In a scenario where zero RPO/RTO is required with integrated backups, which solution best meets these requirements?

• A. SnapMirror active sync with SnapCenter
• B. SnapVault with SnapLock
• C. MetroCluster IP
• D. SnapMirror asynchronous

Answer: (A)

Focusing on zero RPO and zero RTO means you need data being kept up-to-date at a remote site and backups that are ready to restore without delay. Synchronous replication is what delivers zero RPO because every write is durably recorded at both the primary and the destination before the write is acknowledged. When you pair that with SnapCenter, backups are integrated and automated across those same data copies, so you have consistent, ready-to-restore backups that align with the live data. This combination provides the strongest protection for immediate recovery while keeping backups synchronized, which is why it best meets the requirement. The other options don’t offer the same guarantees. A backup approach that relies on asynchronous replication can’t promise zero RPO. A MetroCluster setup provides high availability and rapid failover but isn’t inherently about integrated backups in the same way, and it’s a larger, more complex DR solution. An asynchronous SnapMirror path won’t deliver zero RPO either.
