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 finance department stores spreadsheets in an Azure file share. Yesterday a user deleted a subfolder tree, but other folders were modified after that point and must not be rolled back. The administrator wants to restore only the deleted subfolder tree to its state from yesterday. What should the administrator use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the Azure Files snapshot taken before the deletion and copy back only the required folders.
Option B is correct because Azure Files supports snapshot-based restore at the share level. By taking a snapshot before the deletion, the administrator can mount that snapshot as a read-only copy of the share, then copy back only the deleted subfolder tree without affecting any modifications made to other folders after the snapshot was taken. This meets the requirement of restoring only the deleted content while preserving later changes.
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.
✗
Restore the entire share from Azure Backup to the yesterday recovery point.
Why it's wrong here
This would revert the whole share and could overwrite valid changes made after the deletion.
✓
Use the Azure Files snapshot taken before the deletion and copy back only the required folders.
Why this is correct
A snapshot provides point-in-time data, letting the administrator restore only the deleted folder tree.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable blob soft delete on the storage account and then recover the folders.
Why it's wrong here
Blob soft delete applies to blobs, not Azure Files folders inside a file share.
✗
Create a new file share and use synchronization to merge the deleted content.
Why it's wrong here
Synchronization is not a point-in-time restore method and cannot precisely recover one deleted folder tree.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Azure Files snapshots with Azure Backup or blob soft delete, assuming any recovery mechanism can selectively restore without understanding that only snapshots allow granular copy-back without affecting current data.
Detailed technical explanation
How to think about this question
Azure Files snapshots are incremental point-in-time copies of the entire share, stored as read-only versions of the share at the moment of creation. They are managed via the Azure portal, PowerShell, or CLI, and can be mounted as a separate drive (e.g., using `net use` with the snapshot path) to allow granular file/folder copy operations. A common real-world scenario is recovering a single department folder from a snapshot while leaving other folders untouched, which avoids the overhead of a full restore and minimizes downtime.

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.
