Option B
Synchronous replication modes of replication requires a very low latency network connection and ensures data remains in synch with zero data loss in the event of a failure at the source site
<u>Explanation:</u>
Synchronous replication, information is replicated to a subsequent remote place at the identical period as fresh information is implying generated or renewed in the original datacenter. Actually, both master and target roots endure effectively synchronized, which is vital for triumphant crash restoration.
In the circumstances of synchronous replication, this indicates that the write is deemed ended barely when both local and isolated warehouses approve its fulfillment. Therefore, nullity data failure is assured, but the overall execution is regulated down.
