CompTIA Network+ (N10-008) — Question 387

A fiber patch cable, which was being stored in an unsecure telecommunications closet with janitorial supplies, was damaged and caused an outage. A network technician replaced the broken cable with a new cable from a sealed bag. However, this solution did not resolve the outage. Which of the following is the MOST likely explanation?

Answer options

• A. Incorrect pinout
• B. Incorrect transceivers
• C. Reversed transmit and receive
• D. Dirty optical cables

Correct answer: C

Explanation

The most likely reason for the outage is that the transmit and receive signals are reversed, which would prevent proper communication. The other options, such as incorrect pinout or transceivers, could cause issues, but the technician replaced the cable from a sealed bag, making it less likely for those errors to occur. Dirty optical cables could also be problematic, but the new cable should not have that issue if it was sealed properly.
