It is not enough to verify backups. The backups should be tested as well.

A server technician must move a company's two loaded 42U racks to a new location in the building next door. Which of the following is the best way to accomplish this move? A. Load the rack onto a wheeled trolley and move the rack to the new location. B. Lower the wheels on the rack, raise the rack feet and move the racks to the new location. C. Remove all equipment from the rack and move the racks and equipment to the new location. D. Unload enough heavy equipment from the rack to be easily moved and move the racks to the new location.

Answer: C It would be safer to move the racks and the equipment separately.

What is the main benefit of using backup tools supplies by the Network OS vendor? A. Speed of operation B. Backup media availability C. Compatibility with operating system D. Advanced features over third party programs

Answer: C Network OS vendor Backup tools are often integrated directly into the operating system. The same vendor should guarantee compatibility.

RAID and system logs are showing that a drive in a RAID 5 array is reporting PFA (Predictive Failure Analysis) drive failures. Which of the following steps should be taken? A. Use the backup program to copy all the data from the drive to the tape. Replace the drive. Restore all of the data from the tape. B. Use a cloning utility program to create an exact mirror image of the drive. Replace the drive. Restore the cloned image to the next drive. C. Use the RAID utility program to "fail" or take the drive offline. Remove the drive. Replace with a new drive. Using the RAID utility program, rebuild the RAID 5 array. D. Use the RAID utility program to "fail" or take the drive offline. Remove the drive. Replace with a new drive. Using the RAID utility program, rebuild the RAID 5 array. Restore the data in the array from the latest backup.

Answer: C PFA alerts us that a disk in the RAID-5 is having problems. We should fail that drive, remote it, replace it with a new drive, and rebuild the RAID 5 array (this is possible thanks to the parity bit).

Users report that the intranet database is slow to respond during peak use times. The database server is on a small 150-user network and is configured with dual processors, 512 MB RAM and a hardwarecontrolled RAID 5 array with three drivers. The server also provides DNS and DHCP services for the intranet. Which of the following changes can be made to help improve server performance? I. Set process affinity II. Add a hard drive to the RAID 5 array III. Move the page file to another partition on the RAID 5 array IV. Move the DNS and DHCP services to another server A. I and IV only B. II and III only C. I, II, and IV only D. I, II, III, and IV

Answer: C Processor affinity can be used to enable the database server service to exclusively use one processor. This would improve performance. Adding a hard drive to the RAID 5 array would improve disk access since three drives containing data (one contains the parity bit), instead of two, could be read in parallel. Removing any network services from the server would improve the performance of the remaining services. Incorrect Answer Move the page file on the RAID 5 array would not change the performance. The OS uses the RAID 5 array as a single drive.

A server crashed where the data was locally stored on a RAID 0 configuration. According to the organization's disaster recovery plan, data should be recovered via disk fault tolerance strategies before going to the tape archive. What should be done to recover the lost data? A. The data is safe. Replace the failed disk and regenerate the mirror set. B. Replace the failed disk in the RAID array and it will regenerate itself automatically. C. Replace the failed disk in the RAID array and restore data from the most current backup. D. Replace the failed disk when it is convenient, because a copy of the data is on a disk on the second RAID controller.

Answer: C RAID 0, disk striping, does not include any fault tolerance. We must restore the data from the most current backup.

A server error indicates that a service or driver failed during system startup. When a technician tries to start the service manually, it again fails to load and displays a specific error code. Which of the following is the most appropriate next step to resolve the problem? A. Reinstall the current patches. B. Reboot the server and observe any real-time errors. C. Determine if other services or functions also failed to start. D. Reinstall the service from the original install disks and apply appropriate patches.

Answer: C Services are often dependant of other services. We should initially determine if other services or functions also failed to start. This could help use to find the cause of the problem. We should start by checking the system logs. Incorrect Answers We should not start by reinstalling the current patches. Instead we should try to locate the source of the problem. Rebooting the server and checking for any errors could be useful, but most likely no further information would be gained by this. Initially we should try to locate the source if the problem instead of reinstalling services or applying patches.

At a company with a file server and a router for Internet access, a user reports that the network is down. None of the users can print or retrieve files. Last night, the company has some work done on the air conditioning ducts in the ceiling. The technician checks the server, router, and hub and everything appears normal. He plugs his laptop into the hub and has no problem connecting, opening, and printing files. What would be the likely explanation for this situation? A. DHCP is not working. B. There are bad ports on the hub. C. The network cabling is damaged. D. Users are not logging into the LAN.

Answer: C Since work were performed on the air conditioning ducts, which often contain network cabling, the work could have damaged the network cabling. Incorrect Answers Everything appears normal at the server. The network services, including the DHCP service, should be up and running. Bad hub ports would not affect all users. Users know how to log on to the network. Not all users would forget this at the same time.

As the server is powered on, POST errors are observed. How can it be determined which FRU (Field Replacement Unit) to replace? A. Review the Network OS logs for subsystem errors B. Power off the server, disconnect from power, reconnect, restart. C. Look up the error codes in the server documentation for the appropriate part to replace. D. Contact the server manufacturer's technical support for known failing components that should be replaced.

Answer: C The POST error codes have to be decoded, for example by using the server motherboard documentation.

A server has lost two disks on its data array running RAID 5. The company deploys a Grandfather- Father-Son (GFS) backup rotation using incremental backups during the week. The company's disaster recovery plan stipulates any data that cannot be recovered from local tape resources must be acquired from the offsite tape storage location. The incremental backup was completed on Wednesday night, shortly before the server crashed. Backup media is still available locally. Which of the following is the best procedure to recover the data? A. The tapes should be recovered from the onsite facility using tapes from Friday's full backup and Wednesday's incremental backup. B. The tapes should be recovered from the offsite facility using Friday's full backup and Wednesday's incremental backups. C. The tapes should be recovered from the onsite facility using Friday's full backup and Monday, Tuesday, and Wednesday's incremental backups. D. The tapes should be recovered from the offsite facility using Friday's full backup and Monday, Tuesday, and Wednesday's incremental backups.

Answer: C The local tapes are still available. We are able to use the local tapes. We are only required to use offsite tapes if data cannot be recovered from the local tapes. We must start to restore the full backup followed by each incremental made after the full backup in order.

A new UPS has been installed with a signal cable that connects the server to the UPS. However, the server cannot communicate with the UPS. Which of the following is the likely cause? A. The UPS is the wrong model. B. The UPS batteries are not fully charged. C. The UPS software is not properly configured. D. The UPS is not configured to a power source.

Answer: C The most likely cause is that the UPS software has not been properly configured. Incorrect Answers A wrong model is not a likely problem, since there are standards for UPS. The batteries do not have to be fully charged in order for the UPS to operate. An UPS need a power source, though it is not likely that this have been overlooked.

A Wake-on-LAN adapter has been installed on a server. However, the server does not wake up as expected. Which of the following should be done to resolve the problem? A. Verify SNMP packets B. Verify TCP/IP packets C. Verify Magic Packets D. Verify ACK packets

Answer: C Wake On LAN (WOL) is the name for a technical development jointly created by IBM and Intel. The technology allows "enabled" devices to be powered on remotely via a special type of network communication. A WOL-enabled device, when powered off, will still draw a tiny amount of electricity to drive the network interface. The interface remains in a passive, listening mode, sending nothing out on the network. To wake up the device, a specially formed packet is sent to the network port where the device is plugged in. This special packet, called a magic packet, carries a special "signature." When the network interface sees this signature, it recognizes this as a wakeup call.

When a new disaster recovery plan is reviewed, which of the following should be done first? A. Test the existing plan. B. Identify critical resources at the department level. C. Determine the preventive measures to be taken to minimize risks. D. Assess the possible amount of down time that could be experienced.

Answer: C We are still reviewing the plan, so there shouldn't be any hardware or equipments to test. Even if there are equipments in place, reviewing the plan are paperwork job, so we need to analyse first, once finished from the plan we can do the test.

The file servers regularly download antivirus updates from the vendor's FTP server. The automatic updates have not occurred on these servers for the last three updates. Which of the following actions should be taken to isolate this problem? I. Verify connectivity to the vendor's FTP server. II. Ping another server on the network. III. Check the server logs for errors. IV. Reboot the server to restart all services. A. I and II only B. II and IV only C. I, II, and III only D. I, II, III, and IV

Answer: C We could verify the connectivity of these servers. We should check both the connectivity with the vendor and local connectivity. (I and II) We should also check the server logs for any related errors or warning. (III) Rebooting the server and restarting all services should only be used as a last desperate attempt. It would not be particularly useful for isolating the problem.

A technician performs a full backup of the file servers every Monday at 7:00 PM. The tapes are sent to an offsite storage center the following morning. He uses one tape per server. Differentials are performed daily throughout the rest of the week at 7:00 PM. One of the servers fails Saturday at 5:00 PM and must be recovered. What would be the best course of action? I. Restore the Monday Full backup tape. II. Restore all of the previous week's Differential backup tapes. III. Restore the Friday Differential backup tape. IV. Restore the Saturday Differential backup tape. A. III only B. I and II only C. I and III only D. I and IV only

Answer: C We must first restore the full backup. Then we only need to restore the last differential backup since each differential backup includes all changes made since the last full backup.

Two servers need a connection between them to establish a heartbeat monitor for a software monitoring tool. The System Administrator requests that COM1 be used on each server to establish this connection. This technician must obtain a cable to accomplish this task. Which of the following types of cables is most likely to be used? A. DB9 cable B. IEEE-1284 cable C. Null modem cable D. Standard serial cable

Answer: C We need a null modem cable, a twisted serial cable, to connect two computers using the serial (COM) interface.

A technician is verifying a pre-installation plan that calls for a RAID 5 array with a hot spare. The RAID 5 array must be able to store a slow-growing database, currently containing 20 GB of data. The server technician receives four SCSI drives (each 5 GB in size) and an external hot-swappable drive enclosure. The technician needs to report on the availability of the RAID 5 array to support the plan. Which of the following, if anything, is needed for this installation? A. One additional 5 GB drive. B. Two additional 5 GB drives. C. Three additional 5 GB drives. D. The current configuration is acceptable.

Answer: C We need to support a 20GB slow-growing database on a RAID 5 array. The RAID 5 array must include one hot spare drive. We cannot use exactly 20GB for the database since it slowly growing. We must use five 5 GB drive, which gives 25GB, to store the data. Then we need one drive for parity and one drive as a hot spare. In total we need seven 5GB drivers. Currently we have four drives, so we need three additional drives: two for the RAID 5 array, and one for the external hot-swappable drive enclosure. Note: To add more redundancy, you can assign one hot-spare drive to one array or to a set of arrays. This hot spare will replace a failed drive and become part of the RAID 5 array until the failed drive is replaced. This permits two failures in any given array without any loss of data.

Users suddenly lost connectivity to an existing server. The server technician can ping the loopback address and the server's own IP address. However, no other device on the network can be pinged. The LAN cable is plugged in. Which of the following should the server technician check next? A. The router. B. The subnet mask. C. Link integrity. D. The DNS server.

Answer: C We should check the simple possible causes of the problem first. Broken, disconnected, improperly terminated, or mis-wired cables are responsible for over 70% of all LAN problems. We check physical connectivity with the link integrity. A green LED indicating good link integrity should be on at the server end, and on the port of the hub where the server is connected. Note: The IEEE Ethernet standards make use of a feature called 'Link Integrity' to ensure that the physical cable being used to transmit/receive data is intact. Incorrect Answers. A malfunctioning router could explain that no other computers can be reached, but we should check the link integrity first. The server's subnet mask would not change by itself. Since the PING by IP address fails there is no name resolution problem at hand. The DNS server cannot be blamed.

A customer has three identical servers (WEB_01, WEB_02, WEB_03) configured in their web farm. Downtime has been scheduled for the web farm on Friday evening.

Update WEB_02 and Web_03 to the same version monitoring agents. B. Disable the agents on WEB_02 and WEB_03 until they can be updated. C. Configure the agent on WEB_01 to communicate with the older agents on WEB_02 and WEB_03. D. No action is required.WEB_02 and WEB_03 will be automatically updated.

Answer: C We should configure the updated monitoring agent to communicate with the older agents. We should not be forced to upgrade the agents on the other web servers.

After a technician installed software on a mission-critical server, the server experienced errors reported to a log file during boot. Which of the following is the best process to determine a course of action? A. Delete the log file and see if the problem happens again? B. Ignore the log file and test the application, verifying proper operation. C. View the log file and the documentation from the previous technician for recent work done to the server. D. Refer to the vendor's Web-bases knowledge base. If no answer is found, submit a bug report to the vendor.

Answer: C We should first examine the log file. We should then examine the server documentation for any recent work on the server which could be the cause of the errors.

A working server's monitoring tool identifies a problem with a PCI NIC in the server. Which of the following steps should be performed next? A. Assign an IRQ to the card. B. Move the card to another slot. C. Install an identical spare card. D. Install a PC diagnostic tool in the server.

Answer: C We should replace the card with an identical card. The identical card should work immediately since it uses the same device drivers. Incorrect answers A: An IRQ problem seems unlikely since the NIC used to work. B: Moving the card to another slot would most likely not change anything. D: It is simpler and more straightforward just to replace the card, compared to installing and using additional diagnostic software.

Two of the server's data disks in a customer's RAID 5 array fail. The Network OS is mirrored on a separate drive set and RAID controller. According to the company's in-place disaster recovery plan, all data should be restored from onsite tape before recovering from tape stored at the offsite storage location. A full backup and two incremental backups were performed before the crash. What must be done to return the system to operational status? A. Replace the two failed disks in the array so the array will start to regenerate itself. B. Replace the two failed disks in the array, and then use the last incremental backup to restore the data. C. Replace the two failed disks in the array, and then use the full backup and one incremental backup to restore the data. D. Replace the two failed disks in the array, and then use the full backup and all (two) incremental backups to restore the data.

Answer: D A RAID 5 disk array can recover from one failed disk, but not from two or more failed disks. We need use tape backups. We must restore the full backup, followed by all incremental backups applied in the correct order. In this scenario we must apply both the incremental backups.

27 Users complain that around 3:00 PM each workday, the company's email server operates slowly. What should be done first to determine the cause of the slowdown? A. Check the pagefile size. B. Add more RAM to the server and do a new baseline. C. Do a network trace to determine any issues with the network. D. Check logs to determine when maintenance programs are scheduled.

Answer: D Since the disturbance reoccurs at exactly the same time of the day, it seems that some scheduled task, possibly a maintenance program, is the cause of the problem.

A user would like to increase network bandwidth to the server. Which of the following technologies would NOT provide bandwidth? A. Multi-homing B. Load balancing C. Port aggregation D. Subnetting

Answer: D Subnetting would decrease network traffic by dividing the network into subnets. It would not, however directly increase the network bandwidth to the server. Incorrect Answers Multihoming is achieved by installing more than one network adapter on the server. This will increase the network bandwidth to the server. Load balancing would increase the performance of the server. The server and it load balancing partners would be able to process more network traffic. Port aggregation is the combining of two NIC ports with one IP address. This enables fault tolerance and optimize server availability. It also increases network bandwidth.

