RADIUS provides which two services in network access control?

• A. Authorization and Auditing
• B. Authentication and Accounting
• C. Encryption and Integrity
• D. Data Privacy and Logging

Answer: (B)

RADIUS is a AAA protocol used in network access control. Its main role is to verify a user or device’s identity (authentication) when they try to connect, and to record details of their session for monitoring and billing purposes (accounting). When authentication succeeds, the RADIUS server can supply attributes that help authorize what the user is allowed to do (like VLAN assignment or access rights), but the two core services are authentication and accounting. The other options describe capabilities like encryption or privacy, which aren’t the primary services provided by RADIUS, and while logging can be part of accounting, the essential pairing is authentication and accounting.
