Which feature intersection of a Cisco 5760 Wireless LAN Controller with HA AP SSO is not true?

Which feature intersection of a Cisco 5760 Wireless LAN Controller with HA AP SSO is not true?
A . Upon guest anchor controller switchover, mobility tunnels stay active, APs remain connected, clients rejoin at MA or MC, and clients are anchored on the new active controller.
B . wIPS information is synced to the standby unit. The standby unit does not have to relearn wIPS information upon switchover.
C . Roamed clients that have their data path going through the mobility tunnel endpoint “become Local” in case of Layer 2 with sticky anchoring and Layer 3 roam. Layer 2 roamed clients are not affected except when roaming occurs between Cisco Unified Wireless Network and CA controllers.
D . Switchover during AP preimage download causes the Aps to start image download all over again from the new active controller.

Answer: B

Explanation:

– Switchover during AP Pre-Image download causes the APs to start image download all over again from the new Active controller.

– Rogue APs and clients are not synced to Standby and are re-learnt upon switchover.

– Infrastructure MFP key is not synced to the Standby controller and is re-learnt upon switchover.

– New Active controller re-learns the shun list from IPS and other MCs, and redistributes it to the MAs.

– wIPS information is not synced to the Standby unit and is re-learnt upon switchover.

– Clean Air detected Interferer devices are re-learnt after switchover.

– Net Flow records are cleared upon switchover and collection starts fresh on the new Active controller.

– Mobility paths and tunnels to the MO and other peer MCs are not disrupted upon switchover. However the Client state is cleaned up on the MO under which the HA pair exists and is re-learnt from the new Active controller when the client re-associates.

– Roamed clients that have their data path going through the Mobility Tunnel Endpoint (MTE) “become Local” in case of L2 with Sticky Anchoring and L3 Roam. L2 Roamed Clients are not affected except when roaming occurs between CUWN and CA controllers.

– RRM related configurations and the AP neighbor list in the Leader HA pair is synced to the Standby controller.

– Upon Guest Anchor controller switchover, mobility tunnels stay active, APs remain connected, clients rejoin at MA or MC, and are anchored on the new Active controller.
