Replication may use either synchronous or asynchronous distributed database technologies, although asynchronous technologies are more typical in a replicated environment.

Solution (By Examveda Team)

Replication in distributed database systems can utilize either synchronous or asynchronous technologies for data propagation and synchronization. However, asynchronous technologies are more commonly employed in a replicated environment due to their advantages in terms of performance and scalability.

Option A: True
This option correctly states that replication may utilize both synchronous and asynchronous distributed database technologies. Synchronous replication involves immediate data propagation and acknowledgment of updates across all replicas before committing a transaction, ensuring data consistency but potentially introducing latency and performance overhead. Asynchronous replication, on the other hand, allows updates to be propagated to replicas with a delay, enabling faster transaction processing but potentially leading to data inconsistencies or discrepancies between replicas. While both approaches have their benefits and trade-offs, asynchronous technologies are more prevalent in replicated environments due to their ability to provide higher performance and scalability.

Option B: False
This option contradicts the statement provided in the question. It suggests that only synchronous technologies are typical in a replicated environment, which is not accurate. While synchronous replication is suitable for scenarios requiring strict data consistency and integrity, asynchronous replication is more commonly used in replicated environments due to its advantages in terms of performance, scalability, and fault tolerance.

Therefore, in the context of replication technologies in distributed database systems, the correct option is True (Option A).
