CompTIA Network+ (N10-007) — Question 649

A technician is planning a network wiring installation and must ensure all cabling meets the installation requirements for air-handling spaces in the celling in case of a fire. Which of the following characteristics does plenum cabling have to meet this requirement?

Answer options

• A. Outer jacket made of PVC
• B. Outer jacket with metal shielding
• C. Low-smoke material jacket
• D. Fiber-optic glass core

Correct answer: C

Explanation

Plenum cabling is required to have a low-smoke material jacket to minimize the release of harmful smoke and gases in the event of a fire, making option C correct. Options A and B do not provide the necessary fire safety characteristics, as PVC can emit toxic smoke, and metal shielding does not address smoke production. Option D, while relevant to fiber optics, does not pertain to the jacket material required for plenum spaces.
