Explanation

Dell Unity XT offers both synchronous and asynchronous replication to protect data and ensure business continuity. Synchronous replication is used for zero RPO, ensuring no data loss, but it is typically limited to shorter distances due to latency concerns. Asynchronous replication is suitable for longer distances and provides near real-time data protection with a minimal RPO. Distance Considerations: The distance between Boston and Cambridge (8 km) is suitable for synchronous replication, providing zero RPO. The distance between Boston and New York (342 km) is better suited for asynchronous replication due to latency, ensuring data recovery with a minimal RPO, such as 15 minutes. Optimal Replication Strategy: Synchronous replication from Boston to Cambridge ensures zero RPO for critical data protection. Asynchronous replication from Boston to New York provides additional data protection with a 15- minute RPO, suitable for longer-distance disaster recovery.
