A vSphere administrator needs to temporarily disable DRS on a cluster containing a resource pool hierarchy.
Which procedure should the administrator follow to preserve the resource pool hierarchy while DRS is disabled?
A. Move the resource pool hierarchy out of the cluster prior to disabling DRS.
B. Save the resource pool hierarchy to the administrator’s local machine prior to disabling DRS.
C. Backup the vCenter Server database and restore the database after re-enabling DRS.
D. Create a new cluster and move the resource pool hierarchy to the new cluster prior to disabling DRS.
Correct Answer: B
Explanation/Reference:
Explanation:
After disabling DRS, the cluster’s resource pool hierarchy and affinity rules are not retained when DRS is turned back on. If you disable DRS, the resource pools are removed from the cluster.
To preserve the resource pool hierarchy while DRS is disabled, you should save the resource pool hierarchy to a local machine prior to disabling DRS.
To disable DRS in the vSphere Web Client:
Browse to the cluster in the vSphere Web Client navigator.
Click the Manage tab and click Settings.
Note: Alternatively, in the vSphere 5.5 Web Client, you can right-click the cluster and click Settings.
Under vSphere DRS, click Edit.
Deselect the Turn On vSphere DRS option.
Click OK to turn off DRS.
Select an option to save the resource pool.
Click Yes to save a resource pool tree snapshot on a local machine.
Click No to turn off DRS without saving a resource pool tree snapshot.
Incorrect Answers:
A: It is not possible to move the resource pool hierarchy out of the cluster prior to disabling DRS. Resource pools and the child resource pools can only be moved within a resource pool hierarchy. Therefore, this answer is incorrect.
C: Backing up the vCenter database will not backup the resource pools. Therefore, this answer is incorrect.
D: It is not possible to move the resource pool hierarchy to a new cluster prior to disabling DRS. Resource pools and the child resource pools can only be moved within a resource pool hierarchy. Therefore, this answer is incorrect.
