CompTIA Network+ (N10-008) — Question 397

A technician troubleshoots a computer that has intermittent network connectivity and notices the termination point is loose. The technician also observes that the patch cable has already been replaced.

Which of the following should the technician do NEXT?

Answer options

• A. Use a tone generator to trace the cable
• B. Use a multimeter to determine if PoE is available on the switchport
• C. Use a cable crimper to replace the RJ45 connector on the patch cable
• D. Use a punchdown tool to reseat the copper in the wall jack

Correct answer: D

Explanation

The correct action is to use a punchdown tool to reseat the copper in the wall jack to ensure a secure connection. The other options do not address the immediate issue of a loose termination point. Using a tone generator or multimeter may help diagnose the problem, but they do not resolve the connectivity issue directly.
