CWNA: Certified Wireless Network Administrator v107 — Question 18

In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping?

Answer options

• A. 11 and 6
• B. 7 and 11
• C. 1 and 5
• D. 2 and 8

Correct answer: A

Explanation

The non-overlapping channels in the 2.4 GHz band are 1, 6, and 11. Channels 11 and 6 are spaced far enough apart to avoid interference, while the other options either include overlapping channels or do not include both of the correct non-overlapping channels.
