With asynchronous technology, if any copy of a data item is updated anywhere on the network, the same update is immediately applied to all other copies or it is aborted.

Solution (By Examveda Team)

In asynchronous replication technology, updates to data items are not immediately applied to all other copies across the network. Instead, updates are propagated with a delay, and inconsistencies between copies may exist temporarily.

Option A: True
This option incorrectly describes the behavior of asynchronous replication. It suggests that updates are immediately applied to all copies of a data item across the network, which is characteristic of synchronous replication rather than asynchronous replication. In synchronous replication, updates are propagated synchronously, ensuring that all copies are kept consistent in real-time.

Option B: False
This option correctly describes the behavior of asynchronous replication. In asynchronous replication, updates to data items are not immediately applied to all copies across the network. Instead, updates are propagated asynchronously with a delay. As a result, temporary inconsistencies or lag may exist between copies until updates are fully propagated to all nodes.

Therefore, in the context of asynchronous replication technology in distributed database systems, the correct option is False (Option B).