When the location of a server is planned, the power source should be checked for which of the following? I. AC Voltage II. DC Voltage III. Amperage IV. Ground A. I and IV only B. II and III only C. II and IV only D. I, III, and IV only

Answer: D The AC voltage (not DC voltage), the amperage, and the ground should be checked when deciding the placement of the server.

A technician is adding a PCI 2.2-compliant 64-bit, 66-MHz card to a server. Which of the following types of slots can be used for the card? I. 32-bit, 33 MHz PCI II. 64-bit, 33 MHz PCI III. 64-bit, 66 MHz PCI A. III only B. I and II only C. II and III only D. I, II, and III

Answer: D The PCI 2.2 specification allows for a 64-bit, 66-MHz compliant card to be used in a 32-bit 33Mhz slot, in a 64-bit 33MHz slot, or in 64-bit 66MHz slot.

An installation plan requires plugging a 64-bit, 66 MHz, PCI 2.2-compliant SCSI controller into a 32-bit, 33 MHz PCI slot. Which of the following steps, must be performed? A. Nothing can be done. 64-bit, 66 MHz cards are not backward-compatible with 32-bit, 33 MHz slots. B. 64-bit cards are already compatible with a 32-bit slot. Bus speed compatibility must be set with a jumper on the PCI card. C. Remove the perforated cutout on the edge connector of the PCI card. This will allow a 66 MHz card to be plugged into a 33 MHz slot. D. Do nothing. The 64-bit, 66 MHz card is compatible with the 32-bit, 33 MHz slot.

Answer: D The PCI 2.2 specification ensures that a 64-bit 66MHz cards can be used in a 32-bit, 33MHz PCI slot. The slot can be used by the card.

Which of the following factors must be considered when deciding which UPS to install? A. Maximum load B. Processor load C. Primary transformer output D. Acceptable downtime

Which of the following is the best time to be considered for this analysis? A. During non-business hours B. During server-backup periods C. During planned maintenance periods D. During average network utilization

Answer: D The baseline should be established during average network utilization.

A functional server suddenly stops responding to users. Upon a cold reboot of the server, the screen is blank. However, the hard drive and CD-ROM spin up normally. What is most likely causing the problem? A. There is a virus problem. B. There is an AC power problem. C. There is a hardware problem. D. There is a software problem.

Answer: D The behavior could be caused by a virus, a hardware problem, or a software problem. The most common cause of this is a software problem though.

A small company is backing up mission-critical data and wants to implement a disaster recovery plan. The network administrator is tasked with developing the disaster recovery plan. Which of the following should be the first step in developing the plan? A. Practicing the disaster recover drills. B. Exploring disaster prevention techniques. C. Create a step-by-step restoration plan. D. Determining the Information Technology configuration.

Answer: D The first step in developing a disaster recovery plan is to determine what the risks to your business operation are. In order to evaluate the risks we need to determine the present Information Technology configuration. Incorrect Answers Practicing the disaster recover drills, training, should be the final, not first, step in a good disaster recovery plan. Exploring disaster prevention techniques has no place in a disaster recovery plan. We want to have a plan how to recover from a disaster, not how we prevent a disaster. Creating a step-by-step restoration plan should be included in the restoration plan, but not as the first step. We need to determine the risks first.

A company's server room flooded and five years of data were lost. Server administrators implemented a disaster recovery plan before the flood that included a backup process with a daily tape rotation schedule. Which of the following would have best minimized the impact of the flood? A. Establishing a cold site. B. Establishing remote notification for flooding. C. Installing a raised floor in the server room. D. Storing backup tapes at an offsite location.

Answer: D The impact of the flooding would be minimized if the tapes were stored at an offsite location which presumable would not be affected by the flooding.

A server that has been running for several months was scheduled for maintenance and the latest operating system patches was applied. Upon reboot, the message that "No operating system found" was shown. What is the most likely cause? A. The master boot record has been corrupted. B. The file system has been corrupted by a virus in the patches. C. The RAID configuration has not been synchronizes in some time. D. The operating system patches overwrote the OEM driver for the drive controller.

Answer: D The last change made on the server made before the reboot was the installation of the latest operating system patches. It seems like that the error is related to that. The patches might have overwritten the OEM driver for the drive controller.

A client desires to install a dial-up server for remote access to allow 100 telecommuters to logon to the network for daily file transfers. Which of the following deployment consideration is LEAST critical to successful deployment? A. Adequate power source. B. Availability of modems. C. Availability of active phone lines. D. Availability of Virtual Private Network (VPN).

Answer: D The remote access server must have an adequate power source, there must be enough modems to support many simultaneous connections, and there must be available active phone lines. VPN would increase security but is not strictly required. VPN is more common for connections through the Internet.

A company has a pair of servers: a primary server and a secondary server for failover. The primary server is backed up and verified on a routine basis. Both servers are on a UPS. Which of the following should be done to insure maximum system reliability? A. Install redundant NICs in the primary server. B. Create SNMP traps to report server hardware failure. C. Install redundant heartbeat links between the servers. D. Routinely test the secondary server in the production environment.

Answer: D The secondary server should routinely be tested in the production environment.

After Network OS installation, the clients can log into the new server, but cannot ping the server. Any of the following may cause problem EXCEPT A. There server has no DNS entry. B. TCP/IP is not loaded on the server. C. There is no entry in the HOSTS file. D. The ping daemon is not loaded on the server.

Answer: D There is no such thing as a ping daemon. The 'ping' command generates "ICMP echo request" packets (ICMP is the "internet control messaging protocol"). There is no daemon that generates the ICMP echo replies. Those are generated by the kernel. Note: A daemon on a UNIX/LINUX system is approximately the same thing as a service on a Windows system. Incorrect Answers A name resolution problem, for example a missing entry in the DNS zone or in a HOSTS file, could prevent a computer from pinging the server by name, but it would still be able to logon to the server using the IP address of the server. There could be another network protocol in use instead of a TCP/IP. The Ping utility only works with the TCP/IP protocol.

A third-party RAID card has been upgraded to the latest drivers. Since the upgrade, when a cold boot is performed, the connected hard drives are correctly discovered during POST and will boot after a power down, but not after a warm boot of the server. An identical card gives the same results. Which of the following sources of information would be most useful in resolving this problem? A. The Network OS vendor's HCL B. The Network OS vendor's Website C. The server vendor's Website D. The adapter vendor's Website

Answer: D This seems to a software problem since the network adapter works when the OS is cold booted, but not when you warm booted. The information concerning this problem could possibly be found on the Network OS Website, the server vendor's website, or the adapter vendor's website. Most information on the adapter would most likely be found on the adapter vendor's Website.

Of the following actions, which is the best way to create a server baseline? A. Run an SNMP agent continuously for a week. B. Run an SNMP agent at random times each day during the week. C. Run performance monitoring software continuously for 72 hours. D. Run performance monitoring software at the same time each day for a week.

Answer: D To establish a baseline we should monitor the performance with monitoring software (system monitor on Windows 2000/XP systems), not running an SNMP agent. We should try to monitor typical network performance. It is not necessary to continuously monitoring the system for a prolonged amount of time. Instead we should monitor at several occasions.

A customer who needs to restore their system from tape has been creating differential backups since their last full backup. How many tape sets will be required to restore the system to the most recent backup? A. One, the full backup. B. One, the last differential backup. C. Two, the full backup and incremental backup. D. Two, the full backup and the last differential backup.

Answer: D To restore from a differential backup we must first restore the full backup and the restore only the last differential backup.

The Network OS on a server has recently been updated. Some of the hardware on the system is no longer operating. Which of the following should be done to fix the problem? A. Reinstall the old Network OS B. Replace the hardware in question. C. Test the hardware on another system. D. Check for drivers specific to the new Network OS.

Answer: D To solve the problem, to make the hardware work on the new OS, we should check for the latest device drivers for the new Network OS.

Which of the following connectors are used on SCSI cables? I. 68-pin VHDCI. II. 36-pin Centronics III. 50-pin Centronics IV. 68-pin High Density A. I and III only. B. II and III only. C. I, II, and IV only. D. I, III, and IV only.

Answer: D VHDCI, Sometimes called SCSI-5. Very popular in RAID cards 68-pin High Density Centronics C50: Incorrect Answer: 36-pin Centronics is a printer interface, not a SCSI interface.

A company wants to install an internal Ultra3-compatible controller with two external Ultra2-compatible tape devices. The technician requests two 50-pin cables and two passive (132 ohm) external terminators. Which two of the following must be done to accomplish the installation? I. Change the controller to an Ultra2 compatible. II. Change Tapes devices to UltraWide compatible. III. Change cables to 68-pin cables IV. Change terminators A. I and II B. I and IV C. II and III D. III and IV

Answer: D We must use the 68-pin connector for the Ultra2 devices. We must replace the 50-pin connector. Passive termination use 132 ohm terminators. Passive termination is an older technology which cannot be used with Ultra2 or Ultra3. Incorrect Answers Ultra3 is backward compatible with Ultra2. There is no need to replace the Ultra SCSI controller.

A customer asked for 83 hard drives to be used by all four of their database servers. Which technology would best achieve this configuration? A. SCSI B. IEEE-1394 C. Ultra DMA D. Fibre Channel

Answer: D We need to cluster the hard drives so that they can be used by all four database servers. Only the SCSI and Fibre channel technology should be considered. Windows 2000 Clustering services, as an example, only supports SCSI and Fibre channel hard drives in a cluster. To support 83 hard drives we should use Fibre channel, since a single Fibre channel supports up to 126 devices. Note: Fibre Channel is a high performance interface designed to bring speed and flexibility to multiple disc drive storage systems. Incorrect answers The SCSI interface would be inadequate with as many as 83 hard drives. SCSI wide can support only 15 devices. ULTRA DMA is an IDE standard. IDE drives are not ordinarily used to cluster hard drives. Only two IDE devices can be used on a single IDE channel. By default, a computer has only two IDE channels. IEEE-1394 (firewire) can support up to 63 devices. It would not, however, be an appropriate solution for hard drives for database servers. IEEE is typically used for external hard drives. IEE-1394 is comparatively slow with a maximum speed of 400 megabits/s. Reference: Seagate knowledge base, Fibre Channel MCSE Training kit (70-223) Microsoft Windows 2000 Advanced Clustering Services, Configuring the Shared Storage Device, page 44. Microsoft Article: IEEE 1394: The Time is Right for This Bus

A company server is connected to a RAID 5 storage subsystem. A drive failure occurs and goes unnoticed. Three weeks later, an additional drive fails and all data is lost. Which of the following would have prevented the array failure? A. Using hot-swappable drives. B. Performing regular tape backups. C. Flashing the RAID controller BIOS. D. Enabling remote notification of the drive failure.

Answer: D We should have enabled remote notification of drive failures. This would have notified the administrator as soon as the first disk in the RAID 5 array failed.

A drive in a RAID 5 array has failed. The administrator was not aware of this issue. Users complained about server access being slow. What is the most efficient method of alerting the administrator about the drive failure? A. Enable event logs B. Configure remote notification C. Schedule daily hardware visual checks D. Enable Network OS alerts on drive enclosure

Answer: D We should make sure that the administrator should be notified one disk in the RAID-5 array has failed. This will be established by enabling the Network OS alerts on drive enclosure. Note: The vendor-supplied software will be able to monitor the drive cabinet and report on failures, such as power supply or drive failures. The information provided by the drive cabinet's monitoring software is not otherwise available to the server until a failure occurs. This early warning is important if you have established a RAID array for fault tolerance, because the array is still susceptible to a drive enclosure failure if more than one of the drives in the array is located in the enclosure. Incorrect answers Event logs would not immediately notify the administrator of the problem. He would have to check the log files on a regular basis. Remote notification would not inform the administrator of a failure of disk in a RAID-5 array. The OS would only be able to detect if the RAID-5 disk fails. We must use the monitor software in the Drive Cabinet. Daily hardware checks would not minimize administrative effort. A more automatic approach is preferred. Reference: Server+ Training kit, Installing a Drive Cabinet

A fan-cooled server rack cabinet contains three servers and a UPS. The temperature in the cabinets is always significantly higher than the room temperature. Which of the following activities would offer the best solution for lowering the temperature inside each of the server cases? A. Take the case covers off the three servers. B. Install an additional cooling fan to each server. C. Install a higher performance CPU fan in each server. D. Increase the airflow through the rack cabinet with better fans.

Answer: D We should replace or add better fans to the rack cabinet. Incorrect Answers Removing the case covers could decrease the air flow and make the problem worse. Adding better cooling fans to the rack is a more practical solution than replacing or adding fans on each server.

When a performance baseline was created, a peak of 100% CPU utilization was observed more than once. The performance sample was taken at 5-second intervals during normal business hours. The application response time has been acceptable. Which of the following is the most likely reason for this server behavior? A. The CPU is probably faulty. B. The system behavior is normal. C. The server is unable to handle the required load. D. The baseline has to be taken over a 24-hour period.

Answer: D We should take longer samples. Too short samples could give a false view.

A server hardware technician has installed a new NIC in a server, connected the correct network cabling, and installed the driver included with the NIC. After rebooting the server, the NIC does not function. The technician reviews the vendor's installation manuals and repeats the installation procedures. The technician further confirms that the installation procedure taken was correct, but that the NIC still will not function. Following best practices, what is the next best step to correct this problem? A. Remove and reinstall all network protocols. B. Reseat the NIC by removing and reinstalling the card. C. Remove the defective NIC and return it to the manufacturer. D. Search the NIC manufacturer's Website for software patches and updates to the installation guide.

Answer: D We should try to find the latest device driver (or software patch/update) at the NIC vendor's web site.

A customer has a system with two 9-GB drivers that are hardware mirrored on an Ultra SCSI RAID controller. Using the same size drivers, they would like to plan for 63 GB of storage space. Which of the following would offer a solution with the highest performance? A. RAID 5 with 7 additional drives B. RAID 5 with 12 additional drives C. RAID 0/1 with 7 additional drives D. RAID 0/1 with 12 additional drives

Answer: D We should use RAID 0/1 combines RAID 0 (disk mirroring which gives fault tolerance) with RAID 1 (disk striping which give highest performance). 6 additional drives could be used on each mirror. Seven -9GB drives give a 63GB striped volume as was required. Incorrect Answers RAID 5 also provides fault tolerance but not as high performance as RAID 0/1. 7 additional drives in a RAID 0/1 is not enough to provide 63 GB of storage space. 12 additional drives are needed.

