Question 31

An administrator is performing maintenance activities and discovers that a Virtual Machine File System (VMFS) datastore has a lot more used capacity than expected. The datastore contains 10 virtual machines (VMs) and, when the administrator reviews the contents of the associated datastore, discovers that five virtual machines have a snapshot file (-delta.vmdk files) that has not been modified in over 12 months. The administrator checks the Snapshot Manager within the vSphere Client and confirms that there are no snapshots visible.

Which task should the administrator complete on the virtual machines to free up datastore space?

    Correct Answer: A

    When a VMFS datastore has unmodified snapshot files that are not visible in the Snapshot Manager, it indicates that these snapshot files are left over or orphaned and need to be consolidated. The correct task is to consolidate the snapshots for each VM, which will merge the data from the delta files back into the base disk and free up the used space. This process ensures that the snapshot data is correctly integrated and unnecessary files are removed, optimizing the datastore capacity usage.

Discussion
mkhlszfOption: A

Should be option A: "For virtual machines that are not reported to have snapshots in the VMware vSphere or Infrastructure Client, commit or remove the snapshot delta disks." https://kb.vmware.com/s/article/1005049

ABCACBOption: A

The presence of redundant delta disks can adversely affect the virtual machine performance. You can combine such disks without violating a data dependency. After consolidation, redundant disks are removed, which improves the virtual machine performance and saves storage space.

English version, "Consolidate Snapshots" is near the end of the page. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-vm-administration/GUID-50BD0E64-75A6-4164-B0E3-A2FBCCE15F1A.html

Juan_Ochoa_TI724Option: A

In this case option A is correct, since the snapshots are not visible in the vSphere.

[Removed]Option: C

No such action called "Consolidate". The action is Delete All. It is consolidating the snapshots. https://kb.vmware.com/s/article/1023657#:~:text=Deleting%20Snapshots&text=Deleting%20a%20snapshot%20does%20not,snapshot%20to%20the%20parent%20disk.

From ICMv.8, 8-70: "Snapshot consolidation is a method for committing a chain of delta disks to the base disks when the Snapshot Manager shows that no snapshots exist, but the delta disk files remain on the datastore." and "Snapshot consolidation is a way to clean unneeded delta disk files from a datastore. If no snapshots are registered for a VM, but delta disk files exist, snapshot consolidation commits the chain of the delta disk files and removes them."

gtapiaOption: C

C. Delete all snapshots for each VM.

StingVNOption: C

To free up datastore space in this scenario where there are lingering snapshots (-delta.vmdk files) that are not visible in the Snapshot Manager, you should: C. Delete all snapshots for each VM. These snapshots that are not visible in the Snapshot Manager are often referred to as "orphaned snapshots." Deleting these snapshots will merge the changes from the snapshot delta files back into the original virtual disks and free up space on the datastore. Make sure to perform this action carefully to avoid any data loss.
