CompTIA A+ Core 1 (220-1001) — Question 406

Which of the following IEEE 802.11 standards includes the use of 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 is the first standard to utilize MIMO (Multiple Input Multiple Output) technology, which significantly enhances wireless performance. The other standards, 802.11a, 802.11b, and 802.11g, do not support MIMO and therefore lack the advanced capabilities provided by this technology.