When a RAID 5 array is established, which of the following will provide the fastest read solution? A. 3 drives, 10 GB each B. 5 drives, 6 GB each C. 5 drives, 10 GB each D. 10 drives, 3 GB each

Answer: D With RAID 5 the number of drives decides the read performance. Since the data is read in parallel from all drives, the more drives available in the RAID 5 array the more data can be read and the better performance is achieved.

A server room contains 15 servers, a 16-port hub, and a patch panel. All of the equipment is on four folding tables. Each server has its own monitor, keyboard, and mouse. All cables are routed behind the tables and around the perimeter of the room. Which of the following recommendations should be made for improving the server room? I. Install a KVM (Keyboard Video Monitor) switch II. Install a network switch III. Install a set of server racks IV. Improve cable routing A. I and II only B. III and IV only C. I, II, and IV only D. I, III, and IV only

Answer: D With a KVM switch we only need a single monitor, keyboard and mouse, not a separate set for each server. This would safe space and resources. Server racks make better use of the space. Cable routing should be improved. The cables should be routed behind tables and around the perimeter of the room. Incorrect answer A network switch could improve network performance, but could not be considered an improvement for the server room.

A technician is trying to determine why a remote alert failed on a server at another location. Which of the following steps should be performed to fix the problem? I. Reboot remote server. II. Connect to the remote server. III. Logon with administrator privileges. IV. Determine that the alert criterion is configured correctly. A. I and II only B. III and IV only C. I, II, and IV only D. II, III, and IV only

Answer: D/ The hard drive in an organization's certificate authority server has failed. The drive contained the certificate database and certificate revocation list. A replacement hard drive and the appropriate backup tapes from the Grandfather-Father-Son (GFS) rotation are obtained. What should the server technician do first before attempting a restore of the system? A. Burn in the new hard drive for at least 24 hours. B. Check the certificate authority's Website for software updates. C. Locate the organization's server recovery plan. D. Determine the default server configuration from the certificate authority's software guide. $$$$ Answer: C The server recovery plan, if existing, would be the first to check for the service technician when an import server has failed.

Since simulating hardware failure is risky, in case the server may never be required. T/F? A. TRUE B. FALSE

B - The only way you can be sure of how the backup will perform is when the crash actually happens. As a preventive maintenance task, you may set up a schedule to check for these failures at regular intervals.

79. What connector is used to provide power to a PATA drive? A. Berg connector. B. Molex connector. C. 15-pin connector. D. Word connector. $$

B The connector used to power a PATA drive is the Molex connector. The Berg connector is used to power floppy drives. The 15 pin connector is used to power SATA drives. There is no such thing as a word connector.

12. What is the problem with most fireproof safes being used for magnetic media? Choose all that apply. A. Safes cannot adequately hold all the magnetic media. B. Safes were designed for paper products. C. After a disaster, it could be weeks before the safe is located. D. Some safes degauss magnetic media.

B and C. Fireproof safes cannot adequately protect magnetic media because they are typically designed to protect paper products. Tapes melt much sooner than paper ignites. Even specially designed safes may not work because fires are unpredictable and they may burn longer and hotter than expected. For more information see the "Fireproof safes" section.

1. Most companies are not ready for a disaster because of which of the following barriers? Choose all that apply. A. Lack of knowledge B. Little funding C. Lack of appreciation by support personnel D. Not enough support from management

B, C, and D. Typically funding, lack of appreciation, and gaining management support are the biggest barriers faced by disaster recovery planners. It is essential to obtain this support for the DRP to be a success. Answer A is incorrect because lack of knowledge is not a problem if you have any sort of involvement with backing up data and taking care of the corporate information systems. For more information see the beginning of the chapter.

12. When installing an external SCSI daisy chain, where is termination needed? (Choose two.) A. On every device. B. On the last device. C. On the first device. D. On the SCSI adapter. E. On the motherboard. $$

B, D. Termination is required on the last device. Since there is no internal SCSI daisy chain, the other end of termination is handled by the SCSI adapter automatically. Termination is handled only on the last device. If termination occured on every device or on the first device, the other devices after the first device would be unable to participate in the SCSI chain.

19. The hard drive on the server is extremely busy all the time. What could the administrator do to resolve the problem? (Choose two.) A. Replace the hard drive. B. Add more RAM. C. Reinstall Windows. D. Install more fans. E. Defragment the hard drive. $$

B, E. The hard drive undergoing excessive loads indicates one of three things. Either there is not enough RAM on the server, the hard drive on the server is severely fragmented, or there is an excessive amount of requests to read and write to the hard drive. Replacing the hard drive will not correct the underlying cause. Reinstalling Windows doesn't make much sense as it would result in down time for the users. Installing more fans doesn't make sense as there is no indication this is a cooling problem.

13. A server with a coaxial Thinnet network card has just been installed. How should the server be connected to the network? A. The coaxial cable should be plugged into the coaxial adapter on the network card. B. A BNC T-connector should be installed on the network card connector, with one end connected to the network and the other end terminated. C. The network cable should be pierced with a vampire tap. D. A BNC barrel connector should be connected to the server, with the other end connected to the network.

B. A BNC T-connector is needed to connect the server to the network and terminate the connection. Answer A is incorrect because the network cable needs to be terminated. Answer C is incorrect because a vampire tap is typically used for older Thicknet installations. Answer D is incorrect because a barrel connector will not terminate the network connection. For more information, see the "Coaxial" section.

17. A firewall server has been configured to allow only inbound HTTP Web access to an internal Web server, while HTTP, FTP have been enabled for outgoing connections from the internal LAN to the Internet. To prevent inbound HTTP connections from reaching other local LAN devices, what else should be configured? A. Proxy B. DMZ C. DNS D. DHCP

B. A DMZ should be used to isolate the Web servers from the internal user network. Answer A is incorrect because a proxy server forwards HTTP requests from internal clients to external Websites. Answer C is incorrect because a DNS server resolves Internet Domain names to IP addresses. Answer D is incorrect because a DHCP server assigns IP addresses to devices on the network. For more information, see the "Installation Strategy" section.

2. A customer wants to be able to connect an array of 55 hard drives to their two database servers. Which technology should be used for this system? A. IDE B. Fibre Channel C. SCSI D. Disk striping

B. A Fibre Channel system is best suited for this complex arrangement. Answer A is incorrect because IDE cannot handle this many hard drives. Answer C is incorrect because Fibre Channel should be used for such a high-end system. Answer D is incorrect because disk striping refers to a method of RAID implementation, not a hardware technology. For more information, see the "Fibre Channel" section.

13. A new Ethernet LAN network is being added to a current LAN that is running Token Ring. What type of server or device should be used to connect the two networks? A. hub B. bridge C. firewall D. LAN adapter

B. A bridge connects two different types of networks together. Answer A is incorrect because a hub can only connect two networks of the same types. Answer C is incorrect because a firewall is used to protect the internal LAN from external Internet traffic. Answer D is incorrect because there is no such thing as a LAN adapter. For more information, see the "Installation Strategy" section.

5. Your boss is looking at replacing the old air conditioning system with a newer one. She would like to know what the best system would be. What would you recommend? A. A central station air handling unit B. A complete self-contained package unit with remote condensers C. A window-mounted air conditioner D. A chilled water package unit

B. A complete self-contained package unit with remote condensers is the best choice for an air conditioning system. They are available with up or down discharge. Answer A is incorrect because central station air handlers are typically used in office environments and not computer rooms. Answer C is incorrect because there should not be any windows in the server room for security reasons, and this type of system does not have the proper environmental controls for server rooms. Answer D is incorrect because a chilled water package is not a complete self-contained unit. For more information, see the "Air conditioning" section.

21. Which of the following describe a server that helps send and receive emails? A. A dedicated application server. B. A distributed application server. C. A print server. D. A DHCP server.

B. A distributed application server is used by email applications to distribute email messages to end users. A dedicated application server is a server that is dedicated to performing a single task like DHCP or DNS.

10. A customer would like to provide access to their new SNA mainframe from their current Windows workstations. What device will be needed to allow connectivity? A. bridge B. gateway server C. router D. DNS server

B. A gateway server will be needed to allow the Windows machines access to SNA services. Answer A is incorrect because a bridge will only connect two different networks, it will not provide gateway services. Answer C is incorrect because a router will only route packets between two networks. Answer D is incorrect because a DNS server is used to resolve Internet domain names to IP addresses. For more information, see the "Installation Strategy" section.

18. A 10Base2 network is suffering from frequent network problems. There are 30 workstations hooked together in a bus topology. The server's network card was replaced a week before, as it was deemed to be faulty. What is the most likely cause of the problem? A. The new server network card only supports 100 MB/s. B. The terminator on the server is loose. C. One of the workstations is configured for UTP. D. A client workstation is configured for token-ring.

B. A loose terminator on a bus topology network will result in connectivity problems for the entire network. Answer A is incorrect because the network speed is not an issue. Answer C is incorrect because there should be no UTP devices on a coaxial network. Answer D is incorrect because the network is specifically a 10Base2 Ethernet network, not token ring. For more information, see the " Network Cabling and Connectors" section.

13. When analyzing a network trace, a technician notices that there is an unusually large amount of packets originating from a particular MAC address. What could this indicate? A. The device is a printer. B. The device has a malfunctioning NIC card. C. The device is a server. D. The device is using Token-ring.

B. A malfunctioning NIC card will usually broadcast a large amount of packets onto the network. Answer A is incorrect because a printer will not usually send out a large number of network packets. Answer C is incorrect because although a server will generate a lot of network traffic, it should not be anything unusual. Answer D is incorrect because a token ring device would not cause extra network traffic. For more information, see the "Network Analyzers" section.

2. To set up your network monitor for pager remote notification, what additional peripheral will be needed? A. E-mail B. Modem C. Tape drive D. Keyboard

B. A modem will be needed to dial the pager. Answer A is incorrect because e-mail notification will not be able to send data to a pager. Answer C is incorrect because there is no use for a tape drive in a remote alert system. Answer D is incorrect because the monitoring program does not need any type of keyboard input to send alerts to pagers. For more information, see the "Remote Notification" section.

19. A new server has just arrived, which is to be configured as a router. A technician notices that a part is missing from the server. Without it, the server will not perform its proper function. Which of the following is the mostly likely part missing? A. ultra SCSI card B. second Network card C. routing cable D. BNC connector

B. A router server needs at least two network cards to be able to route between two networks. Answer A is incorrect because a SCSI card is not needed for this configuration. Answer C is incorrect because a routing table is a software-based component. Answer D is incorrect because network termination is irrelevant to the routing function. For more information, see the "Installation Strategy" section.

7. A server is being connected to a network switch. What type of network cable will be needed to make the connection? A. Crossover cable B. Straight-through cable C. Rollover cable D. UTP cable

B. A standard straight cable is used to connect a device to a standard network port. Answer A is incorrect because a crossover cable is not needed in this case. Answer C is incorrect because a rollover cable is used for connecting to a device's console port. Answer D is incorrect because it does not specify what type of UTP cable. For more information, see the "Twisted pair" section.

1. CPU stepping refers to what aspect of the processor? A. Level 1 cache B. CPU chip revision number C. Level 2 cache D. Clock speed

B. A step version of a processor is one that contains fixes from the original version. Answer A is incorrect because the Level 1 cache refers to the onboard cache on the CPU. Answer C is incorrect because the Level 2 cache refers to the cache memory that is external to the CPU. Answer D is incorrect because the clock speed refers to the speed at which the CPU executes instructions. For more information, see the "Processor upgrade procedures" section.

7. You purchased a new tape backup hardware device, and just finished the physical mounting of the drive and connecting all the cables. You have installed the proper operating system drivers, and it appears that the system recognizes the device. However, when you install the backup software application (which is used on all the backup servers), it will not recognize the device, even though you used the proper drivers that came with the backup software. What should you have checked before purchasing the unit? A. Vendor's Web site for the latest drivers B. Backup application's hardware compatibly list C. Operating system's hardware compatibly list D. Vendor's Web site for installation guidelines

B. Always check the backup software's hardware compatibility list before purchasing new backup devices. Answer A is incorrect because this would be done after you purchased the unit, and not prior to purchasing it. Answer C is incorrect because while the tape backup hardware may be compatible with the operating system does not mean it will be compatible with the backup software. Answer D is incorrect because it only tells you how to install the device. For more information, see the "Improving backup performance" section.

8. An alert was triggered by the RAID controller telling you that one of the drives is in a rebuild state. What does this mean? A. The RAID controller has removed the drive from the array. B. The RAID controller is rebuilding the drive. C. The RAID controller is formatting the drive. D. The drive is defunct and will not respond to commands

B. An alert that a drive is in a rebuild state typically only means one thing, and that is that the RAID controller is rebuilding the drive. A is incorrect because the drive is being rebuilt, not being removed. C is incorrect because RAID controllers cannot format drives. D is incorrect because if it was defunct, an appropriate alert would have been generated telling you that the drive was defunct. For more information, see the "RAID drive state conditions" section. 9. A logical drive failed to report its presence. What should be done? A. Contact the vendor. B. Correct the problem with the physical drives by reconnecting, replacing, or rebuilding them. C. Count the number of physical drives. D. Let the controller rebuild the logical drive. $$ B. Try to correct the problem with the physical drives by reconnecting, replacing, or rebuilding them. Answer A is incorrect simple because you want to resolve the problem as fast as possible, so you should try to correct the problem yourself first, and then contact the vendor. Answer C should have been done as part of your documentation, and really won't help in this situation. Answer D is incorrect, because the logical drive has failed because several physical drives have failed. For more information, see the "Disk failure" section.

15. After a memory upgrade, a server's OS continues to crash with many application errors. What could be the possible cause of the problem? A. The OS does not support the new RAM. B. One of the new memory chips is defective. C. Parity checking is not enabled on RAM. D. The motherboard does not support the new RAM.

B. Application errors are often caused by defective memory. Other incompatibility problems would result in the system not booting at all. Answer A is incorrect because the memory problem is at the system level, not the OS level. Answer C is incorrect because there is no way to enable parity checking on non-parity type RAM. Answer D is incorrect because if the motherboard did not support the RAM, it would not be recognized by the system. For more information, see the "Installing memory" section.

6. On a Saturday night, a technician's pager goes off, notifying the technician that the file server's OS has crashed, and is in a locked state. The technician dials in to the server's remote access card to troubleshoot the problem. What is the best way to recover the server? A. Come on-site to examine the problem. B. Remotely reboot the server. C. Activate the wake-on-LAN feature. D. Connect to the server's console to reboot the server from the OS.

B. Because the OS is locked up, there is nothing that can be done other than to reset the server, and see if it boots up properly. Answer A is incorrect because there is no need to go on-site if the server can be remotely rebooted. Answer C is incorrect because a server should not be running a wake-on-LAN, which allows a device to be turned on remotely. Answer D is incorrect because the technician will not be able to connect to the server's console if the OS is locked. For more information, see the "Troubleshooting Remotely" section.

