Which statement accurately describes MetroCluster's requirements?

• A. It provides asynchronous DR across multiple sites
• B. It requires only software licensing
• C. It relies on NAS-based replication
• D. It provides synchronous, site-to-site HA for zero data loss with two sites connected and required licensing

Answer: (D)

MetroCluster is built to deliver synchronous protection between two sites, ensuring zero data loss during failover. This is achieved by block-level replication that commits writes only after they are durably written at both sites, and it requires the appropriate MetroCluster licensing along with the necessary hardware and inter-site connectivity. It is not an asynchronous DR solution, it does not rely on NAS/file-level replication for protection, and it isn’t justified by software licensing alone—you need the full hardware and feature licensing to enable the synchronous, site-to-site HA setup. So the statement describing synchronous, site-to-site HA for zero data loss with two sites connected and required licensing best captures MetroCluster’s requirements.
