An administrator has deployed a vSphere 5 implementation. Due to security reasons the system state of a virtual machine must be reverted on a regular basis what feature will meet this requirement?
Create the virtual machine using Independent-Persistent disks
Create a Scheduled Task using the Delete All Snapshots option according to security requirements
Create the virtual machine using Independent-Nonpersistent disks
Create a Scheduled Task using the Delete Snapshot option to delete the most recent snapshot according to security requirements.
If you delete snapshot then you cannot revert VM deleting will merge snapshot to VM so it will be permanent. So B and D are wrong.
C is OK, but it will not revert VM on a regular basis just when VM is restarted.
