A network technician is replacing a faulty SFP transceiver in a switch. What is the correct procedure to avoid damaging the transceiver or the switch?

Remove the transceiver while the fiber cable is still connected.

Use a screwdriver to pry the transceiver out of the port.

Power off the switch before removing the transceiver.

Disconnect the fiber cable, remove the transceiver, and install the new one.

In a fiber optic network, what role does the transceiver play in the communication process?

It converts the electrical signal from the switch into a light pulse for transmission over the fiber

It filters out noise from the optical signal

It terminates the fiber cable and provides a physical connection point

It regenerates the signal to overcome attenuation

A network engineer is connecting a switch to a fiber optic patch panel. The switch has an SFP port, and the fiber cable terminates with LC connectors. Which action correctly establishes the optical link?

Use an SC-to-LC adapter to convert the SFP port into an SC port.

Attach an RJ-45 connector to the fiber cable and plug it into the SFP port.

Connect the LC connector directly into the SFP port on the switch.

Insert an SFP transceiver into the switch port, then connect the LC connector to the SFP.

A technician is terminating a new Cat6a cable with an RJ-45 connector. What is the most important factor to ensure signal integrity?

Using a crossover wiring scheme.

Using a shielded connector even for unshielded cable.

Making the cable as short as possible.

Maintaining the twist of the wire pairs up to the point of termination.
