Which method of wireless authentication can take advantage of identity verification using a Radius server?

• A. WEP
• B. WPA
• C. WPA2-Enterprise
• D. WPA3-Personal

Answer: (C)

Centralized authentication for wireless networks uses 802.1X and a RADIUS server. In this setup, the access point acts as an entry point, passing credentials from the client to the RADIUS server, which verifies identity against a directory (like Active Directory) using an appropriate EAP method. This per-user verification and policy enforcement is what makes enterprise-grade authentication possible. Among the options, the one that supports this identity-based verification through a RADIUS server is the enterprise version of WPA2. It operates with 802.1X/EAP, enabling each user or device to be authenticated separately against a directory via RADIUS. The other options rely on a pre-shared key or are insecure legacy protocols, so they don’t leverage a RADIUS-based identity check.
