CWAP: Certified Wireless Analysis Professional v402 — Question 11

You are responsible for troubleshooting and analysis of the WLAN in your organization that supports more than 700 client STAs. Forty APs are deployed and they are all dual-band APs and are controller-based. You must troubleshoot the wired side in some scenarios using a protocol analyzer.
Which one of the following problems would warrant wired-side analysis in most situations?

Answer options

• A. High 802.11 retry rates
• B. High 802.11 CRC rates
• C. WMM QoS issues
• D. DHCP problems

Correct answer: C

Explanation

WMM QoS issues often stem from problems in the wired network, as they affect how traffic is prioritized and managed. High retry rates and CRC rates are typically indicative of wireless issues, while DHCP problems can often be diagnosed without needing to analyze the wired network. Therefore, WMM QoS issues are the most relevant for wired-side analysis.
