Which NetApp solution provides metro-scale disaster recovery over IP?

• A. SnapMirror
• B. SnapMirror Synchronous
• C. FabricPool
• D. MetroCluster over IP

Answer: (D)

MetroCluster over IP is built to deliver disaster recovery across two sites connected over IP networks, with a shared storage namespace and coordinated failover. It uses synchronous replication between the two NetApp clusters and automatic failover/failback, so applications can continue to access data with minimal interruption even if one site experiences an outage. This specifically targets metro-scale disaster recovery over IP, which is exactly what the question asks for. The other options serve different purposes: SnapMirror is primarily replication (often asynchronous) between systems, SnapMirror Synchronous focuses on near-site synchronous replication but not the full metro-scale, namespace-continuity DR solution, and FabricPool handles cloud tiering rather than disaster recovery.
