The screenshot shows the Schedule Backup Wizard (Files and Folders), which is the Microsoft Azure Recovery Services (MARS) agent experience. This is file/folder backup to a Recovery Services vault, not an
"Azure VM backup" policy-based backup. In Microsoft's Azure Backup guidance, the MARS agent protects files and folders on a Windows machine by uploading encrypted backup data to the Recovery Services vault.
The encryption is controlled by a customer-managed passphrase, and Azure does not store that passphrase.
Because MARS backups are agent-based, restore is not limited to the original VM or to the VM's region.
Microsoft documentation for MARS restore describes restoring to the original location or to an alternate location, including another server, as long as the target machine is registered to the same vault and you provide the same passphrase used to encrypt the backups. The presence of VM2 in West US does not block restore for MARS-protected files/folders; region coupling is a constraint for Azure VM backup (vault and VM must be in the same region), not for MARS agent file/folder backup.
So, after redeploying or on another VM, you install and register the MARS agent to Vault1, then perform a restore of Folder1 using the correct passphrase-VM2 is a valid restore target.

Scenario Overview:
You have a Windows Server 2019 virtual machine (VM1) that has been created in Azure but is currently stopped (deallocated), as indicated by the exhibit (typical of this question from the AZ-104 pool). You need to enable Desired State Configuration (DSC) on this VM.
Understanding Azure Desired State Configuration (DSC)
Azure Desired State Configuration (DSC) is a management platform used to define and maintain configuration consistency for Azure virtual machines and other systems. In Azure, DSC can be managed via Azure Automation State Configuration, or locally using PowerShell DSC on the virtual machine.
To enable DSC on an Azure VM:
The VM must be running and accessible so that the DSC extension can be installed.
The Azure VM Agent must be operational (it runs only when the VM is started).
Configuration scripts or extensions (like Microsoft.Powershell.DSC) can only be applied to an active VM.
Why "Start VM1" is the Correct First Step
From the Microsoft Azure Administrator documentation (PowerShell DSC Extension for Azure VMs):
"Before you can enable the Azure Desired State Configuration extension on a virtual machine, the VM must be in the running state. The Azure VM Agent communicates with Azure to install and configure the DSC extension, and this agent only runs when the VM is powered on." This means that if VM1 is stopped (deallocated), Azure cannot deploy or enable the DSC extension, because it requires the VM to be active and connected to the Azure platform fabric.
Why the Other Options Are Incorrect
A). Configure a DNS name for VM1:
DNS naming allows external or internal connectivity but is not a prerequisite for enabling DSC. DSC configuration relies on the Azure VM Agent, not on DNS name resolution.
C). Capture a snapshot of VM1:
Snapshots are used for backup or replication, not for enabling configuration management features such as DSC.
D). Connect to VM1:
You cannot connect to VM1 (RDP/SSH) until it is started. Starting the VM is a prerequisite before any configuration management operation.
Key Documentation Reference (Microsoft Learn):
"The PowerShell Desired State Configuration (DSC) extension for Windows is used to configure Windows VMs. The extension requires the VM to be running so the Azure VM Agent can install and apply configurations."

Explanation:

On January 15, 2021, App1 will have only one backup in storage. Yes, this is correct. According to the table, App1 has a backup every 1 day, starting from January 6, 2021, with a retention of 0 days. This means that each backup will be deleted after 0 days, or as soon as the next backup is created. Therefore, on January 15,
2021, App1 will have only one backup in storage, which is the one created on that day1.
On February 6, 2021, you can access the backup of the App2 test slot from January 15, 2021. No, this is not correct. According to the table, App2 has a backup every 1 day, starting from January 6, 2021, with a retention of 30 days. This means that each backup will be deleted after 30 days, or when the storage limit is reached. However, the table also shows that App2 has a setting of "Keep at least one backup" set to Yes. This means that the oldest backup will be retained even if it exceeds the retention period or the storage limit2.
Therefore, on February 6, 2021, you can access the backup of the App2 test slot from January 6, 2021, but not from January 15, 2021.
On January 15, 2021, you can restore the App2 production slot backup from January 6 to the App2 test slot. Yes, this is correct. According to the web search results, you can restore a backup by overwriting an existing app or by restoring to a new app or slot3. You can also restore a backup from a different slot or app as long as they are in the same subscription and region4. Therefore, on January 15, 2021, you can restore the App2 production slot backup from January 6 to the App2 test slot.
