Free DP-900 practice exams give you a quick way to check your readiness for the Microsoft Azure Data Fundamentals certification. Whether you are starting your data career, moving from on-premises databases to Azure, or shoring up the prerequisites for DP-203 or DP-300, working through realistic mock questions is the surest way to see which Azure data services you actually understand and which you only recognise.
What DP-900 covers
The DP-900 exam validates skills across four official domains. You describe core data concepts including structured, semi-structured, and unstructured data, transactional versus analytical workloads, and common roles like data engineer, data analyst, and database administrator. You identify considerations for relational data on Azure across Azure SQL Database, SQL Managed Instance, SQL Server on Azure VM, Azure Database for PostgreSQL, and Azure Database for MySQL. You describe considerations for non-relational data using Azure Cosmos DB APIs, Azure Table Storage, and Azure Blob Storage. You describe analytics workloads built on Azure Synapse Analytics, Azure Databricks, Azure Stream Analytics, Microsoft Fabric, and Power BI. The exam is 45 minutes with roughly 40 to 60 questions and a 700/1000 passing score.
What's in these practice exams
Our free Azure Data Fundamentals practice questions cover all four exam domains weighted to match the real exam:
- Structured, semi-structured, and unstructured data, OLTP versus OLAP, batch versus stream, ETL versus ELT
- Azure SQL Database tiers, SQL Managed Instance use cases, vCore versus DTU pricing, and elastic pools
- Cosmos DB APIs (NoSQL, MongoDB, Cassandra, Gremlin, Table), consistency levels, partition keys, and RUs
- Blob Storage tiers, redundancy options (LRS, ZRS, GRS), Azure Data Lake Storage Gen2, and Azure Files
- Modern data warehouse patterns in Synapse, Microsoft Fabric, OneLake, Delta Lake, and the medallion architecture
- Power BI Desktop, the Power BI service, datasets, dashboards, paginated reports, and DAX
The first set is completely free with no signup. The remaining 24 sets unlock premium features like score tracking, weak-area analytics, and timed mode that simulates the real exam.
How to use these effectively
Start with the free set to spot weak domains. Read every explanation, not just the ones you missed, because the rationales call out the service-to-scenario mapping that the exam loves to test. Once you have studied your weaker areas, mix sets across domains rather than burning through one topic at a time, because the real test jumps between relational, non-relational, and analytics in a single sitting. Aim to score 85% or higher across multiple sets before booking the real exam, since the question count is small and a few mistakes go a long way at the fundamentals level.
