Explanation

Synchronous Replication In synchronous remote replication, writes must be committed to the source and remote replica (or target), prior to acknowledging "write complete" to the host. Additional writes on the source cannot occur until each preceding write has been completed and acknowledged. This ensures that data is identical on the source and replica at all times. Further, writes are transmitted to the remote site exactly in the order in which they are received at the source. Therefore, write ordering is maintained. If a source-site failure occurs, synchronous remote replication provides zero or near-zero recovery-point objective (RPO).
