CompTIA Network+ (N10-009) — Question 133

Which of the following cable types provides the highest possible transmission speed?

Answer options

• A. Plenum
• B. Ethernet
• C. Fiber-optic
• D. DAC

Correct answer: C

Explanation

Fiber-optic cables are known for their ability to transmit data at extremely high speeds over long distances due to the use of light. In contrast, Plenum, Ethernet, and DAC cables do not match the speed capabilities of fiber-optic technology, making them less suitable for high-speed data transmission.
