Which feature provides centralized authentication, authorization, and accounting on Citrix ADC?

• A. ICA proxy
• B. Integrated caching
• C. AAA
• D. AppFlow

Answer: (C)

Centralized authentication, authorization, and accounting on Citrix ADC is handled by AAA. AAA brings together the processes of verifying who a user is (authentication), deciding what they are allowed to access (authorization), and recording access events for auditing (accounting). It can integrate with external identity stores like LDAP, RADIUS, SAML, or certificate-based methods, and you configure an AAA virtual server with authentication and authorization policies plus accounting logs to enforce and track access across Citrix ADC and Citrix Gateway sessions. This centralized control is what ensures consistent security and auditing for all access. ICA proxy is for proxied ICA traffic to remote apps, integrated caching speeds content delivery, and AppFlow is for traffic analytics and data export, not for centralized AAA.
