CompTIA Network+ (N10-007) — Question 290

A vendor is installing an Ethernet network in a new hospital wing. The cabling is primarily run above the celling grid near air conditioning ducts and sprinkler pipes.
Which of the following cable types is required for this installation?

Answer options

• A. Plenum
• B. PVC
• C. Single-mode
• D. Cat 7

Correct answer: A

Explanation

The correct answer is A, Plenum, because this type of cable is designed to be used in areas where there is a potential for fire and smoke to spread, as it has a fire-resistant jacket. The other options, such as PVC, do not meet the stringent fire safety requirements for plenum spaces, while Single-mode and Cat 7 refer to specific types of fiber and twisted pair cables, respectively, which are not relevant to the cabling material needed for the installation.
