HPE Aruba Certified Switching Expert (ACSX) — Question 49

During a web login authentication, what is expected to happen as part of the Automated NAS login?

Answer options

• A. NAD sends TACACS+ request to ClearPass.
• B. ClearPass sends TACACS+ request to NAD.
• C. Client device sends RADIUS request to NAD.
• D. NAD sends RADIUS request to ClearPass.
• E. ClearPass sends RADIUS request to NAD.

Correct answer: D

Explanation

The correct answer is D because during the Automated NAS login, the Network Access Device (NAD) initiates a RADIUS request to ClearPass for authentication. Options A and B involve TACACS+, which is not used in this scenario, while options C and E incorrectly suggest the client device or ClearPass is initiating the RADIUS request.
