- A
A file share snapshot, because it captures a point-in-time copy of the share for granular recovery.
A snapshot is the right recovery tool when you need a point-in-time copy of an Azure file share and want to restore only a specific file. It allows granular recovery without rolling back the entire share, which keeps the impact small and the process simple. This is a common operational use of Azure Files snapshots.
- B
A storage account access key, because it can retrieve deleted files from any share version.
Why wrong: An access key controls authorization, not file recovery. It cannot restore deleted file content or create point-in-time copies.
- C
An Azure VM snapshot, because it captures the file share state automatically.
Why wrong: VM snapshots protect the VM's disks, not an Azure file share. They are the wrong recovery mechanism for a file-share-only deletion.
- D
A private endpoint to the file share, because it enables restore operations.
Why wrong: A private endpoint changes network access to the file share, but it does not provide backup or restore capability for deleted files.
Quick Answer
The answer is a file share snapshot, which is the correct choice because it captures a point-in-time, read-only copy of the Azure file share, enabling granular recovery of individual files without restoring the entire share or relying on a vault-based backup job. When a critical document is accidentally deleted, you simply mount a previous snapshot, locate the deleted file, copy it, and paste it back into the live share—no full restore or Azure Backup vault involvement is needed. On the AZ-104 exam, this question tests your understanding of native Azure Files recovery features versus backup solutions like Azure Backup, with a common trap being to select a restore from a Recovery Services vault, which is unnecessary for single-file recovery. Remember the memory tip: “Snapshot saves single files; vaults restore volumes.”
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage.

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.
An employee accidentally deletes a critical document from an Azure file share. You need to restore only that file to its earlier state without restoring the entire share or using a vault-based backup job. Which feature should you use?

Correct answer & explanation
A file share snapshot, because it captures a point-in-time copy of the share for granular recovery.
File share snapshots are point-in-time, read-only copies of Azure file shares that allow you to recover individual files or folders without restoring the entire share. When a file is accidentally deleted, you can mount a previous snapshot, copy the deleted file from it, and restore it to the live share—no vault-based backup job or full share restore required.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗

Why it's wrong here

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse file share snapshots with Azure Backup (vault-based recovery) or assume that access keys or private endpoints can somehow restore deleted files, when in fact only snapshots provide the granular, point-in-time restore capability for individual files.
Detailed technical explanation
How to think about this question
Azure file share snapshots are implemented using the Azure Files REST API's Snapshot property, which creates a differential copy at the file system level. Under the hood, each snapshot stores only the changes since the previous snapshot, making them space-efficient. In a real-world scenario, you can mount a snapshot via the `net use` command with the `snapshot` parameter (e.g., `net use Z: \\storageaccount.file.core.windows.net\share /snapshot:2025-03-15T12:00:00.0000000Z`) to browse and recover individual files without affecting the live share.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Same concept, more angles
3 more ways this is tested on AZ-104
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A user accidentally deleted a folder tree from an Azure file share. The administrator needs to restore only the deleted folders to the state they had yesterday, not roll back the whole share. Which feature should be used?
medium- A.Restore the entire storage account from an account-level backup.
- ✓ B.Use a file share snapshot and copy the needed folders back from it.
- C.Enable blob versioning on the storage account and recover the folders from versions.
- D.Create a shared access signature with read permissions and use it to recover the folder tree.
Why B: Azure file share snapshots provide a point-in-time, read-only copy of the share. By mounting a snapshot taken yesterday, the administrator can browse the folder tree and copy only the deleted folders back to the live share, restoring them without affecting other data. This is the only option that allows granular, folder-level recovery without rolling back the entire share or storage account.
Variation 2. A user accidentally deleted a nested folder tree from an Azure file share yesterday. Other folders were modified after the deletion and must not be rolled back. The administrator wants to restore only the deleted folder tree. What is the best recovery method?
medium- ✓ A.Use a file share snapshot and copy the deleted folder tree back into the live share.
- B.Delete the current share and restore the whole share from the most recent backup.
- C.Change the share’s access tier from Hot to Cool and then refresh the folder view.
- D.Enable soft delete for blobs in the same storage account and recover the folder from there.
Why A: Azure file share snapshots provide a point-in-time, read-only copy of the entire file share. By mounting a snapshot taken before the accidental deletion, the administrator can browse the snapshot's directory structure and copy only the deleted folder tree back into the live share. This approach restores the lost data without affecting any other files or folders that were modified after the snapshot was taken, meeting the requirement to avoid rolling back other changes.
Variation 3. An employee accidentally deletes several folders from an Azure file share. The administrator must recover only those folders from yesterday, not roll back the whole share. What should the administrator use?
easy- ✓ A.The latest Azure file share snapshot
- B.The storage account access key
- C.A shared access signature
- D.A private endpoint to the storage account
Why A: Azure file share snapshots capture the state of the share at a point in time. By mounting a snapshot taken yesterday, the administrator can browse the snapshot's directory structure and copy only the deleted folders back to the live share, without affecting other files. This provides granular recovery without rolling back the entire share.
