Exam RCWA Topic 5 Question 2 Discussion

SmartZone controllers support a range of external authentication services for both proxy (via controller) and non-proxy (direct-to-AAA) authentication mechanisms. According to the RUCKUS One Online Help - Authentication Services Configuration, the supported external services include:
Active Directory (AD) (A): Used for domain-based user authentication and group policy enforcement.
Lightweight Directory Access Protocol (LDAP) (B): Provides user authentication through directory lookup, commonly used for enterprise identity systems.
RADIUS (E): A widely used AAA protocol that integrates with external servers such as FreeRADIUS, Cisco ISE, or Microsoft NPS for centralized authentication and accounting.
While SAML and OAuth are used in RUCKUS Cloud and RUCKUS One for SSO (Single Sign-On) and API authentication, they are not used for WLAN or AAA authentication within SmartZone. TACACS+ is not supported as an external client authentication method in SmartZone (it is only used for admin login on some platforms).
Therefore, the correct authentication services are A (AD), B (LDAP), and E (RADIUS).
