Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 166

During a meeting to gather the requirements for a new Wi-Fi network design, the customer requests that 802.11a and 802.11ac clients be able to connect. Which affect does this have to the wireless network?

Answer options

• A. bigger channel width
• B. lower throughput
• C. 2.4 GHz signal congestion
• D. higher RF reflection

Correct answer: B

Explanation

The correct answer is B because 802.11a operates on the 5 GHz band which can lead to reduced throughput when mixed with 802.11ac clients that may be optimized for higher speeds. The other options do not accurately reflect the implications of connecting these two standards; for instance, channel width does not inherently decrease, and RF reflection is not directly related to client compatibility.
