CompTIA A+ Core 1 (220-1001) — Question 307

Which of the following types of cables is used to provide high-speed voice and data connections in a datacenter to Layer 3 devices?

Answer options

• A. HDMI
• B. Multimode fiber
• C. Thunderbolt
• D. SATA
• E. Cat 5

Correct answer: B

Explanation

The correct answer is B, Multimode fiber, as it is specifically designed for high-speed data transmission over short distances, making it ideal for datacenter environments. The other options, such as HDMI and Thunderbolt, are primarily used for video/audio connections and not for data networking, while SATA is used for connecting storage devices, and Cat 5 is an older standard that does not support the same speeds as multimode fiber.
