SnapVault backup between two different clustered Data ONTAP 8.2 or later systems requires what type of intercluster communication?

Options

ACluster Vaulting LIFs for intercluster communication
BCluster Replication LIFs for intercluster communication
CCluster Peering LIFs for intercluster communication
DCluster Backup LIFs for intercluster communication

Explanation

SnapVault between two clustered Data ONTAP 8.2 systems requires cluster peering LIFs - dedicated intercluster LIFs that establish the peer relationship enabling cross-cluster data replication.

Common mistakes.

A. Cluster Vaulting LIFs is not a valid LIF role or type in clustered Data ONTAP 8.2.
B. Cluster Replication LIFs is not a recognized LIF role in Data ONTAP; the correct role is intercluster, used for peering.
