Suggested answer: B

Explanation:

For ClusterXL to work properly, one of the mandatory requirements is that theMagic MAC numbermust be unique per cluster node. The Magic MAC number is a MAC address that is used by ClusterXL to hide the physical MAC addresses of the cluster members from the network. This way, the cluster can present a single virtual MAC address to the network, and avoid ARP issues when a failover occurs. The Magic MAC number is derived from the Cluster Virtual IP address, which must also be unique per cluster.
