SK0-005 · Question #60
A server administrator is selecting cable for a 10GBASE-T server connection. If the server is 246ft (75m) from the switch, which of the following cable types should the administrator choose?
The correct answer is D. Cat 6a. For a 10GBASE-T server connection at 246 feet (75 meters), Cat 6a cable is the correct choice because it supports 10 Gbps speeds up to 100 meters, unlike Cat 6 which is limited to 55 meters.

Why each option
For a 10GBASE-T server connection at 246 feet (75 meters), Cat 6a cable is the correct choice because it supports 10 Gbps speeds up to 100 meters, unlike Cat 6 which is limited to 55 meters.
Cat 5 cable only supports speeds up to 100 Mbps and is entirely inadequate for 10 Gbps Ethernet.
Cat 5e cable supports speeds up to 1 Gbps but is insufficient for a 10 Gbps connection.
Cat 6 cable can support 10 Gbps, but only for distances up to 55 meters (180 feet), which is not sufficient for a 75-meter connection.
Cat 6a (Augmented Category 6) cable is specifically designed to support 10GBASE-T Ethernet connections at full 10 Gbps speeds over distances up to 100 meters (328 feet). Given the 75-meter (246 feet) distance, Cat 6a is required.
