Dell Technologies Proven Professional – Unity XT — Question 4

What is the result of enabling Data Reduction on a LUN in a consistency group containing three LUNs?

Answer options

• A. Any writes to the LUN will go through the Data Reduction logic.
• B. Data Reduction and Advanced Deduplication will be enabled on all LUNs.
• C. Data Reduction will be enabled on all LUNs is the consistency group.
• D. All writes to all consistency group LUNs will go through the Data Reduction logic.

Correct answer: C

Explanation

The correct answer is C because enabling Data Reduction on one LUN in a consistency group automatically applies it to all LUNs within that group to maintain data integrity and consistency. Answers A and D are incorrect because they imply data reduction applies only to individual LUNs or selectively, rather than to all LUNs in the group. Answer B is also incorrect as it mentions Advanced Deduplication, which is not necessarily enabled just by activating Data Reduction.
