- A
Restore the entire storage account from an account-level backup.
Why wrong: That would be too broad and would recover far more data than the scenario requires.
- B
Use a file share snapshot and copy the needed folders back from it.
Azure Files snapshots capture point-in-time versions of a file share. By using the snapshot, the administrator can browse the earlier state and copy back only the deleted folders, which avoids restoring the entire share and minimizes impact on current data. This is the right operational recovery method when you need granular recovery of file content after accidental deletion.
- C
Enable blob versioning on the storage account and recover the folders from versions.
Why wrong: Blob versioning applies to blobs, not to Azure file shares mounted through Azure Files.
- D
Create a shared access signature with read permissions and use it to recover the folder tree.
Why wrong: A SAS controls access, but it does not create a previous point-in-time copy for recovery.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. 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 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?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use a file share snapshot and copy the needed folders back from it.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Azure Files with Azure Blob Storage and incorrectly assume blob versioning or blob-level features apply to file shares, or they think a SAS token can somehow restore deleted data, when in fact only file share snapshots provide the necessary point-in-time, granular recovery for Azure Files.

Detailed technical explanation
How to think about this question
Azure file share snapshots are differential snapshots that capture the state of the file share at a given point in time, using copy-on-write technology. They are accessible via the SMB protocol (mounting as \\storageaccount.file.core.windows.net\share?snapshot=<DateTime>) or via REST APIs, allowing administrators to browse and copy individual files or folders. Snapshots are cost-effective because they only store the changes since the last snapshot, and they are retained until explicitly deleted, making them ideal for self-service point-in-time recovery without requiring a full backup infrastructure.
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.
