Which partition type identifies the partition as one that holds the boot loader program used to start the operating system?

Active Explanation The active partition identifies which partition holds the boot loader code. When the system starts, it looks in the volume boot record (VBR) of the active partition to identify the location of the boot loader code. The system partition is the partition that holds the operating system files. This might be the same as the active partition, but can be different. A primary partition is a partition type on a basic disk. An active partition must be a primary partition, but there can be additional non-active primary partitions on a disk. An extended partition is a partition type that is subdivided into logical drives. The extended partition cannot be the active partition.

If you want to boot from a hard drive, what must it have?

Active partition Explanation The active partition contains the boot sector, which is required to load an operating system. An extended partition is a partition type on a basic disk. An extended partition can exist, but is not required to boot.

Which type of configuration would you use if you wanted to deploy 802.11n technology to communicate directly between two computers using a wireless connection?

Ad hoc

You have a computer with an onboard LAN adapter. The LAN adapter has failed, and you are unable to connect the computer to the network. What should you do?

Add a network card using a PCI slot Explanation In this case, you should install a network adapter in a PCI slot. Your computer would then use the new network adapter instead of the one integrated on the motherboard. While installing the new card, you should disable the onboard LAN adapter to prevent it from showing in Device Manager. Replacing the motherboard is too expensive when compared to installing a new expansion card. AGP slots are used for video cards, not network cards. Clearing the CMOS settings erases the configuration information, but does not fix the LAN adapter that is not functioning.

You have just received a frantic call from a customer. She informs you that after turning her computer on, she received the following error: The SMART hard disk check has detected an imminent failure. Which of the following is the BEST first step to take?

Back up all important data and files. Explanation Self-Monitoring, Analysis, and Reporting Technology (SMART) is a monitoring system that detects drive errors. If SMART detects enough errors that a complete hard disk failure is imminent, a warning is displayed when the system boots. Self-monitoring is designed to warn you of disk failures before they actually happen. Therefore, if you see a SMART error, you should immediately back up the data on the disk and then, to be safe, replace the drive. Running a hard drive test to verify the condition of the hard disk is a good second step to verify the that the SMART error is accurate. A defragmentation tool will not help you troubleshoot or fix disk errors. Its main purpose is to consolidate files to create disk space and improve computer disk reads.

You have a computer with a removable disk drive that has been formatted with NTFS. You want the drive to use FAT32 to be compatible with more operating systems. The drive is currently configured using drive letter D:. Which of the following actions MUST you complete to make the desired changes?

Back up the data on the D: drive. Reformat the D: drive using FAT32. Restore the data. Explanation The only way to go from NTFS to FAT32 is to reformat the drive. Because reformatting destroys all data, you should back up the drive before formatting and then restore the data after formatting the drive.

One day, while trying to start your Windows 10 system, you see the following error displayed: Could not read from the selected boot disk. Check boot path and disk hardware. Which of the following will MOST likely fix the problem?

Boot into the recovery environment and run the bootrec /rebuildbcd command. Explanation This error message is generated when the system cannot find the partition specified in the BCD database where the operating system files are located. For example, the database might be pointing to the C: drive for the operating system files, but that drive does not exist. To fix this problem, boot into the recovery environment and then run the bootrec /rebuildbcd command to rebuild the boot loader database with a list of valid operating system locations. You will not be able to boot into Safe Mode because the operating system files have not yet been loaded. The fixmbr and bootcfg commands were used on older versions of Windows.

Which of the following is a valid MAC address?

C0-34-FF-15-01-8E Explanation A MAC, or hardware address, is a unique identifier hard coded on every network adapter card. A valid MAC address has a total of 12 hexadecimal numbers. Hexadecimal numbers contain the numbers 0 to 9 and the letters A to F. Valid values in a MAC address range anywhere from 00 to FF. Note that one of the answers would be a valid MAC address except it uses a G value, which is beyond the range of a hexadecimal number.

