You have an Azure virtual machine named VM1 that contains the drives shown in the following table.
On VM1, you plan to install an app named App1. The data for App1 must be stored on a persistent data disk assigned to drive D.
You need assign the data disk to drive D.
What should you do on VM1 first?
To assign the data disk to drive D, you need to move the pagefile.sys to the Operating System drive (C:) first. The temporary storage drive (D:) currently holds the pagefile.sys, and changing the drive letter directly without moving the pagefile.sys would cause system instability or malfunction. Therefore, moving the pagefile.sys from drive D: to drive C: ensures that the temporary storage drive D: can be repurposed for the data disk of App1.
I think B. is the answer. First you need to move pagefile.sys and then change the drive letter. https://learn.microsoft.com/en-us/azure/virtual-machines/windows/change-drive-letter
