Suggested answer: C

Explanation:

The HA topology shown in the exhibit is using link monitoring with two heartbeat interfaces (port3 and port5) and a heartbeat interval of 100ms. Link monitoring is a feature that allows HA failover to occur when one or more monitored interfaces fail or become disconnected. The heartbeat interval is the time between each heartbeat packet sent by an HA cluster unit to other cluster units through heartbeat interfaces. The failover time is determined by multiplying the heartbeat interval by three (the default deadtime value). Therefore, in this case, the failover time is 100ms x 3 = 300ms.
