AZ-104 Monitor and Maintain Azure Resources Practice Question

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 VM to a new instance so the deleted file comes back automatically.

  Why it's wrong here

  Restoring the entire VM to a new instance would create a full copy of the VM from the recovery point with the deleted file present, but it requires keeping both the original and restored VMs running, which is costly and can cause name or IP conflicts. You would then have to manually migrate the file and shut down or decommission resources, and any data changed on the original VM after the recovery point would not appear on the new instance. This approach is far more disruptive and expensive than using file-level restore.

  When this WOULD be correct

  If the question required recovering a VM that is completely corrupted or unavailable, and the goal is to restore the entire system to a new VM for testing or replacement, then restoring the entire VM to a new instance would be correct.

• ✓

  Perform a file-level restore from the recovery point and copy only the missing file back.

  Why this is correct

  File-level restore is the correct Azure Backup workflow when only a specific file or folder must be recovered. The administrator mounts the recovery point, browses the backed-up file system, and copies back the missing file without replacing disks or redeploying the VM. This keeps the running server intact and minimizes recovery time and operational risk. It is the least disruptive way to recover a single deleted file.

• ✗

  Restore the managed disks and replace the existing disks on the running VM.

  Why it's wrong here

  Restoring the managed disks and replacing them on the running VM would first require stopping and deallocating the VM to detach the current disks, then reattaching the restored disks—this replaces the entire OS and data disk state with the recovery point, discarding any changes written since that point. It also carries a risk of drive letter mismatches or boot issues. A single-file recovery should never require a disk swap when the Azure Backup vault already exposes the recovery point's file system.

• ✗

  Use Azure Monitor logs to reconstruct the file because the backup vault stores telemetry.

  Why it's wrong here

  Azure Monitor logs collect metrics, diagnostics, and activity data from resources, not file-system snapshots or user-data content; the backup vault stores recovery points, not telemetry, and there is no query or reconstruction capability that can rebuild a deleted file from log entries. Even if there were log artifacts, they would not include the binary contents of a deleted Excel file. Therefore, relying on Monitor logs for file recovery is technically impossible.

  When this WOULD be correct

  If the question asked how to investigate the cause of a VM performance issue or to analyze historical CPU/memory usage, Azure Monitor logs would be the correct tool to query telemetry data.

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.
