AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
You need to allow recovery of previous versions of files stored in an Azure file share after accidental modification or deletion. Which feature should you configure?
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
✓
Share snapshots for Azure Files
Share snapshots for Azure Files capture point-in-time, read-only copies of the file share, allowing you to recover previous versions of files after accidental modification or deletion. This feature is specifically designed for Azure file shares, not for blobs, and does not require any additional infrastructure.
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.
- ✗
Blob versioning
Why it's wrong here
Blob versioning is for blob storage, not Azure file shares.
When this WOULD be correct
If the question asked about recovering previous versions of blobs in an Azure Blob Storage container after accidental modification or deletion, then blob versioning would be the correct feature to configure.
- ✓
Share snapshots for Azure Files
Why this is correct
Share snapshots enable point-in-time recovery for Azure file shares.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
A shared access signature
Why it's wrong here
A SAS delegates access and does not provide recovery points.
When this WOULD be correct
A question asking for a method to grant time-limited, delegated access to a specific file share for a third-party application, without sharing the storage account key, would have SAS as the correct answer.
- ✗
Storage account failover
Why it's wrong here
Failover changes the active region and does not provide file version recovery.
When this WOULD be correct
This option would be correct in a scenario where the question asks: 'You need to ensure that your storage account remains available during a regional outage. Which feature should you configure?'
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.
✓Share snapshots for Azure FilesCorrect answer▾
Why this is correct
Share snapshots enable point-in-time recovery for Azure file shares.
✗Blob versioningWrong answer — click to see why▾
Why this is wrong here
Blob versioning is a feature for Azure Blob Storage, not Azure Files. The question specifically asks about files in an Azure file share, which requires share snapshots for version recovery.
★ When this WOULD be the correct answer
If the question asked about recovering previous versions of blobs in an Azure Blob Storage container after accidental modification or deletion, then blob versioning would be the correct feature to configure.
Why candidates choose this
Candidates may confuse Azure Files with Azure Blob Storage, assuming both use blob versioning for version recovery, or they may not realize that Azure Files has its own snapshot feature.
✗A shared access signatureWrong answer — click to see why▾
Why this is wrong here
A shared access signature (SAS) provides delegated access to storage resources, not version recovery. It cannot restore previous file versions or protect against accidental modification/deletion.
★ When this WOULD be the correct answer
A question asking for a method to grant time-limited, delegated access to a specific file share for a third-party application, without sharing the storage account key, would have SAS as the correct answer.
Why candidates choose this
Candidates may confuse SAS with a recovery feature because it can be used to grant access to snapshots, but SAS itself does not enable versioning or recovery.
✗Storage account failoverWrong answer — click to see why▾
Why this is wrong here
Storage account failover is a disaster recovery feature that switches the primary region to a secondary region in case of a regional outage. It does not provide point-in-time recovery of individual file versions after accidental modification or deletion.
★ When this WOULD be the correct answer
This option would be correct in a scenario where the question asks: 'You need to ensure that your storage account remains available during a regional outage. Which feature should you configure?'
Why candidates choose this
Candidates may confuse failover with recovery capabilities, thinking that failover can restore previous file versions, or they may associate 'recovery' broadly with any disaster recovery feature.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Blob versioning (which is for Azure Blob Storage) with share snapshots for Azure Files, as both provide versioning-like capabilities, but they apply to different storage services and have distinct implementations.
Detailed technical explanation
How to think about this question
Share snapshots are incremental, meaning only the changes since the last snapshot are stored, optimizing storage costs. They can be managed via the Azure portal, Azure CLI, or REST API, and up to 200 snapshots can be created per share. In a real-world scenario, you can schedule snapshot creation using Azure Automation or a logic app to ensure regular recovery points without manual intervention.
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.