A salesperson in your organization spends most of her time traveling between customer sites. After a customer visit, she must complete various managerial tasks, such as updating your organization's order database. Because she rarely comes back to your home office, she usually accesses the network from her notebook computer using Wi-Fi access provided by hotels, restaurants, and airports. Many of these locations provide unencrypted public Wi-Fi access, and you are concerned that sensitive data could be exposed. To remedy this situation, you decide to configure her notebook to use a VPN when accessing the home network over an open wireless connection. Which of the following key steps should you take when implementing this configuration? (Select TWO. Each option is part of the complete solution.)

Bridge Connects two network segments that have different subnet addresses. Router Connects segments on the same subnet. Repeats signals out to all other ports. Hub Operates in full-duplex mode, meaning devices can both send and receive data at the same time. Switch Operates in half-duplex mode, meaning devices can either send or receive data at any given time. Hub Uses the IP address within a packet to move packets between networks. Router

You are running Windows 10 on your computer. You want to decrease the time it takes to write data to your drives. To do this, you have decided to create a Windows software RAID system using a striped volume. Before you create the striped volume, which action MUST you take?

Convert basic disks to dynamic disks Explanation: When creating a Windows software RAID on Windows 10, all of the drive used for the RAID system must be configured as dynamic disks. The step of formatting your disks comes after the step of configuring your drives as either basic or dynamic. Like basic disks, dynamic disks can use the MBR or GPT partition styles on systems that support both. With older versions of Windows, a basic disk included a multi-partition volume. To encourage the use of dynamic disks, multi-partition volume support was removed from basic disks and is now exclusively supported on dynamic disks.

Which of the following refers to a situation where two files try to claim the same cluster on the hard disk?

Cross-linked clusters Explanation A cross-linked file error occurs when two files try to claim the same cluster. A lost cluster occurs when no file claims a cluster that has data within it. A corrupt MBR occurs when the master boot record on a system drive is corrupted. A SMART error occurs when a drive experiences a mechanical error.

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID 1 volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?

Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not. Explanation In this scenario, Disk 2 is shared between both volumes. If Disk 2 fails, the RAID 1 volume is still accessible because RAID 1 (mirrored) volumes can sustain a loss of a single disk. The data on the RAID 0 volume is not accessible. RAID 0 uses striping, which distributes the data evenly between multiple disks. If a single disk fails, the entire volume is lost.

You have physically installed a new hard disk drive in your computer and configured the disk in the BIOS using the CMOS setup program. You try to access the hard disk drive in Windows Explorer, but the drive is not displayed. Which of the following utilities will you MOST likely use to solve the problem?

Disk Management Explanation After physically installing a hard disk drive and configuring it in the CMOS, you need to partition the disk and format it with a file system using Disk Management. You can use the format command to format the disk, but it has to be partitioned first. The chkdsk command is used to scan the surface of a disk and locate bad sectors or other disk problems. The sfc command is used to verify the integrity of your Windows system files.

While configuring a computer, you find that you need to create, format, and manage the partitions and volumes on your hard drives. Which of the following is the BEST command line utility to use?

DiskPart Explanation DiskPart is the command line utility you can use to create, format, and manage partitions and volumes. Disk Management is the graphical utility you would use to do the same partition and volume creation, formatting, and management tasks you can do with DiskPart. DiskMan does not exist. format is a command line utility used to format disks for use with Windows. chkdsk is used to find and fix errors on disks, volumes, and files.

You have a computer running Windows 10 Home. You need to access the contents of a flash drive. The flash drive has been formatted with the exFAT file system. You want to read the flash drive on your computer as quickly as possible with the least amount of effort. What should you do?

Do nothing. Windows 10 can natively access exFAT file systems. Explanation exFAT is supported in Windows Vista SP1 and later. While you can use convert.exe to change the file system from FAT32 to NTFS, you cannot change it from exFAT to FAT32.

