Your network contains an Active Directory domain named contoso.com. The domain
contains a server named Server1.Server1 runs Windows Server 2012 R2 and has the
Hyper-V server role installed.
On Server1, you create and start a virtual machine named VM1.VM1 is configured as shown
in the following table.
You need to recommend a solution to minimize the amount of disk space used for the
checkpoint of VM1.
What should you do before you create the checkpoint?
A.
Run the Resize-VHD cmdlet.
B.
Convert Disk1.vhd to a dynamically expanding disk.
C.
Shut down VM1.
D.
Run the Convert-VHD cmdlet.
Explanation:
A dynamically expanding disk is a VHD, which starts small — usually at only a few kilobytes –
– and expands as additional storage space is needed. It can only grow to the size limit you
designate in the setup wizard.
Answer is C – shut down the vm.

Agree that the answer should be C.
Just because the checkpoint will “save” the state of the virtual hard disks, does not mean that it is going to make a copy of the entire VHD, including empty, unused space. And MS advises shutting down the VM prior to creating a checkpoint. So that seems reason enough to go with answer C.

Agree with Klaus. The question is about the ‘disk space used for *checkpoints*’. A running VM checkpoint (snapshot) also includes the memory state for the VM oposite to the powered off VM checkpoint.
=> Answer is C !

I think a dynamically expanding disk will win more space in the checkpoint than shutdown will win in memory (2GB-4GB) or the disk should be almost full which is very unlikely with a just created and started VM.
=> answer was correct and should stay B

A dynamically expanded disk will not affect the size of the checkpoint. A checkpoint is by definition already a dynamically expanding disk that holds the differencing data between it and the original virtual hard disk. weather the virtual machine uses a fixed or dynamically expanding disk does not make a difference on the checkpoint size.

Why do you both think that a checkpoint saves the full capacity of the memory or hdd??
I’ve never seen that in ANY book and I’m on my third series of books.

omfg I am so wrong. Sorry.

For checkpoints created when the virtual machine is running
• The checkpoint contains the state of the hard disks and the data in memory.
• On the Checkpoints tab, the icon for the checkpoint has a small green triangle.
For checkpoints created when the virtual machine is stopped
• The checkpoint contains the state of the hard disks only.
• On the Checkpoints tab, the icon for the checkpoint has a small red square.

Stop/shutdown the VM looks to be right as the question stresses on “minimize the amount of disk space used for the checkpoint of VM1”. When a checkpoint/snapshot of a VM is created then a new file is created and the original vhd/x is not touched.
So to minimize the size taken up by the checkpoint file the VM needs to be stopped. Converting the vhd to dynamic can help to decrease the space being occupied on the storage media by the vhd file and not help in reducing the size of checkpoint file.

the right answer is C.
Shut down the vm before creating the checkpoint.

Absolutely C. It is not B due to the way snapshots work. The way a snapshot/checkpoint works is that the VHDX file is frozen and all subsequent writes are written to the snapshot file (.AVHDX) instead. Whether or not you change the source VHDX file from fixed to dynamically expanding has nothing to do with the snap. Take the following example for consideration…
1. You take a snapshot.
2. you write 512KB of new data on the VM
The 512KB of data will be written to the snapshot (AVHDX). 512KB is 512KB – it has to be written to the snapshot. The size of the original VHD is inconsequential and will do nothing to change the fact that you are writing 512KB of new data.
Evidence:
See https://technet.microsoft.com/en-us/library/dn818483.aspx. The first big image on the page is https://i-technet.sec.s-msft.com/dynimg/IC756842.png which states “All updates to VHDX now made to AVHDX”.

I tend to agree with answer C but I’d like to put submit to all the following: When a checkpoint is created, all changes are written to a .AVHDX file. That’s absolutely correct. Consequently, once the checkpoint has been created, the current/live VM is the sum of a VHD and a AVHDX file; this would suggest that the snapshot is in fact the frozen VHD, not the newly created AVHDX. From this perspective converting the VHD to dynamic would actually reduce the size of the checkpoint (the VHD file) as it would shrink the VHD file from 100GB to the space what is actually been used by the files on the VM. Food for thought…

I think first time take snapshot action. the frozen VHD is snapshot file ,AVHDX file just saved the changed file storage. If you would convert a VHD file,the vm must turnoff before. So B is correct.

C is correct answer! Some people make confusion with questioning which file is checkpoint. VHD(X) cannot be checkpoint (AVHDX is checkpoint) because if you didn’t create any checkpoint you have VHD(X) (but not checkpoint). When you create new checkpoint, AVHDX is created, not VHD(X) and if you have 5 checkpoints, there is one VHD(X) and 5 AVHDX files. Similar is going on when you delete checkpoint, AVHDX is deleted. So, question is how to reduce storage space required for checkpoint, not for original VHD(X) file.

