For SnapMirror Synchronous to operate across clusters, which licenses must be present on both clusters?

• A. SnapMirror license only
• B. SnapMirror Synchronous license only
• C. Both SnapMirror license and SnapMirror Synchronous license
• D. No licenses required

Answer: (C)

Cross-cluster SnapMirror Synchronous needs both licenses on every cluster because it builds on the base SnapMirror capability and adds the synchronous replication functionality. The SnapMirror license provides the core replication framework, while the SnapMirror Synchronous license enables the zero‑RPO, synchronous mode. Licensing is enforced per cluster, so each cluster must have both licenses installed to establish and run a synchronous replication link between them. Without the base SnapMirror license, the feature won’t be available; without the Synchronous license, synchronous replication cannot operate, even if SnapMirror is present.
