IT1600 PC Tools
Which tool would you use to grab and lift small objects?
3-prong holder
Which of the following tools can help prevent damaging 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 would 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. AC is the voltage input for a power supply. To measure the input, measure the power from the wall socket. An ohm is a measure of resistance used to check the properties of a resistor. Multimeters can measure amps, but do not measure watts.
You are removing screws within a computer, but several have fallen into places you can't reach. Which tool would help retrieve the small screws?
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 Explanation: 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. POST card displays output from the BIOS during the Power-On-Self-Test(POST). Known good spares are a set of components that you know are in proper functioning order such as psu or expansion cord.
A printer is behaving erratically, and you suspect a faulty parallel port. Which tool can you use to test the parallel port?
Loopback plug
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
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
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?
Tone generator Explanation: A tone generator is used to trace a UTP cable through walls and ceilings. A tone generator is attached to one end of the cable. Then the probe is used to audibly trace the wire.
A maintenance worker accidentally nicks a bundle of network cables routed to multiple wall jacks in a conference room. Only one of the cables wires are severed. A technician is tasked with replacing the cable. Which of the following tools would the technician MOST likely use to identify which wall jack connects to the severed cable?
Tone generator and probe Explanation: A tone generator and probe can be used to identify the wall jack connected to the severed wire. 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
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 Explanation: A failing power supply can cause the computer to continuously reboot. For example, pin eight on the power supply connector connects to the power good wire on the motherboard. If power disappears from that wire, the motherboard shuts down. If power quickly reappears on that wire, the system may attempt to come back on by itself, which causes the symptom of continual reboots. Using a multimeter allows you to verify the amount of voltage supplied by the power supply. You could replace the power supply, but it is best to test the original power supply first, as other issues may be causing the reboots. A running fan is not a good indication of a properly functioning power supply, since the fan may be running, but the power supply is not supplying the correct voltage for other components to run properly. Some BIOS may have a POST beep code that can give you a clue about failing power supply, but this is not reliable method for determining that the power supply is bad and needs to be replaced, and you may not have spare power supplies on hand to use
