CCNA: Cisco Certified Network Associate — Question 1184

Which design element is a best practice when deploying an 802.11b wireless infrastructure?

Answer options

• A. allocating nonoverlapping channels to access points that are in close physical proximity to one another
• B. disabling TCP so that access points can negotiate signal levels with their attached wireless devices
• C. configuring access points to provide clients with a maximum of 5 Mbps
• D. setting the maximum data rate to 54 Mbps on the Cisco Wireless LAN Controller

Correct answer: A

Explanation

The correct answer, A, highlights the importance of using nonoverlapping channels for access points that are physically close to reduce interference and improve performance. Answer B is incorrect because disabling TCP would hinder communication rather than enhance it. Option C is not ideal as limiting clients to 5 Mbps does not utilize the capabilities of the 802.11b standard effectively. Lastly, D is incorrect since 802.11b has a maximum data rate of 11 Mbps, and configuring it to 54 Mbps is not applicable.
