CCNA: Cisco Certified Network Associate — Question 646

What is the role of nonoverlapping channels in a wireless environment?

Answer options

• A. to increase bandwidth
• B. to stabilize the RF environment
• C. to allow for channel bonding
• D. to reduce interference

Correct answer: D

Explanation

The correct answer is D because nonoverlapping channels help to minimize interference between signals, allowing for clearer communication. Options A, B, and C do not accurately describe the primary purpose of nonoverlapping channels, which focuses on reducing interference rather than increasing bandwidth, stabilizing the RF environment, or enabling channel bonding.
