Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
A retail company processes customer orders throughout the day. Each order involves inserting a new record into a database table, updating inventory counts, and deleting temporary cart data. At the end of each week, the company runs a query that aggregates all orders by product category and region to generate a sales report. Which of the following best describes these two workloads?
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
Order processing is OLAP; weekly reporting is OLTP
This reverses the definitions. OLTP handles many small transactions, not analytical queries. OLAP handles large aggregations, not high-frequency writes.
B
Distractor review
Order processing is batch processing; weekly reporting is streaming processing
Order processing occurs in real-time as transactions happen, not as a batch. The weekly report is a scheduled batch job, not continuous streaming.
C
Best answer
Order processing is OLTP; weekly reporting is OLAP
Order processing is transactional (OLTP) and the weekly report is analytical (OLAP). This is a correct distinction between the two common data workload patterns.
D
Distractor review
Both workloads are OLTP
The weekly sales report is an analytical query that aggregates data, which is not a transactional workload. OLTP is for day-to-day operations, not for heavy aggregation.
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 1
A data engineer needs to process streaming data from IoT devices and store the results in Azure Data Lake Storage for long-term analytics. The data must be processed in near real-time to detect anomalies and trigger alerts. Which Azure service should the engineer use for stream processing?
Question 2
A data engineer needs to query data stored in CSV files in Azure Data Lake Storage Gen2 using T-SQL in Azure Synapse Analytics, without loading the data into the database. Which feature should they use?
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: Order processing is OLTP; weekly reporting is OLAP — The order processing workload consists of many small transactions that insert, update, and delete records—this is a classic Online Transaction Processing (OLTP) workload. The weekly sales report query reads and aggregates large volumes of data across multiple dimensions, which is characteristic of Online Analytical Processing (OLAP). OLTP systems are optimized for fast transactional operations, while OLAP systems are optimized for complex queries and data analysis.
