NS0-157 Question #355: Real Exam Question with Answer & Explanation

The correct answer is A: Cluster peering relationship. Inter-cluster SnapMirror in clustered ONTAP 8.2 requires both a cluster peering relationship and a vserver peering relationship - cluster peering establishes trust between clusters, while vserver peering authorizes replication between specific vservers.

Question

What must be configured in clustered ONTAP 8.2 to support inter-cluster Snapmirror relationships? (choose all that apply)

Options

ACluster peering relationship
BIntercluster port role
CJunction path for the mirrored volume
DMinimum transfer size
EVserver peering relationship

Explanation

Inter-cluster SnapMirror in clustered ONTAP 8.2 requires both a cluster peering relationship and a vserver peering relationship - cluster peering establishes trust between clusters, while vserver peering authorizes replication between specific vservers.

Common mistakes.

B. While intercluster LIFs are needed for communication, 'intercluster port role' is not the correct configuration object in ONTAP 8.2 - intercluster LIFs are configured directly and do not require a separate port role assignment step.
C. A junction path defines NAS namespace mount points and is not a requirement for SnapMirror replication, which operates at the volume level independently of any NAS access configuration.
D. Minimum transfer size is not a required configuration element for establishing or operating inter-cluster SnapMirror relationships in ONTAP 8.2.

Concept tested. Cluster and vserver peering required for inter-cluster SnapMirror
