AZ-104 Monitor and Maintain Azure Resources Practice Question
A user deleted one Excel file from a Windows Server VM that is protected by Azure Backup. The VM must keep running, and the administrator must restore only that file as quickly as possible. What should the administrator do?
⚠ Common exam trap
Watch out — candidates often assume a full VM restore is required for any file recovery, overlooking the Azure Backup File Recovery feature which provides granular, in-place restoration without disrupting the running VM.

Correct answer & explanation
✓
Use File Recovery from the Recovery Services vault, mount the recovery point, and copy back the deleted file.
Azure Backup for Azure VMs supports file-level recovery from recovery points without restoring the entire VM. The File Recovery feature mounts the recovery point as an iSCSI target on the VM, allowing the administrator to browse and copy the deleted Excel file directly. This is the fastest method because it avoids the overhead of a full VM restore or snapshot management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Restore the entire virtual machine from the most recent recovery point.
Why it's wrong here
Restoring the entire virtual machine from the most recent recovery point is a heavy-handed approach that would require redeploying the VM and likely deallocating it, causing downtime and potentially overwriting newer changes made on the production VM. This method treats the incident as a full VM failure rather than a single deleted file, and it could roll back the OS, applications, and other data to an older state. Azure Backup's File Recovery feature is explicitly designed to avoid this disruption by mounting only the needed recovery point and allowing selective file copy, so a full VM restore is unnecessarily destructive and slower.
When this WOULD be correct
This option would be correct if the question stated that the entire VM was corrupted or unavailable, and the administrator needed to restore the full VM to a working state, with no requirement to keep the current VM running.
- ✓
Use File Recovery from the Recovery Services vault, mount the recovery point, and copy back the deleted file.
Why this is correct
File Recovery is designed for this exact scenario. It mounts a backup recovery point so the administrator can browse the contents and copy back only the missing file, while the production VM continues running without a full restore.
- ✗
Fail over the VM by using Azure Site Recovery and then copy the file from the replica.
Why it's wrong here
Azure Site Recovery (ASR) is a disaster recovery service that replicates entire virtual machines to a secondary region for business continuity during regional outages, not for routine file-level recovery. Failing over would switch production traffic to the replica, change the VM's identity/IP addressing, and require a failback afterward—severe disruption for an otherwise healthy VM. ASR does not provide a granular browse-and-restore interface for individual files from backup recovery points; that capability belongs to Azure Backup, making ASR both architecturally and operationally wrong for this scenario.
When this WOULD be correct
If the question required recovering an entire VM after a regional outage with minimal data loss, and the goal was to quickly bring the VM online in another region, then failing over using Azure Site Recovery would be correct.
- ✗
Create a snapshot of the VM disk and restore the spreadsheet from the snapshot.
Why it's wrong here
Creating a VM disk snapshot captures the entire disk at a point in time, but snapshots are not integrated with Azure Backup recovery points and do not offer file-level restore. To retrieve the file, you would have to manually create a managed disk from the snapshot, attach it to another VM, mount the filesystem, and then locate and copy the file—a complex, time-consuming process. Additionally, a snapshot alone does not guarantee application-consistent state unless you specifically coordinate it with the application, and it does not leverage the Recovery Services vault's granular restore capabilities.
When this WOULD be correct
This option would be correct if the question asked for a method to restore a file from a VM that is NOT protected by Azure Backup, and the administrator needs a quick, point-in-time copy of the entire disk without impacting the running VM (e.g., using Azure Backup's application-consistent snapshots or manual snapshots).
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Use File Recovery from the Recovery Services vault, mount the recovery point, and copy back the deleted file.Correct answer▾
Why this is correct
File Recovery is designed for this exact scenario. It mounts a backup recovery point so the administrator can browse the contents and copy back only the missing file, while the production VM continues running without a full restore.
✗Restore the entire virtual machine from the most recent recovery point.Wrong answer — click to see why▾
Why this is wrong here
Restoring the entire VM from a recovery point is much slower than file-level recovery and would cause downtime, which contradicts the requirement to keep the VM running and restore only the deleted file as quickly as possible.
★ When this WOULD be the correct answer
This option would be correct if the question stated that the entire VM was corrupted or unavailable, and the administrator needed to restore the full VM to a working state, with no requirement to keep the current VM running.
Why candidates choose this
Candidates may think that restoring the entire VM is the only way to recover the file, not realizing that Azure Backup supports file-level recovery for Windows VMs, which is faster and less disruptive.
✗Fail over the VM by using Azure Site Recovery and then copy the file from the replica.Wrong answer — click to see why▾
Why this is wrong here
Azure Site Recovery is designed for disaster recovery and failover, not for granular file-level restore from backup. Failing over the VM would cause downtime and is much slower than using File Recovery.
★ When this WOULD be the correct answer
If the question required recovering an entire VM after a regional outage with minimal data loss, and the goal was to quickly bring the VM online in another region, then failing over using Azure Site Recovery would be correct.
Why candidates choose this
Candidates may confuse Azure Backup with Azure Site Recovery, or think that failover is a valid method to access a previous version of a file, not realizing it's intended for disaster recovery scenarios.
✗Create a snapshot of the VM disk and restore the spreadsheet from the snapshot.Wrong answer — click to see why▾
Why this is wrong here
Creating a snapshot of the VM disk and restoring the spreadsheet from it is slower and more complex than using File Recovery, as it requires stopping the VM or detaching the disk, and does not allow direct file-level restore from Azure Backup snapshots.
★ When this WOULD be the correct answer
This option would be correct if the question asked for a method to restore a file from a VM that is NOT protected by Azure Backup, and the administrator needs a quick, point-in-time copy of the entire disk without impacting the running VM (e.g., using Azure Backup's application-consistent snapshots or manual snapshots).
Why candidates choose this
Candidates may think snapshots are the fastest way to recover a file because they are familiar with taking snapshots for quick rollbacks, but they overlook that Azure Backup's File Recovery is specifically designed for instant file-level restore without disk manipulation.
