Which of the following replication types depends on receiving an ACK from the remote system and guarantees a zero data loss solution?

Synchronous replication ensures data integrity by writing data to both primary and secondary storage simultaneously and waiting for an acknowledgment from the secondary site before confirming the write operation to the application, thus guaranteeing zero data loss.

Asynchronous replication commits data locally and then sends it to the remote site without waiting for an immediate acknowledgment, which means there could be some data loss in a disaster scenario.

Point-in-time replication refers to snapshots or backups taken at specific moments, not a continuous replication method that guarantees zero data loss.

Differential replication is a backup method that saves only data changed since the last full backup, not a real-time data replication solution guaranteeing zero data loss.
