Full question →mediummultiple choiceObjective-mapped
A company has a legacy application that requires SMB (Server Message Block) file shares to store and access configuration files. They want to migrate this data to Azure without modifying the application. Which Azure storage solution should they 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
Distractor review
Azure Blob Storage
Azure Blob Storage is optimized for storing large amounts of unstructured object data, but it does not support the SMB protocol natively. The application would need to be modified to use a different access method (e.g., REST API).
B
Best answer
Azure Files
Azure Files offers fully managed cloud file shares that support the SMB protocol. It can be mounted directly by on-premises or cloud applications, allowing the legacy application to access files without modification.
C
Distractor review
Azure Queue Storage
Azure Queue Storage is a messaging service for storing and retrieving messages. It is not a file storage service and does not support SMB. It is used for decoupling components in distributed applications.
D
Distractor review
Azure Disk Storage
Azure Disk Storage provides persistent block storage for Azure Virtual Machines. It is not a shared file service and is typically attached to a single VM, not suitable for multiple application instances requiring shared access.
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.

Question 3
A data engineer needs to process raw clickstream data from multiple websites that is stored in Azure Blob Storage as JSON files. The processing must run automatically every hour, transform the data into a structured format for reporting, and handle schema changes in the source data without manual intervention. Which Azure service should be used?
Question 4
A data engineer is designing a data lake architecture in Azure. They plan to first ingest raw data from various sources into a landing zone in Azure Data Lake Storage Gen2. Then they will clean, validate, and deduplicate that data in a second zone. Finally, they will create aggregated, business-ready datasets in a third zone for analysts. This layered approach is known as which architecture?
Question 5

Question 6
A company collects customer feedback forms. Each form contains always-present fields like CustomerID and SubmissionDate, but also a free-text Comments field and optional fields like Rating or ProductCategory that vary between forms. How should this data be classified?
FAQ
Questions learners often ask
What does this DP-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 SMB file shares in the cloud, accessible via standard SMB protocol. This allows legacy applications to mount the share without code changes. Azure Blob Storage is object storage accessed via HTTP/HTTPS, not SMB. Azure Queue Storage is for messaging. Azure Disk Storage provides block-level storage for virtual machines.
