Question

An administrator is attempting to remove a remote replication session for a test volume. The administrator selects the test volume from the Storage tab. From the More Actions dropdown list the Unassign Protection Policy is selected. In the Unassign Protection Policy confirmation window the administrator clicks the Unassign button and receives a Modify Volume error. What is the cause of the error?

Options

  • AProtection policy replication rule RPO value was not set to zero
  • BOperation was performed from the replication destination
  • CReplication session was not paused before the protection policy was unassigned
  • DReplication rule was not deleted from the protection policy

Explanation

Option B is correct because in a replication setup, the destination volume is read-only and managed by the replication system - administrative changes like unassigning a protection policy can only be performed from the source side. Attempting to modify volume settings on the destination triggers a "Modify Volume" error because the system protects destination volumes from direct changes.

Why the distractors are wrong:

  • A is incorrect - the RPO value has no bearing on whether you can unassign a protection policy; it controls recovery point frequency, not administrative permissions.
  • C is incorrect - pausing the replication session is not a prerequisite for unassigning a protection policy; you can unassign without pausing.
  • D is incorrect - you don't need to delete the replication rule from the protection policy before unassigning; the unassign operation handles the policy relationship directly.

Memory tip: Think "Source = Control" - in any replication relationship, the source side holds administrative authority. If you get a modify error, your first instinct should be to verify you're working from the source, not the destination.
