Full question →easymultiple choiceObjective-mapped
A manufacturing company stores two types of data: (1) real-time sensor readings from production machines used to monitor current machine status, and (2) historical daily production summaries used by managers to identify trends over months. Which statement accurately describes these 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
Sensor readings are an OLAP workload; daily summaries are an OLTP workload.
OLAP is for analytics on large datasets, not for high-frequency transactional inserts.
B
Best answer
Sensor readings are an OLTP workload; daily summaries are an OLAP workload.
Sensor readings are frequent transactions (OLTP), daily summaries are analytical (OLAP).
C
Distractor review
Sensor readings are a NoSQL workload; daily summaries are a relational workload.
The workload type depends on the access pattern, not necessarily the data store technology.
D
Distractor review
Sensor readings are a batch workload; daily summaries are a real-time workload.
Sensor readings are real-time; daily summaries are batch.
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: Sensor readings are an OLTP workload; daily summaries are an OLAP workload. — This question distinguishes between OLTP (Online Transaction Processing) and OLAP (Online Analytical Processing) workloads. Real-time sensor readings are transactional in nature—each reading is a small, frequent insert/update operation requiring quick response times. Historical daily summaries support analytical queries that aggregate large amounts of data over time. OLTP is optimized for many short online transactions, while OLAP is optimized for complex queries on large datasets. Option A incorrectly reverses the concepts. Options C and D describe unrelated characteristics.
