Test 3

You are called to look at a co-workers computer. It is not powering on, no fans start, there is no sound, and no lights turn on when the power button is pushed. What should you do first? A) Check the power cable B) Replace the power supply C) Replace the CMOS battery D) Check the boot sequence in the BIOS/UEFI

A) Check the power cable (Objective 4, Hardware and Network Troubleshooting)

A user working in a warehouse calls and tells you that his computer keeps freezing or rebooting at random, it makes an annoying high-pitch squeak/squeal when running. What is likely to be the issue? A) Overheating/fan issues B) Battery not charging C) Sticking keys D) Bad driver software

A) Overheating/fan issues Warehouses are often very dusty, which could cause a fan to stop working and promote overheating. These symptoms (freezing/rebooting) indicate overheating, so the noise could be a failing fan. (Objective 4, Hardware and Network Troubleshooting)

You are having issues connecting/consoling to a Linux server hosting a database of customer information from your home machine, you think the problems are being caused by a blocked port on your firewall. Which port on your firewall is likely to cause this sort of an issue if blocked? A) Port 22 B) Port 23 C) Port 80 D) Port 3389

A) Port 22 Port 22 (SSH) is used for secure communications such as console connections to a remote server. Port 23 is for TELNET and is not a secure connection. It is unlikely (or a horrible practice) that TELNET would be used to connect to a sensitive database. Port 80 is for HTTP traffic, not for console connections. Port 3389 is for RDP, and would not usually be used for a console connection but a remote desktop connection. (Objective 2, Networking)

You are configuring a static IP address on a Windows system and realize the netmask is written as "/25," what is the proper way to input this into the network configuration for this system? A) /25 B) 255.255.255.128 C) 255.255.255.192 D) 255.255.255.0

B) 255.255.255.128 Windows does not allow you to input CIDR for network configurations. 255.255.255.192 is a /26 netmask, 255.255.255.0 is a /24 netmask. (Objective 2, Networking)

A user complains that he can no longer see any wireless networks, connect to his bluetooth headset, or make phone calls on his Android phone. Which of the following options would best address these issues? A) Dial *228 B) Disable Airplane Mode C) Ensure the phone is not overheating D) Try using the phone outdoors

B) Disable Airplane Mode (Objective 3, Mobile Devices)

A) Replace your mouse, it has caused driver issues with the touchpad B) Disable the touchpad, see if the problem persists C) Ensure none of the arrow keys are stuck D) Ensure that Scroll Lock is on

B) Disable the touchpad, see if the problem persists (Objective 4, Hardware and Network Troubleshooting)

Your boss wants you to come up with a solution for allowing people to easily move their laptops between work and home without having to move and reconnect their mouse, keyboard, network, monitor, etc. What technology will enable this? A) Cable lock B) Docking Station C) Wireless D) USB Hub

B) Docking Station A docking station is the only listed choice that will allow you to quickly connect a monitor, network cable, and input devices to the laptop. A cable lock is a physical security device. Monitors do not typically support a wireless connection, and a USB hub does not usually support monitor output or network connections. (Objective 3, Mobile Devices)

You sit down at an unfamiliar server with a black prompt, you decide to identify the server by checking its IP address. You type ipconfig and it responds "bash: ipconfig: command not found...," what command will likely give you the information you're looking for? A) Netstat B) Ifconfig C) Nslookup D) Tracert

B) Ifconfig Since the computer is likely a Linux/Unix (-nix) machine, ifconfig is the appropriate command to find the IP address in a -nix OS. Netstat will show active connections but not the IP address. Nslookup is for querying DNS. Tracert is not likely to work on a *nix box, nor will it display for IP since it is used for showing path information to a remote system. (Objective 2, Networking)

You need to make a backup of a small database storing customer information for historical records. The database is about 5.5 GB in size. Of the options, which is the best storage media for this task? A) CD-R B) CD-RW C) DVD-R D) DVD-R DL

D) DVD-R DL Of the options provided DVD-R DL (DVD-Recordable Dual Layer) is the only one with the capacity (8.5GB) to support this. Both CD options have a 0.7GB capacity, and a DVD-R has a 4.7GB capacity. (Objective 1, Hardware)

What type of network cabling has 2 pairs and traditionally only utilizes 1 of the pairs? A) RJ-11 B) RJ-45 C) Coax D) 4-pin 12V

A) RJ-11 RJ-11 supports both a 1 (2 wire) and 2 (4 wire) pair configuration, typically used in telephone systems. Only 1 pair is traditionally utilized. RJ-45 has 4 pairs (8 wires), Coax has 1 wire, and 4-pin 12V is for power supplies. (Objective 1, Hardware)

