CompTIA Network+ (N10-008) — Question 394

A network engineer is designing a wireless network that has the following requirements:

• Network speed must be higher than 100Mbps
• Must use the 2.4GHz and 5GHz bands

Which of the following 802.11 standards should the engineer select?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, 802.11n, as it supports speeds greater than 100Mbps and operates on both 2.4GHz and 5GHz bands. Options A (802.11a) and C (802.11g) do not meet the speed requirement, while option B (802.11b) is limited to lower speeds and only operates on the 2.4GHz band.
