A VMFS3 datastore has just been upgraded to VMFS5.
In what two ways does this affect the datastore? (Choose two.)
A. The existing VMFS3 block size is retained.
B. The block size will be changed to 8MB.
C. Any existing VMDK can be expanded up to 2TB.
D. VMDKs retain their size limit from the VMFS3 block size.
Correct Answer: AC
Explanation/Reference:
If you upgrade to VMFS-5 from VMFS-3 then regardless of the block size, VMFS-5 uses double-indirect addressing to cater for large files (up to a size of 2 TB – 512 B) on upgraded VMFS-3 volumes. For example, if the VMDK goes beyond 512 GB it will switch to using double-indirect addressing, which will allow for VMDKs up to 2 TB – 512 B.
