A customer recently upgraded from vSphere v4.x to vSphere v5.0 to benefit from new VMFS-5
features for their existing ‘DataStore1’ and ‘DataStore2’ datastores on an EMC VNX. A second
identically configured VNX was implemented and the customer created two additional datastores
on the new VNX.
After monitoring the environment, the customer notices the VMs on ‘DataStore1’ and ‘DataStore2’
are not using the same sub-block structure as the two new datastores.
What is the reason for this behavior?

A.
The old VMs are on an upgraded VMFS-5 datastore.

B.
The old VMs are still running old VMware tools.

C.
The new VMFS-5 features need to be licensed and activated.

D.
The new VMFS-5 cannot support two VNX storage systems.
