220-801 Question #1128: Real Exam Question with Answer & Explanation

The correct answer is D: CAT5e. CAT5e (Category 5 enhanced) supports speeds up to 1 Gbps (1000BASE-T Gigabit Ethernet) at distances up to 100 meters, making it the minimum standard for Gigabit networking. CAT6 supports up to 1 Gbps at 100 meters and up to 10 Gbps at shorter distances (up to ~55 meters), exceedi

Question

Which of the following cables can transmit Gigabit speeds? (Select TWO).

Options

ACAT3
BCAT4
CCAT5
DCAT5e
ECAT6

Explanation

CAT5e (Category 5 enhanced) supports speeds up to 1 Gbps (1000BASE-T Gigabit Ethernet) at distances up to 100 meters, making it the minimum standard for Gigabit networking. CAT6 supports up to 1 Gbps at 100 meters and up to 10 Gbps at shorter distances (up to ~55 meters), exceeding the Gigabit threshold. The other options fall short: CAT3 supports only 10 Mbps (used for older phone/10BASE-T networks), CAT4 supports 16 Mbps (used in older Token Ring networks), and standard CAT5 (without the 'e' enhancement) is rated for 100 Mbps (Fast Ethernet), not Gigabit speeds.
