Which copper-based cable supports up to 1 Gbps at 100 meters?

• A. 1000BASE-LX
• B. 802.11a
• C. Cat6
• D. Cat5e

Answer: (D)

Gigabit Ethernet over copper is achieved with 1000BASE-T, which runs at 1 Gbps over twisted-pair cables up to 100 meters. Cat5e is the standard copper cabling that reliably supports that speed at the full 100-meter distance, providing the necessary bandwidth and signal integrity for 1000BASE-T. The other options don’t fit as well: 802.11a is a wireless standard, not copper cabling. 1000BASE-LX is fiber, not copper. Cat6 can also carry 1 Gbps at 100 meters, but the question asks for a copper-based cable that supports that speed, and Cat5e is the classic, widely deployed choice that meets the requirement.
