What wireless encryption technology utilizes EAP or RADIUS for centralized authentication?

1. WPA2-Personal

2. WPA2-Enterprise

3. WEP

4. WPA3-Personal

The correct answer is: WPA2-Enterprise

WPA2-Enterprise is the correct choice because it specifically employs Extensible Authentication Protocol (EAP) in conjunction with RADIUS (Remote Authentication Dial-In User Service) for centralized authentication. This technology allows organizations to manage and authenticate users more effectively by implementing a robust framework for secure communications. In a WPA2-Enterprise setup, authentication requests are sent to a RADIUS server, which verifies the credentials of the user. This model is particularly beneficial for larger networks where user management and security are paramount, as it provides unique credentials for individual users rather than a shared passphrase. The other options, like WPA2-Personal and WPA3-Personal, are designed for smaller networks and typically utilize a pre-shared key (PSK) for authentication rather than centralized methods like EAP and RADIUS. WEP is largely outdated and provides inadequate security compared to WPA2 and WPA3, lacking the centralized authentication capabilities provided by RADIUS. Therefore, WPA2-Enterprise stands out as the definitive choice for environments that require strong, centralized authentication.