Which disk types does Windows support? (Select TWO)

Dynamic; Basic Explanation Windows supports basic and dynamic disks. When you install Windows, your hard disks are automatically initialized as basic. You can convert them to dynamic disks after Windows is installed. You can use both basic and dynamic disks on the same computer system, but a volume consisting of multiple disks, such as a mirrored volume, must use only one type of disk. "Primary" and "extended" are terms that describe partition types on basic disks.

You have just purchased a new USB drive that you want to use to troubleshoot the computers in your company as well as other network devices, such as printers and projectors. You need to format this new drive with a file system that will be recognized and used on all devices. When formatting your USB drive, which of the following file system types would meet MOST, if not all, of your needs?

FAT32 Explanation FAT32 is your best choice. Many of the older operating systems (and non-PC systems like printers, projectors, and TV sets) were initially installed or designed to use FAT32. Formatting your USB drive with any of the other file systems would make it incompatible with many of the devices you need to maintain.

Lately, you hear a clicking noise when reading or writing data from the hard disk. What is the most likely cause of the clicking?

Failing hard drive Explanation A clicking noise when reading or writing data from the hard disk is an early sign of a failing drive. As a precaution, you should move data from the drive as soon as possible in this case. An overheated CPU or bad power supply will cause a spontaneous reboot, not a clicking. A system notification would indicate whether there is a failed drive, as it would not allow reading or writing. A failed UPS (or failed battery in the UPS) would result in a complete loss of power to the computer if the outlet (or wall) power was lost.

A customer is upgrading the routers and switches in their network. The signal source in these network devices is a light-pulse. Which of the following network cabling options is MOST likely being used in this upgrade?

You are installing Windows 10 on a drive that was previously used for Windows 8.1. This drive has one primary partition. While installing Windows, you want to ensure that the old files are deleted and any bad sectors are located and marked as bad. To achieve your desired goal, which of the following is the BEST option to run?

Full format Explanation A full format starting with Windows Vista will overwrite data on the drive and scan the hard disk for bad sectors. A quick format does not overwrite data and does not check for bad sectors. DiskPart is a disk partition utility operated with the command line. Since your drive already has a partition, this utility is not required. Bootrec, or the bootrec.exe utility, is a tool provided by Microsoft in Windows Recovery Environment, or the Windows RE. It is typically used for activities such as fixing the master boot record.

You have an existing computer running Windows 10. You want to configure a RAID 1 array in the computer. You install two new SATA drives, then use the RAID controller integrated in the motherboard to define a RAID 1 array using them. When you boot the computer, Windows does not show the logical RAID drive. What should you do?

Install the drivers for the RAID controller. Explanation You must install the RAID driver so that Windows recognizes arrays created by the motherboard RAID utility. Without the driver, Windows will not be able to see the logical drive defined by the array. When you define the array, you configure the BIOS to use RAID as the SATA type. If you had not completed this step, you would not be able to run the RAID configuration utility. Use AHCI to configure SATA drives to support hot swapping.

You have an existing computer running Windows 10 Enterprise. You want to configure a RAID 5 array in the computer. You install three new SATA drives and then use the RAID controller integrated into the motherboard to define a RAID 5 array using them.

You are configuring a new system, and you want to use a RAID 0 array for the operating system using SATA disks and the RAID functionality built into the motherboard. Which of the following BEST describes the action you will take as part of the configuration?

Load the RAID drivers during operating system installation. Explanation If you are using an onboard RAID controller with SATA drives, edit the CMOS settings and identify the drive type as RAID. This tells the system to load the onboard BIOS for accessing the connected drives. If you want to install the operating system on a RAID array, you need to manually load the controller driver so that Windows can see the RAID array.

You are in the process of preparing a storage device and must determine which file system to use. Which of the following BEST describes the advantage of using the exFAT file system rather than NTFS?

Lower memory and processor resource use Explanation exFAT does not have the additional memory and processing overhead and problems that can occur on removable storage when using NTFS. Both exFAT and NTFS support volumes over 32 GB and files over 4 GB. While exFAT supports some limited file permissions, NTFS provides better control through granular permissions and access control lists.

