A VMware Administrator needs to restore a VM after a recent server patch update has corrupted the VM operating system. What is the quickest way to…

The quickest and most efficient method for a VMware Administrator to restore a single virtual machine is by using the SnapCenter Plug-in for VMware vSphere directly from the vCenter client. This integrated approach provides a streamlined, wizard-driven workflow that automates the entire restore process. The administrator can select the corrupted VM, choose a valid backup, and initiate the restore with a few clicks without leaving their primary management interface (vSphere client). This method is purpose-built for this scenario, minimizing administrative overhead and time-to-recovery compared to manual, multi-step alternatives.

B. While restoring from the SnapCenter Server is a valid method, it requires the administrator to switch from the vSphere client to a separate management interface, making it a less direct and slightly slower workflow.

C. Creating a FlexClone from ONTAP System Manager is a manual, multi-step process. It requires creating the clone, mounting it as a new datastore in vSphere, and manually registering the VM, which is significantly slower than the automated SnapCenter restore.

D. Rolling back the entire datastore volume is a highly disruptive action. It would revert all VMs on that datastore to a previous point in time, causing data loss for any other healthy VMs on the same datastore.

1. NetApp SnapCenter Data Protection Guide for VMware vSphere, Version 4.8, Page 101, "Restore a virtual machine": The documentation outlines the procedure for restoring a VM, which is initiated from the vSphere client. It states, "You can restore a virtual machine (VM) from a Snapshot copy of a datastore or a VM. The restore operation overwrites the target VM with the data from the selected Snapshot copy." The process described is a simple, integrated workflow within vCenter.

2. NetApp Technical Report TR-4597: SnapCenter Best Practices, Page 20, Section 3.4 "Restore": This report emphasizes the simplicity of the integrated tool. It states, "The SnapCenter Plug-in for VMware vSphere provides several options for restoring VMs and VMDKs... The restore workflow is wizard driven and easy to use." This highlights that the intended, and therefore quickest, method is the automated wizard within the vSphere plugin.

3. NetApp Product Documentation, "How SnapCenter Plug-in for VMware vSphere restores a VM": This documentation details the automated steps SnapCenter performs behind the scenes, such as unregistering the VM, performing a SnapRestore on the underlying storage, and re-registering the VM. This automation is inherently faster and less error-prone than performing these steps manually as described in option C.
