Exam 300-430 topic 1 question 136 discussion

TACACS+ (Terminal Access Controller Access-Control System Plus): TACACS+ is specifically designed for device administration and provides detailed authorization and accounting capabilities. It authenticates users against an external repository and can determine the level of access (authorization) based on user roles. It is ideal for managing access to network devices, such as WLCs, and supports granular control over commands and permissions. Why not the other options? A. Network Policy Server (NPS): NPS is a Microsoft implementation of RADIUS and is primarily used for network access control, not device administration. B. RADIUS (Remote Authentication Dial-In User Service): RADIUS is more suited for network access authentication (e.g., wireless or VPN) and lacks the granular authorization capabilities of TACACS+. D. LDAP (Lightweight Directory Access Protocol): LDAP is used for directory services and user authentication but does not provide the same level of granular authorization for device access as TACACS+.

C for sure!
