CompTIA Network+ (N10-009) — Question 191

A small coffee shop wants to set up multiple 2.4GHz wireless access points. The access points will support a large number of users, and the network technician wants to mitigate interference as much as possible. Which of the following is the number of 22MHz channels that the equipment can support?

Answer options

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: C

Explanation

The correct answer is C, as the 2.4GHz band allows for a maximum of three non-overlapping 22MHz channels (1, 6, and 11) to minimize interference. Options A and B provide fewer channels than what is available, and option D exceeds the number of non-overlapping channels in the 2.4GHz spectrum.
