You administer a Windows Server 2012 R2 server thathas the Hyper-V role installed. You plan to test an
update to a virtual machine (VM) in a production environment. You must meet the following requirements:
migrate the VM to another Hyper-V host as quickly as possible ensure that the VM configuration is preserved
after the migration is complete
You need to migrate the virtual machine. What should you do first?
A.
Create a checkpoint of the VM.
B.
Run the Windows PowerShell cmdlet Export-VMSnapshot.
C.
Run the Windows PowerShell cmdlet New-VirtualDiskClone.
D.
Export the VM.
D is correct, I personally use this option.
Why A: “Create a checkpoint of the VM.” is not correct?
Creating a checkpoint does not help to migrate the VM to another host, which is one of the requirements. While in the real world, a checkpoint may be a good method to test an update and have the ability to roll back, in this case it doesn’t help you.
Should be D. This is the way to preserve the configuration after the migration on both of the hosts – the “source” host will keep the powered off state of the VM and on the “destination” host will run the “migrated” VM.
Answer is “D” because:
Exporting Hyper-V Virtual Machines in Windows Server 2012 R2
Exporting is a great way to archive a VM which is no longer needed, or as an ad-hoc backup. In Windows 2012 and previous versions, VMs could only be exported while they were powered off.
With Windows Server 2012 R2, the export feature becomes even more useful. VMs can now be exported while they are running. This means you can create a backup of a VM without ever taking it down.
Before Windows Server 2012 we also did not have the ability to export a VM directly to a network share. Instead, the VM would be exported to local storage and then copied across the network to an archive location. Now we can export directly to a desired network share.
Have you ever thought about adding a little bit more than just your articles? I mean, what you say is valuable and all. Nevertheless think of if you added some great images or video clips to give your posts more, “pop”! Your content is excellent but with images and videos, this site could certainly be one of the very best in its niche. Fantastic blog!|
