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.
