You have an Azure virtual machine named VM1 that you use for testing. VM1 is protected by Azure Backup.

You delete VM1.

You need to remove the backup data stored for VM1.

What should you do first?

A. Delete the Recovery Services vault.
B. Delete the storage account.
C. Stop the backup

D. Modify the backup policy.

Explanation:
Azure Backup provides backup for virtual machines — created through both the classic deployment model and the Azure Resource Manager deployment model — by using custom-defined backup policies in a Recovery Services vault.

With the release of backup policy management, customers can manage backup policies and model them to meet their changing requirements from a single window. Customers can edit a policy, associate more virtual machines to a policy, and delete unnecessary policies to meet their compliance requirements.

Incorrect Answers:
B: You can’t delete a Recovery Services vault if it is registered to a server and holds backup data. If you try to delete a vault, but can’t, the vault is still configured to receive backup data.
