Full question →hardmultiple choiceObjective-mapped
A software-as-a-service (SaaS) provider hosts a multi-tenant application with a separate database for each tenant. They anticipate scaling to thousands of tenants and want to minimize cost while allowing tenants to share resources flexibly. Which Azure SQL offering is most suitable?
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
Azure SQL Database elastic pool
Elastic pools provide a cost-effective way to manage and scale multiple databases with fluctuating resource needs, ideal for multi-tenant SaaS scenarios.
B
Distractor review
Azure SQL Database (single database)
Using individual single databases for each tenant would be more expensive and less efficient because resources are allocated per database without sharing.
C
Distractor review
Azure SQL Managed Instance
Managed Instance is designed for larger databases and lift-and-shift migrations, not for managing thousands of small databases in a shared model.
D
Distractor review
SQL Server on Azure Virtual Machine
IaaS offers full control but higher management overhead and cost when hosting many small databases, and it lacks built-in elastic pooling features.
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: Azure SQL Database elastic pool — Azure SQL Database elastic pools allow multiple single databases to share a fixed set of resources, optimizing cost for workloads with many databases that have varying usage patterns. Individual single databases are more expensive per unit, and Managed Instance or SQL Server on VMs are designed for larger, more resource-intensive workloads rather than thousands of small databases.
