AZ-104 Exam - Question 494

Question

You have an Azure virtual machine named VM1.

You use Azure Backup to create a backup of VM1 named Backup1.

After creating Backup1, you perform the following changes to VM1:

✑ Modify the size of VM1.

✑ Copy a file named Budget.xls to a folder named Data.

✑ Reset the password for the built-in administrator account.

✑ Add a data disk to VM1.

An administrator uses the Replace existing option to restore VM1 from Backup1.

You need to ensure that all the changes to VM1 are restored.

Which change should you perform again?

Examice · Accepted Answer

Restoring a virtual machine from a backup using the 'Replace existing' option will revert the VM to its state at the time the backup was created. This means any changes made after the backup will be lost. Modifying the size of the VM, resetting the password, and adding a data disk do not need to be redone because the restore process either retains these changes or requires simple configuration tweaks. The file 'Budget.xls' copied to a folder named 'Data' after the backup will be lost and must be copied again to ensure it is available.

If it's a single selection, I would select D. However, the test result reveals it should be two (C and D).

I have tested this in Azure. 
Prepare
1.	Create a Windows VM with size D2S_v3.
2.	Backup the VM. 
Made changes after the backup.
1.	Modify the VM size to DS1_v2.
2.	RDP to the VM and create a new file.
3.	Reset the password for the built-in administrator.
4.	Add a data disk to the VM.

Restore the VM from the backup. Here are the results:
1.	VM size remains as DS1_v2.
2.	RDP to VM with the changed password. 
3.	Data disk is gone.
4.	A new file is gone.

Conclusion, VM size and password will not be overridden by the restore process. 
You will need to perform the changes again:
1.	Add a data disk
2.	Copy the file.

The correct answer is D, i.e., copy the file again. 
a. You don't need to resize the VM after backup. The latest size will be applicable. 
b. The latest credentials will work.
c. This one is a bit ambiguous. The additional data disk will not be deleted after the restoration. However, you will have to attach it again to the VM.
D. The file will be lost and needs to be created again.

Phlogiston · Answer

Stupid, ambiguous question that should not have made it past QA. Assuming that events are described in order, the file is copied to a folder named Data, which must exist on C:. That said, we do not know with any certainty where this folder resides because there is no explicit indication. It could reside on the C: drive but this is based on an inference that the question posits the activities in the order they were performed. However, the similarity between the folder name (Data) and the "data" disk in the question also causes the reader to make an inference about the location of the folder. The best answer is, therefore, C because you will always have to attach the additional drives after a restoration. D: is also valid if the Data folder is on the data drive, but we have no way of knowing this with any certainty. /rant off

B. Reset the password for the built-in administrator account.

This change should be performed again because restoring a virtual machine from a backup using the "Replace existing" option will restore the virtual machine to its state at the time the backup was created. Any changes made after the backup was created will be lost and will need to be performed again. In this case, resetting the password for the built-in administrator account is a change that was made after the backup was created, so it will need to be performed again after restoring the virtual machine from the backup.

CyberKelev · Answer

In Backup does not exist new added Disk in meanwhile. We should add this Disk again

Madbo · Answer

The correct answer is C. Add a data disk.

When you use the "Replace existing" option to restore a virtual machine from an Azure Backup, the entire virtual machine is replaced with the backup data, including the operating system disk and all data disks that were attached to the virtual machine at the time the backup was taken.

SIAMIANJI · Answer

Copy Budget.xls to Data.

RandomNickname · Answer

Agree with D;

A-C are all retained if replace existing is used as far as I can tell.

sardonique · Answer

as usual some questions are so badly formulated, with the purpose to check how crazy you are, trying to understand what IQ test these guys had in mind

rnd3131 · Answer

You need to ensure that all the changes to VM1 are restored.
I am the only one saying A? All changes are reverted by restoring backup, but the vm size you need to revert manual!

tashakori · Answer

C is right

Z_MU · Answer

Read "Replace existing" option from restore options in below article
https://learn.microsoft.com/en-us/azure/backup/backup-azure-arm-restore-vms#restore-options

Notice this line "Azure Backup takes a snapshot of the existing VM before replacing the disk. The snapshot is copied to the vault and retained in accordance with the retention policy."

tcoelho28 · Answer

"Copy a file named Budget.xls to a folder named Data" 
Is copy to a folder, no mention the folder is in data disk.
If wehe have the consideration the order the changes, the file is copy before the data disk is added.
To restore the VM from the backup you need add data disk.
