What are three benefits of using a few large-capacity LUNs instead of many small-capacity LUNs? (Choose
three.)
A.
Better performance because there is less contention for a single volume.
B.
More flexibility for resizing virtual disks.
C.
Less wasted storage space.
D.
More flexibility to create virtual machines without adding new LUNs.
E.
Fewer VMFS datastores to manage.

Agree to B,D,E
You might want fewer, larger LUNs for the following reasons:
■
More flexibility to create virtual machines without asking the storage administrator for more space.
■
More flexibility for resizing virtual disks, doing snapshots, and so on.
■
Fewer VMFS datastores to manage.
You might want more, smaller LUNs for the following reasons:
■
Less wasted storage space.
■
Different applications might need different RAID characteristics.
■
More flexibility, as the multipathing policy and disk shares are set per LUN.
■
Use of Microsoft Cluster Service requires that each cluster disk resource is in its own LUN.
■
Better performance because there is less contention for a single volume.
