Full question →easymultiple choiceObjective-mapped
A research team needs to store thousands of PDF reports that vary in length and structure. The storage solution must allow flexible schema and support access from multiple programming languages via HTTP. Which data storage category best describes these reports?
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
Structured data
Structured data follows a fixed schema (e.g., relational tables), whereas PDF reports have no predefined schema.
B
Distractor review
Semi-structured data
Semi-structured data (e.g., JSON, XML) has some organizational properties, but PDFs are typically unstructured binary files.
C
Best answer
Unstructured data
Unstructured data has no predefined structure and is stored as files (e.g., PDFs, images). Azure Blob Storage is a common choice for such data.
D
Distractor review
Transactional data
Transactional data refers to records of events in OLTP systems, not the storage format of documents.
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
A data engineer needs to transform large datasets stored in Azure Data Lake Storage Gen2 using Python and Apache Spark. They want a serverless compute option that automatically scales and requires no cluster management. Which Azure service should they use?
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: Unstructured data — The PDF reports are unstructured data because they do not have a defined data model or schema, and they are stored as files. Blob storage is typically used for such data. Semi-structured data (like JSON) has some organizational properties (e.g., tags), while structured data follows a rigid schema. Transactional data refers to OLTP operations, not file storage.
