What does Extensible Authentication Protocol (EAP) primarily provide?

• A. A browser plugin
• B. Centralized authentication and authorization management system
• C. A hardware device
• D. A wireless encryption standard

Answer: (B)

EAP is an authentication framework that provides a flexible way for a client and an authentication server to negotiate and carry out authentication for network access. It doesn’t supply credentials itself or be a standalone device; instead, it supports multiple methods (such as certificate-based, token-based, or password-based approaches) that can be used to verify a user or device. In enterprise and WLAN VPN setups, EAP works with a central authentication server (like RADIUS or TACACS+) to perform the actual verification and to enforce authorization decisions. Because of that, EAP enables centralized authentication and authorization management, rather than being a browser plugin, a hardware device, or a wireless encryption standard. The security and trust come from the chosen EAP method and the backend server, which coordinate to validate credentials and grant access.
