CompTIA A+ Core 1 (220-1201) — Question 24

Which of the following should be used when installing network cabling above a drop ceiling that is part of the shared air space?

Answer options

Correct answer: B

Explanation

Plenum-rated cable is designed to be used in spaces that facilitate air circulation for heating and air conditioning, as it has a low smoke and flame rating. The other options, while useful in different applications, do not meet the safety requirements necessary for use in plenum spaces and could pose fire hazards.
