Chapter 20: Hardware and Network Troubleshooting Flashcards
If the video on your laptop is not working, what should you do to troubleshoot it?
(Choose two.)
A. Toggle the video function key.
B. Try using an external monitor.
C. Remove the display unit and reattach it.
D. Power the system off and back on.
A, B.
Two helpful things to try are toggling the video output function key (usually Fn+F8)
and plugging an external monitor into the laptop.
Removing the display is possible but not recommended.
Powering the system off and back on isn’t likely to correct the problem.
While inspecting a motherboard, you notice a discolored area.
What is usually a cause of this?
A. Spilled liquid
B. Improper manufacture
C. Power surge
D. Underclocking
C.
Discolored areas on the board are often caused by overheating.
This can be the result of power surges.
You need to connect a client computer to a shared network drive from the command prompt. Which command should you use? A. NET USE B. NETSTAT C. NSLOOKUP D. IPCONFIG
A.
The NET USE command allows you to connect to shared resources such as shared drives
and printers on the network.
Every computer has a diagnostic program built into its BIOS called the __________.
A. CMOS
B. BIOS
C. POST
D. DNS
C.
Every computer has a diagnostic program built into its BIOS called the power-on selftest
(POST).
The BIOS is the software stored on the CMOS chip.
DNS is Domain Name Service, which in networking resolves hostnames to IP addresses.
While troubleshooting a client computer, you decide to obtain a new IP address from the
DHCP server.
After releasing the existing address, which command do you use to get new
IP information from the DHCP server?
A. IPCONFIG /REFRESH
B. IPCONFIG /RENEW
C. IFCONFIG /RELEASE
D. IFCONFIG /START
B.
Explanation: The IPCONFIG command is perhaps the most used utility in troubleshooting
and network configuration.
The IPCONFIG /RENEW command will send a query to the DHCP server asking it to resend and renew all DHCP information.
For a more detailed look at the IPCONFIG command, type IPCONFIG /? at the command prompt.
Users are complaining that their print jobs are not printing.
You open the print queue and see 50 jobs lined up.
The printer is connected properly and online.
What should you do?
A. Open Printer Troubleshooting and have it diagnose the problem.
B. Stop and restart the print spooler.
C. Delete and reinstall the printer.
D. Delete and reinstall Windows.
B.
If print jobs are seemingly getting “stuck” in the printer queue, you should stop and
restart the print spooler service.
There is no Printer Troubleshooting utility that will diagnose printer problems.
Deleting and reinstalling is not necessary.
What two devices are commonly used to cool components within a PC? (Choose two.)
A. Fans
B. Compressed air
C. Freon
D. Heat sinks
A, D.
Heat sinks and fans are commonly used to cool components within a PC.
Compressed air can be used to blow out small particles or dust.
Freon is a coolant used in some air conditioners but is not typically used for personal computers.
You are having problems with the video card in one of your computers.
Where could you check for troubleshooting information?
A. Another computer with the same video card
B. The video card manufacturer’s website
C. The manual that came with the card
D. The server log
B.
The manufacturer’s website is the first place you should go for information on your
products, including troubleshooting information.
Many years ago, manufacturers would provide paper manuals with their products, but that’s almost unheard of today.
Server logs can show error codes but won’t tell you how to fix anything.
Your laser printer keeps printing vertical black lines on its output pages.
What is the most likely cause of the problem?
A. There is a groove or scratch in the EP drum.
B. The EP drum cleaning blade is broken.
C. The printer is low on toner.
D. The transfer corona wire is not working properly.
A.
The most likely cause is a groove or a scratch in the EP drum.
Toner is collecting in that groove or scratch and then being deposited on to the page.
The display on your laptop appears warped and fuzzy.
You plug in an external monitor, and the image on it is fine.
What is the most likely cause of the problem?
A. The video card
B. The LCD display
C. The motherboard
D. The video driver
B.
It has to be a problem with the LCD display.
If it were the video card, then the display would appear warped and fuzzy on the external monitor as well.
While many motherboards contain video circuitry, this answer is not specific enough.
If the video driver were corrupted, you would have the same problem on all displays.
You have an inkjet printer.
Recently, papers are being printed with excessive amounts of ink, and the ink is smearing.
What is the most likely cause of the problem?
A. A faulty ink cartridge
B. A corrupt print driver
C. A faulty fuser
D. Too much humidity in the air
A.
If an ink cartridge is faulty or develops a hole, it can release excessive amounts of ink,
which will lead to smearing.
A corrupt print driver would result in printing garbage.
Inkjet printers do not have a fuser.
Excessive humidity may cause smearing, but it wouldn’t cause the disbursement of too much ink.
You are working with a system that is assigned IP information configuration information
from a central server.
You wish to view the IP information on the system.
Which of the following commands would you use from the command prompt?
A. IPCONFIG /REFRESH
B IPCONFIG /ALL
C. IPCONFIG /RENEW
D. WINIPCFG /ALL
B.
The ipconfig utility can be used with Windows to see the networking configuration values
at the command line.
It is one of the most commonly used command-line utilities that can be used in troubleshooting and network configurations.
To view IP configuration information, use the IPCONFIG /all command.
When you print documents on your laser printer, you see residue from previous images on the output.
What two things are the most likely causes of this problem? (Choose two.)
A. A faulty transfer corona wire
B. An overheating printer
C. A bad erasure lamp
D. A broken cleaning blade
C, D.
Seeing images from previous print jobs is a phenomenon called ghosting.
It’s most likely due to a bad erasure lamp or a broken cleaning blade.
You turn a computer on, but nothing shows up on the monitor.
Instead of one beep, you hear one long beep followed by three short beeps.
What is the problem?
A. The video card is dead.
B. The motherboard is dead.
C. The BIOS is not functioning.
D. Not enough information; you need to look up the beep code to determine the problem.
D.
It may well be that the video card is dead. Different BIOS manufacturers use different
beep codes, though, so you’ll want to look it up to be sure.
If the motherboard was dead or the BIOS wasn’t functioning, you wouldn’t get to the POST routine, so you wouldn’t get a beep code.
Which of the following command-line utilities is used to verify the route a data packet
takes to a remote host?
A. Trace
B. Tracert
C. TraceRoute
D. Tracepacket
B.
Tracert is a command-line utility that enables you to verify the route to a remote host.
It is often used in the troubleshooting process to verify the path a data packet takes toward its final destination.
