You are using a protocol analyzer for random checks of activity on the WLAN. In the process, you notice two different EAP authentication processes. One process (STA1) used seven EAP frames (excluding ACK frames) before the 4-way handshake and the other (STA2) used 11 EAP frames (excluding ACK frames) before the 4-way handshake. Which statement explains why the frame exchange from one STA required more frames than the frame exchange from another STA when both authentications were successful? (Choose the single most probable answer given a stable WLAN.)
