Which of the following is true regarding asynchronous replication?

answer

The local server sends an acknowledgement to the application writing the data, letting it know the write operation was successful.

When an application writes data to the disk on the local server, the local disk does not immediately acknowledge the I$/$O operation.

Storage Replica waits for the replication partner to acknowledge that the write operation was successful.

Acknowledgement of the write operation is sent to the application without waiting for an acknowledgement from the replication partner.