4. Near the end of day, you decide it is a good time to upgrade the tape backup device drivers. After doing so, you perform a quick test, but the backup software no longer recognizes the device. You confirm that all cables are secure. What should you do next, keeping in mind that the backup begins in 30 minutes? A. Consult documentation on the vendor's Web site. B. Reinstall the old drivers, and then resolve the issue properly when you have more time. C. Pull out all the connections, including the SCSI card, and clean them. D. Reinstall the operating system.

B. Because you have limited time to troubleshoot, you should reinstall the old drivers, because you know they worked before you installed the new ones. When you have more time, you can consult the vendor's Web site for more information. There should not be a problem with the SCSI card, or the operating system because it everything was functioning correctly with the old drivers. For more information, see the "Drivers" section.

16. When looking up an OS software program on a vendor's technical support knowledgebase on Web, you are asked to download a hot fix file. What should be you next step in troubleshooting the problem? A. Download and install the hot fix file. B. Call the vendor's technical support and verify the hot fix. C. Boot the server with the hot fix boot disk. D. Look up the software error code in the OS manual.

B. Before installing any patch or hot fix, you should verify that the problem resolved by the hot fix is the one you are actually experiencing. Answer A is incorrect because the problem might be something else entirely if you haven't investigated further, and installing the hot fix may damage your system. Answer C is incorrect because the hot fix may be for a problem that is not the same as yours, since it wasn't verified with the vendor. Answer D is incorrect because the most current error information will be on the Web site. For more information, see the "Technical support" section.

5. A user complains she can no longer access a Windows server they were working on all afternoon. What should the administrator do first? A. Hang up the phone. B. Ask the user to recreate the problem. C. Reboot the PC. D. Reinstall Windows.

B. By asking the user to recreate the problem, an administrator can see first hand the problem and what the conditions were that created the problem. Hanging up the phone on the user is rude and may lead to dismissal. Rebooting the PC will not help solve the problem. Reinstalling Windows avoids the issue, and there is no guarantees it will resolve the issue.

11. A user is reporting a strange operating system error on his computer. You are unable to decipher the error message, and it does not appear in the OS manual. What is the next best resource to use to help troubleshoot the problem? A. Check the readme file on the installation disk. B. Enter the error into the vendor's Web knowledgebase. C. Call the vendor's technical support line, which charges $3.99 a minute. D. Check the manual for the computer's motherboard.

B. By entering the error into the vendor's knowledgebase, you should be able to obtain technical documents related to that problem. Answer A is incorrect because the readme will only contain error information current at the time of the original release of the OS. Answer C is incorrect because the answer should be found using the free Web knowledgebase. Answer D is incorrect because the motherboard manual will not aid you with OS software errors. For more information, see the "Web site" section.

6. What aspect of a RAID controller can increase the write performance of an array? A. Parity striping B. RAID caching C. Disk mirroring D. BIOS upgrade

B. Caching on the RAID controller will speed up disk writes. Answer A is incorrect because the calculation of parity, and writing data to multiple drives, slows down disk writes. Answer C is incorrect because a mirrored disk array has to write the same data to a separate disk, which decreases performance. Answer D is incorrect because a BIOS upgrade will not affect write performance. For more information, see the "Hardware RAID and Software RAID" section.

44. Which processor level cache is the fastest? A. L0 B. L1 C. L2 D. L3

B. Currently, there are three level caches installed inside a processor. Of the three, the L1 cache is the fastest. L1 is also the smallest of the three caches. The L3 cache is the slowest, but the largest of the three caches and the L2 cache is in the middle of both speed and capacity.

6. Which type of memory can RAM be? A. EEPROM B. DDR3 C. L1 D. Flash

B. DDR3 is a type of RAM. EEPROM is a type of ROM. L1 is cache memory located in the processor. Flash is a type of solid state memory.

15. You boss asks you how often you should test the DRP plan. How should you respond? A. Every day B. Once per year C. Once a month D. Just before a disaster

B. Disaster recovery testing should be done on a yearly basis. This is mainly because of the length of time it takes to complete the testing, and the cost of performing the testing. For more information, see the "Testing the Disaster Recovery Plan" section.

4. A server that has been installed for a few days is continually freezing up. What is the most likely cause of the problem? A. The power supply fan is not working properly. B. The CPU fan is not sitting on the chip properly. C. The UPS is disconnected. D. The server room has improper ventilation.

B. Erratic server behavior, including freezing, is most often caused by CPU malfunction as a result of overheating. Answer A is incorrect because the fan failing on the power supply will not cause the CPU to overheat, but it may cause the power supply to fail. Answer C is incorrect because disconnecting the UPS will not cause the server to halt. Answer D is incorrect because this may cause the server room to increase in temperature, but would not directly affect the CPU. For more information, see the "Chip fan" section.

1. The Director of Operations wants to know what guidelines he should be looking at when deciding where to put the server room. What is the best answer? A. In a central location near the parking garage for easy entry B. In a central location away from the building exterior, parking garages, or top floor locations C. Near the building exterior, not in a central location D. In a central location, near the building exterior, but away from parking garages and top floor locations

B. For maximum security, the computer room should be located in a central location, away from the building exterior, parking garage, or top floor locations. For more information see the "Server room construction" section.

1. Which of the following is usually not a server room environment issue? A. Temperature B. Server Room door unlocked C. Brownouts D. Power spike

B. Having a server room door unlocked is a security issue, not an environmental issue. Answers A, C, and D are incorrect because these are all important server room environmental issues. For more information see the "Temperature and Ventilation" section.

12. A technician visiting a customer site is trying to fix a failed drive in a RAID array. The customer is shocked when the technician pulls the failed drive out and replaces it while the system is still online and live. How did the technician accomplish this? A. The drive was a hot spare. B. The drive was a hot plug drive. C. It was a RAID 5 array. D. The server was a non-critical server.

B. Hot plug technology enables you to remove and add drives while the system is still powered on and running. Answer A is incorrect because a hot spare does not need to be replaced, it takes over automatically. Answer C is incorrect because the RAID level is not relevant in this case. Answer D is incorrect because you would never pull a non-hot plug hard drive out of a live system, even if it was not critical. For more information, see the "RAID Disk Concepts" section.

15. What best describes HyperThreading? A. It is a management protocol. B. Performs computational tasks in parallel. C. Performs automatic host address configuration. D. It speeds up error reporting services.

B. HyperThreading was introduced by Intel for their Pentium 4 processors. It allowed a single physical processor to act as a multicore processor by processing multiple threads at the same time.

8. Your company is performing a disaster recovery test at an off site agency. The disaster recovery manager wants you to come in to perform a restore of one of the data from one of the servers, and he needs to know how long it will take. The off-site location is costing the company $5,000.00 per day, and they only have two days to complete the test. You tell the manager that it will only take you 2 hours to complete the restore. Unfortunately, when it comes time to do the test it actually took you 6 hours, therefore, preventing the disaster recovery test from completing properly. What should you have done prior to the test? A. Record the time it took to do a full backup and estimate the time for a restore. B. Perform a full restore, or restore a portion of the data to some empty space, and then estimated the restore time based on your results. C. Consult the backup software manuals for restore times. D. Explain to the DRP manager that there is no way of knowing the restore time, and that he should be prepared for anything.

B. If possible, perform a full restore of the data. If this is not possible, restore a subset of the data (2GB) to some empty space on the server. This will give you an idea of how long it would take to restore the rest of the data. Answer A is incorrect because restore processes usually take longer than backups. Answer C is incorrect because the manuals cannot account for your server environment and what data you are restoring. Answer D is incorrect because you can estimate the restore time. For more information, see the "Record it" section.

8. The insurance agency asks you what precautions you are taking to protect the company from a natural disaster. How should you respond? A. Assure them that there are multiple copies of tape backups, and all are kept on-site. B. Assure them that you have a sound backup plan, media is stored at a reputable off-site agency, and backups are verified. C. Assure them that they have nothing to worry about because you have never received a single error when performing tape backups. D. Assure them that you tested your Disaster Recovery Plan two years ago, and updated it immediately after the test.

B. If tapes are not kept off-site then they could be destroyed in the disaster as well. Verifying backup ensures that they are reliable. For more information, see the "Natural disasters" section.

6. Your boss asks you what steps you have taken to ensure you have a sound tape backup system. How should you respond? A. Verify your backups, and purchase a backup unit for the off-site location. B. Verify backups, keep an exact spare tape unit, backups, cables, SCSI adapters and device drives at an off-site location. C. Keep an additional tape backup unit at your on-site location, so that you can recover even faster. D. Rotate the media to an off-site location.

B. If you cannot verify your backups, then you really never know if they are good or not. Keeping cables, SCSI adapters, device drives, and a spare unit will save you a lot of time in the recovery process. Answers A and D are incorrect because you also need to include the other items mentioned in the answer. Answer C is incorrect because if a disaster occurs and destroys your company's location, then this unit will be destroyed as well. For more information, see the "The disaster recovery document" section.

8. A customer is complaining that their server loses its connection with the network from time to time. What is the most likely cause of the problem? A. The OS networking configuration is wrong. B. The network cable is being caught in the server cabinet door. C. The network cable is not plugged into a hub or switch. D. The NIC is only running at 10 MB.

Answer C is incorrect because there would be no connection at all if the cable was unplugged. Answer D is incorrect because the network speed would not create intermittent communications. For more information see the "Network cabling" section. 9. What is the most likely cause of CPU overheating? A. Improper ventilation B. Lack of server room air conditioning C. Faulty power supply fan D. Malfunctioning CPU fan$$ D. A properly functioning CPU fan is integral in keeping the CPU cool. Answer A is incorrect because improper ventilation would heat up the general area around the server, but would not cause the CPU to directly overheat. Answer B is incorrect because a lack of air conditioning would not directly cause the CPU to overheat. Answer C is incorrect because a faulty power supply fan would not cause the CPU to overheat, but it may lead to a power supply failure. For more information, see the "Chip fan" section.

5. What happens when hard disk drive fails in a hardware-implemented RAID 1 system? A. The server crashes and cannot be recovered. B. The system fails over to the mirrored drive. C. Nothing the parity drive takes over from the failed drive. D. The duplexed controller repairs the failed hard drive.

B. In a RAID 1 array using mirroring, the system will fail over to the mirrored drive, which contains an exact replica of the data. Answer A is incorrect because the RAID 1 system is fault-tolerant and will not crash. Answer C is incorrect because there is no parity involved in RAID 1 mirroring. Answer D is incorrect because a duplex controller does not repair a mirrored drive. For more information, see the "RAID Levels" section.

15. A technician is replacing an internal Web server with a new server containing a more powerful CPU and memory. The location of the new server has been verified for proper environmental and power requirements. Which of the following is the next aspect of the server's location to verify before installation? A. UPS size B. network availability C. proxy connections D. firewall rules

B. Network availability is the next most important concern. Answer A is incorrect because the UPS size should be already decided.

For more information, see the "Network Cabling and Connectors" section.

19. A customer wants to upgrade their Pentium 166MHz MMX system with a new Pentium III processor. What can the technician do to complete the upgrade? A. Verify that the new CPU is supported in the BIOS. B. Nothing. The new CPU will not work in an older motherboard. C. Verify the system bus speed. D. Verify the new CPU uses MMX.

B. Newer CPU chips will not fit or work in older motherboards. Answer A is incorrect because the BIOS is not relevant in this case. Answer C is incorrect because the system bus speed is not relevant. Answer D is incorrect because the Pentium III chip is already MMX capable. For more information, see the "Types of CPU sockets" section.

17. A technician is installing a server that uses two ATA-66 drives. The drives came with color-coded 80-conductor cables. What is the color-coding for? A. To signify that they are for use with ATA-66. B. To signify where the master and slave drives should be located on the cable. C. The color is to show where Pin1 on the cable is. D. The colors show where the cable is terminated.

B. Newer cable select systems color-code the connectors on the IDE cable to more easily show where the master and slave drives go. Answer A is incorrect, because the colors do not identify the device type. Answer C is incorrect, because the red stripe along the edge of the cable signifies pin 1. Answer D is incorrect, because there is no termination on an IDE/ATA system. For more information, see the "IDE configuration" section.

88. Which best describes the function of RAID 5? A. Striping. B. Striping with one distributed parity. C. Striping with two distributed parity. D. Striping and mirroring.

B. RAID 5 can be best described as striping with one distributed parity. RAID 0 is striping. RAID 6 is striping with two distributed parity. RAID 0+1 is striping and mirroring.

14. A technician is building a RAID 5 array. The equipment has just arrived, and contains a SCSI RAID controller, four 9GB drives, and SCSI cables. The customer has requested that the disk size be 27GB. Does the technician have enough equipment? A. No, an additional disk controller is need. B. Yes, all the equipment needed has arrived. C. No, an additional 9GB is needed for parity. D. Yes, but only enough for a RAID 3 array.

B. Remember that parity is distributed in RAID 5, but it still takes up the equivalent of one drive. Answer A is incorrect because you only need a second controller when performing disk duplexing. Answer C is incorrect because the disk size requested already takes into account the equivalent of one drive for parity. Answer D is incorrect because a RAID 3 array uses the same amount of hard drives as a RAID 5, except the parity is not distributed across all drives. For more information, see the "RAID Levels" section.

2. A technician is using a KVM switch to access each server in a server rack. On one of the servers, the keyboard and mouse do not seem to be working. What should the technician do first to try to fix the problem? A. Press the right mouse button. B. Reset the KVM switch. C. Reboot the server. D. Press the Escape key on the keyboard.

B. Resetting the KVM switch should restore functionality to the keyboard and mouse. Answer A is incorrect because pressing the right-mouse button will not do anything. Answer C is incorrect because rebooting the server might not initially be necessary. Answer D is incorrect because pressing the Escape key will not help if the keyboard is not functioning. For more information, see the "Installing external devices" section.

5. What are the two current versions of SNMP called? A. SNMPvA and SNMPvB B. SNMPv1 and SNMPv2 C. SNMPv4 and SMPv5 D. SNMPvC and SNMPvD

There are three key components in an SNMP managed network. Based on the list below, which ones are correct? I. Managed devices II. Thresholds III. Agents IV. NMS A. I and IV only B. I, III, and IV only C. I, II, and III only D. II and III only$$ B. Managed devices, agents, and the NMS are the three key components in an SNMP managed network. Thresholds are part of the network, but are configured on the managed devices. For more information, see the "Monitoring the network with SNMP" section.

20. A customer wishes to implement a RAID solution on their server. Because of costs, they wish to use a software-based RAID system. What must be present to implement this system? A. An external RAID storage system B. Enough CPU power and RAM to power the system C. An embedded RAID controller D. Hot swap disk drives

B. Software RAID requires more system resource overhead than a hardware RAID solution. Answer A is incorrect because a software RAID array is implemented by the OS, not by external hardware. Answer C is incorrect because software RAID does not use any type of hardware controller. Answer D is incorrect because hot swap drives will not be used in a software RAID system. For more information, see the "Hardware RAID and Software RAID" section.

