A vSphere administrator enables Fault Tolerance on a powered off virtual machine that has the
following configuration:
• The virtual machine’s single thin provisioned virtual disk is sized at 100GB.
• The datastore that houses the virtual machine has 120GB of free space.
After Fault Tolerance has been configured, another administrator attempts to use Enhanced
vMotion to move a 30GB virtual machine file into the same datastore and receives an error.
What condition could cause this behavior?
A.
Fault Tolerance inflated the virtual machine’s virtual disk file.
B.
Fault Tolerance created a temporary logging file on the same datastore.
C.
Fault Tolerance created a secondary copy of the virtual machine’s virtual disk file.
D.
The Fault Tolerance logging file ran out of disk space.

Virtual machines must be stored in virtual RDM or virtual machine disk (VMDK) files that are thick provisioned. If a virtual machine is stored in a VMDK file that is thin provisioned and an attempt is made to enable Fault Tolerance, a message appears indicating that the VMDK file must be converted. To perform the conversion, you must power off the virtual machine.
