CompTIA Network+ (N10-009) — Question 74

After installing a series of Cat 8 keystones, a data center architect notices higher than normal interference during tests. Which of the following steps should the architect take to troubleshoot the issue?

Answer options

• A. Check to see if the end connections were wrapped in copper tape before terminating.
• B. Use passthrough modular crimping plugs instead of traditional crimping plugs.
• C. Connect the RX/TX wires to different pins.
• D. Run a speed test on a device that can only achieve 100Mbps speeds.

Correct answer: A

Explanation

The correct answer is A because using copper tape can help reduce electromagnetic interference, which may be contributing to the increased interference observed. Option B is incorrect as the type of crimping plugs does not directly address interference issues. Option C is also wrong, as connecting RX/TX wires to different pins can lead to communication errors rather than solving interference. Lastly, option D does not resolve the interference problem and instead tests a device with a known speed limitation.