12. What is not a component that is typically used for redundancy purposes? A. Hard drives B. Sound cards C. Power supplies D. NICs

B. Sound cards are obviously not a necessity in any server system let alone for redundancy purposes. Answers A, B, and D are incorrect, because all these items are usually used for redundancy. For more information, see the "Planning for Redundancy" section.

11. A technician wants to properly stabilize a server rack. There are currently five servers mounted on the rack. What can be done to make sure the rack will not move or tip over? A. Move the heaviest servers to the top of the rack. B. Add stabilizer plates to all six sides of the rack. C. Add stabilizer plates to the front and back sides of the rack. D. Bolt the rack into the floor.

B. Stabilizer plates can be mounted on all sides of the rack, which prevents it from tipping over. Answer A is incorrect because the heaviest servers should be located on the bottom of the rack. Answer C is incorrect because having stabilizer plates only on the front and back will not prevent the rack from tipping sideways. Answer D is incorrect because bolting the rack to the floor is inefficient and not necessary. For more information, see the "Twisted pair" section.

53. An administrator wants to configure RAID to use striping. He has three hard drives. Two has 200GB and one has 250GB of unallocated space. What will be the size of the stripe set? A. 200 GB B. 450 GB C. 600 GB D. 700 GB

B. Striping is RAID 0. When RAID is used the size used in all hard drives is the size of the smallest capacity drive. In this question, the smallest drives are 200GB. Therefore, in the third drive, only 200GB of the 250GB are used. 3 x 200GB = 600GB.

11. Ideally, where should tape backups be stored for maximum security? A. Fireproof safe B. Off-site agency C. Off-site at administrator's house D. Locked in the server room

B. Tape backups should be kept at an off-site agency because they can provide the best security and protection for your business. These companies ensure that they meet all the environmental requirements necessary for tape storage. Fireproof safes are not very reliable, and it could be weeks before the safe is located. For more information see the "Off-site storage" section.

20. A server is having network performance issues. When the technician checks the lights on the network card, which is a dual-speed 10/100 NIC card, the indicator light is showing that the card is running at 10 Mbps when it should be running at 100 Mbps. What is the most likely cause of the problem? A. The network cable is defective. B. The switch that the server is plugged into is only running at 10 Mbps. C. The server BIOS does not support dual-speed NIC cards. D. The indicator lights are reversed.

B. The Ethernet switch only supports 10 Mbps, which the NIC auto-detected. Answer A is incorrect because the server would not be working at all if the cable was defective. Answer C is incorrect because the BIOS has nothing to do with duplex or speed settings. Answer D is incorrect because the lights are not reversed. For more information, see the "Upgrading Network Interface Cards" section.

2. A server will not boot properly. When it starts up, the server beeps twice and goes no further, without booting into the operating system. A technician is using a POST diagnostic adapter to troubleshoot the error, which seems to be POST related. What is the proper procedure for using a POST diagnostic card? A. Insert the card into an expansion slot, and boot the server using a diagnostic floppy disk. B. Insert the card into an expansion slot, and boot the server. Error codes will display on the POST card. C. Connect the POST device to the server's serial port. Information will be saved to a text file on the hard disk. D. Insert the card into an expansion slot, and note the error codes displayed on the card while the server is turned off.

B. The POST card needs to be plugged into an available expansion slot, and then the server is rebooted. Errors codes will appear on the card's built-in display. Answer A is incorrect because there is no need for a diagnostic boot disk. Answer C is incorrect because a POST card plugs into an available expansion slot. Answer D is incorrect because the server must be turned on for the diagnostic card to read from the POST routine. For more information, see the "POST card" section. 3. A technician is using a vendor-specific hardware diagnostic tool to diagnose a problem with the hard drive subsystem. The tool is reporting an error code, but the technician is unable to find the code in the diagnostic tool's manual. What is the best place to check to find information on the error code? A. Vendor's Web site B. Installation CD-ROM C. E-mail the vendor's technical support D. Diagnostic tool readme file$$ A. The vendor's Web site is the best place to get the most current error codes. Answer B is incorrect because the CD-ROM will only have information current up to the release for the product. Answer C is incorrect because you can find the information more quickly by scanning the vendor's website. Answer D is incorrect because the readme file will only be as current as the release of the product. For more information, see the "Using vendor resources" section.

3. The Level 2 cache on a Pentium Pro system is located on which part of the server system? A. Motherboard B. CPU C. RAM D. Hard disk drive

B. The Pentium Pro system has the Level-2 cache located on the CPU. Other systems have the Level-2 cache located on the motherboard, or a daughterboard. Answer A is incorrect because the Level-2 cache of the Pentium Pro is on the CPU itself. Answer C is incorrect because the cache is not part of the RAM. Answer D is incorrect because Level-2 cache is not located on the hard drive. For more information, see the "CPU architectures" section.

5. One of the drives fails in your stripe set with parity RAID scheme. How will it be recovered? A. The data is restored from tape backup to the replacement drive. B. The RAID system is repopulated when the RAID controller calculates the missing information from the parity reconstruction algorithm. C. Data blocks are copied from the failed drive and copied to the new drive. D. Data blocks are read from the functional drive and copied to the replacement drive.

B. The RAID system is repopulated when the RAID controller calculates the missing information from the parity reconstruction algorithm. Answer A is incorrect because the question refers to rebuilding drives in an array and not restoring from backup. Answer C is incorrect because you cannot copy data from a failed drive. Answer D is incorrect because this describes a mirrored set. For more information, see the "Recovering from a disk failure on a strip set with parity" section.

15. A technician has configured two networks cards as an adaptive team. They have been given two separate IP addresses. When the server networking is started, the adapter teaming does not work properly. What is the most likely cause of the problem? A. The NIC cards are from different vendors. B. The adapter team should have its own single IP address. C. The network cards do not support teaming. D. The NIC cards are set to half-duplex.

B. The adapter team needs to be assigned its own IP address. Answer A is incorrect because it does not matter if the network cards are from different vendors. Answer C is incorrect because any two cards can be teamed together. Answer D is incorrect because the duplex setting does not impact the teaming operation. For more information, see the "Adaptive teaming" section.

2. In SNMP, what does the agent software do? A. Collects data and sends it via e-mail to a predetermined address. B. Collects information and forwards it to an NMS. C. Collects data and forwards the information to a server operating system. D. It simply collects the data, and you must manually seek the information using a NMS.

B. The agent software that is loaded by the devices collects information and forwards the information to a Network Management System (NMS). Answer A is incorrect because the NMS software has e-mail capabilities, not the agent. Answer C is incorrect because the information has to go to an NMS, not the server operating system. Answer D is incorrect because manually seeking the information defeats the purpose of having agents on the devices. For more information, see the "Monitoring the network with SNMP" section.

32. What is the bandwidth of Ultra2 Wide SCSI? A. 40 MBps B. 80 MBps C. 160 MBps D. 320 MBps

Current performance statistics over one day, one week, and one month D. A server baseline, and performance data from the last day of the month

B. The first thing you will need to evaluate performance and compare results will be the server baseline, and the current performance statistics. For more information, see the "Creating a Baseline" section.

76. Which of the following allows for the restoration of the most data? A. System restore point B. Full backup C. Incremental backup D. Differential backup

B. The full backup allows for the restoration of the most data. The system restore point backs up only the system state. The incremental backup only backs up files since the last full or incremental backup. The differential backup backs up files since the last full or incremental backup.

6. A SCSI host adapter came factory-installed with a SCSI ID of 1. What SCSI ID should the technician set the host adapter to? A. 1 B. 7 C. 0 D. 2

B. The host adapter should be set to ID 7 to give it the highest priority on the SCSI bus. Answer A is incorrect because some other device other than the boot device should have this ID. Answer C is incorrect because ID 0 should be used for the boot device on the SCSI bus. Answer D is incorrect because device 2 should belong to another peripheral on the SCSI bus. For more information, see the "Verifying SCSI IDs and Termination" section.

30. An uniterruptible power supply is no longer working. What is most likely the cause? A. The cable is not connected to the computer. B. A new battery is needed. C. The computer is incompatible. D. Windows needs to be reinstalled.

B. The key here is that the UPS is no longer working which implies it used to work. Therefore, it is reasonable to assume the cable is connected to the computer, the computer is compatible, and Windows does not need to be reinstalled. Therefore, the only answer is that a new battery for the UPS may be needed.

63. What is the principle behind ACLs? A. Implicit permit. B. Implicit deny. C. Explicit permit. D. Explicit deny.

B. The main principle behind access control lists is implicit deny. If the information passing through the access control list does not match any of the conditions, access is implicitly denied. This works for permissions and filtering packets.

13. During a server's POST routine, a fault was found in the server's memory. The server still finishes the POST process and boots the network operating system. What should the technician do next? A. Nothing, as the server still boots up. B. The server memory should be replaced. C. The server should be rebooted. D. The BIOS should be flashed, and then the POST should be run again.

B. The memory should be replaced, as it is showing a fault in the POST process. Answer A is incorrect because there is still a problem with the RAM that could affect the network OS performance. Answer C is incorrect because rebooting the server will not fix the problem. Answer D is incorrect because flashing the BIOS will not repair the memory fault. For more information, see the "Monitoring the Power-On Sequence" section.

7. A technician is installing additional memory into a server. The technician did not perform any proper grounding and ESD prevention measures, and during the installation, a static shock visibly came into contact with the memory. When the server is started, the POST reports a parity error with the memory. What should be done to fix the memory problem? A. The memory should be grounded. B. The memory should be replaced. C. The memory should be reinstalled while the technician is wearing an anti-static wrist strap. D. Nothing, the memory is non-parity RAM.

B. The memory was damaged by the static shock and should be replaced. Answer A is incorrect because the memory cannot be fixed once it has been damaged by an electrostatic discharge. Answer C is incorrect because the memory is already damaged, and reinstalling it will not repair it. Answer D is incorrect because the message indicates an error and is not relaying information. For more information, see the "Installing internal devices" section.

22. What is the minimum number of drives in a RAID 5 array? A. 2 B. 3 C. 4 D. 5

B. The minimum number of drives required in a RAID 5 array is 3. Using 2 drives, one cannot configure a RAID 5 array. While it is possible to configure a RAID 5 array with 4 or 5 drives, it is not the minimum number of drives allowed.

39. Which of the following servers can be configured to process user request to access Internet sites while limiting the amount of bandwidth forwarded out the company WAN? A. Web server. B. Proxy server. C. DHCP server. D. File server.

B. The most common use of a proxy server in an organization occurs when clients connect to a web server. Instead of sending the information out to the Internet each time clients want to visit the same website, the website will be cached on the proxy server, and will send the website saved in the cache back to the clients. The use of a proxy server in this manner saves bandwidth and limits the amount of WAN traffic that exits an organization.

2. A technician has replaced a server NIC that was running at full-duplex 10Mbps with a new one that is dual speed 10/100 Mbps. After installation, and successfully loading a new network driver, the card still does not communicate with the network, although the link light is on. What is the most likely cause of the problem? A. The network cable is unplugged. B. The new network card is set for half-duplex. C. The network cable is defective. D. The network isn't configured for dual speed.

B. The new network card should have been set to full duplex mode. Answers A and C are incorrect because the link light would not be on if the cable was unplugged or defective.

38. Which of the following is considered the most important environmental issue in a server room? A. Recycle bin in the server room. B. Unlocked server room. C. Sticky door handle. D. Gum on the floor.

B. The only important environmental issue here is that the server room is unlocked. An unlocked server room is potentially dangerous as it invites possibly theft or damage to the server equipment. The other answers are environmental concerns, but nothing that is as important as an unlocked server room.

12. B. The server does not exist in the DNS table, so the domain name cannot be resolved to the IP address. Answer A is incorrect because a WINS server is used to map NetBIOS names to IP addresses. Answer C is incorrect because the LMHOSTS file is used to map NetBIOS names to IP addresses. Answer D is incorrect because the subnet mask is fine if the technician can ping the IP address. For more information, see the "Configuring and Verifying Network Connectivity" section.

B. The server does not exist in the DNS table, so the domain name cannot be resolved to the IP address. Answer A is incorrect because a WINS server is used to map NetBIOS names to IP addresses. Answer C is incorrect because the LMHOSTS file is used to map NetBIOS names to IP addresses. Answer D is incorrect because the subnet mask is fine if the technician can ping the IP address. For more information, see the "Configuring and Verifying Network Connectivity" section. 13. D. The /etc file system is from a Unix installation. Answer A is incorrect because this should be used for an OS/2 installation. Answer B is incorrect because the Windows ERD disk should be used for an NT server. Answer C is incorrect because the startup.ncf file configures boot options for a NetWare server. For more information, see the "Installing the NOS" section. $$ D. The /etc file system is from a Unix installation. Answer A is incorrect because this should be used for an OS/2 installation. Answer B is incorrect because the Windows ERD disk should be used for an NT server. Answer C is incorrect because the startup.ncf file configures boot options for a NetWare server. For more information, see the "Installing the NOS" section.

5. When a server has finished its POST routine, what is the next step in the server startup sequence? A. The server will check the RAM. B. The server will start the network operating system. C. The NIC card BIOS will be checked. D. The power supply will be checked.

B. The server will start the network operating system once all the POST tests have finished. Answer A is incorrect because the RAM has already been checked during the POST routine. Answer C is incorrect because a NIC does not usually contain a BIOS. Answer D is incorrect because the power supply is checked at the beginning of POST testing. For more information, see the "Monitoring the Power-On Sequence" section.

3. A technician is extending a rack-mounted server that is located near the top of the rack. When the server is fully extended, the rack begins to tip over. What is the most likely cause of the imbalance in the rack? A. The rack is too close to the wall. B. The rack has no stabilizer feet attached C. The server should be located lower on the rack. D. The rack is on wheels.

B. The stabilizer feet will prevent the rack from tipping over when a server is extended. Answer A is incorrect because this will not cause the rack to tip over. Answer C is incorrect because the cause is the lack of stabilizer feet. Heavier equipment should be located lower in the rack, but stabilizers will prevent this if they are located higher. Answer D is incorrect because the wheels alone would not cause the imbalance, but they should be retracted when the rack is not being moved. For more information, see the "Preparing the rack for installation" section.

64. What is the transfer speed of PCI with Bus Width of 32 bit and Frequency of 66 MHz? A. 133 MBps B. 266 MBps C. 400 MBps D. 533 MBps

B. The transfer speed of PCI with Bus Width 32-bit and Frenquency 66 MHz is 266 MBps. The base transfer speed of PCI with Bus Width of 32-bit and Frequency 33 MHz is 133 MBps. For each time Bus Width or Frequency is double, the transfer speed is also doubled. 65. An administrator needs to restrict the traffic leaving the network. How can this best be accomplished? A. VLANs B. VTP C. ACLs D. DHCP$$ C. Access control lists can be used to restrict traffic leaving the network. VLANs can be used to logically segment the network within a physical network, but it cannot restrict traffic leaving the network.

