DP-900 Describe core data concepts Practice Question
This DP-900 practice question tests your understanding of describe core data concepts. 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.
A company receives customer order data from its online store in a CSV file. Each line contains fields like OrderID, CustomerName, Product, Quantity, and OrderDate. This data is best described as:
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Structured data
A is correct because the CSV file contains data that conforms to a strict tabular schema with predefined columns (OrderID, CustomerName, Product, Quantity, OrderDate) and consistent data types per column. This rigid, row-and-column format with a fixed schema is the defining characteristic of structured data, which can be directly loaded into a relational database or Azure SQL Database without transformation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Structured data
Why this is correct
Correct because the CSV file has a fixed schema with consistent fields per record, making it structured.
Clue confirmation
The clue word "best" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Semi-structured data
Why it's wrong here
Semi-structured data uses tags or markers but does not enforce a rigid schema; CSV has a rigid schema.
✗
Unstructured data
Why it's wrong here
Unstructured data lacks a predefined data model; CSV files have a well-defined structure.
✗
Transactional data
Why it's wrong here
Transactional data is a type of structured data, but the question asks for the broad classification, not the use case.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'transactional data' (a workload type) with 'structured data' (a format classification), leading them to pick D because the data describes orders, even though the question explicitly asks about the data's format, not its business purpose.
Detailed technical explanation
How to think about this question
Under the hood, structured data like CSV relies on a fixed schema enforced at write time, often with data type constraints (e.g., OrderID as integer, OrderDate as datetime). In Azure, this data can be ingested directly into Azure SQL Database or Azure Synapse Analytics using PolyBase or COPY INTO, leveraging the schema-on-write paradigm. A subtle behavior: CSV files can sometimes be misinterpreted as semi-structured if they contain quoted fields with embedded delimiters, but the schema remains fixed per RFC 4180.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
