CompTIA Network+ (N10-007) — Question 139

A network technician is assisting a user who has relocated to a newly constructed office space. The user has no network connectivity. A cable tester was used on the port and is reporting that the pairs are open. Which of the following should be used to remedy this problem?

Answer options

• A. Loopback adapter
• B. Tone generator
• C. Multimeter
• D. Punchdown tool

Correct answer: D

Explanation

The correct answer is D, the Punchdown tool, which is used to connect wires to a patch panel or wall jack. The open pairs indicate that the connections are not properly made, and the Punchdown tool will help secure those connections. The other options, such as the Loopback adapter, Tone generator, and Multimeter, do not address the issue of physical wire termination directly.
