EMC Proven Professional – PowerMax Specialist — Question 48

When creating a new LUN on a Dell EMC Unity array using Unisphere, what is the default setting of the Data Reduction feature?

Answer options

• A. OFF for thick LUNs and ON for thin LUNs
• B. ON for thick LUNs and OFF for thin LUNs
• C. ON for thick LUNs in an All-Flash pool
• D. OFF for thin LUNs in an All-Flash pool

Correct answer: D

Explanation

The correct answer is D because, by default, Data Reduction is OFF for thin LUNs in an All-Flash pool. Options A and B incorrectly assign the default settings for thick and thin LUNs, while option C incorrectly states that Data Reduction is ON for thick LUNs in an All-Flash pool, which is not the default setting.
