Question
What must be configured to support cross-cluster SnapMirror relationships?
Options
- Acluster peer relationship
- Bintracluster port
- Cjunction path
- Dminimum transfer size
Explanation
Cross-cluster SnapMirror requires a cluster peer relationship to authenticate and establish connectivity between the source and destination clusters before replication can occur.
Common mistakes.
- B. 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.
- C. 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.
- D. Minimum transfer size is not a configurable prerequisite for SnapMirror - it is not a required setting to enable cross-cluster replication.
