Dell EMC Specialist – Systems Administrator, Unity — Question 1

A Dell EMC SC Series customer has purchased the Storage Optimization bundle and wants to ensure that Data Progression works efficiently. Which snapshot schedule conforms to best practice when using Data Progression?

Answer options

• A. Daily snapshot with an expiration of no more than 23 hours
• B. Daily snapshot with an expiration of exactly 24 hours
• C. Daily snapshot with an expiration of at least 25 hours
• D. Daily snapshot configured with no expiration time

Correct answer: B

Explanation

The correct answer is B because a daily snapshot with an expiration of exactly 24 hours aligns with best practices for Data Progression, allowing the system to efficiently manage data movement. Options A and C do not meet the 24-hour requirement, while option D leaves snapshots indefinitely, which can hinder performance and storage efficiency.
