You create a Recovery Services vault named Vault1. Given the resources in the subscription (as in the referenced table), which resources can you back up to Vault1 using Azure Backup?

The correct answer is AVDVM-0 and share1 only because Azure Backup supports backing up Azure Virtual Machines (AVDVM-0) and Azure Files (share1). Image1 and Image2 are Azure Compute Gallery images. While you can create backups of virtual machines that use these images, Azure Backup does not directly back up the images themselves as separate entities. You would back up the VM, not the image it was created from. Therefore, only the virtual machine and the file share are directly supported backup targets for a Recovery Services vault.
