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.
Users in Branch01 access an Azure file share over SMB. Performance is poor because frequently used files are downloaded repeatedly across the WAN. You need to keep a local cache on a Windows Server in Branch01 while keeping Azure Files as the central file share. What should you deploy?
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
✓
Azure File Sync
Azure File Sync is the correct solution because it enables caching of Azure file shares on a Windows Server at the branch location, providing local access to frequently used files while keeping Azure Files as the central authoritative store. It uses a sync engine to maintain a local cache and leverages the SMB protocol for access, reducing WAN latency by serving files from the local server.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
Azure File Sync
Why this is correct
Azure File Sync provides a local cache on Windows Server while keeping Azure Files central.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Blob versioning
Why it's wrong here
Blob versioning is unrelated to SMB file-share caching.
When this WOULD be correct
A question requiring protection against accidental deletion or overwrite of blobs in Azure Blob Storage, where you need to preserve, restore, or manage earlier versions of blobs. For example: 'You need to enable the ability to restore a previous version of a blob that was overwritten. What should you configure?'
- ✗
Share snapshots
Why it's wrong here
Snapshots provide recovery points, not local branch caching.
When this WOULD be correct
A question asks: 'You need to protect an Azure file share from accidental deletion or corruption by enabling point-in-time restore capabilities. What should you configure?' In that case, share snapshots are the correct answer.
- ✗
A private endpoint
Why it's wrong here
A private endpoint can improve security posture but does not create a branch office cache.
When this WOULD be correct
A private endpoint would be correct if the question required securely connecting to Azure Files from an on-premises network without exposing the service to the public internet, such as when compliance mandates that all traffic must stay within the Azure backbone and not traverse the internet.
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.
✓Azure File SyncCorrect answer▾
Why this is correct
Azure File Sync provides a local cache on Windows Server while keeping Azure Files central.
✗Blob versioningWrong answer — click to see why▾
Why this is wrong here
Blob versioning maintains multiple versions of blobs in Azure Storage, but it does not provide local caching or sync capabilities for SMB file shares. It is designed for object-level version control, not for caching files locally to reduce WAN latency.
★ When this WOULD be the correct answer
A question requiring protection against accidental deletion or overwrite of blobs in Azure Blob Storage, where you need to preserve, restore, or manage earlier versions of blobs. For example: 'You need to enable the ability to restore a previous version of a blob that was overwritten. What should you configure?'
Why candidates choose this
Candidates may confuse versioning with caching or sync, thinking that maintaining multiple versions could somehow keep a local copy, or they may misapply blob storage concepts to file shares.
✗Share snapshotsWrong answer — click to see why▾
Why this is wrong here
Share snapshots provide point-in-time read-only copies of files for recovery, not local caching or synchronization. They do not keep a local cache on a Windows Server to reduce WAN traffic.
★ When this WOULD be the correct answer
A question asks: 'You need to protect an Azure file share from accidental deletion or corruption by enabling point-in-time restore capabilities. What should you configure?' In that case, share snapshots are the correct answer.
Why candidates choose this
Candidates may confuse share snapshots with caching or sync features, thinking snapshots can be used to store local copies, but snapshots are read-only and not designed for continuous local access.
✗A private endpointWrong answer — click to see why▾
Why this is wrong here
A private endpoint provides secure, private connectivity to Azure Files over the Microsoft backbone, but it does not create a local cache on-premises. The requirement is to cache files locally on a Windows Server in Branch01, which Azure File Sync does by syncing files to the server.
★ When this WOULD be the correct answer
A private endpoint would be correct if the question required securely connecting to Azure Files from an on-premises network without exposing the service to the public internet, such as when compliance mandates that all traffic must stay within the Azure backbone and not traverse the internet.
Why candidates choose this
Candidates may confuse private endpoints with improving performance, thinking that a private connection eliminates WAN latency, but it does not address the need for a local cache to avoid repeated downloads of frequently used files.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure File Sync with simply mounting an Azure file share via SMB or using a private endpoint, not realizing that File Sync specifically provides a local caching mechanism on a Windows Server to solve WAN latency issues.
Detailed technical explanation
How to think about this question
Azure File Sync uses a cloud tiering policy to keep only frequently accessed files locally on the Windows Server, while less-used files are tiered to the cloud, saving local storage. The sync process uses the FileSync agent and communicates over HTTPS, not SMB, to synchronize changes between the local server and the Azure file share. In a real-world scenario, this is ideal for branch offices with limited WAN bandwidth, as it ensures users have low-latency access to hot files without requiring full replication of the entire 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.
