- A
Azure Blob Storage with a private container.
Why wrong: Blob Storage is object storage, not a file system. It does not support concurrent file locking or standard file-sharing protocols like SMB, making it unsuitable for shared file access by VMs.
- B
Azure NetApp Files.
Why wrong: Azure NetApp Files is a high-performance file storage service, but it is more expensive and typically used for specialized workloads (e.g., HPC). For standard file sharing with Microsoft Entra ID, Azure Files is more cost-effective and simpler.
- C
Azure Files shares.
Azure Files provides fully managed SMB and NFS file shares that can be accessed by multiple VMs concurrently. It supports Microsoft Entra ID-based authentication and authorization, making it ideal for shared file access.
- D
Azure Disk Storage with shared disks.
Why wrong: Azure shared disks allow attaching a managed disk to multiple VMs, but they are typically used for clustered applications (e.g., SQL Server FCI) and require cluster-aware file systems. They are not designed for general file sharing and do not integrate with Microsoft Entra ID directly for authentication.
Quick Answer
The answer is Azure Files shares, because they provide fully managed SMB and NFS file shares designed for concurrent access by multiple Azure virtual machines with low latency, while natively supporting Microsoft Entra ID authentication over SMB. This integration allows you to enforce granular access control using both RBAC roles and NTFS ACLs, making Azure Files the only shared storage solution that meets the requirement for identity-based authentication without additional infrastructure. On the AZ-204 exam, this scenario tests your ability to differentiate between Azure Files, Azure Blob Storage, and Azure NetApp Files—a common trap is choosing Blob Storage for shared file access, but Blob lacks native SMB protocol support and Entra ID authentication for concurrent VM mounts. Remember the memory tip: “Files for files, Blob for objects”—if multiple VMs need to mount a shared, frequently updated file system with Entra ID, always pick Azure Files.
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure 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.
You are developing a solution that requires multiple Azure virtual machines to access the same set of files concurrently. The files are updated frequently and must be accessible with low latency. You need to choose a shared storage solution that integrates with Microsoft Entra ID (Microsoft Entra ID) for authentication. Which Azure storage solution should you use?
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 Files shares.
Azure Files shares provide fully managed SMB and NFS file shares that can be accessed concurrently by multiple Azure VMs with low latency. They support identity-based authentication using Microsoft Entra ID (formerly Azure AD) over SMB, enabling granular access control via RBAC and NTFS ACLs. This makes Azure Files the correct choice for a shared, frequently updated file store requiring Entra ID integration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Azure Disk Storage with shared disks.
Why it's wrong here
Azure shared disks allow attaching a managed disk to multiple VMs, but they are typically used for clustered applications (e.g., SQL Server FCI) and require cluster-aware file systems. They are not designed for general file sharing and do not integrate with Microsoft Entra ID directly for authentication.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure NetApp Files (which supports SMB/NFS but not native Entra ID auth) with Azure Files (which does support Entra ID auth), or they mistakenly think Blob Storage can serve as a file share with low-latency concurrent access.
Detailed technical explanation
How to think about this question
Azure Files leverages the SMB 3.0 protocol with encryption in transit, and when configured with Microsoft Entra Domain Services or on-premises AD DS, it enables Kerberos-based authentication. The integration allows assigning RBAC roles like 'Storage File Data SMB Share Reader' to users/groups, and NTFS ACLs are preserved on the file share. In a real-world scenario, this is ideal for lift-and-shift applications that require Windows file shares with existing AD-based permissions, avoiding the need to refactor to blob storage.
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.
