CompTIA Network+ (N10-007) — Question 677

Ann, a network technician, has relocated a rack that contains the networking and server equipment from the third floor to the sixth floor. To connect the rack- mounted router to the media converter in the first-floor MDF, she extended the length of the original 197ft (60m) Cat5e cable to 395ft (120m) by attaching another
197ft (60m) cable with an RJ45 coupler. After the move, users report intermittent connectivity to external websites, although connectivity to internal hosts has not changed. Which of the following is a network performance issue that is MOST likely causing this issue?

Answer options

• A. Attenuation
• B. Jitter
• C. Crosstalk
• D. Transceiver mismatch

Correct answer: A

Explanation

The correct answer is Attenuation, which refers to the loss of signal strength over longer distances. Since the total length of the Cat5e cable was extended to 395ft, it likely exceeds the recommended maximum length for optimal performance, leading to connectivity issues. Jitter, crosstalk, and transceiver mismatch are less likely to be the cause in this scenario, as the problem is primarily related to the distance and signal degradation.
