AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: file Recovery mounts a recovery point as a local drive on the target VM.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
Backup item: vm-finance-03
Current status: Protected
Incident: One spreadsheet was deleted from C:\Reports\Q1\
Requirement: Restore only the deleted file
Constraint: The virtual machine must remain available to users during recovery
Based on the exhibit, which restore option should the administrator use to recover only the deleted file while keeping the VM online?
Backup item: vm-finance-03
Current status: Protected
Incident: One spreadsheet was deleted from C:\Reports\Q1\
Requirement: Restore only the deleted file
Constraint: The virtual machine must remain available to users during recovery
A
Restore the entire virtual machine to the latest recovery point.
Why wrong: A full VM restore is more disruptive than needed and can replace the entire machine state.
B
Use File Recovery from the Recovery Services vault.
File Recovery is designed for exactly this scenario: recovering one or more files or folders from a VM backup without restoring the whole virtual machine. The VM stays online, users can continue working, and the administrator mounts the recovery point to copy back only the missing spreadsheet. This minimizes downtime and avoids overwriting unrelated data on the VM.
C
Redeploy the VM from the original image.
Why wrong: Redeployment rebuilds the machine and would not selectively recover a single deleted file.
D
Disable backup protection and then re-enable it.
Why wrong: Turning backup off and on does not recover deleted files and could create an unnecessary gap in protection.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use File Recovery from the Recovery Services vault.
Option B is correct because Azure Backup's File Recovery feature allows you to mount a recovery point as a drive on the VM, enabling you to browse and restore individual files without affecting the running VM. This avoids the need to restore the entire VM or take it offline, which is essential for recovering only the deleted file while maintaining availability.
Key principle: File Recovery mounts a recovery point as a local drive on the target VM.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume restoring the entire VM is the only way to recover files, overlooking the File Recovery option that provides granular, online file-level restore without impacting the running VM.
Detailed technical explanation
How to think about this question
File Recovery works by mounting the VM's backup snapshots (stored as VHD files in the Recovery Services vault) as iSCSI targets on the VM, allowing read-only access to the file system. The administrator can then use standard file copy tools (e.g., robocopy, xcopy) to retrieve the deleted file from the mounted volume. This process leverages the Azure Backup agent's ability to expose point-in-time recovery points without requiring VM restart or downtime.
KKey Concepts to Remember
File Recovery mounts a recovery point as a local drive on the target VM.
The VM remains online and operational during File Recovery.
It is used for recovering specific files or folders, not the entire VM.
A script is downloaded from the Recovery Services vault to initiate the mount.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
File Recovery mounts a recovery point as a local drive on the target VM.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
