CompTIA Network+ (N10-008) — Question 254

A network administrator is planning a WLAN for a soccer stadium and was advised to use MU-MIMO to improve connection performance in high-density areas.
The project requires compatibility with clients connecting using 2.4GHz or 5GHz frequencies. Which of the following would be the BEST wireless standard for this project?

Answer options

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

Correct answer: B

Explanation

The correct answer is 802.11ax, as it supports MU-MIMO technology and operates on both 2.4GHz and 5GHz frequencies, making it ideal for high-density environments. 802.11ac, while fast, primarily operates on 5GHz and lacks the same level of efficiency in crowded settings. 802.11n supports both frequencies but does not offer the advanced features of MU-MIMO found in 802.11ax, and 802.11g is outdated and not suitable for modern high-density applications.
