A- even the RP is down. RMI can be UP, so the peer connectivity will be checked over network infrastructure . in that time Standy will go to maintainance mode
B - still RP is active and peer can be seem .
C- this will cause switches to have split brain cause WLC to do the same since RP, RMI all are down.
its a LAG , so two or more can be aggregated . here one port down wont disconnect any connectivities.
C should be right.
According to: https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-7/High_Availability_DG.html 'network issues' diagramm
A: Standby will reboot
B: no action
D: no action
When VSL gets cut, switches might go into split brain, which cuts RP Link aswell as some connectivity of wlcs so they might also go into split brain.
