Huawei Certified ICT Professional – Storage (HCIP-Storage) — Question 4

In Huawei distributed storage systems, the asynchronous remote replication architecture of the block service establishes an asynchronous remote replication relationship based on a block service cluster. This architecture also synchronizes data between primary and secondary volumes based on differential data. All the data generated on the primary volume after the last synchronization will be written to the secondary volume in the next synchronization.

Answer options

Correct answer: B

Explanation

The correct answer is B because the statement incorrectly describes the behavior of the asynchronous replication, which does not guarantee that all data from the primary volume is immediately written to the secondary volume after each synchronization. Instead, only the differential data is replicated, which might not include every single change made since the last sync.
