CWAP: Certified Wireless Analysis Professional v402 — Question 13

You are troubleshooting throughput problems for a WLAN cell. The cell is provisioned with an 802.11ac dual-band AP. Users connected with both 5 GHz and 2.4
GHz connections are reporting performance problems. The AP settings are properly optimized. No interface issues have been detected (either co-channel interference or non-Wi-Fi interference) and the number of associated users is low.
What should you analyze to resolve the issue?

Answer options

• A. The 2.4 GHz radio configuration
• B. The antennas used on the client devices
• C. the Ethernet uplink and the network infrastructure
• D. The 5 GHz radio configuration

Correct answer: C

Explanation

The correct answer is C because the Ethernet uplink and network infrastructure can be a bottleneck affecting throughput, regardless of the wireless settings. Options A and D focus on radio configurations, which are already optimized, and option B addresses client devices, which are less likely to be the source of the problem given the context.