According to my instructor, the VM must be shutdown before creating the checkpoint. Answer is C

I dont see how people are arguing about this question…
The answer is clearly C. Shut Down VM1
Just a heads up to everyone else that thinks otherwise…
What does converting to a dynamically expanding disk have to do with the checkpoints???
clearly nothing…. even if you did change it to dynamically expanding disk the checkpoints will still be saved the same way…
Read the question carefully and make sure you know what it is asking for.
These questions are meant to through you off, Microsoft wants to make sure you understand everything and throw a curve ball at you at the same time.
Hope this helps second guessers
Cheers! 😀

Correct answer is: C
Explanation:
Use the following procedure to create a checkpoint for a selected virtual machine. Checkpoints enable you to recover a virtual machine to a previous state. You can create as many as 64 checkpoints per virtual machine. You can create checkpoints only when a virtual machine is deployed on a host. For more information, see About Virtual Machine Checkpoints.
It is advisable to shut down the virtual machine before creating a checkpoint. However, you can create a checkpoint while a virtual machine is in a Stopped or Turned Off state. Doing so stops the virtual machine momentarily while the checkpoint is created. If Virtual Machine Additions is not installed on the virtual machine, the virtual machine is not shut down. Instead, it is simply stopped; this is similar to switching off the power on a physical machine while it is still running. To avoid losing any data, ensure that the virtual machine is not in use and that no processes are running on the virtual machine.

Answer is C. Microsoft says so.
Reference:
https://technet.microsoft.com/en-us/library/bb740891.aspx
What Is a Checkpoint?
Each checkpoint saves the state of each virtual hard disk that is attached to a virtual machine and all of the hard disk’s contents, including application data files.
Use the Recover action to restore a virtual machine to its state when a checkpoint was created. For more information, see How to Restore a Virtual Machine to a Checkpoint. When you no longer need to recover a virtual machine to a checkpoint, you should merge the checkpoint to delete the associated files and recover disk space. For more information, see How to Merge a Checkpoint.
You can create as many as 64 checkpoints for any one virtual machine. However, checkpoints use disk space and, when allowed to proliferate over long periods, can affect performance during operations such as migrating a virtual machine. For this reason, it is a good practice to routinely merge unneeded checkpoints.
Checkpoints are portable. When you migrate, store, or deploy a virtual machine, any existing checkpoints move with the virtual machine.
Creating Checkpoints
You can create checkpoints only when a virtual machine is deployed on a host. You cannot create checkpoints when a virtual machine is stored in the library.
It is advisable to shut down the virtual machine before creating a checkpoint. However, you can create a checkpoint while a virtual machine is in a Stopped or Turned Off state. Doing so stops the virtual machine momentarily while the checkpoint is created. If Virtual Machine Additions is not installed on the virtual machine, the virtual machine is not shut down. Instead, it is simply stopped; this is similar to switching off the power on a physical machine while it is still running. To avoid losing any data, ensure that the virtual machine is not in use and that no processes are running on the virtual machine.

Answer C:
For checkpoints created when the virtual machine is stopped
The checkpoint contains the state of the hard disks only.
For checkpoints created when the virtual machine is running
The checkpoint contains the state of the hard disks and the data in memory.
Note: A checkpoint saves the state of each virtual hard disk that is attached to a virtual machine and all of
the hard disk’s contents, including application data files. For virtual machines on Hyper-V and VMware
ESX Server hosts, a checkpoint also saves the hardware configuration information. By creating
checkpoints for a virtual machine, you can restore the virtual machine to a previous state.

Answer is B. The first checkpoint created IS the original vhd at that point in time, not the differencing disk(avhdx). The differencing disk (avhdx) stores the changes since the last checkpoint, it is not the checkpoint in itself. When you apply the first checkpoint, it ignores the avhdx file. So creating a dynamic vhd will minimize the amount of disk space used for the checkpoint
0

C is likely to be correct.
Reason:
**Practically, when you create a checkpoint while the VM is running, the size of the .avhdx file is many times bigger than when you create a checkpoint while VM is not running.
**Also, when the VM is running, the size of the created .avhdx file keeps expanding almost every two minutes (I observed this). This makes the .avhdx to grow big and consume more space.The size of the .avhdx has less to do with the type of the VHD (Fixed or dynamically expanding).
See picture of the observation https://itconsults1.wordpress.com/2016/11/16/hyper-v-vm-checkpoints/

Answer “C” makes the most sense because when shutting down the VM will clear the memory and every process. and the size of the checkpoint will be smaller than when creating it when the VM is running, but lets pay attention a the image. It clearly states “Disk Type: Fixed Size / Disk Size:100Gb” so if the disk size is 100Gb the checkpoint will always be big because the VHD is FIXED.
the steps to optimize the size of the checkpoints in this case should be:
1 – convert it to dynamic expanding disk
2 – Shutdown the VM
3 – Create a checkpoint
so the answer is “B”
I seen this answer from premium dumps with the answer been B or C. just pay attention to the questions and the images in the questions.

Correct Answer: B
You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the
Hyper-V server role installed. On Server1, you create a virtual machine named VM1. VM1 has a legacy network adapter.
You need to assign a specific amount of available network bandwidth to VM1.
What should you do first?
Options
A. Remove the legacy network adapter, and then run the Set-VMNetworkAdapter cmdlet.
B. Add a second legacy network adapter, and then run the Set-VMNetworkAdopter cmdlet.
C. Add a second legacy network adapter, and then configure network adapter teaming.
D. Remove the legacy network adapter, and then add a network adapter.
Correct Answer: D
