You won't be able to boot to anything if you can't get past CMOS.

Ellen's laptop has a built-in 802.11n-capable wireless NIC. The wireless NIC worked perfectly yesterday when she loaned it to her nerdy friend Tom. Today, she cannot access the Internet via her wireless NIC. The NIC is not visible in Network Connections nor is it visible in Device Manager. What should she assume first? A) Nic is disabled in CMOS B)NIC is disabled in the Device Manager C) NIC is bad D) NiC's Hardware switch is set to off.

Correct Answer: A The NIC is disabled in CMOS. Granted, this is not a common problem, but of the options listed, it's the only one that would absolutely prevent the NIC from showing up in Device Manager. Incorrect Answer: In most cases, a hardware failure will not prevent a NIC from showing up in Device Manager. While there's no hard and fast rule here, a device with a hardware switch will still show up in both Device Manager and, in the majority of cases, in Network Connections as well. Disabled devices are still visible in Device Manager.

A stand-alone printer will print a test page just fine, but it makes gobbledy-gook out of your term paper. What's probably wrong? ​ A) Faulty driver ​ B) Out of toner ​ C) Missing printer interface ​ D) Fuser error

Correct Answer: A The driver that is installed is probably incorrect or corrupted. That will produce a print-out that is all messed up, while printing directly from the printer itself works just fine. Incorrect Answers: The fact that the test page works shows that the printer is working fine and has toner. A missing printer interface would keep the print job from getting to the printer completely.

One of the network printers is producing copies where the toner is smeared on paper after printing. What component should be checked? ​ A) Fuser ​ B) Paper output tray ​ C) Print spooler ​ D) Maintenance kit

Correct Answer: A Thermal and laser printers use a fuser to heat the toner to a melting point. Once melted, the toner will fuse with the fibers of the paper. Incorrect Answers: A maintenance kit is a kit of replacment parts. It may assist in the repair, but it is not a component. The paper output tray is only used once the printing process is complete. It will not effect the print job. The print spooler is a software based program that schedules print jobs; it does not effect the actual printing

A user installed a net SOHO router and new wireless NICs to increase his network's transmission speed from 802.11b to 802.11g. He didn't change the router from the manufacturer's default settings. The user lives in an apartment building and is still experiencing a slow Internet connection after the installations. Which of the following is the most secure option that a technician could implement to resolve this issue? ​ A) Disable the WAN port ​ B) Enable MAC filtering ​ C) Assign static IP addresses ​ D) Hide the SSID

Correct Answer: B It's very likely that the user's neighbors are stealing his Wi-Fi and slowing down his network. Enabling MAC filtering so that only the user's devices can join the network will keep his obnoxious neighbors at bay. Incorrect Answers: Hiding the SSID is a good idea, but a tech-savvy neighbor would still be able to join the user's network. Static IP addresses wouldn't help. Disabling the WAN port would mean that the user would be getting no Internet at all, which is the only thing worse than slow Internet. At least his neighbors would probably quit using his network.

What aspect of a regular vacuum cleaner makes it unsafe to use inside a laser printer? ​ A) Too much vibration ​ B)Too much static ​ C)Too much power ​ D)Too much voltage

Which of the following should the user do first? ​ A) Resynchronize the smart phone ​ B) Update the operating system ​ C) Restart the smartphone ​ D) Reconfigure the smartphone's e-mail account

Correct Answer: C "Have you tried turning it off and on again?" Sometimes restarting a device can solve unexpected problems. Incorrect Answers: If the problem persists after a restart, you might try to reset the e-mail settings. Syncing the phone probably won't solve the problem. An OS update would be the last resort, especially since phone OS updates are pretty rare, so your phone probably doesn't have one available

The rooms on the west side of a house do not get enough wireless signal to allow use of the wireless network. What can you do to fix this? ​ A) Buy a more powerful WAP ​ B) Upgrade to 802.11g ​ C) Install a second WAP ​ D) Install a router

Correct Answer: C Adding a second wireless access point (WAP) will extend the range of your wireless network. Incorrect Answers: WAPs can only be so powerful. The scenario does not tell us which 802.11 standard is being used, so switching to 802.11g might not be that helpful. A router will not increase the range of a wireless signal.

You set up all Windows 10 systems with TCP/IP and DHCP automatic addressing. One of the machines cannot connect to the network. You check its IP address with IPCONFIG and find that it has an address of 169.254.12.124. All the other machines in the network are working fine and you have confirmed that there are no cabling problems. How did this machine get this IP address, and what does it tell you? ​ A) Windows remembers the last IP address assigned and is trying to use that address. ​ B) Windows does not need an IP address to boot. ​ C) The IP is assigned by Automatic Private IP Addressing (APIPA) and this machine is not able to access the DHCP server. ​ D) This IP address indicates that someone manually assigned the address.

