3-prong holder
Which of the following tools can help prevent damage when working with computer components?
Antistatic pad and wrist strap
You suspect that the power supply in your desktop PC is failing. You want to use a multimeter to test the power supply. Which multimeter setting should you use?
DC volts EXPLANATION To measure the output of a power supply, measure DC voltage. A power supply converts AC voltage to DC voltage and supplies the DC power to computer components.

Extension magnet
Which tool would be the best choice for removing and replacing the motherboard BIOS chip?
IC extractor
A technician is troubleshooting a computer that doesn't start up correctly. Which of the following tools could the technician use to troubleshoot the computer? (Select TWO).
Known good spares POST Card
A printer is behaving erratically, and you suspect a faulty parallel port. Which tool can you use to test the parallel port?
Loopback plug EXPLANATION Loopback plugs are used to test serial and parallel ports.
Your workstation is unable to communicate with any other computer on the network. Which of the following tools should you use to test the network card's abilities to send and receive signals?
Loopback plug EXPLANATION Use a loopback plug to test the network card's ability to send and receive signals.
Which tool would you use to measure electrical properties such as voltage, amps, and resistance?
Multimeter
Which of the following tools is specifically designed to test the DC voltage on a hard disk drive power connector?
Power supply tester
Which of the following BEST describes the purpose for which loopback plugs are used?
Testing ports by returning output signals as input. EXPLANATION Loopback plugs are used to test ports by returning output signals as input. Use a loopback plug to test the functionality of serial ports or networking ports.
You need to trace the route that a Cat 6 UTP cable takes through the ceiling and walls of your building. Which tool should you use?

You are an IT technician for your company. One of your employees has a computer that continually reboots when it is powered on. He has asked you to fix it. You suspect that the power supply may be failing. Which of the following is the BEST way to determine whether the power supply is causing the reboots?
Use a multimeter to test the power supply.
The POST card
displays output from the BIOS during the Power-On Self-Test (POST).
A tone generator and probe can be used to
identify the wall jack connected to the severed wire.
An IC extractor
is a tweezer-like tool, usually spring-loaded in the open position, used to remove integrated circuit chips.
A POST card
is an expansion board that you insert into an expansion slot. It is typically used to troubleshoot a computer system that doesn't start up correctly.
A loopback plug can be
plugged into a network adapter to test whether the NIC can send and receive properly.
The tone generator can be attached to
the severed wire, and the probe will sound when it is brought close to the connected wall jack.
A cable tester
verifies that a network can carry a signal from one end to the other and that all wires within the connector are in their correct positions.
