CCNA: Cisco Certified Network Associate — Question 1306

Which protocol must be implemented to support separate authorization and authentication solutions for wireless APs?

Answer options

• A. RADIUS
• B. TACACS+
• C. 802.1X
• D. Kerberos

Correct answer: B

Explanation

TACACS+ is the correct answer because it provides separate handling of authentication and authorization, making it suitable for environments that require distinct solutions for wireless access points. RADIUS, while similar, does not separate these functions as effectively. 802.1X is a port-based network access control protocol, and Kerberos is primarily an authentication protocol, thus not addressing the need for separate authorization solutions.