There is a network (RJ45) port in your office, recently it stopped working. There is no connectivity provided when you plugin to it. The cable and your NIC are known-good, you need to make sure the cable on the back-end of the port is connected but the wiring closet is a disaster. Which tool will assist with this? A) Tone generator/probe B) Loopback plug C) PING D) Cable tester

A) Tone generator/probe Tone generator/probe will help you identify which cable runs to your office so you can see if it is connected. A loopback plug is for testing the NIC, which we already confirmed good. PING is an application/command used to test network connectivity, it won't help here. A cable tester would likely be the next tool used once we find our cable and confirm that it is connected. (Objective 4, Hardware and Network Troubleshooting)

Your company is planning on issuing all management employees an iPhone 6S and an iPad pro. All of the work stations in the office have USB ports; what type of cable is needed to connect these new devices to their work station? A) USB to Lightning cable B) USB to USB C cable C) USB to USB mini cable D) USB to MicroUSB cable

A) USB to Lightning cable (Objective 3, Mobile Devices)

You want to move from using physical servers to using virtual servers/machines (VMs) while utilizing the same hardware that is currently in place. You need to make sure this is possible, what feature must your CPU support? A) Virtualization B) Hyperthreading C) Multiple cores D) Dual voltage options

A) Virtualization (Objective 1, Hardware)

You have been tasked by the Network Team to assign a server a new static IP address. You are receiving an error when attempting to apply the IP 172.256.1.15 with a subnet mask of 255.0.0.0. What is the issue causing the error? A) The DHCP server isn't assigning an IP address, so it has generated an APIPA address B) The IP address is invalid C) 172 is a class bravo IP but the subnet is class alpha D) There is not enough information provided to determine the problem

B) The IP address is invalid (Objective 4, Hardware and Network Troubleshooting)

Your supervisor decides he wants to transition the office from a fiber connection to a satellite connection. The office relies on the connection for VoIP, email and cloud storage. You find that the prices for satellite connections are cheaper. Why would you advise against this change? A) You don't, saving money and no performance change is a great idea B) The latency from the satellite connection would adversely impact VoIP C) This would likely require re-wiring the whole network, outweighing any cost savings D) Encryption is not available over satellite connections this could be a compliance/security issue

B) The latency from the satellite connection would adversely impact VoIP Satellite connections often have notable delay/latency issues which would be unacceptable for VoIP and video conferences, they are also negatively impacted by weather. The hand-off for satellite is likely RJ-45 or something similar. You may need a new modem but rewiring the entire network is an unlikely requirement. Satellite connections can be used with encryption. (Objective 2, Networking)

The clock on your computer keeps falling out of sync, you have to set it each time you restart the computer or power it on. The offset is never consistent. What should you do to correct this issue? A) Check the timezone settings B) Replace the fan, the system is overheating C) Replace the CMOS battery D) Ensure that port 321 is not blocked

C) Replace the CMOS battery (Objective 4, Hardware and Network Troubleshooting)

You are in charge of purchasing new computers for the office, they need to "boot fast and store large video files for editing, don't blow your budget either." The systems only have room for one type of storage device and one type of optical device. What is the best drive to meet these requirements? A) SSD B) HDD C) Hybrid Drive D) Tape Drive

C) Hybrid Drive A hybrid drive is more affordable than an SSD and quicker than a HDD. A tape drive is more of a backup tool, and is slow, not ideal for regular use as described. (Objective 1, Hardware)

An old Linux server is having USB driver problems and your co-worker needs to bring a different type of keyboard or an adapter. What type of keyboard/adapter is likely needed? A) Lightning B) Firewire C) PS/2 D) Bluetooth

C) PS/2 (Objective 1, Hardware)

You're setting up a SOHO and want to setup a dedicated backup server with 2 HDDs. You will be backing up valuable files like family pictures and tax forms, so you value redundancy and reliability over speed. What is the best configuration for this server? A) Dualcore Processing B) RAID 0 C) RAID 1 D) RAID 5

C) RAID 1 RAID 1 is the only technology that meets the goals stated (redundancy) for the current setup. Dualcore processing is for processing, not storage/backups. RAID 0 is for speed, not redundancy. RAID 5 offers redundancy but requires 3 or more storage devices, you only have 2 HDDs. (Objective 1, Hardware)

There is a printer shared via Windows File and Printer sharing on your SOHO network. When your husband attempts to print he receives an "Access Denied" error. Where should you look to correct this issue? A) The Security tab under Printing Preference on your husband's computer B) The Security tab under Printing Preference on the host computer C) The Security tab under Printer Properties on your husband's computer D) The Security tab under Printer Properties on the host computer

D) The Security tab under Printer Properties on the host computer The Security tab under Printer Properties on the host computer is where you set the permissions for a shared printer. There is no Security tab under Printing Preferences which is where you set print quality, paper orientation, etc. (Objective 4, Hardware and Network Troubleshooting)