13. A technician has added a SCSI tape drive to a server that already contains four Ultra2 SCSI hard drives. When the system is booted, it does not see the new tape drive, and one of the hard drives is not visible. What is the most likely cause of the problem? A. The tape drive's IRQ is conflicting with another device. B. The tape drive and one of the hard drives have the same SCSI ID. C. The SCSI bus was not terminated properly. D. The tape driver has not been loaded.

B. The two devices are configured with the same SCSI ID, causing the problems. Answer A is incorrect because the SCSI device will not be using an IRQ. Answer C is incorrect because the SCSI bus would not work at all if the termination was improperly configured. Answer D is wrong, as the conflict still exists between the hard drive and the tape drive. Loading a driver would not fix the problem. For more information, see the "Tape Drives" section.

20. A hardware vendor's technical support has sent you a Field Replacement Unit (FRU) for your server's power supply. When you try to install it, you notice that it will not fit into the machine, and the connectors do not match up. What is the most likely cause of the problem? A. You need to consult the power supply's manual to install it properly. B. The wrong FRU part was delivered. C. The vendor sent you a better version of the same power supply. D. The motherboard needs to be replaced to support the power supply.

B. The vendor has sent you the wrong part for your server. Answer A is incorrect because the power supply FRU should be identical to the one you already have. Answer C is incorrect because a FRU is identical to the part that is being replaced. Answer D is incorrect because the FRU should be identical to the original part, and be compatible with the host system. For more information, see the "Replacing Hardware" section.

2. The Disaster Recovery Plan consists of several phases. What are they? A. Risk analysis, Business Impact Analysis, prioritizing recovery requirements, producing the document, testing the plan B. Risk analysis, Business Impact Analysis, prioritizing applications, recovery requirements, producing the document, testing the plan C. Risky business, Cost Impact Assessment, application recovery, analyzing the document, producing the test D. None of the above

B. This is the common methodology, but certainly not the only one. It is vital that you know what information should be included in a disaster recovery document in order to make it affective and useful. For more information, see the "Forming a Disaster Recovery Plan" section.

12. One of the servers in the computer room is switching to battery power at roughly the same time each night, and sometimes randomly through out the week. Before leaving you decide to switch off the lights, and at the same time, you hear the UPS kick in. What should you check? A. Check the building wiring diagrams. B. Turn the light switch back on to see if the wall plug is affected by it. C. Contact the building supervisor. D. Check the wall plug to see if everything is plugged in.

B. This is the quickest and easiest thing to test. If you turn off the lights and the UPS kicks in, then it is likely that the light switch and power receptacle are on the same circuit. Answer A is incorrect because you are probably not familiar with electrical diagrams, and it would take too long to search through them. Answer C is incorrect because the building supervisor will most likely be unable to help. Answer D is incorrect because the server was working before you turned off the lights, so it must have been plugged in. For more information, see the "Checking cabling" section.

7. What are the two criteria that must be met in order for a contaminant to be considered harmful? A. They must have physical properties that could cause damage to equipment, and they must remain stationary. B. They must have physical properties that could cause damage to equipment, and they must have the ability to travel to areas where they can cause damage. C. They must have the ability to travel to areas where they can cause damage, and they must not have any physical properties. D. None of the above.

B. To be considered dangerous contaminants, particles must have physical properties that could cause damage to equipment, and they must have the ability to travel to areas where they can cause damage. For more information, see the "Sources of contaminants" section.

5. To save on network installation costs, a company wants to use the phone system's UTP cabling already installed in the building, for use in a 10MB local area network. What is the minimum category of twisted-pair cabling that should be used to support networking? A. Category 5 B. Category 3 C. Category 1 D. Category 2

B. To support 10MB networking, the cable should be minimum Category 5 UTP cabling. Answer A is incorrect because Category 5 cabling is the minimum for 100MB capacity. Answer C is incorrect because Category 1 cabling is used for phone lines, and is not suitable for networking. Answer D is incorrect because Category 2 cabling can only support speeds of 1MB, and is not suitable for networks. For more information, see the "Network Cabling and Connectors" section.

45. The company backs up data using Full backup on Sunday night at 11pm. On weekdays and Saturday, the company backs up data using Differential backups at 6pm. The server crashes Thursday afternoon. How many backups are required to fully restore the server? A. One B. Two C. Three D. Four

B. Two backups are required to restore the data on the server. The first backup is the full backup made on Sunday night. The next backup is the differential backups made on Tuesday.

14. A RAID system is being upgraded with extra hard drives. The system is hot swap capable, and can automatically configure the drives. What must be done to make the extra hard drive space available to the operating system? A. Nothing, the allocation is automatic. B. The RAID configuration utility must be used to allocate the extra space. C. Logical drives must be created within the operating system. D. The BIOS must be updated to recognize the change.

B. Typically, you have to configure the RAID array to allocate the space to your logical containers. Answer A is incorrect, because you have to configure the extra space. Answer C is incorrect, although it could be a later step in the process. Answer D is incorrect, because the BIOS has nothing to do with the disk space allocation. For more information, see the "Upgrading SCSI RAID Systems" section.

50. When upgrading an internal file server, what is the first thing an administrator should do? A. Call the ISP. B. Notify the users. C. Reboot the server. D. Reinstall the OS.

B. When downtime is required to upgrade a server, the users should be notified as soon as possible. Ideally, the upgrade should be schedule during non-peak hours, however, if that is not possible users need to be notified immediately. Calling the ISP will not help as the ISP does not care about another organization's internal network. Rebooting the server will not help as it would mean a loss of service for users. Reinstalling the OS will not help as it too will mean a loss of service for users.

10. A technician has replaced an older SCSI RAID controller with a new Wide Ultra2 SCSI RAID controller. After the arrays are reconfigured and the operating system is installed, the technician finds that all the server data has been erased. What should have the technician have done to avoid the problem? A. Updated the system's BIOS to recognize the RAID card. B. Backed up the data and restored it after the upgrade. C. Configured RAID 5 striping. D. Updated the server's diagnostic system partition.

B. When reconfiguring a RAID array for a new adapter, all the data on the disks is lost. Answer A is incorrect because the RAID card was already recognized by the system. Answer C is incorrect because the original data will still be lost. Answer D is incorrect because the server diagnostic partition is separate from the server's data. For more information, see the "RAID controllers" section.

6. A technician has taken a decommissioned server and formatted all the hard drives so that they can be repartitioned. When the technician tries to run the vendor's hard drive configuration utility, the program cannot be found. What is the most likely cause of the problem? A. The program is run from a boot floppy disk. B. The system diagnostic partition was erased by the formatting of the hard drives. C. The BIOS needs to be updated. D. The OS has to be installed first.

B. When the hard drives were erased, the system partition was destroyed. Answer A is incorrect because the system partition can be installed from the boot floppy, but not run. Answer C is incorrect because updating the BIOS would not save the partition. Answer D is incorrect because an OS install will not recover the missing partition. For more information, see the "Upgrading Diagnostic Tools and Utilities" section.

85. There is a problem with communication for the SCSI devices connected to the server. What is most likely the problem? A. RAID is not configured correctly. B. Termination is not correct. C. More RAM is needed. D. Too much electromagnetic interference.

B. Whenever there is a problem with communication in a SCSI chain, it usually indicates a problem with termination. An incorrect RAID configuration will not cause a problem with communication in a SCSI chain. Adding more RAM to the server will not improve communication.

20. A customer has complained that there is a lot of heat being generated from a particular server cabinet. What is the most likely cause of the problem? A. Lack of a server room air conditioner B. Lack of circulation within the cabinet C. The CPU fan is not working. D. The server has a large number of hard drives.

B. Without proper air circulation, hot air is trapped within the cabinet or server chassis. Answer A is incorrect because having no air conditioning would cause the entire room to heat up, not just one cabinet. Answer C is incorrect because a malfunctioning CPU fan will only overheat the CPU, not the entire cabinet. Answer D is incorrect because having several hard drives will not increase the temperature of that cabinet noticeably. For more information see the "External ventilation" section.

10. An end-user calls the help desk to report that she cannot get access to her network resources? What would NOT be an appropriate question to ask? A. Do you have access to any network resources? B. What did you do wrong? C. Are there any error messages when you log in? D. When did this problem first occur?

B. You do not want to insult the end-user by blaming them for the problem. Answers A, C, and D are incorrect because these are the type of questions that you should ask the end user. For more information, see the "Ask the right questions" section.

10. How do you load the MONITOR utility in Novell? A. Start➪Sys: B. At the console prompt, type MONITOR. C. At the console prompt, type START MONITOR. D. Choose MONITOR from the Novell Console menu.

B. You just need to type the word MONITOR from the console prompt to start the Novell MONITOR utility. For more information, see the "NetWare MONITOR" section. 11. What is the event log utility used in Windows NT/2000 called? A. Event Viewer B. Log Viewer C. EventReporter D. System Log Viewer$$ A. The event log utility used for viewing the logs is called Event Viewer in Windows NT/2000. It can be accessed by selecting Start ➪ Programs ➪ Administrative Tools. Answers B and D are incorrect because there are no such Windows utilities. Answer C is incorrect because EventReporter is a third-party utility. For more information, see the "Using event logs" section.

11. You have been monitoring the processor utilization over the course of a week and notice that it is consistently above 80%. The IS department is under a tight budget after recent hardware upgrades. What do you need to do in order to prevent the users from noticing a problem? A. Add more RAM. B. Upgrade the processor, and offload processes to another server. C. Purchase another server. D. Upgrade the disk subsystem.

B. You may need to upgrade the processor or offload some processes to relieve the processor bottleneck. Answer A is incorrect because memory is not the issue. Answer C would certainly resolve the problem but is not necessarily the right choice because of budget limitations imposed on the IS department. Answer D is incorrect because the issue is not the disk subsystem. For more information, see the "Memory" section.

1. A new server has just been delivered to the computer room. The warehouse personnel mentions that it sat in the loading dock for over an hour in 32- degree temperatures. What should you do? A. Fire it up immediately. B. Wait for the equipment to reach the server room temperature. C. Point a space heater at the server to warm it up. D. Turn the air conditioner down to cool the room temperature.

B. You should always wait for the computer equipment to reach room temperature before turning it on. Turning the equipment on when it is too cold or hot can cause components to fail if they reach the operating temperature to rapidly. For more information, see the "Temperature" section.

14. When is the best time to take server baseline statistics? A. When the server is behaving erratically B. When the server is functioning normally C. During peak loads D. In the morning when everyone logs on to the system

B. You should always want to perform a baseline operation when the server is performing under normal conditions. All the other answers are incorrect because this would give you false data for your baseline. For more information, see the "Performing a Server Baseline" section. 15. What is an import aspect to cover in the server configuration? A. Network documentation B. Disaster recovery documentation C. Documenting the server configuration D. RAID levels$$ C. Ensuring you have good documentation on your server configurations will make them easier to troubleshoot when problems occur, and easier to recover in the event of a disaster. For more information, see the "Documenting the Configuration" section.

26. Which expansion card is installed for a iSCSI SAN connection? A. MAC B. NIC C. AGP D. TACACS+$$

B. iSCSI can be accessed over TCP/IP, therefore, a NIC card is installed to access a SAN through an iSCSI connection. MAC is the physical address of a NIC card or any devices that access a network. AGP is a graphics expansion port. TACACS+ is a proprietary authentication system.

1. You have been asked to install three servers into a cabinet. You want to provide proper electrical protection and battery backup. What sort of considerations must you keep in mind when selecting electrical protection?

Because a battery backup is needed, a UPS solution is needed, rather than just a surge protector, surge suppressor, or line conditioner. You must calculate how much of a load the three servers will use to come up with a VA rating, and then select a UPS that can protect beyond that rating. The UPS software should be configured for each server's operating system, so that the UPS can shut down the server in the event of a power outage.

2. The two new servers in the Scenario #1 have necessitated an upgrade to the UPS, which currently will not handle the load of the extra servers. A new UPS with sufficient capacity for all the servers has been purchased and is ready to be installed. What steps must be taken to properly install and test the new UPS?

Because the new UPS will handle the load of all of the servers combined, the old one can be removed. Disconnect the serial cables connecting the old UPS to the servers, and remove any special UPS software that was installed on the server's network OS. Before connecting the new UPS, (1) open it up and reconnect the battery connector, which was disabled during shipping. (2) Plug the UPS into a power socket, and let it charge for 8 to 10 hours until it is fully charged. Now you can (3) plug the servers into the new UPS and reconnect the serial cables to all of the servers. Next, you must (4)install and configure UPS software on each server, to set up how it will behave in the event of a power failure. Each server should be set to automatically shut down gracefully if it is running on battery power. Once the servers have been configured, you should now (5) test the UPS. First, pull the UPS power plug from the wall socket, and examine the UPS to make sure it is running on battery power. The UPS should sound an audible alarm to warn you that it is running on battery. Next you should examine the servers to see if auto-shutdown has been initiated after a few minutes.

2. A customer is reporting a problem with their server. A few days before, the CPU was upgraded to a faster processor. They are experiencing frequent lockups and system freezes. What steps would you take to diagnose and fix the problem?

Because the problems only began since the CPU was upgraded, it would be wise to start with checking the CPU. The BIOS should be checked to make sure it is the latest version and able to support the new CPU. The most likely culprit, however, is the CPU fan. If it is not functioning properly, it will quickly overheat, and result in erratic server behavior. Any other CPU related problem would result in the system not functioning at all.

3. A database company is currently planning an enterprise-wide server that will be used heavily for transactional data. The management has requested a fast, fault-tolerant system. What system would you recommend and implement?

Because this is a high-end, transactional database system, read and write I/O performance is a must. A large number of disk drives and strong fault tolerance will also be needed for this enterprise system. If this were a smaller database system, a RAID 0+1 array would be acceptable, but because of its size and the critical nature of the data, a RAID 30 or 50 should be used. 1. A. The default network protocol should be TCP/IP. Answers B and C are incorrect because these are NetWare protocols. Answer D is incorrect because NetBIOS is a non-routable protocol, and is only used for local LANs. For more information, see the "Configuring and Verifying Network Connectivity" section.

1. Because of the number of hard disk crashes in the past, your management would like you to develop a fault tolerant system for your company's file server. Your company's users use a lot of disk space, and your system is currently running four 9GB drives in a RAID 0 array, but there is not much disk space left. What system would you recommend to allow for a large disk size plus a good level of fault tolerance?

Because you are running out of disk space, you will need more drives in this system. To create fault tolerance, you will need to implement either a RAID 3 or RAID 5 solution. Consider six or seven 9GB drives, one of which will be used up for parity. Because the system is a file server, and not a transactional database system, read and write performance isn't a large issue, and the higher performance RAID levels are not needed.