You have just finished installing a new SATA hard disk in your computer. Now your SATA DVD drive won't work. Which of the following troubleshooting steps is the BEST to try first? (Select TWO).

Make sure that the DVD SATA cable is connected. Make sure that the DVD power cable is connected. Explanation The first thing to check is the simple and obvious. Make sure that the cable connecting the DVD drive is secure. It is possible that the cable came loose during the hard disk installation. All of the other choices would involve significantly more work. Master and Slave settings are not used on SATA devices. Moving the DVD drive to another system might make it start working, but you should verify the current configuration before trying that. You should only replace the DVD drive after you verify that it is not working correctly.

You have been asked to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link?

Mesh Explanation In a mesh topology, each network device is interconnected with all other network nodes. This creates multiple data paths. And in the event of a failed link, the data has an alternate route to arrive at its destination. The star topology connects network devices to the network with a single patch cable, and the failure of a patch cable will make the connected device unavailable. The bus topology has a single point of failure. If there is a break in the network media, the network will be unavailable. A single break in a physical ring topology will disable the network.

You have implemented an ad hoc wireless network that doesn't employ a wireless access point. Every wireless network card can communicate directly with any other wireless network card on the network. What type of physical network topology has been implemented in this type of network?

Mesh Explanation This type of network uses a physical mesh topology. There's no central connecting point. Any host can communicate directly with any other host on the network. A mesh network, such as this one, is usually impractical on a wired network. Each host would have to have a separate dedicated network interface and cable for each host on the network. However, a mesh topology can be implemented with relative ease on a wireless network due to the lack of wires.

You have a network that uses a logical bus topology. How do messages travel through the network?

Messages are broadcast to all devices connected to the network. Explanation Messages sent using a physical bus topology are broadcast to all devices in the network. The device in the middle of the star (typically a hub) receives the message and forwards it on to all other devices.

You have a network that uses a logical ring topology. How do messages travel through the network?

Messages travel from one device to the next until they reach the destination device. Explanation In a logical ring topology, messages travel to each device in turn. If the message is not intended for that device, the message is forwarded to the next device on the network.

To access the internet through the Publicly Switched Telephone Network (PSTN), what kind of connectivity device must you use?

Which of the following terms refers to a network resource sharing model that uses access control lists saved on each computer?

Peer-to-peer Explanation Access to shared resources are controlled separately on each computer in the peer-to-peer model (a Windows peer-to-peer network is called a workgroup). For example, each computer in a peer-to-peer network maintains its own set of user accounts. An intranet is a private network that uses internet technologies. Services on an intranet are only available to hosts that are connected to the private network. An extranet is a private network that uses internet technologies, but its resources are made available to external (but trusted) users. The client/server model places shared resources on a server. Resources are accessed by clients.

A group of workers in an office space communicate with each other on their smartphones and tablet devices through an ad hoc network linked using Bluetooth technology protocols. Which of the following network types is in use?

Personal Area Network (PAN) Explanation A piconet is an ad hoc network that connects personal devices and runs over Bluetooth technology. A piconet is an example of a PAN. A WAN covers a large geographical area and is made up of many smaller networks. A LAN covers a small local area and is used to connect workstations, printers, and other devices. A MAN covers a large campus or city and is smaller than a WAN.

You have added two new hard disks to a Windows computer. The disks are configured as basic disks. Which of the following could be configured on these disks? (Select TWO).

Primary partitions; Extended partitions with logical drives Explanation Basic disks use primary and extended partitions. Each physical disk can have up to four primary partitions or three primary partitions and one extended partition. Logical drives are defined within an extended partition. The extended partition can be divided into multiple logical drives. Dynamic disks support volumes that use discontiguous disk space. Simple volumes contain disk space from a single hard disk (both contiguous and discontiguous space). Spanned volumes contain disk space from multiple hard disks grouped into a single logical volume. Striped volumes use equal partition sizes on two disks to create a volume. Data is divided and saved to each disk

You replaced the ink cartridges in a color inkjet printer. Users are now complaining that print quality has degraded, lines are fuzzy, and the colored areas in images are starting or stopping before they should. Which inkjet maintenance task do you need to perform?

