Dell EMC Specialist – Systems Administrator, PowerEdge Server — Question 41

A production PowerMax array has been configured to replicate to a disaster recovery (DR) array using SRDF Adaptive Copy mode. There are occasional bandwidth constraints on the network connecting the two arrays. These bandwidth constraints prevent the immediate replication of production data.

Where does the new production data accumulate until it can be replicated to the array at the DR site?

Answer options

• A. Local journal volumes
• B. Local array cache
• C. R1 device
• D. R2 device

Correct answer: A

Explanation

The correct answer is A, as new production data is stored in local journal volumes until it can be replicated to the DR site. Options B, C, and D are incorrect because the local array cache is used for temporary storage during I/O operations, while R1 and R2 devices refer to the primary and secondary copies of data in SRDF, which do not hold unreplicated data.
