The answer is Azure Backup file-level restore, which is the correct choice because it allows you to mount a recovery point as an iSCSI drive directly on the VM or another machine, enabling you to browse and copy individual files without restoring the entire VM. This feature is specifically designed for granular recovery scenarios like a single deleted file, avoiding the time and resource overhead of a full VM restore. On the Microsoft Azure Solutions Architect Expert AZ-305 exam, this tests your understanding of Azure Backup’s recovery options and the distinction between full VM restore, file recovery, and alternate location recovery—a common trap is confusing file recovery with restoring files from Azure Backup for Azure Files or using Azure Site Recovery. Remember the memory tip: “Mount, don’t mountaineer”—you mount the recovery point as a drive to pick just one file, not restore the whole mountain of the VM.
AZ-305 Design business continuity solutions Practice Question
This AZ-305 practice question tests your understanding of design business continuity solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company uses Azure Backup to protect their critical Azure VMs. An administrator accidentally deleted a file from one of the VMs. They need to restore that specific file quickly without restoring the entire VM. Which Azure Backup feature should they use?
Why wrong: Full VM restore would restore the entire VM, which is slower and not needed for recovering a single file.
B
Azure Backup file recovery
Azure Backup file recovery allows you to mount a recovery point as a drive and copy specific files, meeting the requirement for quick file-level restore.
C
Azure Site Recovery
Why wrong: Azure Site Recovery is used for disaster recovery and orchestrated failover, not for restoring individual files from backup.
D
Azure Storage snapshots
Why wrong: Storage snapshots are separate from Azure Backup and require manual management; they do not provide the same integration and policy-based protection as Azure Backup.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Backup file recovery
Azure Backup's file recovery feature allows you to mount a recovery point as a drive on the VM (or another machine) using iSCSI, enabling you to browse and copy individual files without restoring the entire VM. This is the correct choice because it meets the requirement for a quick, granular restore of a single deleted file.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure Backup full VM restore
Why it's wrong here
Full VM restore would restore the entire VM, which is slower and not needed for recovering a single file.
✓
Azure Backup file recovery
Why this is correct
Azure Backup file recovery allows you to mount a recovery point as a drive and copy specific files, meeting the requirement for quick file-level restore.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Azure Backup's file recovery with Azure Site Recovery, thinking both provide granular restore, but Site Recovery is for replication and failover, not for point-in-time file recovery from backups.
Detailed technical explanation
How to think about this question
Azure Backup file recovery works by mounting the VM's VHD from the recovery point as an iSCSI target on the VM or a recovery machine. The iSCSI initiator on the target machine connects to the snapshot, presenting the disk as a local drive, allowing file copy operations. This process uses the Azure Backup vault's metadata and the VM's guest OS to ensure consistent mounts, and it supports both Windows and Linux VMs.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Variation 1. A company needs to back up an Azure virtual machine that runs a file server. They want to restore individual files quickly without restoring the entire VM. Which backup option should they use?
easy
A.Azure File Sync with cloud tiering.
B.Azure Backup using MARS agent with file and folder backup.
✓ C.Azure Backup for Azure VMs with file-level restore.
D.Azure Backup for Azure VMs with instant restore.
Why C: Option B (Azure Backup with file-level restore) allows restoring individual files. Option A (VM backup) is whole VM. Option C (Azure Files sync) is backup, not restore. Option D (snapshots) not integrated.
Variation 2. A company uses Azure Backup to protect on-premises Windows servers and Azure VMs. They need to restore a file from a backup of an Azure VM that was deleted three months ago. The backup policy retains daily backups for 30 days and weekly backups for 12 months. What is the CORRECT way to restore the file?
easy
A.Azure Backup does not support file-level restore for Azure VMs; restore the entire disk
B.Restore the entire VM from a weekly recovery point and then copy the file
C.Use the 'Restore to a new VM' option and select the file during the restore process
✓ D.Use the file-level recovery option to mount the recovery point as a drive and copy the file
Why D: Option C is correct because Azure Backup allows file-level recovery from Azure VM backups. You can mount the recovery point as a drive and copy the file. Option A is wrong because you cannot restore a file from a backup of a deleted VM by restoring the entire VM; that would be overkill and may not be possible if the VM is deleted. Option B is wrong because Azure Backup does not directly support restoring to a different VM without first restoring the disk. Option D is wrong because file-level restore is supported for Azure VMs.
