What must be configured in clustered ONTAP 8.2 to support inter-cluster Snapmirror relationships? (choose all that apply)
The correct answer is A. Cluster peering relationship E. Vserver 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.

Why each option
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.
A cluster peering relationship must be established between the source and destination clusters using the 'cluster peer create' command, which authenticates the clusters and enables secure communication over intercluster LIFs. Without this relationship, the clusters cannot identify or trust each other, making any cross-cluster SnapMirror replication impossible.
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.
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.
Minimum transfer size is not a required configuration element for establishing or operating inter-cluster SnapMirror relationships in ONTAP 8.2.
A vserver peering relationship must also be created between the source and destination vservers using 'vserver peer create', which explicitly authorizes data transfer between specific vservers on already-peered clusters. This peering defines the permitted scope of replication and which protocols are allowed, and is a required step before creating a SnapMirror relationship between vserver volumes.
