Which of the following twisted pair cables supports 10GBASE-T data transmission speed?
The correct answer is D. Cat 6a. Cat 6a (Category 6 Augmented) is the minimum cable standard required to support 10GBASE-T (10 Gigabit Ethernet) at the full standard distance of 100 meters. Cat 6 can support 10GbE but only at reduced distances (up to ~55 meters). Cat 5e (C) tops out at 1 Gbps (1000BASE-T). Cat 5

Explanation
Cat 6a (Category 6 Augmented) is the minimum cable standard required to support 10GBASE-T (10 Gigabit Ethernet) at the full standard distance of 100 meters. Cat 6 can support 10GbE but only at reduced distances (up to ~55 meters). Cat 5e (C) tops out at 1 Gbps (1000BASE-T). Cat 5 (B) supports up to 100 Mbps (100BASE-TX). Cat 3 (A) supports only up to 10 Mbps and is largely obsolete. For exam purposes: Cat 6a = 10 Gbps at 100m is a key fact to memorize.
