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.

• ✗

  A full VM restore to replace the existing virtual machine.

  Why it's wrong here

  Performing a full VM restore from a Recovery Services vault recovery point would replace the entire operating system and data disks, reverting every file change made after that backup and likely causing an outage or requiring VM recreation. For a single spreadsheet deletion, this is disproportionately invasive and risks overwriting unrelated current data, whereas file-level recovery mounts the same recovery point and lets you copy exactly the deleted file without touching the running VM. Azure Backup explicitly provides file-level recovery to avoid the downtime and data loss inherent in full VM restores.

  When this WOULD be correct

  This option would be correct if the question specified that the entire VM is corrupted or unavailable, and the goal is to restore the whole system to a previous state, not just a single file.

• ✓

  The file recovery process from the Recovery Services vault recovery point.

  Why this is correct

  Azure Backup supports file-level recovery by mounting a selected recovery point and allowing the administrator to copy out individual files or folders. This is the best option when the goal is to restore one deleted spreadsheet without replacing the entire virtual machine. It minimizes disruption and avoids overwriting other current VM data that was not affected.

• ✗

  Blob rehydration from Archive tier in the storage account.

  Why it's wrong here

  Blob rehydration from the Archive tier is a storage-level operation that changes the access tier of a block blob, not a mechanism to recover deleted files from a VM's disk. A Windows VM's disk is stored as a page blob, which is not eligible for Archive tier rehydration, and even if the underlying blob were accessible, rehydration would not expose the file system hierarchy or resurrect a deleted spreadsheet. This option confuses Azure Storage blob lifecycle management with Azure Backup's mount-and-copy file recovery, which operates on recovery points, not on storage access tiers.

  When this WOULD be correct

  An administrator needs to restore a large dataset stored as blobs in an Azure Storage account that has been moved to the Archive tier to reduce costs. The correct action would be to rehydrate the blobs to a hot or cool tier before accessing them.

• ✗

  A restore point collection operation in Azure Compute.

  Why it's wrong here

  Restore point collections in Azure Compute are API-level snapshot groups that capture application-consistent VM state, primarily for custom automation or dev/test scenarios. They do not integrate with the Recovery Services vault's backup chain, and Azure provides no built-in process to mount a restore point collection as a file share to copy out a single deleted spreadsheet. Azure Backup's file recovery, by contrast, creates a temporary mount of a backup recovery point, which is the only supported Azure-native method to recover individual files from a backed-up VM.

  When this WOULD be correct

  This option would be correct if the question asked: 'An administrator needs to create a custom restore point for a set of Azure VMs to be used for application-consistent recovery. What should be used?'

Option-by-option analysis

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.
