CompTIA A+ 220-1202 Practice Question

It ensures users are authenticated, authorized, and monitored for network services. - This is correct. RADIUS (Remote Authentication Dial-In User Service) is a protocol used to authenticate and authorize users accessing network services, such as VPNs, Wi-Fi, or remote access servers. It also provides accounting by tracking usage details for auditing and monitoring purposes.

It provides encryption for transferred data during user sessions. - While RADIUS can work with protocols that provide encryption (e.g., WPA2 for wireless), its primary role is not encrypting data. Instead, it focuses on authentication, authorization, and accounting.

It manages the storage of user passwords in a database. - RADIUS does not store passwords itself; instead, it verifies credentials against a database or directory (like Active Directory or LDAP) as part of the authentication process.

It acts as a firewall to control unauthorized access to the network. - A firewall controls traffic flow and enforces security rules, which is different from RADIUS's focus on user authentication and authorization.
