CompTIA Network+ (N10-008) — Question 705

Which of the following copper wire standards utilizes four pairs of wires to achieve Gigabit Ethernet speeds?

Answer options

• A. 1000BASE-FX
• B. 1000BASE-T
• C. 1000BASE.LR
• D. 1000BASE-SX

Correct answer: B

Explanation

The correct answer is 1000BASE-T, as it specifically uses four pairs of twisted copper wires to support Gigabit Ethernet speeds. The other options, such as 1000BASE-FX, 1000BASE.LR, and 1000BASE-SX, are fiber optic standards and do not utilize copper wiring.
