AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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
Restore options shown in Recovery Services vault:
- Create a new VM
- Replace existing VM
- Restore disks
- File Recovery
Incident: One configuration file was deleted from vm-web02, but the VM is still running and should remain unchanged.
Based on the exhibit, an administrator needs to recover one deleted configuration file from a running Azure VM without replacing the VM. Which restore option should be used?
Restore options shown in Recovery Services vault:
- Create a new VM
- Replace existing VM
- Restore disks
- File Recovery
Incident: One configuration file was deleted from vm-web02, but the VM is still running and should remain unchanged.
A
Create a new VM from the recovery point so the deleted file returns with a clean operating system.
Why wrong: Creating a new VM is unnecessary for a single file recovery and would be much more disruptive than needed. The existing VM must remain unchanged.
B
Restore disks and manually rebuild the VM afterward.
Why wrong: Restoring disks is appropriate for larger recovery scenarios, but it is too heavy for recovering one file. It also creates extra operational work the scenario does not require.
C
Use File Recovery to mount the recovery point and copy back the missing file.
File Recovery is designed for restoring individual files from a backup without replacing the live VM. It lets the administrator mount the recovery point, copy back the deleted file, and leave production running normally.
D
Replace the existing VM immediately to recover only one file.
Why wrong: Replacing the VM would be far more disruptive than necessary and could overwrite current changes. It is the wrong choice for a single missing file.

Correct answer & explanation
✓
Use File Recovery to mount the recovery point and copy back the missing file.
Azure VM File Recovery (part of Azure Backup) allows you to mount a recovery point as a drive on a running VM, browse the file system, and copy specific files back without restoring the entire VM or disks. This is the only option that recovers a single deleted configuration file without replacing or rebuilding the VM.
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 think a full disk restore or VM rebuild is required for file-level recovery, but Azure Backup's File Recovery feature is specifically designed for granular file recovery from a VM backup without VM replacement.

Scenario analysis trap
Restoring disks is appropriate for larger recovery scenarios, but it is too heavy for recovering one file. It also creates extra operational work the scenario does not require.
Detailed technical explanation
How to think about this question
Azure Backup's File Recovery feature uses iSCSI to mount the recovery point's virtual hard disk (VHD) as a local drive on the VM, allowing read-only access to the file system. The administrator can then copy the missing configuration file from the mounted snapshot back to the original location. This process leverages the Azure Backup service's ability to create application-consistent snapshots and mount them without impacting the running VM.

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.
