What is a characteristic of asynchronous remote replication?
The correct answer is A. Replica will be behind the source by at least the size of the buffer. Asynchronous remote replication In asynchronous remote replication, a write is committed to the source and immediately acknowledged to the host. In this mode, data is buffered at the source and transmitted to the remote site later. Data at the remote site will be behind the…

Explanation
Asynchronous remote replication In asynchronous remote replication, a write is committed to the source and immediately acknowledged to the host. In this mode, data is buffered at the source and transmitted to the remote site later. Data at the remote site will be behind the source by at least the size of the buffer. Hence, asynchronous remote replication provides a finite (nonzero) RPO disaster recovery
