A VMFS3 datastore has just been upgraded to VMFS5. In what two ways does this affect the partition format? (Choose two)

A.
The partition format is retained, which is the MBR (Master Boot Record) format.

B.
The partition format is retained, which is the MBR (Master Boot Record) format. To change the GPT (Guide Partition table) format, the datastore must be re-formatted.

C.
The partition format is retained, but will be upgraded to GPT (GUID Partition Table) format once the datastore exceeds 2TB.

D.
The partition format is upgraded to the GPT (GUID Partition table) format

VMFS Datastores and Storage Disk Formats
Storage devices that your host supports can use either the master boot record (MBR) format or the GUID partition table (GPT) format.
With ESXi 5.0, if you create a new VMFS5 datastore, the device is formatted with GPT. The GPT format enables you to create datastores larger than 2TB and up to 64TB.
VMFS3 datastores continue to use the MBR format for their storage devices. Consider the following items when you work with VMFS3 datastores:
* For VMFS3 datastores, the 2TB limit still applies, even when the storage device has a capacity of more than 2TB. To be able to use the entire storage space, upgrade a VMFS3 datastore to VMFS5. Conversion of the MBR format to GPT happens only after you expand the datastore.
* When you upgrade a VMFS3 datastore to VMFS5, any spanned extents have the GPT format.
* When you upgrade a VMFS3 datastore, remove from the storage device any partitions that ESXi does not recognize, for example, partitions that use the EXT2 or EXT3 formats. Otherwise, the host cannot format the device with GPT and the upgrade fails.
* You cannot expand a VMFS3 datastore on devices that have the GPT partition format.
