It is : D. IPSec
There are two major components to MM redundancy:
•VRRP IP—This IP address is shared between the active (primary) and standby MM. MCs terminating on the active MM should point to this IP address. Thus, in the event of an MM outage, they will failover to the standby MM.
•Configuration and database synchronization—An IPsec tunnel forms between the two MMs to synchronize configuration and databases.
It’s D
An IPsec tunnel is set up between the two MMs, to synchronize configuration and databases.
