DP-900 Practice Test Strategy

DP-900 practice is most useful when every missed question is classified. The pattern behind the miss matters more than the single correct answer.

Classify the Miss

After each missed question, label it by category: relational concept, SQL service, non-relational model, Cosmos DB, analytics workload, batch versus streaming, visualization, or general service selection. The category tells you what to review next.

Relational Mistakes

Relational misses often involve primary keys, foreign keys, joins, normalization, views, indexes, or transactional behavior. If the scenario uses structured tables and relationships, review why a relational database fits before comparing Azure SQL options.

NoSQL and Cosmos DB Mistakes

Cosmos DB misses usually come from confusing flexible document workloads with relational tables or file storage. Review document, key-value, graph, partitioning, and consistency concepts at a high level.

Analytics Mistakes

Analytics misses often involve warehouses, lakes, lakehouses, batch processing, streaming, ETL, ELT, Power BI, or Fabric. Read the scenario for whether the data is being stored, transformed, queried, visualized, or analyzed in near real time.

Service-Selection Distractors

Many wrong answers are real Azure services used in the wrong context. Azure SQL, Cosmos DB, storage, Power BI, and Fabric can all appear plausible. Choose the option that matches the workload requirement, data shape, and usage pattern.

Turn Explanations Into Review Notes

When an explanation identifies a distinction, write the distinction in your own words. Examples: SQL for relational constraints, Cosmos DB for distributed NoSQL documents, a warehouse for curated analytics, and Power BI for reports and dashboards.
