Dell Technologies Proven Professional – Midrange Storage Solutions — Question 59

A customer has a data center with applications running on 16 volumes that are presented from a Dell Unity XT system. They want to design a DR site within metro distance with zero RPO using storage-based replication.

According to Dell best practices, which design approach minimizes the impact on storage performance?

Answer options

• A. Use multiple ports per controller for replication.
• B. Create the synchronous replication session before filling the source storage object with data.
• C. Include a Flash tier in a hybrid pool where synchronous replication is active.
• D. Use Thick volumes within the replication group.

Correct answer: B

Explanation

Establishing the synchronous replication session before any data is written to the source storage object ensures that the replication process is optimized from the start, minimizing performance impacts. The other options, while they may have their own benefits, do not directly address the timing of session creation in relation to data population, which is critical for maintaining performance.
