A storage administrator performs a monthly performance analysis of a Dell EMC Unity XT storage array using CloudIQ insight reports. Three LUNs are set with a Host IO Limits policy. The administrator discovers that the throughput IOPS on one LUN (Test_LUN) has increased by 1000 IOPS compared to the two previous months.
What is a possible root cause of the spike in IOPS?

1. A. Test_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set for all three LUNs
2. B. Test_LUN was expanded by 100 GB and a Density-based Host IO limit policy was set only for Test_LUN
3. C. Host IO limit of Test_LUN was edited and the limit was increased by 1000 IOPS
4. D. Another Absolute Host IO limit policy with additional 1000 IOPS was set on Test_LUN

Correct Answer: C

When can a LUN be defined as thin or thick?

1. A. Any time after the LUN has been created
2. B. Only when creating the LUN
3. C. Only when enabling data reduction on the LUN
4. D. Only when adding host access to the LUN

Correct Answer: B

What is the total IOPS set by this policy?

1. A. 200
2. B. 500
3. C. 2000
4. D. 2500

Correct Answer: A
