CompTIA Network+ (N10-009) — Question 387

A network engineer needs to order cabling to connect two buildings within the same city. Which of the following media types should the network engineer use?

Answer options

• A. Coaxial
• B. Twinaxial
• C. Single-mode fiber
• D. Cat 5

Correct answer: C

Explanation

The correct answer is C, Single-mode fiber, as it is ideal for long-distance communication between buildings due to its high bandwidth and low attenuation. The other options, such as Coaxial, Twinaxial, and Cat 5, are not suitable for such distances and would result in signal degradation.
