HPE Aruba Certified Design Expert (ACDX) — Question 44

Which IEEE standard provides the highest transmission rates in the 2.4GHz frequency band?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, 802.11n, which supports higher data rates and can operate in both the 2.4GHz and 5GHz bands. Options A and B are incorrect because 802.11a operates only in the 5GHz band, while 802.11ac exclusively operates in the 5GHz band as well, and 802.11g, while faster than 802.11a, does not reach the speeds of 802.11n.
