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 deployment and then copy the file back

  Why it's wrong here

  Restoring the entire VM to a new deployment creates a full new VM from the chosen recovery point, requiring you to manage new IP addresses, rejoin domains, reconfigure application dependencies, and reroute production traffic before you can copy the one missing file back. This is a heavy, multi-step operation that takes tens of minutes to hours and incurs extra compute and storage costs, even though the original VM remains intact. It's valid for whole-VM corruption but is far more invasive than a targeted file recovery.

  When this WOULD be correct

  This option would be correct if the question required recovering the entire VM to a known good state, and the original VM could be taken offline or replaced. For example: 'A VM has been corrupted by malware and needs to be fully restored to a previous clean state. The VM can be shut down during recovery.'

• ✓

  Use the file recovery option from the Recovery Services vault for the relevant recovery point

  Why this is correct

  Azure Backup's File Recovery option allows you to mount a backup recovery point as an iSCSI drive directly on the Windows VM, letting you browse the snapshot and copy out just the missing file with standard file-copy tools. The VM stays online throughout the process, and no restore of the entire VM is needed. Because the recovery point is a point-in-time snapshot, you select the most recent point that contains the file, which is the least-disruptive and fastest method.

• ✗

  Trigger an Azure Site Recovery failover to a recovery region

  Why it's wrong here

  Azure Site Recovery is a disaster-recovery (DR) service that continuously replicates the whole VM to a secondary Azure region; invoking a failover there shifts the workload to the replica, but it does not perform file-level restoration and would leave the original VM with the file still missing. Failover also introduces downtime, requires IP/DNS reconfiguration, and may incur additional compute costs. It is designed for regional outages, not accidental file deletion.

  When this WOULD be correct

  An administrator needs to recover an entire Windows VM after a regional outage, and the VM must be brought online in a different Azure region with minimal data loss. In that scenario, triggering an Azure Site Recovery failover to the recovery region would be the correct approach.

• ✗

  Create a new backup policy with a shorter retention period and run the next scheduled backup

  Why it's wrong here

  A backup policy controls snapshot frequency and retention periods; creating a new policy with shorter retention does not retroactively restore data and can even cause existing recovery points to expire sooner. The next scheduled backup would not recover the deleted file—it would only create a new recovery point that still lacks the file, and the old recovery point containing the file could be pruned before you use it.

  When this WOULD be correct

  An administrator needs to reduce backup storage costs for a VM by decreasing retention duration for future backups, while keeping existing recovery points unchanged. The correct action would be to modify the backup policy to a shorter retention period and apply it to the VM.

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.
