Q

Which of the cabling types listed below provide(s) protection against an outside signal interference?

A

Coaxial
Fiber-optic
STP

2
Q

One of the differences between the UTP and STP cabling is that the STP cable takes advantage of additional protective cover reducing signal interference from outside sources.

A

True

3
Q

In twisted-pair cabling wires are grouped into pairs and wires in each pair are twisted around each other in order to reduce:

A

Cross-talk

A

CAT6

10
Q

The Category 6 (CAT6) cabling supports 10 Gbps data transfer rate at a limited range of up to 55 meters, whereas CAT6A (Augmented) cabling allows for 10 Gbps data transfer rate over a standard cable segment length of 100 meters.

A

True

11
Q

The term “Plenum” refers to an enclosed space used for airflow, such as the one between dropped ceiling and structural ceiling in a building. Cabling coated with a fire-retardant jacket placed in this space is referred to as plenum-rated cabling. Plenum-rated cabling must meet special requirements so that it doesn’t catch on fire easily.

A

True

12
Q
