Dell Technologies Proven Professional – Midrange Storage Solutions — Question 64
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?
Answer options
- A. Create 30 protection policies that are assigned to a single volume, 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.
- C. Create a single protection policy assigned to 30 volumes, each scheduled with a five-minute shift from each other.
- D. Create 15 protection policies that are assigned to a pair of volumes, each scheduled with a one-minute shift from each other.
Correct answer: B
Explanation
Option B is correct because it reduces the number of protection policies and balances the load across 15 volumes, leading to more stable performance. The other options either overload a single volume with too many policies (A and C) or create excessive granularity that complicates management without improving performance (D).
