The current block size of a datastore in VMFS3 is 4MB. An administrator needs to upgrade
the datastore to VMFS5 and wants to change it to 1MB block size. Which action should the
administrator take?
A.
Upgrade the datastore to VMFS 5. Select the 1MB block size option during the upgrade.
B.
Create a new VMFS5 datastore with a 1MB block size. Migrate all virtual machines from
the existing datastore to the new datastore, then delete the VMFS3 datastore.
C.
Upgrade the datastore to VMFS5. Use vmkfstools to change the block size on the
upgraded datastore.
D.
Create a new VMFS5 datastore with a 1MB block size. Migrate all virtual machines from
the existing datastore to the new datastore. Upgrade the virtual machine hardware on the
migrated VMs, then delete the VMFS3 datastore.
