HPE Aruba Certified Design Expert (ACDX) — Question 48

An Aruba Mobility Master (MM)-based solution has a WLAN that uses WPA2-Enterprise security. A test login on a wireless client fails.
How can a network administrator determine whether the RADIUS server rejected the credentials or another issue occurred?

Answer options

• A. Use the tools in the MM Dashboard > Security window.
• B. Use the MC AAA Server Test Diagnostic tool.
• C. Ping the IP address configured as the RADIUS server.
• D. View Technical Support information for the MM.

Correct answer: B

Explanation

The correct answer is B because the MC AAA Server Test Diagnostic tool specifically tests the connection to the RADIUS server and can determine if the credentials were rejected. Option A does not directly diagnose the issue with RADIUS, option C only checks connectivity, and option D does not provide specific information about authentication failures.
