CompTIA Network+ (N10-007) — Question 398

A network technician needs to install new network cables. The technician will be running the cables in the air return space above the drop ceiling. Which of the following cable types should be installed?

Answer options

Correct answer: A

Explanation

Plenum-rated cables are designed to be used in spaces with air circulation, such as above ceilings, because they have a fire-resistant jacket that minimizes the risk of toxic smoke in case of a fire. Coaxial, Shielded twisted pair, and Fiber optic cables do not possess the same fire safety ratings for plenum spaces, making them unsuitable for installation in these areas.
