Full question →mediummultiple choiceObjective-mapped
Company A deploys several Linux virtual machines (VMs) across multiple Azure availability zones in the West US region. The VMs run a cluster application that needs to read and write data concurrently to a shared file system. The solution must support the Server Message Block (SMB) protocol and must be accessible from all zones with low latency. Which Azure storage service should the company use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Azure Files
Azure Files offers fully managed file shares accessible via SMB, which can be mounted by multiple VMs concurrently across availability zones, meeting the requirement for shared access.
B
Distractor review
Azure Blob Storage
Azure Blob Storage is an object storage solution for unstructured data. It does not natively support the SMB protocol or provide a file system mountable by multiple VMs for concurrent read/write operations.
C
Distractor review
Azure Managed Disks
Azure Managed Disks are page blobs that provide persistent block storage for a single VM. They cannot be attached to multiple VMs simultaneously, so they are not suitable for a shared file system.
D
Distractor review
Azure Queue Storage
Azure Queue Storage is a messaging service for asynchronous communication between application components. It does not provide a file system interface or support SMB.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Files — Azure Files provides fully managed file shares in the cloud that support the SMB protocol. These shares can be mounted concurrently by multiple VMs, including Linux VMs (using the SMB client), making it ideal for clustered applications that require shared access. The file shares are accessible across availability zones within the same region, offering low-latency access. The other options do not provide a shared SMB file system: Azure Blob Storage is object storage, Azure Managed Disks are block-level volumes that can only be attached to a single VM, and Azure Queue Storage is a messaging service.
