Which two cable types can support 10Gbps speed? (Choose two.)

The correct answer is A. CAT7 D. CAT6a. Among standard copper Ethernet cable categories, CAT6a and CAT7 are the two types rated to reliably carry 10Gbps traffic, while lower categories max out at 1Gbps or less.

Why each option

Among standard copper Ethernet cable categories, CAT6a and CAT7 are the two types rated to reliably carry 10Gbps traffic, while lower categories max out at 1Gbps or less.

ACAT7Correct

CAT7 is rated for 10Gbps and higher at frequencies up to 600 MHz, with fully shielded twisted pairs that exceed the 10GBASE-T requirements.

BCAT5a

CAT5a is not a recognized TIA/EIA or ISO/IEC cabling standard; it is a non-existent category designation.

CCAT5e

CAT5e is rated for 1000BASE-T (1Gbps) and does not have sufficient bandwidth headroom to support 10Gbps over structured cabling runs.

DCAT6aCorrect

CAT6a (Augmented Category 6) is the minimum standard defined by TIA-568-C.2 to support 10GBASE-T at full 100-meter runs, operating at up to 500 MHz.

ECAT5

CAT5 is rated for a maximum of 100Mbps (100BASE-TX) and cannot support 10Gbps transmission.
