CWNA: Certified Wireless Network Administrator v107 — Question 25

The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both 2.4 GHz and 5 GHz. What is the least expensive solution available for increasing throughput for these users without implementing configuration options that are not recommended?

Answer options

• A. Use a 160 MHz channel on the 5 GHz radio
• B. Use a 40 MHz channel on the 5 GHz radio
• C. Install a second AP in the coverage area
• D. Use a 40 MHz channel on the 2.4 GHz radio

Correct answer: C

Explanation

The correct answer is C because adding a second AP increases the available bandwidth and allows more devices to connect simultaneously, thus improving throughput. Options A and B may offer higher throughput but could face interference issues and are not the least expensive solution. Option D is not ideal since the 2.4 GHz band has fewer channels and is more prone to congestion.
