MetroCluster provides which capability?

• A. Asynchronous replication only
• B. Zero RPO and automated site failover
• C. Cloud-only deployment
• D. Synchronous mirroring with zero RPO

Answer: (C)

MetroCluster is about keeping data available across two sites by mirroring writes in real time and switching over automatically if a site fails. Because the data is written to both sites before the operation is acknowledged, you achieve zero RPO. Automated site failover means services resume at the surviving site with no manual intervention, maintaining continuous availability. Cloud-only deployment isn’t how MetroCluster is used; it’s a two-site disaster-recovery solution typically deployed across separate data centers (often connected by high-speed links). The key capability is synchronous mirroring with automatic failover, yielding zero data loss and fast disaster recovery.
