Front

The last step of the troubleshooting process should involve:

Back

Documenting findings, actions, outcomes, and conclusions

Front

To ensure proper functioning of single-mode fiber-optic connections and prevent issues such as signal degradation or data errors, it is essential to use transceivers and connectors specifically designed for single-mode applications. True or False?

Back

True

Front

What would be the possible outcome of using a multimode fiber for long-distance communication links reserved for single-mode fiber optics?

Back

All of the above

Front

What step should a network technician take if Cat 5 cables are found in a Gigabit Ethernet connection?

Back

Replace Cat 5 cables with Cat 5e or higher

Front

A network technician discovers a 50-meter-long Cat 6 cable being used for a 10 Gigabit Ethernet connection. What should the technician do?

Back

Leave the network link as is

Front

What action should a technician take to ensure optimal bandwidth when using a Cat 8 cable for 40 Gigabit Ethernet over a 100-meter segment? Options: Switch to twinaxial cabling, Use repeaters to amplify the signal, Switch to fiber optics, Maintain the current setup

Back

Switch to fiber optics

Front

Which type of twisted-pair copper cabling takes advantage of an additional protective cover reducing signal interference from outside sources?

Back

STP

Front

A key feature of all twisted-pair cabling types is that wires inside the cable are grouped into pairs, and the wires in each pair are twisted around each other to reduce signal interference from adjacent wire pairs.

Back

True

Front

Back

UTP cabling

Front

Which type of network cabling provides immunity against EMI and RFI? Options: Coaxial, UTP, Twinaxial, STP, Fiber optic

Back

Fiber optic
