The concept, in one picture
Try a real AZ-104 question
A Windows Server 2016 Azure VM in your subscription is protected by a daily Azure Backup policy with Instant Restore snapshots retained. The VM is hit by ransomware that encrypts its data, and you must recover a clean copy from a recovery point taken before the infection. Which restore action is the recommended, supported approach?
- ✓ Restore the recovery point to a brand-new Azure VM
- Overwrite the existing infected VM in place from the recovery point
- Restore the recovery point directly onto an on-premises Windows server
- Attach the recovery point as the OS disk of another running production VM in the subscription
For a compromised VM, Azure Backup's Create new VM restore option provisions a fresh Azure VM from a pre-infection recovery point, keeping the clean workload isolated from the infected resource — the recommended ransomware-recovery path. The Replace existing option does exist (supported for unencrypted managed disks), but it only swaps disks back onto the same compromised VM shell and risks reintroducing the infected state, so it is not the recommended approach here. Azure Backup restores Azure VM recovery points into Azure (a new VM or restored disks), not directly to an on-premises server. Mounting or attaching the recovery point to another running production VM would expose a healthy machine to the infected disk rather than delivering an isolated clean restore.