1. A new server has just been delivered to the server room. You have been asked to employ ESD best practices while installing and configuring server components. What steps should you take to ensure that the equipment is not accidentally damaged by electrostatic discharge?

Before unpacking the server, set aside a special work area to start the installation. (1) Use a work bench with proper anti-static padding, or if working from the floor, a special anti-static floor mat can be used. When unpacking the server,(2) leave any extra components in their anti-static bags until the moment you install them. Leaving them out in the open leaves them susceptible to ESD. You should (3) attach an anti-static strap to your wrist, with the other end attached to a grounded source, such as the metal casing on the server, or the metal parts of a server rack. Before handling components, (4) you should touch the grounded source to insure that any ESD built up can be discharged. Handle the components carefully when you take them from their anti-static bags, and hold them by the edges, without touching electronic parts such as the circuit board or processor chips. If any components are to be removed from the server, put them into anti-static bags and store them in a safe place.

67. Which technologies allow the sharing of processor in a safe manner for virtualization? A. VTP B. Virtual Master C. VT D. AMD-V E. Hyper-V

14. C. A Class C address uses the range of 192-223 as the first octet. Answer A is incorrect because this range is for a Class A address. Answer B is incorrect because this range is used for a Class B address. Answer D is incorrect because this address is used for broadcasts. For more information, see the "Configuring and Verifying Network Connectivity" section.

C. A Class C address uses the range of 192-223 as the first octet. Answer A is incorrect because this range is for a Class A address. Answer B is incorrect because this range is used for a Class B address. Answer D is incorrect because this address is used for broadcasts. For more information, see the "Configuring and Verifying Network Connectivity" section.

2. What is meant by a baseline? A. How the system runs when under heavy load. B. A compilation of the basic software and drivers needed to make the system run. C. The typical activity of your servers when functioning normally. D. The typical activity of your server during the company's non-working hours.

C. A baseline defines the typical activity of your servers when functioning normally. Answer A is incorrect because you do not want to perform a baseline if the server is under an unusually heavy load. Answer B is incorrect for obvious reasons. Answer D is incorrect because it is the exact opposite of what a baseline is meant to record. You want to create a baseline when typical activity is occurring. For more information, see the "Creating a Baseline" section.

You have confirmed that you are upgrading to the correct version. B. You have printed the documentation and read it thoroughly. C. You have confirmed that the system requirements are met for the agent. D. You have removed all the SNMP traps prior to upgrading.

C. You should make sure that the current version of your operating system is compatible with the latest version of the third-party monitoring system. You may find out that it is intended for the most recent release of your server operating system, or you may be required to have a certain service pack or hot fix installed. Answer A is incorrect because you should ensure that you are not going to upgrade to the wrong version. Answer B is incorrect because this is not a condition that needs to be met before installing the upgrade. This is something that you should do prior to actually installing the original software. Answer D is incorrect because removing all the SNMP traps will only cause you more work as you will have to recreate them. There is no need to remove the traps. For more information, see the "Using monitoring tools" section.

3. Users are complaining that the network performance degrades severely in the evening shift between 11:00 p.m. and 1:30 a.m. You suspect that the problem is caused by the backup job that is running during this time frame, but the baseline performance did not show any problems when you took it several months ago.

Configure the drive as a master on the primary IDE controller. D. Configure the drive as a slave on the primary IDE controller.

D. The new hard drive can be the second device on the primary controller. Answer A is incorrect, because there is room for one more device on each controller. Answer B is incorrect, because you should not connect a CD-ROM with your hard drive, and it is not using cable select. Answer C is incorrect, because the original hard drive is already configured as the master. For more information, see the "IDE configuration" section.

48. The backup application running on the server reports an error. What is the most likely cause? A. The application is not working. B. The network is down. C. Incremental backup was selected instead of differential backup. D. The backup tape is damaged.

D. The only possible answer is that the backup tape is damaged. Since the application is running on the server, the application is working. The network being down has no bearing on the status of the backup application. Selecting the incorrect backup method does not cause the backup application to report an error.

19. A customer is running a RAID 1 array with disk duplexing, and the primary RAID controller has failed. What happens to the system? A. The controller is rebuilt using parity information. B. The controller is swapped with a hot spare RAID controller. C. The system immediately fails. D. Nothing, the mirrored array becomes active using the secondary RAID controller to service the disk drives.

D. The second disk controller will continue to operate the array if the other controller fails. This removes a single disk controller as a point of failure. Answer A is incorrect because a controller cannot be rebuilt. Answer B is incorrect because only a hard drive can be a hot spare. Answer C is incorrect because the system is duplexed, so the system will not fail, and the secondary controller will take over. For more information, see the "RAID Levels" section.

7. A technician is testing a UPS on a new server. When power is disconnected from the UPS, the server runs from the UPS battery for approximately 15 minutes, and then the server is abruptly shut down. The UPS was configured to shut down the server automatically when power is disconnected. What is the most likely cause of the problem? A. The UPS software is not configured properly. B. The parallel cable between the UPS and the server is missing. C. The UPS battery has not been properly charged. D. The serial cable between the server and the UPS is missing.

D. The serial cable connecting the UPS to the server was not connected. Without it, there is no way for the UPS to communicate with the server. Answer A is incorrect because the server software was configured correctly. Answer B is incorrect because a serial cable is used for the connection, not a parallel cable. Answer C is incorrect because the battery operated normally when the power failed. For more information, see the "Verifying Power Sources and UPS Installation" section.

3. D. The server must have enough disk space to install the support pack. Answer A is incorrect because a support pack does not have to be the most recent version to be successfully installed. Answer B is incorrect because the installation will not halt if a backup is not made of files to be replaced. Answer C is incorrect because a Support Pack would not produce this error message. For more information, see the "Applying Patches and Service Packs" section.

D. The server must have enough disk space to install the support pack. Answer A is incorrect because a support pack does not have to be the most recent version to be successfully installed. Answer B is incorrect because the installation will not halt if a backup is not made of files to be replaced. Answer C is incorrect because a Support Pack would not produce this error message. For more information, see the "Applying Patches and Service Packs" section.

3. A customer has a server setup with two NIC cards set for adaptive fault tolerance. A network switch failure causes the server to lose its connection to the network. Why did the fault-tolerant configuration not work? A. The network cards have the same IRQ. B. The network cards were configured with the same IP address. C. You need at least four NIC cards for adaptive fault tolerance. D. The two network cards were plugged into the same Ethernet switch.

D. The switch is a point of failure. The second card should have been plugged into a different switch. Answer A is incorrect because the cards would not have worked at all if they IRQ was the same. Answer B is incorrect because an adapter team should be configured with the same IP address. Answer C is incorrect because you only need a minimum of two cards for adaptive fault tolerance. For more information, see the "Adaptive teaming" section.

43. What three basic components are in the SNMP model?

D. The three basic components in the SNMP model are the Network Management System, managed devices, and agents (usually software based). SNMP also uses UDP to send its messages, but that is not a component.

55. Which expansion slot has the highest bandwidth? A. PCI B. AGP C. ISA D. PCI-e x16

D. The transfer speed of PCI-e x16, assuming version 1.x, is 4000 MBps. The maximum PCI transfer speed is 533 MBps. The maximum transfer speed of AGP is 2133 MBps. The transfer speed of ISA does not compare to PCI, AGP or PCI-e.

10. A server's POST routine halts half-way through the memory check. What is the most likely cause of the problem? A. Only one of the memory modules is bad. B. The server BIOS does not recognize the memory. C. The keyboard is not connected. D. One or both memory modules are bad.

D. This indicates there is a problem with some or all of the RAM modules. Answer A is incorrect because there could be more than one failed memory module. Answer B is incorrect because the memory check had already started, indicating that the memory was recognized by the server. Answer C is incorrect because the POST routine failed during the memory check stage and did not indicate a keyboard error. For more information, see the "Monitoring the Power-On Sequence" section.

13. Your tape backup software can no longer detect the backup hardware. What should you do first? A. Reinstall the backup software. B. Reinstall the tape backup device drivers. C. Take off the case and make sure the SCSI card is inserted properly. D. Check the peripheral cable at both ends to make sure it is securely attached to the server and the tape backup hardware.

D. This is the quickest and easiest thing to do, so you should do it first. Loose connections are a leading cause of many hardware and software problems. Answer A is incorrect because it would be time consuming you could try this after testing other things. Answer B is incorrect because it is not the first step to take. Reinstall the drivers if you think they might be corrupt, or someone updated them. Answer C is also incorrect because this is something that is typically done last. For more information, see the "Examining peripherals" section.

93. After upgrading a driver for a hard drive in Windows, the server does not boot into the OS. Which of the following is the best way to resolve the issue? A. Reinstall Windows. B. Remove the hard drive. C. Restore the latest backup. D. Boot the server, press F8 and select Last Known Good Configuration.

D. To resolve the issue, boot the server, press F8 and select Last Known Good Configuration. The computer will load the last configuration that booted successfully before the driver update.

4. Users report a server cannot be found on the network. What should be done first in a bottom-up troubleshooting approach? A. Update the server OS. B. Escalate the problem. C. Call the ISP. D. Ensure the correct cables are used.

D. Using the bottom up approach, the first stage is to check everything that is related to the physical layer of the OSI model. Ensuring the correct cables are used is the only troubleshooting step that is done in the physical layer.

12. A server has just been connected to a new UPS. When the technician pulls the power plug to test the UPS, both the UPS and the server abruptly shut down. What is the most likely cause of the UPS not running from battery? A. The server BIOS was not updated. B. The UPS software was not installed. C. The serial cable to the server was disconnected. D. The UPS internal battery cable was not connected.

D. When a UPS is first installed, its internal battery must be connected. It is disconnected for shipping safety reasons. Answer A is incorrect because the server BIOS is irrelevant in this issue. Answer B is incorrect because the issue was with the UPS battery. Answer C is incorrect because the serial cable would not have prevented the battery problem. For more information, see the "Charging the UPS battery" section.

4. The administrator is worried that the company's mission-critical server may be experiencing hardware problems. The technician is asked to take precautionary measures, while keeping costs in mind. The technician should: A. Buy a redundant server. B. Install a dedicated hardware monitoring device. C. Configure remote notification. D. Install software-based hardware monitoring agents.

D. While other solutions are expensive, simply installing software-based monitoring tools can be a cost-effective way to implement hardware monitoring. Answer A is incorrect because adding a redundant server is very expensive. Answer B is incorrect because dedicated hardware monitoring devices are costly. Answer C is incorrect because you will need to set up some type of monitoring tool to monitor the hardware, and then configure it for remote notification in the event of an error condition. For more information, see the "Software monitoring of server hardware" section.

4. A technician is installing a network operating system on a multiprocessor server. What should be verified before installing the OS? A. The OS uses a Level 1 or Level 2 cache. B. The OS supports CPU stepping. C. The bus speed of the processor is supported. D. The OS supports multiprocessors.

D. Without OS support, the additional CPU will not be used. Answer A is incorrect because the type of cache is not relevant. Answer B is incorrect because stepping refers to the revision number of the CPU itself, and is independent of the operating system. Answer C is incorrect because the bus speed is not relevant. For more information, see the "Multiprocessing" section.

14. A technician discovers that his pager has stopped receiving remote alerts from a server. What would most likely be the problem? A. SNMP is misconfigured. B. The MIB is corrupted. C. The event logs are turned off. D. The server modem has been disconnected.

D. Without the modem, the server cannot dial the pager to send the alert messages. Answer A is incorrect because this would not stop the pager from receiving remote alerts. Answer B is incorrect because although MIB corruption would only affect a certain device, it would not disable remote notification. Answer C is incorrect because disabling the event logs would only affect local logs on the server, it would not affect remote notification. For more information, see the "Remote Notification" section.

9. Where should backup tapes be kept when in the office? A. In the janitor's closet B. On your desk where you can see them C. In your desk drawer D. In the secure computer room

D. You obviously do not want to keep your tapes in the janitor's closest, but it is also not a good idea to leave them on your desk or in your desk drawer you could be distracted for just a second, and the tapes could be stolen. Tape backups should always be kept in a locked cabinet, or room. Ideally the server room should be used for this purpose. For more information see the "Securing Backup Tapes" section.

6. The IS manager has purchased a new Web server and wants you to set it up in a spare office cubicle. What is the primary concern? A. Desk space B. Proper voltage C. Temperature D. Proper physical security

D. You should be primarily concerned with the physical security of the unit, because you will be unable to lock it in a secured room. For more information see the "Server room access" section.

9. D. ipconfig /all will display all networking information for all network cards. Answers A and B are incorrect because these ipconfig commands are used to release and renew DHCP leases, not view DHCP information. Answer C is incorrect because ifconfig is used for configuring networking on a Unix machine. For more information, see the "Configuring and Verifying Network Connectivity" section.

D. ipconfig /all will display all networking information for all network cards. Answers A and B are incorrect because these ipconfig commands are used to release and renew DHCP leases, not view DHCP information. Answer C is incorrect because ifconfig is used for configuring networking on a Unix machine. For more information, see the "Configuring and Verifying Network Connectivity" section.

2. You get a call from the operations manager telling you that there has been a fire in the building, and everything appears to have been destroyed. You are sick with the idea of how much work it is going to be to get the company back in shape, but you are confident that your disaster recovery plan will enable you to get the computer systems back up and running in a short period of time. What steps should you have taken regarding your backup plan?

Document the hardware and software environments. Maintain a database of all the devices and software programs being backed up. Use off-Site media rotation for weekly and monthly data. Maintain backup and recovery documentation from the testing you performed. Clearly label all the media both physically and electronically to ensure that you can restore the system to its most recent state. Store the nightly backups in a safe location such as your house.

4. What factors should be considered regarding an air conditioning system? Choose all that apply. A. Continuous operation for 24 hours and 365 days per year B. Independent of other systems in the building C. Accommodate expansion D. Allow outside air in to the room to accommodate human occupants, and to maintain positive pressurization E. All of the above

E. Air conditioning systems should be able to meet all of these requirements in order to ensure adequate cooling in the computer room, and adequate safety for occupants and equipment. For more information, see the "Air conditioning" section.

11. What are some symptoms that your systems may have been affected by a virus? A. System is slower. B. Unusual messages keep displaying. C. Files are missing or corrupt. D. Disk space decreases rapidly. E. All of the above

E. All of these are symptoms that a virus may have infected your computer system. For more information, see the "Viruses" section.

4. What are some typical SNMP thresholds? A. Port malfunctions B. Network congestion C. Packet collisions D. Device failures E. All of the above

E. All of these items are typical SNMP thresholds that traps can be set for. For more information, see the "Monitoring the network with SNMP" section

8. Your boss wants to know the advantages of using a key card system for access to the computer room? What are some advantages? A. Individual cards for each person B. Ability to issue temporary cards C. Ability to track who enters the room and when D. Ability to deactivate users permanently, or during certain hours of the day E. All of the above

E. Key cards are one of the best choices for entry systems. They give you the ability to track user access, assign temporary cards, assign time restrictions, and assign individual cards for each user needing access to the computer room. For more information see the "Locks" section.

