CCNA: Cisco Certified Network Associate — Question 286

What is a recommended approach to avoid co-channel congestion while installing access points that use the 2.4 GHz frequency?

Answer options

• A. different nonoverlapping channels
• B. one overlapping channel
• C. one nonoverlapping channel
• D. different overlapping channels

Correct answer: A

Explanation

Choosing different nonoverlapping channels helps to minimize co-channel congestion, allowing for better performance and reduced interference. Using one overlapping channel or different overlapping channels can lead to increased interference and degraded network performance. A single nonoverlapping channel does not provide enough diversity to avoid congestion across multiple access points.
