What must be configured to support cross-cluster SnapMirror relationships?
The correct answer is A. cluster peer relationship. Cross-cluster SnapMirror requires a cluster peer relationship to authenticate and establish connectivity between the source and destination clusters before replication can occur.

Why each option
Cross-cluster SnapMirror requires a cluster peer relationship to authenticate and establish connectivity between the source and destination clusters before replication can occur.
A cluster peer relationship creates the authenticated, encrypted trust channel between two ONTAP clusters using intercluster LIFs and a shared passphrase. Without this peering, the destination cluster cannot accept SnapMirror replication requests from the source cluster, making it the foundational prerequisite for any cross-cluster SnapMirror configuration.
An 'intracluster port' is not a valid ONTAP concept for SnapMirror configuration - intercluster LIFs on intercluster ports are required, but the peer relationship itself is the prerequisite.
A junction path is used to mount volumes into the NAS namespace for client access and has no role in establishing or enabling SnapMirror replication between clusters.
Minimum transfer size is not a configurable prerequisite for SnapMirror - it is not a required setting to enable cross-cluster replication.
