A user is running a new video conferencing application on their laptop and is being disconnected as they move from one access point to another. Which situation will cause these disconnects?

The correct answer is B. FT is not supported by all clients. Fast Transition (FT), defined in IEEE 802.11r, significantly reduces the time required to reassociate when roaming between APs by pre-authenticating with the target AP. If FT is enabled on the WLAN but the client's wireless adapter does not support 802.11r, the client cannot…

Explanation

Fast Transition (FT), defined in IEEE 802.11r, significantly reduces the time required to reassociate when roaming between APs by pre-authenticating with the target AP. If FT is enabled on the WLAN but the client's wireless adapter does not support 802.11r, the client cannot complete the FT handshake and gets disconnected during the roam (B). This is a common issue with video conferencing applications that require continuous connectivity. P2P blocking (A) would prevent client-to-client traffic, not cause roaming disconnects. AAA override (C) is a policy feature unrelated to roaming continuity. Disabling WMM (D) would degrade QoS but not cause disconnections during AP transitions.
