Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 88

An IT team is growing quickly and needs a solution for management device access. The solution must authenticate users from an external repository instead of the current local on the WLC, and it must also identify the user and determine what level of access users should have. Which protocol do you recommend to achieve these goals?

Answer options

• A. network policy server
• B. RADIUS
• C. TACACS+
• D. LDAP

Correct answer: C

Explanation

TACACS+ is the most suitable protocol for this scenario as it provides detailed control over user authentication and authorization, allowing for granular access management. RADIUS is less flexible in terms of command authorization, while LDAP is primarily focused on directory services and does not handle access level determination as well as TACACS+. A network policy server, while useful, is not a protocol in the same context as the others listed.
