You have an Azure VM named VM1 running Windows Server 2019 deployed with default drive settings. Signed in as User1 you create files on C:, create files on D:, change the screen saver timeout, and change the desktop background. You plan to redeploy VM1. Which of these changes will be lost after redeploy?

When you redeploy an Azure VM, it moves the VM to a different host within the Azure infrastructure. This process preserves the operating system disk (C: drive) and any data disks (like D:), but it resets the VM's state and configuration that are not persisted to these disks. The C: drive, being the OS disk, retains all its files. The D: drive, which is a temporary storage drive on Azure VMs, is reinitialized during a redeployment, meaning any data stored there will be lost. Screen saver timeouts and desktop backgrounds are settings stored within the operating system on the C: drive and are therefore preserved.
