CWAP: Certified Wireless Analysis Professional v402 — Question 14

You have been asked to recommend a solution for protocol capture of 802.11 frames consisting of 3x3:3 802.11ac communications. The requirement specifies that you gain a general view of a coverage area and does not require that you capture from specific user locations. The solution must be the least expensive practical solution possible that does not disrupt user access to the WLAN and it must be based on enterprise WLAN hardware.
What solution would you recommend so that any coverage area could be monitored on demand?

Answer options

• A. Install laptop-based protocol analyzer near each AP
• B. Install Wireshark on the Aps natively to allow dynamic capture while serving clients
• C. Install the minimum number of Aps required for coverage and use these Aps for protocol analysis as needed
• D. Install sufficient Aps so that an AP can be taken offline to perform protocol analysis as needed

Correct answer: B

Explanation

The correct answer is B because installing Wireshark on the APs allows for dynamic capture without interrupting client service, meeting the requirement for minimal disruption. Option A is not practical since it requires many laptops, which increases costs and complexity. Option C suggests using fewer APs, which could lead to insufficient coverage and missed data. Option D proposes taking an AP offline, which would disrupt user access, contradicting the requirement.
