NS0-162 Exam - Question 58

Question

Which command parameter will result in a thin-provisioned LUN?

Examice · Accepted Answer

A thin-provisioned LUN can be achieved by disabling space reservations. When space reservations are disabled, space is allocated to the LUN only as data is written, which is the hallmark of thin provisioning.

Coreancowboy · Answer

Answer is D.  Space reserve is on a LUN level.  The Space guarantee is on a volume level.  Therefore Space reserve disable is the correct answer.
