What drawbacks initially prevented the widespread acceptance and use of Opportunistic Key Caching (OKC)? 

What EAP type supports using MS-CHAPv2, EAP-GTC or EAP-TLS for wireless client authentication? 

Given: You are the WLAN administrator in your organization and you are required to monitor the network and ensure all active WLANs are providing RSNs. You have a laptop protocol analyzer configured. In what frame could you see the existence or non-existence of proper RSN configuration parameters for each BSS through the RSN IE?

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.)
