Dell EMC D-MSS-DS-23 Exam - Topic 1 Question 27 Discussion

A customer has a data center with 30 different applications running on 30 volumes presented from PowerStore. They want to design a DR site within 300 km with 15 min RPO using storage-based asynchronous replication. Which protection policy design leads to most stable storage performance?
C) Create a single protection policy assigned to 30 volumes, each scheduled with a five minute shift from each other.
A) Create 15 protection policies that are assigned to a pair of volumes, each scheduled with a one minute shift from each other.
B) Create two protection policies that are assigned to 15 volumes, each scheduled with a five minute shift from each other.
D) Create 30 protection policies that are assigned to a single volume, each scheduled with a one minute shift from each other.

A customer has a data center with 30 different applications running on 30 volumes presented from PowerStore. They want to design a DR site within 300 km with 15 min RPO using storage-based asynchronous replication. Which protection policy design leads to most stable storage performance?

Show Suggested Answer Hide Answer
Suggested Answer: C

In a scenario where a customer needs to design a DR site with a 15-minute RPO using storage-based asynchronous replication, creating a single protection policy assigned to 30 volumes with a five-minute shift between each volume is the most stable design. This approach ensures that the replication load is evenly distributed over time, minimizing the impact on storage performance.

I’m a bit confused about the scheduling shifts. Would a one-minute shift really help with stability, or would it just complicate things?

This question feels similar to one we practiced where we had to balance RPO and performance. I think option B could be a good compromise.

I’m not entirely sure, but I think having a single protection policy might simplify management and improve stability.

I remember we discussed how too many protection policies could lead to performance issues, so I’m leaning towards fewer policies.
