CCNA: Cisco Certified Network Associate — Question 392

Which service is missing when RADIUS is selected to provide management access to the WLC?

Answer options

• A. authorization
• B. authentication
• C. accounting
• D. confidentiality

Correct answer: D

Explanation

The correct answer is D, confidentiality, because RADIUS primarily focuses on authentication, authorization, and accounting, but it does not provide confidentiality of the information being transmitted. Options A, B, and C are all services that RADIUS handles effectively, making them incorrect in this context.
