CompTIA Network+ (N10-008) — Question 449

An AP uses a 98ft (30m) Cat 6 cable to connect to an access switch. The cable is wired through a duct close to a three-phase motor installation. Anytime the three-phase is turned on, all users connected to the switch experience high latency on the network. Which of the following is MOST likely the cause of the issue?

Answer options

• A. Interference
• B. Attenuation
• C. Open circuit
• D. Short circuit

Correct answer: A

Explanation

The correct answer is A, as the high latency is likely caused by electromagnetic interference from the three-phase motor affecting the performance of the Cat 6 cable. Attenuation would typically affect signal strength over long distances, while an open or short circuit would result in a complete loss of connectivity, not just latency issues.
