Asynchronous technology can result in unsatisfactorily slow response time because the distributed DBMS is spending considerable time checking that an update is accurately and completely propagated across the network.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
The statement is true. Asynchronous replication technology can lead to unsatisfactorily slow response times because the distributed DBMS spends considerable time ensuring that updates are accurately and completely propagated across the network.Option A: True
This option correctly affirms the statement provided in the question. In asynchronous replication, updates are propagated across the network with a delay, and the distributed DBMS must verify that updates are accurately and completely propagated to all replicas before committing the transaction. This verification process can introduce latency and overhead, resulting in slower response times, especially for transactions that require immediate confirmation or synchronization across distributed nodes.
Option B: False
This option contradicts the statement provided in the question. Asynchronous replication technology, by its nature, introduces delays in propagating updates across the network to achieve eventual consistency. These delays can indeed lead to slower response times, particularly in scenarios where immediate data consistency or synchronization is required.
Therefore, in response to the question, the correct option is True (Option A).
