A. The cost of the replica matches the cost of the source volume; for example, the replica of a high-performance volume will be billed at the high-performance rate.

B. The replica cannot be directly mounted on a compute instance. Instead, it must be activated, creating a clone that will be available for mounting.

C. Replication replaces the need for block volume backups.

D. Replication is synchronous, so it may slightly degrade block volume performance.
