An error occurs while building a new virtual machine with a thin provisioned virtual disk size of 20GB. The datastore has 35GB of free space. The datastore is overcommitted by 95GB.
What is preventing the virtual machine from being built?
A. The datastore is built on a thin provisioned LUN that has run out of storage array free space.
B. The datastore has reached the maximum overcommitment threshold.
C. The virtual disk used by the virtual machine cannot be thin provisioned on this datastore.
D. The virtual disk used by the virtual machine requires more free space than is available in the datastore.
Correct Answer: A
Explanation/Reference:
Explanation:
A: With Thin provision as the disk format, the virtual disk will only make use of the space required in the datastore. And in this case it has run out of storage array free space thus preventing the virtual machine from being built.
Incorrect Answers:
B: It is mentioned in the question that the virtual machine is to be built with thin provisioning disk format and the data store that is being used cannot exceed the required space. Thus it is not a matter of the maximum overcommitment threshold being reached when being built on thin provisioning.
C: The disk format being used, i.e. thin provision in this case is not the problem, but rather the lack of free space of the storage array.
D: Overcommitment is not the reason why the virtual machine cannot be built since it is a matter of the datastore that is problematic.