Printer cartridge calibration

You are building a new computer that will contain two hard disks. To provide increased performance, you have decided to configure the drives using RAID technology. Which of the following will BEST meet your needs?

RAID 0 Explanation RAID 0 (striping) uses two or more disks and provides an increase in performance, but not fault tolerance. RAID 1 (mirroring) uses two disks to provide fault tolerance, but not an increase in performance. RAID 5 uses a minimum of three disks and provides both fault tolerance and an increase in read performance.

A computer being used by the HR department needs to ensure that all of the data on that computer is protected from a single hard disk failure. The data needs to be read as quickly as possible, and the HR department would like to maximize drive use as much as possible. This computer can use up to three hard drives. Which of the following RAID types would meet these requirements and provide the BEST data protection?

RAID 5 Explanation A RAID 5 volume combines disk striping across multiple disks with parity for data redundancy. Parity information is stored on each disk. If a single disk fails, its data can be recovered using the parity information stored on the remaining disks. RAID 5 also provides an increase in performance for read operations. With three drives, RAID 5 uses approximately 33% overhead, whereas RAID 1 and 10 use 50%. RAID 0 does not provide fault tolerance. If one disk in the set fails, all data is lost. RAID 10 requires a minimum of four disks; this computer only has three.

Which of the following drive configurations uses striping with parity for fault tolerance?

RAID 5 Explanation RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. RAID 0 uses disk striping and offers no fault tolerance. A failure of one disk in the set means all data is lost. RAID 1 provides fault tolerance, but does not use striping. A RAID 10 array nests a mirrored array within a striped array.

What is an advantage of RAID 5 over RAID 1?

RAID 5 improves performance over RAID 1 Explanation RAID 5 provides both fault tolerance and improved performance. RAID 1 (mirroring) provides only fault tolerance with no performance benefit. Both RAID 5 and RAID 1 can only sustain a loss of one disk in the set. Use multiple disk controllers to provide redundancy for the disk controller.

A technician is installing a cable modem that supplies internet connectivity for a home office. Which of the following cabling types would be used to connect the cable modem to the cable wall outlet?

Which connector is used with unshielded twisted pair (UTP) cable?

RJ45

You have been asked to configure the drives in a computer. The end user wants to use striping without incorporating any fault tolerance. Which of the following will BEST meet these requirements?

Raid 0 Explanation RAID 0 uses disk striping and offers no fault tolerance. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. A failure of one disk in the set means all data is lost. This is the fastest of all RAID types. RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure. RAID 1 provides fault tolerance, but does not use striping. An expanded volume set is a volume that spans more than one hard drive. An expanded volume set also offers no fault tolerance, yet does not use striping.

One of your customers wants you to build a personal server that he can use in his home. One of his concerns is making sure he has at least one backup of their data stored on the server in the event that a disk fails. You have decided to back up his data using RAID. Since this server is for personal use only, the customer wants to keep costs down. Therefore, he would like to keep the number of drives to a minimum. Which of the following RAID systems would BEST meet the customer's specifications?

Raid 1 Explanation RAID 1 will protect memory from a single disk failure and provides high-read performance. It also only requires a minimum of two disks. RAID 5 would also protect data from a single disk failure, but requires a minimum of three disks, and RAID 10 requires a minimum of four disks.

Ben is concerned about losing data due to a hard disk failure. His computer will only support a maximum of three disks. To protect his data, you have decided to use RAID (redundant array of independent disks). Which of the following RAID types would give Ben the BEST mirrored data protection?

Raid 1 Explanation: RAID 1 is the only mirrored solution that can work on three or less drives. RAID 0 and RAID 5 protects data using stripping. RAID 10 uses mirroring, but requires a minimum of four disks.

An 8-port switch receives a frame on port number 1. The frame is addressed to an unknown device. What will the switch do?

