CompTIA Network+ (N10-008) — Question 758

A network consultant is installing a new wireless network with the following specifications:

5GHz
1,300Mbps
20/40/80MHZ

Which of the following standards should the network consultant use?

Answer options

• A. 802.11a
• B. 802.11ac
• C. 802.11b
• D. 802.11n

Correct answer: B

Explanation

The correct answer is B, 802.11ac, which supports the specified 5GHz frequency and can achieve throughput rates up to 1,300Mbps. The other options, 802.11a and 802.11n, do not support the same maximum speeds, and 802.11b operates on the 2.4GHz band, making it unsuitable for these requirements.
