Why each option
RADIUS is commonly used for authentication, authorization, and accounting (AAA), and it frequently integrates with EAP to secure authentication for wireless networks.
RADIUS servers are widely used in conjunction with Extensible Authentication Protocol (EAP) to provide robust authentication for users connecting to wireless networks, where the access point acts as a RADIUS client.
While RADIUS can support various authentication methods, its primary purpose is not encrypted multiprotocol support across the board; it's an authentication protocol.
In RADIUS, the password (or shared secret) is encrypted, but the entire device-administration packet (e.g., username, accounting information) is not encrypted; only specific attributes are.
RADIUS is used to authenticate and authorize users, directly linking activities to a user identity; therefore, it does not ensure user anonymity.
