CompTIA Network+ (N10-009) — Question 28

Which of the following network cables involves bouncing light off of protective cladding?

Answer options

• A. Twinaxial
• B. Coaxial
• C. Single-mode
• D. Multimode

Correct answer: D

Explanation

The correct answer is D, Multimode, as it uses multiple light paths and reflects light off the cladding to transmit data. A, Twinaxial, and B, Coaxial, are copper cables that do not employ light for transmission, while C, Single-mode, uses a single light path and does not involve bouncing light off cladding in the same way as Multimode.