Send the frame out ports 2-8 Explanation Because the switch does not know the port that is used to reach the destination device, it will send the frame out all ports except for the port on which the frame was received. After the switch learns the port that is used to reach the destination device, it will send the frame out only that port

You want to set up a Windows system to also be able to boot to Linux. To be able to dual boot, the system needs a partition on which to install Linux. However, you don't have an extra hard disk that can be used for the Linux partition. The existing disk has no unpartitioned space available, but it has about 300 GB of free space. Which of the following disk management operations will BEST prepare your hard disk for dual boot?

Shrink the primary partition Explanation You can decrease the space used by primary partitions and logical drives by shrinking them into adjacent, contiguous space on the same disk. For example, if you discover that you need an additional partition but do not have additional disks, you can shrink the existing partition from the end of the volume to create new unallocated space that can then be used for a new partition.

You have an extra disk on your system that has three primary partitions and an extended partition with two logical drives. You want to convert the partitions to simple volumes, preferably without losing any data. Which of the following is the BEST step to perform?

Upgrade the disk to a dynamic disk. Explanation When you upgrade a basic disk to a dynamic disk, existing partitions are converted to simple volumes. You can convert the disk without deleting partitions or losing any data. Use the Convert command to change the file system from FAT32 to NTFS. The partition table type (either MBR or GPT) does not affect the partition or volume type.

Your computer currently uses a 5,400 RPM hard disk. You want to improve your computer's overall performance by optimizing your hard disk performance. Which of the following would be the MOST effective means for optimizing your hard disk performance? (Select TWO).

Upgrade your hard disk interface to SATA 3. Upgrade to a 10,000 RPM hard disk. Explanation Upgrading to a 10,000 RPM hard disk and upgrading to a SATA 3 disk interface are the two most effective steps you can take to improve your computer's overall performance. The 7,200 RPM hard disk is not the fastest hard disk option. At 600 Mbps, the SATA 3 disk interface is twice as fast as the SATA 2 interface. Although hard disk drives are not capable of sending data at the full 600 Mbps, they can go faster than the SATA 2 interface allows. Implementing RAID 0 does improve hard disk performance, but it requires a minimum of two disks. Adding another hard disk while keeping your current 5,400 RPM disk would not improve your hard disk performance as much as upgrading to 10,000 RPM hard disk with a SATA 3 disk interface.

While changing the toner cartridge in your laser printer, you accidently spill toner in and around the printer. Which of the following is the BEST method for cleaning up the spilled toner?

Use a USB cable to connect the device to the network through a smartphone. Use a USB cellular antennae to connect the device directly to the cellular network.

You work for a small company as the human resources specialist. Since the company is fairly small, you are maintaining all of the employee information on your desktop computer, which is running Windows 10. This computer has two high-capacity hard disks. You want to ensure that this information is protected from a hard disk failure, so you want to set up a Windows software RAID system. Which of the following would be your BEST solution?

Use mirrored volumes. A Windows software RAID system can be configured in Windows 10 using the Windows Disk Management tool. Of the available options from within Disk Management, you would need to configure a mirrored volume to protect your data from a disk failure. Disk mirroring requires two available drives with sufficient storage. Once configured, the data written to a mirrored volume is duplicated to both drives. This duplication, or mirroring, means that if one of the mirrored drives fails, all of the data can still be retrieved from the remaining good drive. A spanned volume is a dynamic volume consisting of disk space on more than one physical disk. This method does not duplicate the data. If a spanned volume drive fails, the data is lost. A striped volume uses the free space on more than one physical hard disk to create a bigger volume similar to a spanned volume. However, a striped volume writes across all volumes in the stripe in small blocks, distributing the load across the disks in the volume. In other words, when a single file is written, some of the file will be on one disk, and the rest of the file will be on another disk. This makes writing files faster as the data to all of the disks in the strip at the same time. It does not, however, protect the data in the event of a disk failure. RAID 5 requires more than two disks.

For the past several days, the print jobs from the inkjet printer are missing colors and leaving gaps. Which of the following will MOST likely resolve the problem?

Use the automatic print head cleaning feature.
