An Administrator has determined that storage performance to a group of virtual machines
is reduced during peak activity. The virtual machines are all located in a VMFS datastore
called Production1.
Which of the following actions could be taken to improve the storage performance of
these virtual machines?

A.
Add additional physical storage, expand the underlying volume, then grow the VMFS
datastore into
The new space

B.
Change the storage multipathing policy to Most Recently Used (MRU)

C.
Add additional physical storage and add an extent to the VMFS datastore called
Production1

D.
Add additional physical storage, create a new VMFS datastore called Production2 on
the new storage, then migrate a portion of the virtual machines from Production1 to
Production2

Explanation:
Since the question does not refer to lack of storage, adding storage to the existing
datastore is unlikely to help, so neither A nor C are likely to improve performance.
Change the storage multipathing policy to Most Recently Used (MRU) will achieve little,
since the Most Recently Used path is likely to be the path used anyway.
Storage performance refers to how to how efficiently, (typically how quickly), storage
operates. By adding a new datastore, and migrate a portion of the virtual machines from
Production1 to Production2 is likely to reduce the load on the original datastore, and
hence improve responsiveness, and hence performance.
