A company stores customer names and addresses in a relational table, product descriptions as JSON files, and product images as JPEG files. Which of the following correctly classifies these data types from most structured to least structured?
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
Structured (customer table), Semi-structured (JSON), Unstructured (JPEG)
This is correct because a table with fixed columns is structured, JSON allows varying fields (semi-structured), and JPEG images have no internal structure (unstructured).
B
Distractor review
Structured (customer table), Unstructured (JSON), Semi-structured (JPEG)
JSON is not unstructured; it is semi-structured because it uses tags to organize data. JPEG images are unstructured, not semi-structured.
C
Distractor review
Semi-structured (customer table), Structured (JSON), Unstructured (JPEG)
A customer table is structured, not semi-structured. JSON is semi-structured, not structured.
D
Distractor review
Unstructured (customer table), Structured (JSON), Semi-structured (JPEG)
A customer table is structured, not unstructured. JSON is semi-structured, not structured. JPEGs are unstructured, not semi-structured.
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 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 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: Structured (customer table), Semi-structured (JSON), Unstructured (JPEG) — Structured data has a fixed schema, such as a database table with predefined columns. Semi-structured data, like JSON, has a flexible schema that can vary between records. Unstructured data, such as images (JPEG), has no predefined schema. Therefore, the correct order from most structured to least structured is: Structured (table), Semi-structured (JSON), Unstructured (JPEG).
