A storage administrator must choose the best replication methodology for storage. The datacenters are on opposite sides of the country. The RPO is 24 hours. Replication and customer access use the…

Asynchronous replication sends data to the target after it has been committed locally, allowing the primary application to continue without waiting for remote acknowledgment. This significantly reduces performance impact over long distances and on shared connections, meeting the requirement to not impact customer access while achieving the 24-hour RPO.

"Regional" is a deployment model referring to location, not a specific replication methodology for data transfer.

"Multiregional" is a deployment model referring to multiple locations, not a specific replication methodology for data transfer.

Synchronous replication requires data to be written to both the primary and secondary sites before the write operation is acknowledged, which would introduce significant latency and directly impact customer access over long distances due to network round-trip times.
