Question

a technician is running a network above a dropped - ceiling that is also used for ventilation. the cable must be twisted - pair and must be capable of gigabit ethernet speeds. which of the following cables should the technician use?
riser - rated cat 5e
plenum - rated cat 6a
riser - rated rg - 58
plenum - rated multimode fiber

Explanation:

Step1: Understand cable requirements

The cable is for a network above a dropped - ceiling used for ventilation, needs to be twisted - pair, and support Gigabit Ethernet speeds.

Step2: Analyze each option

Riser - rated Cat 5e is not suitable for ventilation areas as it is not fire - rated for plenum spaces. Plenum - rated Cat 6a is a twisted - pair cable, fire - rated for plenum spaces (ventilation), and can support Gigabit Ethernet speeds. Riser - rated RG - 58 is coaxial cable, not twisted - pair. Plenum - rated multimode fiber is fiber optic, not twisted - pair.

Answer:

Plenum - rated Cat 6a
