Be careful this question is about AP failover and priority , so we dont need to have controller in same subnet. in the context of HA (High Availability) and SSO yes we should have controllers Management IP in same subnet.

A is false as CAPWAP establishment has nothing to do with mobility B is possible a correct answer as this is a per AP setting which could mean the AP's IP were configured incorrectly on some AP's giving the result of some working while others dont. C is false as the high availability setting uses IP for function and one can set the names to whatever one wishes without loss of function D is absolutely the correct answer as failover priority is used when there are to many AP's and some should have priority over others. And there is no reason to mention "sufficient licenses" unless its to indicate to many AP's.

Selected Answer: B

The controllers do not have to be in the same mobility group. Priority is not the issue here either. In the guides, you will not find any references about DNS in the HA configuration. I would suggest answer B in this case. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/m_configuring_backup_controllers.pdf

If the secondary WLC IP is wrong, why should only "some" APs not failover? If the secondary IP is wrong, the failover shouldnt work for all APs .. or am i misunderstanding something here?
