CompTIA A+ Core 1 (220-1001) — Question 328

When installing three 2.4GHz access points in close proximity, which of the following channel selections would be BEST?

Answer options

• A. 1, 6, 11
• B. 2, 3, 9
• C. 2, 4, 7
• D. 8, 10, 11

Correct answer: A

Explanation

The best choice is A (1, 6, 11) because these channels are non-overlapping in the 2.4GHz band, minimizing interference. The other options (B, C, D) include channels that overlap, which can lead to signal degradation and reduced performance due to interference between the access points.
