CompTIA Network+ (N10-007) — Question 57

An administrator is moving to a new office. There will be several network runs through the ceiling area of the office. Which of the following is the BEST to utilize in these areas?

Answer options

• A. Single-mode fiber-optic cabling
• B. Cat 5e-rated cabling
• C. Cat 6-rated cabling
• D. Plenum-rated cabling

Correct answer: D

Explanation

The correct answer is D, Plenum-rated cabling, as it is specifically designed to be installed in ceiling spaces that facilitate air circulation for heating and air conditioning systems. This type of cabling has a fire-resistant jacket that minimizes the risk of fire hazards in these areas. The other options, while useful for different networking scenarios, do not meet the necessary safety and regulatory requirements for plenum spaces.
