Question
A technician is troubleshooting a computer that doesn't start up correctly.
Which of the following could the technician use to troubleshoot the computer?
answer
Tone generator and probe
3-prong parts retriever
Known good spares
Loopback plug
Solution
The technician could use "Known good spares" and "Loopback plug" to troubleshoot the computer.
-
Known good spares: These are components that the technician knows are in good working order. The technician can swap out potentially faulty parts in the computer with these known good spares to see if the problem persists. If the problem is resolved after swapping a part, then the technician knows that the original part was faulty.
-
Loopback plug: This is a device used to test the ports in a computer. The technician can plug it into a port, and it will send a signal back to the computer. If the computer receives the signal, then the technician knows that the port is working correctly. If the computer does not receive the signal, then the technician knows that there is a problem with the port.
The other two options, "Tone generator and probe" and "3-prong parts retriever", are not typically used for troubleshooting a computer that doesn't start up correctly. A tone generator and probe are used for tracing and identifying wires and cables, while a 3-prong parts retriever is a tool used to retrieve small items from hard-to-reach places.