Correct Answer: C Automatic Private IP Addressing (APIPA) is generated by Windows and enables a computer to automatically assign an IP address if the Dynamic Host Configuration Protocol sever is not present. If the DHCP server is unavailable, the computer assigns itself an IP address in the range of 169.254.0.0 - 169.254.255.255. Incorrect Answers: Windows remembers the last IP address assigned and is trying to use that address. This might be true if automatic addressing was disabled and you were using a static IP address. This IP address indicates that someone manually assigned the address. It could have been manually assigned, but because it is in the range of what APIPA assigns, it would be better to assume otherwise. Windows does not need an IP address to boot.Very true, but also an absurd answer to this question.

An older network needs to labeled to show where each network connection terminates in a patch panel. Which of the following tools would be BEST for the technician to identify the connections? ​ A) Punchdown tool ​ B) Cable tester ​ C) Tone generator and probe ​ D) RJ-45 loopback plug

Correct Answer: C When a cable is plugged into a tone generator, it sends a tone through the cable that can be detected through a receiver called a probe. The probe can be pointed at each cable on the switch. When the probe touches the cable that is plugged into the tone generator, the tone can be heard through the probe. Incorrect Answers: An RJ-45 loopback plug is used to test the connection, not to find a cable. A punchdown tool is used to insert wire into a patch panel. A cable tester can only test a cable for electrical connection.

You are working on a laptop with an LCD screen that has dead pixels. What is the best way to get rid of them? ​ A) Replace the backlight ​ B) Replace the inverter ​ C) Replace the back bezel ​ D) Replace the LCD panel

Correct Answer: D Those pixels are defective and the LCD is failing to reproduce light levels correctly. The only way to fix this is to replace the LCD panel itself. Incorrect Answers: You should replace the inverter when you see nothing but a faint image on a dark screen. Replace the backlight(s) when the LCD screen starts to go dim or eventually just goes black. Replacing the back bezel might make your latop look brand new again, but it won't fix a dead pixel.

Which of the following cables is NOT used for networking computers? ​ A) UTP cable ​ B) STP cable ​ C) Plenum UTP cable ​ D) USB cable

Correct Answer: D USB cables are not used to network computers together. They are used to connect a computer to a peripheral such as a mouse or keyboard. Note: There are USB cables that exist in the world that have a small electronic circuit box in the middle of the cable that will allow you to connect two computers together. But that is a super special instance and the answer that I listed in the choices didn't say anything about it being that type of cable. Incorrect Answers: Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP) are the some of the most common ways of connecting computers together in a network. Plenum UTP cable is a type of network cabling that is suitable for being installed in air ducts or plenums.

You upgrade your network to 1000 Mbps from 100 Mbps. You install a new 1000-Mbps network adapter into your Windows system. You check the device manager and see no errors or warning. You configure the TCP/IP settings to be as they were for the previous network adapter. Upon restarting the computer, you cannot access the network. You ping your IP address locally and receive the error message, "Request timed out." You then ping 127.0.0.1 and receive the same error message. What do you do? ​ A)Replace the network cabling. ​ B)Set the network adapter to run at 100 Mbps only. ​ C)Replace the network card drivers. ​ D)Replace the NIC.

Correct Answer: D You tried to ping 127.0.0.1, which is the loopback address, as well as your local IP address and received the same error messages both times. This would indicate a faulty NIC in your workstation. Incorrect Answers: Nothing was changed about the cables, so that would not be the problem. Typically driver problems result in an error message during installation, so it's not the drivers. Also, you checked the device manager and everything was OK. Modern NICs can auto-negotitiate for speed, so setting it to run at 100 Mbps wouldn't really do much.

Don't forget to have a Class C fire extinguisher handy!

Kenneth has an 802.11n network. He only wants his three computers in the house to be able to access this network. Which of the following technologies would best enable him to do this? ​ A) MAC filtering ​ B) WPA filtering ​ C) DMZ filtering ​ D) Port filtering

Correct: A MAC filtering. MAC filtering creates allow or deny lists based on MAC addresses. Incorrect: WPA is a form of encryption. There is no such thing as WPA filtering. Filtering by TCP/UDP port number does not block particular systems. Many firewalls have the ability to filter ports based on IP address or MAC address using an Access Control List (ACL), but this isn't to be confused with pure port blocking. A Demilitarized Zone (DMZ) is used to expose certain systems to the Internet. It does not limit access to wireless clients.

The link light on the NIC of Rob's desktop normally glows yellow, but when he moved the PC to a construction trailer and plugged it in, it glowed green.
