The IEEE 802.

In WPA2-Enterprise:

After successful Open System authentication and 802.11 association, the next step is 802.1X/EAP authentication via EAPOL frames.

This phase establishes user identity and derives the PMK.

Incorrect:

A. Group Key Handshake comes after the 4-Way Handshake.

C. DHCP occurs after authentication and key negotiation.

D. 4-Way Handshake follows successful 802.1X authentication.

E. PSK mapping applies to WPA2-Personal, not Enterprise.

F. The RADIUS shared secret is pre-configured between authenticator and RADIUS server—not part of real-time negotiation.
