Which protocol combines enterprise authentication with 802.1X and RADIUS?

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

Answer: (A)

Think about enterprise-grade wireless access: you don’t share a single password with everyone. Instead, each user or device authenticates through a central server, and access is controlled per user. 802.1X provides that framework for port-based access control, while RADIUS acts as the centralized authentication, authorization, and accounting server that verifies credentials (often via EAP methods like PEAP or EAP-TLS) and issues session keys. WPA2-Enterprise is the mode that brings these together on a wireless network: it uses 802.1X to authenticate to a RADIUS server and then establishes per-user encryption keys for secure communication. WEP is outdated and insecure, WPA (with a pre-shared key) doesn’t use per-user central authentication, and WPA3 is the newer standard (often in enterprise form), but the option that directly embodies enterprise authentication with 802.1X and RADIUS is WPA2-Enterprise.
