Transceivers for Fiber Cable Connections

A new technician is connecting an access switch to a distribution switch uplink in a datacenter using fiber cables.

Which of the following are transceivers the technician should use to perform this job? (Choose two.)

A.

RJ45

B.

DB-9

C.

LC

D.

SFP

E.

GBIC

F.

SC.

DE.

The correct answers for this question are C. LC and D. SFP.

Explanation: When connecting a switch to another switch via a fiber uplink, the technician needs to use transceivers that are compatible with the type of fiber cable being used. The most commonly used fiber connectors are LC and SC, but LC is more commonly used in datacenters because it has a smaller form factor and is easier to work with.

The SFP (Small Form-factor Pluggable) transceiver is a hot-swappable component that can be plugged into a switch or router to provide connectivity to the network. It supports different types of fiber cables, including single-mode and multi-mode fiber, and it allows for easy replacement and upgrade of network connections.

Therefore, the technician should use LC connectors on the fiber cable ends, and SFP transceivers on both the access and distribution switches to establish the fiber uplink connection.
