CompTIA Network+ (N10-007) — Question 264

After a server outage, a technician discovers that a physically damaged fiber cable appears to be the problem. After replacing the cable, the server will still not connect to the network. Upon inspecting the cable at the server end, the technician discovers light can be seen through one of the two fiber strands. Which of the following should the technician do FIRST to reconnect the server to the network?

Answer options

• A. Reverse the fiber strands of the cable and reconnect them to the server
• B. Use a TDR to test both strands of a new replacement cable prior to connecting it to the server
• C. Replace the server's single-mode fiber cable with multimode fiber
• D. Move the fiber cable to different port on the switch where both strands function

Correct answer: A

Explanation

The correct answer is A because reversing the fiber strands may resolve the issue if one strand is not functioning correctly. The other options do not address the immediate problem of connectivity, as testing a new cable or changing cable types would not help if the existing cable's strands are simply misaligned.
