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. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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
Recovery Services vault > Backup item > vm-finance01
Restore points available: 3
Most recent recovery point: 2026-04-25 01:00 UTC
Requirement: restore C:\Data\Quarterly\budget.xlsx only
Based on the exhibit, a user accidentally deleted one file from the VM and you need to restore only that file without recovering the entire virtual machine. What should you use?

A
Run file recovery from the available recovery point.
Azure VM backup supports file-level recovery from a restore point. Because only one file is needed, file recovery is the least disruptive and most efficient choice. It mounts the recovery point and lets you copy back the missing file without restoring the entire VM or its disks.
B
Restore the entire VM to the original resource group.
Why wrong: A full VM restore would recover much more than required and could replace the existing VM. That is unnecessary when only one file must be retrieved.
C
Create a new backup policy with longer retention and wait for the next backup.
Why wrong: Changing retention does not recover the missing file immediately. The file already exists in a current recovery point, so waiting for a new backup wastes time.
D
Use Azure Monitor alerts to trigger an automatic file restore.
Why wrong: Alerts can notify operators about events, but they do not perform file-level restore operations. The recovery action must come from Azure Backup.

Correct answer & explanation
✓
Run file recovery from the available recovery point.
Azure Backup for Azure VMs supports file-level recovery from VM backup snapshots without restoring the entire VM. By selecting 'File Recovery' from the backup item's recovery point, you can mount the backup as a drive on the VM or a recovery machine, browse the file system, and copy the deleted file back to its original location. This avoids the overhead and downtime of a full VM restore.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'file recovery' with 'full VM restore' or assume that only a full restore can recover data, overlooking the granular file-level recovery capability built into Azure Backup.
Detailed technical explanation
How to think about this question
Azure Backup's file-level recovery leverages iSCSI to mount the VM's VHD from the recovery point as a local drive on the VM or a separate machine. The process uses the Azure Backup service to temporarily expose the snapshot over the network, allowing read-only access to the file system. This feature is available for Windows and Linux VMs, but requires the VM to be running (or an alternate machine with network access) to mount the iSCSI target.

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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
