CWDP: Certified Wireless Design Professional v303 — Question 7

When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?

Answer options

• A. Frequency Selection
• B. Roaming
• C. AP vendor
• D. Band steering

Correct answer: A

Explanation

Frequency Selection is crucial for optimizing the performance of voice over WLAN, as it directly impacts the available bandwidth and interference levels. While Roaming, AP vendor, and Band steering are also important components of WLAN design, they do not have as direct an effect on performance for voice applications compared to the careful selection of frequency channels.
