Refer to the exhibit.
A network administrator successfully creates a region on a controller team. Switch1 is part of this region. In the region, controllers are listed in this priority order: Controller 6, Controller 8, Controller 5.
The exhibit shows the controller information on Switch1.
The switch loses its connection to Controllers 6 and 8.
What happens?
A. Controller 6 communicates with other controllers to determine which of them have connectivity with the switch. Controller 5 advertises itself as the master for this switch.
B. Controller operations are suspended. Switch1 enters a failover mode, in which it continues to use existing flow entries but does not accept new ones, until it can reach at least two controllers.
C. Switch1 selects Controller 8 as its new master. After a timeout period, Switch1 selects Controller 5 as its master.
D. Switch1 temporarily enters a failover mode, in which it continues to use existing flow entries but does not accept new ones. After a timeout period, it contacts first Controller 8, and then Controller 5.
