DP-900 Exam Structure and Domain Weightings
The DP-900 exam is a 60-minute test consisting of 40-60 questions, requiring a passing score of 700. The exam covers four core domains, which should guide your study schedule:
- Describe core data concepts (15-20%): Covers batch and streaming data, relational structures, and analytical techniques.
- Describe how to work with relational data on Azure (25-30%): Covers Azure SQL Database, managed instances, and open-source database engines.
- Describe how to work with non-relational data on Azure (25-30%): Covers Cosmos DB, Blob Storage, Table Storage, and File Storage.
- Describe an analytics workload on Azure (25-30%): Covers Data Factory, Synapse Analytics, HDInsight, and Power BI.
8 Steps to Prepare and Crack the DP-900 Certification
1. Master Relational Data Concepts and Workloads
Begin by mastering relational database concepts. Understand tables, rows, columns, schemas, indexes, and views. Learn to differentiate between transactional processing systems (OLTP) and analytical processing systems (OLAP). Focus on the core characteristics of relational workloads, including ACID properties (Atomicity, Consistency, Isolation, Durability), and how SQL queries retrieve structured information:
-- Example SELECT statement in SQL to retrieve aggregate sales metrics
SELECT ProductID, COUNT(OrderID) AS TotalOrders, SUM(Quantity) AS TotalQty
FROM SalesOrderDetails
GROUP BY ProductID
HAVING SUM(Quantity) > 100
ORDER BY TotalQty DESC;2. Understand Non-Relational Data Concepts and Formats
Non-relational data, often called NoSQL, is designed for unstructured and semi-structured datasets. You must learn the four primary non-relational data formats: key-value stores, document databases (like JSON), wide-column stores, and graph databases. Focus on scenarios where non-relational storage is preferred over relational systems, such as handling rapid changes in database schemas or processing massive amounts of unstructured data.
3. Learn Azure SQL Database and Managed Instances
Microsoft offers multiple relational database solutions in Azure. You must understand the difference between Azure SQL Database (a fully managed PaaS database), Azure SQL Managed Instance (offering near 100% compatibility with on-premises SQL Server instances), and SQL Server running on Azure Virtual Machines (an IaaS model where you retain full control over the OS). Also, study Azure's open-source database offerings, including Azure Database for MySQL and Azure Database for PostgreSQL.
4. Explore Azure Cosmos DB APIs and NoSQL Models
Azure Cosmos DB is Microsoft's globally distributed NoSQL database. A key exam topic is Cosmos DB's multi-model API structure. You must learn which API to use based on your data structure: SQL API (document data), MongoDB API (document data), Cassandra API (column-family), Gremlin API (graph data), and Table API (key-value data). Study the benefits of Cosmos DB, including single-digit millisecond response times and global scale.
5. Understand Analytical Workloads and Data Warehousing
Analytical workloads involve examining large volumes of historical data to uncover trends and patterns. You must understand the architecture of modern data warehousing. Study Azure Synapse Analytics, a cloud service that combines enterprise data warehousing and Big Data analytics, allowing you to run SQL queries against massive datasets at scale.
6. Deep Dive into Azure Data Factory and ETL Pipelines
Data integration is crucial for analytical systems. Azure Data Factory is a managed cloud service designed for Extract, Transform, and Load (ETL) and Extract, Load, and Transform (ELT) processes. Learn how to design pipelines that copy, clean, and transform data from diverse sources, making it ready for downstream analytics.
7. Master Data Visualization with Microsoft Power BI
Analytical insights are only useful if they can be communicated clearly. Microsoft Power BI is the business intelligence tool used to design interactive dashboards. You must understand how Power BI connects to data sources (including Azure SQL Database and Synapse), how to design datasets, and the role of reports and dashboards in data storytelling.
8. Practice with Official Microsoft Learning Paths and Mock Exams
Once you have studied the material, test your knowledge. Complete the official DP-900 learning paths available on the Microsoft Learn Portal. Use Dev Knowledge's TestPrep platform to attempt practice exams, analyze your performance, and identify areas that need review before scheduled exam day.

❓ Frequently Asked Questions (FAQ)
Are there database programming questions on the DP-900 exam?
No. As a fundamentals exam, you will not be asked to write complex SQL scripts or build database schemas. You only need a conceptual understanding of basic SQL syntax (such as SELECT statements) and data formats like JSON.
Is there any negative marking in the DP-900 exam?
No. Microsoft certification exams do not have negative marking. If you are unsure of an answer, eliminate obviously incorrect options and choose your best remaining answer. Ensure you attempt every question.
What is the difference between batch processing and stream processing?
Batch processing collects data over a period and processes it in large blocks (e.g., generating end-of-day sales reports). Stream processing analyzes data in real-time as it is generated (e.g., monitoring credit card transactions for fraud detection).
