200-301 Question #493: Real Exam Question with Answer & Explanation

Question

What are two similarities between UTP Cat 5e and Cat 6a cabling? (Choose two.)

Options

• ABoth operate at a frequency of 500 MHz.
• BBoth support runs of up to 55 meters.
• CBoth support runs of up to 100 meters.
• DBoth support speeds of at least 1 Gigabit.
• EBoth support speeds up to 10 Gigabit.

Explanation

Cat 5e and Cat 6a cables both support maximum runs of 100 meters and speeds of at least 1 Gigabit Ethernet.

Common mistakes.

• A. Cat 5e operates at up to 100 MHz, while Cat 6a operates at up to 500 MHz, so they do not both operate at 500 MHz.
• B. Both Cat 5e and Cat 6a support runs of up to 100 meters, not 55 meters, for their standard maximum lengths.
• E. Cat 5e cables only reliably support speeds up to 1 Gigabit, not 10 Gigabit, making this statement incorrect for Cat 5e.
