A system administrator detects that a VDP Appliance that has been operational for 6 months has
become inconsistent or unstable.
Which action should the administrator take to recover the VDP appliance and what will be the
impact on the vSphere environment?
A.
Perform a VDP rollback to the most recent validated checkpoint. All backup and configuration
changes made after the checkpoint will be lost.
B.
Perform a VDP rollback to the most recent validated checkpoint. Configuration changes after
the checkpoint will be lost, but backup data will remain intact.
C.
Restore a copy of the latest backup of the VDP appliance. All backup data and configuration
changes after the backup was made will be lost.
D.
Restore a copy of the latest backup of the VDP appliance. All configuration changes after the
backup was made will be lost, but backup data will remain intact.
Explanation:
A is correct
It is strongly recommended that you only roll back to the most recent validated checkpoint.
check the rollback section in this article

The vSphere Data Protection (VDP) Appliance could become inconsistent or unstable. In some cases, the VDP configuration utility can detect an inconsistent or unstable state and will provide a message similar to this immediately after you log in:
It appears that your VDP Appliance has suffered an unclean shutdown and will likely require a checkpoint rollback to restore data protection functionality. This process may be initiated from the ’Rollback’ tab.
CAUTION By default, VDP keeps two system checkpoints. If you rollback to a checkpoint, then any backups or configuration changes to the VDP Appliance between the checkpoint and the rollback are lost.
The first checkpoint is created when VDP is installed. Subsequent checkpoints are created by the Maintenance service. This service is disable the first 24-48 hours of VDP operation. In the event that you rollback during this time frame, then the VDP Appliance is set to default configuration and any backup configurations or backups are lost.
I disagree with “A” because the information from the guide is confusing. It states: “in the event that you rollback during this time frame (the first 24-48 hours of VDP operation), then the VDP Appliance is set to default configuration and any backup configurations or backups are lost” The question states that the appliance has been running for six months therefore a rollback will not “default” the appliance, and backups should not be lost.
Karl, A doesn’t say it will “default” the installation just that it will lose ” all backup and configuration changes since the last checkpoint”
