CompTIA Network+ (N10-009) — Question 507

A company is installing network cables above the ceiling tiles. The cables must be fire rated. Which of the following cable types should the company use?

Answer options

• A. Coaxial
• B. Plenum
• C. Crossover
• D. STP

Correct answer: B

Explanation

The correct choice is Plenum cable, as it is specifically designed to meet fire safety standards for spaces like ceilings where air circulation occurs. Coaxial, Crossover, and STP cables do not have the same fire-resistant properties required for installation in plenum spaces.
