Full question →easymultiple choiceObjective-mapped
A ride-sharing company processes trip requests from customers. Each trip is recorded as a single transaction that updates the driver's status, calculates the fare, and logs the ride. At the end of each month, the company runs reports that aggregate millions of trips to determine average wait times and revenue per driver. Which pair of terms best describes these two distinct 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
Best answer
OLTP and OLAP
Correct. OLTP handles the individual trip transactions, while OLAP handles the monthly reporting and aggregation.
B
Distractor review
Batch processing and stream processing
Incorrect. Batch processing processes data in large chunks at scheduled times, and stream processing handles continuous data in real-time. Here, trip requests are processed immediately (like OLTP), not as a stream, and monthly reports are batch-like but the term OLAP is more precise.
C
Distractor review
ETL and ELT
Incorrect. ETL and ELT refer to data pipeline patterns for moving and transforming data, not the nature of the workloads themselves.
D
Distractor review
Relational and non-relational
Incorrect. Relational and non-relational refer to data storage models, not workload types.
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: OLTP and OLAP — The first workload—processing each trip request individually with immediate updates—is an Online Transaction Processing (OLTP) workload. It is characterized by many concurrent small transactions that require fast response times and ACID properties. The second workload—aggregating millions of trip records to generate monthly reports—is an Online Analytical Processing (OLAP) workload. OLAP involves complex queries that scan large volumes of data to derive business insights. These two workload types often require different database architectures and optimizations.
