CompTIA A+ Core 1 (220-1101) — Question 541

Which of the following standards supports MIMO technology?

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 was the first standard to implement MIMO technology, allowing for multiple input and output streams which enhance throughput and range. Options A, B, and C do not support MIMO; they utilize single antenna technology, which limits their performance compared to 802.11n.
