CompTIA Network+ (N10-009) — Question 27

A network administrator is performing a refresh of a wireless environment. As the APs are being placed, they overlap a little bit with each other. Which of the following 2.4GHz channels should be selected to ensure that they do not conflict?

Answer options

• A. 1, 3, 5
• B. 1, 6, 11
• C. 2, 6, 10
• D. 3, 6, 9

Correct answer: B

Explanation

The correct choice is B, as channels 1, 6, and 11 are the only channels in the 2.4GHz spectrum that do not overlap and provide the best separation to minimize interference. Options A and D feature overlapping channels which can cause signal issues, while option C includes channel 2, which also overlaps with channel 1.
