CompTIA Network+ (N10-007) — Question 450

A network engineer needs to connect two network switches with a gigabit link. The proposed route to run the 164ft (50m) cable is directly underneath a large electrical generator. Which of the following cable types would BEST fit the needs of the network engineer?

Answer options

• A. UTP
• B. Cat 5 plenum
• C. Coaxial
• D. STP

Correct answer: D

Explanation

The correct answer is D, STP (Shielded Twisted Pair), because it provides better protection against electromagnetic interference, which is likely from the nearby electrical generator. UTP (Option A) is more susceptible to interference, while Cat 5 plenum (Option B) and Coaxial (Option C) do not offer the same level of shielding required in this scenario.
