Explanation

This question tests knowledge of WLC technologies that reduce roaming latency by speeding up re-authentication and key negotiation between clients and access points.

Common mistakes.

B. 802.11v provides BSS Transition Management to recommend roaming candidates to clients, but it does not accelerate the authentication process itself.
D. 802.1X is a port-based Network Access Control framework used for initial authentication, not for reducing roaming latency between APs.
E. WPA2 is a security certification based on 802.11i that defines encryption and authentication standards but provides no mechanism to enhance or accelerate roaming.

Concept tested. WLC fast roaming technologies CCKM and 802.11r
