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.
Correct Answer: A
Explanation/Reference:
Explanation:
A VDP appliance can be rolled back to a previous state by rolling back to a checkpoint.
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.
Incorrect Answers:
B: This answer says that the backup data will remain intact. The backup data will not remain intact. Therefore, this answer is incorrect.
C: It is not necessary to restore a backup. Furthermore, the latest backup may be a backup of the appliance taken whilst in its current unstable state. A rollback to the most recent validated checkpoint would ensure the appliance is rolled back to a stable state.
D: It is not necessary to restore a backup. Furthermore, the latest backup may be a backup of the appliance taken whilst in its current unstable state. A rollback to the most recent validated checkpoint would ensure the appliance is rolled back to a stable state.
