Asynchronous replication is defined as which of the following?

This scenario describes an unusual or inverse replication model, not standard asynchronous replication where the primary site is the source.

In asynchronous replication, the primary storage system acknowledges the data write to the application host immediately after writing the data locally. The data is then replicated to the secondary site in the background, without the primary site waiting for confirmation from the secondary, thus minimizing latency impacts on the primary application.

This describes synchronous replication, where the primary site waits for the secondary site to confirm receipt and write of data before acknowledging the write to the host.

This is inaccurate; acknowledgment happens from the primary, and in synchronous replication, it waits for secondary confirmation. Simultaneous acknowledgment from both to the host is not how replication typically functions.
