AZ-104 Implement and Manage Storage 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

  Why it's wrong here

  A full VM restore recreates an entire virtual machine from its virtual hard disks (VHDs), which has no bearing on Azure Files unless the file share is attached inside a VM disk. Even in that scenario, you would lose all post-snapshot changes to the VM and suffer downtime while the VM is powered down and rebuilt, which is disproportionate and risky compared to surgically restoring one Excel file. Azure Files storage is a managed PaaS service; its contents are not part of any VM's virtual hard disk, so a VM restore cannot even address the deleted file in the share.

  When this WOULD be correct

  When a question asks for recovering an entire virtual machine after a catastrophic failure, such as a VM crash or corruption, where all data and system state need to be restored from a backup.

• ✓

  A file-level restore from the backup recovery point

  Why this is correct

  Azure Backup for Azure Files supports granular item-level recovery directly from a recovery point. You can select the specific deleted Excel file in the backup vault's restore flow and either overwrite it in its original share or restore it to an alternate location without touching any other files or workloads. This is the intended mechanism for recovering a single file that was lost, because it reads the file content from the stored share snapshot and writes it back through the SMB/REST data plane, leaving the rest of the share intact.

• ✗

  A metric alert rule

  Why it's wrong here

  A metric alert rule is an Azure Monitor construct that watches numeric performance signals such as file share capacity, egress bytes, or transaction counts and fires a notification when a threshold is breached. It is a telemetry and notification mechanism only; it has no permissions or code path to interact with the file share's data plane or with Azure Backup's recovery point store. At best, an alert could tell you that the share capacity changed or that a deletion occurred retroactively, but it can never restore the file content or bring back the lost data. The restore requires a backup read operation, which alerts simply cannot perform.

  When this WOULD be correct

  When the question asks how to be notified if the file share's storage usage exceeds a threshold, a metric alert rule would be the correct answer.

• ✗

  A private endpoint

  Why it's wrong here

  A private endpoint, implemented via Azure Private Link, assigns a private IP address from your virtual network to the file share's storage account to keep traffic off the public internet. It strictly governs the network path and authentication plane, not the data recovery plane; the endpoint simply exposes the storage service at a private address. It has no awareness of backup recovery points, file snapshots, or the contents of the share, so it cannot resurrect a deleted Excel file. It might prevent an attack or restrict access, but it cannot undo an accidental deletion.

  When this WOULD be correct

  You need to ensure that backup data for an Azure file share is transferred over a private network, not the public internet. A private endpoint would be the correct choice to restrict access to the backup service to your virtual network.

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.
