CompTIA Network+ (N10-007) — Question 678

A network technician is planning to upgrade an end-of-life network switch and wants to reuse as much of the existing infrastructure as possible. The end-of-life switch uses a GBIC, but the new switch will use an SFP. Which of the following will the network technician MOST likely need to perform before completing the upgrade?

Answer options

• A. Reterminate the fiber with ST connectors.
• B. Reterminate the fiber with SC connectors.
• C. Reterminate the fiber with LC connectors.
• D. Reroute the fiber through a media converter.

Correct answer: C

Explanation

The correct answer is C because SFP modules typically use LC connectors, and reterminating the fiber with LC connectors will ensure compatibility with the new switch. Options A and B are incorrect as they refer to different connector types that do not match the requirements of the SFP. Option D is also incorrect as rerouting through a media converter is unnecessary when a direct connection can be established by reterminating with the correct connectors.
