A logistics company ingests GPS coordinates from delivery trucks in real-time to update a live tracking dashboard. They also run a nightly job to aggregate the day's deliveries into a report stored in Azure SQL Database. Which statement correctly describes the data processing types used for 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
Best answer
GPS ingestion is stream processing; nightly aggregation is batch processing.
Correct. Real-time GPS data is ingested as a continuous stream, while the nightly job processes accumulated data in a batch.
B
Distractor review
GPS ingestion is batch processing; nightly aggregation is stream processing.
Incorrect. This reverses the definitions. GPS data arrives continuously (stream), and the nightly job runs on a fixed schedule (batch).
C
Distractor review
Both workloads are examples of stream processing.
Incorrect. The nightly aggregation is not continuous; it processes data in a single scheduled run, which is batch processing.
D
Distractor review
Both workloads are examples of batch processing.
Incorrect. The GPS ingestion is continuous and real-time, not processed in discrete batches.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: GPS ingestion is stream processing; nightly aggregation is batch processing. — Stream processing continuously handles data as it arrives, making it ideal for real-time GPS tracking. Batch processing processes data in scheduled, discrete chunks, which fits the nightly aggregation of daily delivery data. The GPS ingestion is stream processing, and the nightly aggregation is batch processing.
