CompTIA Network+ (N10-009) — Question 347

A network administrator needs to connect a multimode fiber cable from the MDF to the server room. The administrator connects the cable to Switch 2, but there is no link light. The administrator tests the fiber and finds it does not have any issues. Swapping the connection to Switch 1 in a working port is successful, but the swapped connection does not work on Switch 2. Which of the following should the administrator verify next?

Answer options

• A. Fiber length
• B. Transceiver model
• C. Connector type
• D. Port speed

Correct answer: B

Explanation

The correct answer is B because the transceiver model must be compatible with the switch and the fiber type being used. If there is a mismatch in the transceiver model, it can prevent a successful connection, even if the fiber cable is in good condition. The other options, such as fiber length, connector type, and port speed, are less likely to be the issue since the cable works on Switch 1.
