    • Synchronous

    Correct Answer
    A. Synchronous
    Explanation
    Synchronous replication requires a continuous and consistent connection between the two sites in order to replicate data in real-time. However, since site A and site B are 1000 miles (1600 km) away, it is not feasible to maintain a stable and low-latency connection over such a long distance. Therefore, synchronous replication is not suitable for remotely replicating data from site A to site B in this scenario.