2. A manager has asked you to take a look at an older server that has not been working for a long time. Because the department's budget has been cut, the manager cannot buy a new server to perform some simple reporting tasks, and would like to get the old server working. The server hangs on the POST routine, but there is no error message except for a single beep. What steps can you take to fix the server?

If the single beep in the POST routine does not properly identify the problem, even after checking the server manual for POST error messages, you should try booting the server with a POST diagnostic card. Install the card into an available expansion slot, and reboot the server. The POST card will give more detailed error messages that you can examine in more detail by using the diagnostic utility's manual. Once you have identified the failed hardware component, you will need to call the server manufacturer to see if they can get you a replacement. Because the server is fairly old, this might not be possible, and other upgrades may be necessary. If you give the vendor's support staff the serial number of the component, they will be able to track it down more easily. Since the server is probably not under warranty anymore, you should give the server serial number to the vendor to verify this. If not, you will have to get the manager to authorize payment for the replacement part.

2. An article came across the president's desk about how server equipment and network devices can cause problems on a network without the administrator being aware. What solution(s) can you propose?

Obviously, the management is worried that there could be server problems when the administrator is off-duty or away from the equipment. The first thing you should do is implement a proper monitoring system such as SNMP, or a third-party monitoring program if the software that came with your server will not perform the tasks you need Next, you can set thresholds on system parameters that you would like to be alerted to. For example, you may want to receive an alert when CPU usage is too high, or if any hardware has failed. These alerts can appear on the console, or through e-mail. To ensure that you receive these alerts during off-hours, you must set up remote notification so that the monitoring program will dial your pager with any alerts. That way, they can be dealt with before your users come in to use the system

1. The company is planning to construct a new building to accommodate current and future growth. The entire company will relocate to this new building and the current one will be sold. As the systems administrator you are asked to define specific requirements for the computer room. What are the major requirements for the new server room?

Server rooms should be located in a central building location away from the building exterior, parking garages, or top floor locations. The server room should be windowless, lockable, with an access control system that provides some sort of an audit trail of who was last in the room. The server room should not be easily visible, and should be constructed with a full-height wall and a fireproof ceiling. There should no more than two doorways, and they should be solid and fireproof. Motion detectors should be considered as part of the design for the computer room. There should not be any windows in the computer room, but if there are, they should be small, barred, locked, and alarmed.

3. A UPS is being connected to a rack containing up to four servers. What considerations must be made when purchasing and installing the UPS?

The VA rating of the servers and other equipment that will be connected to the UPS should be calculated, so that the right size of UPS can be purchased. The UPS should come with enough serial cables to be able to attach to all four servers. The network OS of the servers should be configured to automatically shut down in case of a power failure. The UPS should then have its battery fully charged, and then tested to make sure that the battery will take over when power is disconnected, and that the auto-shutdown of the servers works properly

3. A customer has asked that a new database server be installed using a SCSI hard drive system, and it must support fault tolerance. What kind of recommendations can you make for the installation?

The best solution would be a server that contains a built-in RAID controller and SCA hard drive connections. This allows a fault tolerant RAID system using multiple hard drives to be created, with the ability to use hot plug/hot swap capabilities in the event of a single drive failure. There should also be enough hard drive slots to provide for future expansion.

1. You're employed by a medium-sized manufacturing facility that has several servers and network nodes. Through analysis, you have determined that a total of 8GB needs to be backed up. However, the organization has three shifts running six days per week. Your ability to restore the data is obviously crucial but you only have a small window on Sunday in which to a full backup, and a few hours each weeknight to do the rest of the backups. Three to four weeks of backup history is acceptable. You are told that you are to use the father, son media rotation method. Why might you opt for an eight-tape rotation schedule?

The eight-tape father-son rotation schedule gives you the three to four weeks of backup history, while enabling you to effectively back up all the required data. You will use a differential or incremental backup for the Monday through Thursday media. Four media will be used for the Friday full backups, and they will be rotated and stored off-site. During week one, media 1 through 5 are used. Week two will see the usage of media 1 through 4, and media 6 for the full backup. This continues until media number eight is used.

1. A customer wants to upgrade their server. It is currently running a dual multiprocessor Pentium Pro system with 256MB of RAM. They want to upgrade the processors to Pentium IIIs, and double the RAM to 512MB. As a technician, what steps would you take to verify that your upgrades will work with the current system?

The first problem with the customer's request is that their motherboard won't support a simple replacement of the CPUs with Pentium IIIs. The Pentium Pro motherboard has special sockets for the larger Pentium Pro CPUs, which contain an on-board Level-2 cache. The entire system board would have to be replaced. The technician would have to inspect the current memory configuration to find out what memory it is currently using, and how many empty slots or banks it has. If it is using DIMM slots, and currently has two 128MB DIMMs, there is only one slot left in which a 256MB DIMM can be installed to bring the memory total to 512MB. If the server is using older SIMM technology, it might have four slots of 64MB, which would be full and no more can be added. Considering the motherboard is probably going to be replaced, the SIMM's would all probably have to be replaced anyway. Any upgrade should require an update of the system BIOS, to make sure any new components are recognized when they are installed.

2. A customer is worried about environmental issues in their server room. What aspects of the server room can you examine to ensure a proper environment?

The most important environmental concern in any server room is temperature. An air conditioning system is integral in keeping the server room operating at a constant, cool temperature. You should also make sure that the room is cabled properly, without any cables cluttering the floor, or in any place where they can be easily damaged. Each server should be connected to a UPS, to ensure that the power reaching the machines is consistent, with protection for any voltage surges, spikes, or brownouts. The UPS battery should be powerful enough to allow the servers to be brought down gracefully in the event of a power outage. Examine all the fans operating in the servers to see if they are functioning properly to prevent overheating. Replace any failed units immediately.

3. A technician needs to create a crossover cable to connect two servers together through their network ports. Which wires of a standard UTP cable need to be crossed over to make the cable?

The pin out requirements for a crossover cable are detailed in Figure 2-4. Wires 1 and 3 are crossed over, as are wires 2 and 6. Wires 4, 5, 7, and 8 stay the same.

2. Three new servers are being installed into a new server room. What aspects of the server room should be verified before installing the new equipment?

The server room should contain adequate air conditioning and ventilation. The power source should be verified to ensure good quality power, and that there are enough outlets to handle the amount of equipment. Network connectivity will have to be verified, including cabling location and cable types.

1. A technician is expanding a 10BaseT LAN by adding two new servers: a mail server and a file server. There is only one unused standard port on the current 24-port server room hub, so a new 24-port hub has been purchased to be added on to the first hub. The new hub does not have an uplink port. How many UTP cables will be needed to connect all of the new devices, and what type of cables should they be?

The technician should make three cables, two straight-through cables, and one crossover cable. The straight-through cables are to connect the two servers to the new hub. The crossover cable will be used to connect the two hubs together using a standard network port. A crossover is needed, as the transmit and receive wires on the hub ports are already reversed.

1. A technician is installing a new server, consisting of two ATA-33 hard drives and a CD-ROM drive. The server has a primary and secondary IDE controller. What is the best configuration for the devices?

The two hard drives should be kept together on the same IDE controller. Mixing them with a slower device such as the CD-ROM might cause performance issues. The first hard drive should be configured as the master, and the second hard drive configured as the slave. Alternatively, you can use the cable select on both drives if you have a compatible cable and install the hard drives on the proper connectors. The CD-ROM can be installed as a master on the secondary IDE channel. 2. A technician has just put together a Wide Ultra2 SCSI system consisting of a host adapter, an internal SCSI tape drive, and 4 Wide Ultra2 hard drives. When powered on, the server will not boot properly. The system bus cabling is currently this configuration: Host adapter → hard drive 1 → hard drive 2 → terminator → hard drive 3 → hard drive 4 → hard drive 5 → tape drive Why does the system not boot, and how can it be fixed? $$ The terminator after hard drive 2 is disrupting the bus. Termination should only be at the ends of the SCSI bus. In this case, the host adapter probably has built-in termination, so the middle terminator can be removed and placed at the end of the bus after the tape drive.

1. You are using Windows NT server in you computer environment. Your users are complaining of latency issues on the network. What software tool that comes with NT could you use, and how would you use it effectively?

Under Windows NT you would use Performance Monitor to analyze your server environment. You could make use of the Chart mode by selecting the proper objects and adding the appropriate counters for real time monitoring. Some of these counters are found under the Network Segment and Network Interface objects. They could include: % Broadcast Frames, % Multicast Frames, % Network Utilization, Packets/sec, and Packets Sent/sec. You would use the Log mode to do some extensive logging over the course of the day, week, and so on. At the end of each day you could export the log files and exam them. You would also configure the Alert mode to notify you automatically if any of the thresholds that you set on the object counters were met. You may want to set thresholds on the %Network Utilization, because this counter should not be consistently higher than 50%.

2. A server is exhibiting various problems during its startup routine. The POST tests result in errors at various stages of the routine. What are the stages of the POST process, and what components are checked at each stage?

When a server is first turned on, the (1) power supplies initialize, and as soon as they are ready, they begin to feed power to the system. The CPU and the RAM will be empty, and (2) information is first read from the BIOS ROM. The (3) BIOS initializes and begins testing internal components. System timers, resource identifiers such as IRQ and DMA, cache, CPU, RAM, are all examples of components that are tested at this time. Then, (4) external devices are tested, such as storage systems and SCSI buses, sometimes by their own BIOS if one exists. At this time (5) hard drives and RAID arrays are verified and initialized. When this is complete, the (6) server looks for the first boot device, where the network operating system boot loader resides, which then takes over the boot process of the OS.

1. Management wants you to come up with the best possible solution for a fire prevention system to protect the mission-critical systems in the computer room. What would you recommend?

You need to ensure that you have adequate fire protection by incorporating a manual means of fire suppression in the server room, installing fire extinguishers at strategic locations throughout the room, and using a sprinkler system. Ideally, you should incorporate a dual sprinkler system that makes use of a pre-action water sprinkler system, and gas based sprinkler system using FM 200. This scenario offers the best protection because fire extinguishers and manual suppression equipment will help to control flare-ups while occupants are in the room to control it. The gas system should extinguish the blaze without damaging the hardware. As a last resort, the pre-action water based sprinkler system would run continuously until the fire was extinguished, although it would most likely damage the hardware. However, if it came to that, you would still be able to operate because your tape backups would have been safely stored off-site.

2. A Windows network is being configured to support TCP/IP, because several Unix workstations and servers have been added to the network. What new services must you add to the network to enable both the Windows and Unix machines to connect to the network and connect to each other?

You need to install a DNS server and WINS server on the network. The DNS server will keep a table mapping domain names to IP addresses, so that Unix machines on the network can be referred to by their name rather than an IP address. The WINS server will map Windows NetBIOS names to IP addresses to enable Windows machines to be referred to by their names rather than IP addresses.

1. There is a fire in the computer room that destroys almost all of the equipment in it. What steps should be taken as part of the Disaster Recovery Plan.

You should first and foremost call the fire department, and make sure the building is evacuated. After the fire has been extinguished, you will have to assess the damage and notify the disaster recovery team to but the plan into action. As the team leader, it will be your responsibility to notify all personnel, including management. Each member should have a copy of the disaster recovery plan document, so reiterating the information should not be necessary. You will need to follow the document step by step ensuring that each phase is completed, such as contacting the hot or cold site location, notifying the off-site storage company and getting them to deliver the tapes, and so on. This is a huge process, and you do not want to make any mistakes, so proceed with caution and diligence.

1. A client calls you because he is concerned that his NT SQL Server system was operating slowly. He wants an accurate explanation of why this happened suddenly and why it is not performing as well as before. What steps would you need to have taken prior to this, and what performance counters should you measure?

You should have made a baseline prior to this incident, probably when the server was first installed. You should have included the standard memory, processor, logical disk, and network objects, such as % Processor Time, Pages/sec, Avg. Disk Queue Length, and % Network Utilization. These values represent the system under normal working conditions. Now you can take a new baseline, with the same counters, and compare it against the old baseline. This should help you determine what the problem is. Perhaps the network counter is grossly high, or perhaps processor time is consistently near 100 percent, indicating a need for a new or additional processor. In any event, performing the baseline ahead of time will give you the starting point you need to determine the current problem.

1. A critical database server has suffered a hardware failure. What steps should you take to troubleshoot the problem, keeping in mind that the amount of downtime has to be kept to a minimum?

You should reboot the server, so that you can check the POST routine or vendor hardware diagnostic utility for any errors. If you receive an error, check the server's manual to decipher the error code, to identify the failed hardware. Once you have verified this information, or if you cannot troubleshoot any further, call the hardware vendor's phone support immediately, to help get the problem fixed while minimizing downtime. Depending on the type of maintenance agreement or level of support you have with the vendor, they will either send you a FRU, which will replace your failed component, or they will send a technician to do the replacement. Depending on your level of support, you will have a replacement part within a few hours or longer, but there is no faster way of getting the problem fixed.

1. A customer needs a server solution so that they can serve Web pages, and host an FTP site for the external world, while securing their internal LAN from any outside intrusion. For security purposes, the Web server and FTP services must be installed on their own separate machines. How many servers will be needed, and for what roles should they be configured?

You will need three servers to set up the required environment. To provide Web and FTP services, a server will be needed to perform each function. To secure the internal LAN from the outside world, a firewall server will have to be set up. To fully secure the internal LAN, a DMZ network should be set up, to separate the Web and FTP server on their own LAN. The firewall should have three network cards, one to connect to the outside world, one to connect to the DMZ, and one connected to the internal LAN.

2. A customer has called to say that one of their hard disks has a red light flashing on it, but the system is still functional and running smoothly. When you visit the customer site, what would be your series of steps to troubleshoot and fix the problem?

Your first step in troubleshooting this system is to find out what RAID level it is running. Because the system did not crash, it has some level of fault tolerance. Typically, if there are only two drives in the system, it is a RAID 1 mirroring system. Any system with three drives or more is using a striped RAID system with parity. In either case, if there is no hot spare drive present, all you would have to do is replace the failed disk drive with a new one. If a hot plug system is being used, this can be done while the system is alive and online.

1. You have just installed a new Web server. Your manager is worried about whether the hardware that was purchased will be able to handle the large loads they expect. What steps should you take in monitoring your new server?

Your first step would be to create a baseline of your current performance. Only until you know at what levels your current system is operating can you measure any changes in performance at a later time. Your next step is to monitor your server's performance over a period of time, for example, a seven-day period. When you have the results, you must analyze the data for any changes in performance, especially at different times of the day. Are your backups or scheduled maintenance jobs interfering with performance? Finally, if there any issues such as CPU utilization, RAM, or disk performance issues, you must plan for an upgrade of that component depending on the data you have analyzed.
