What the DP-420 Exam Covers
The DP-420 validates your ability to design and build cloud-native applications using Azure Cosmos DB. You'll demonstrate expertise in database modeling, API selection, and query optimization across global-scale applications. The exam tests both theoretical knowledge and practical implementation skills based on Microsoft's official exam objectives.
Key Technical Domains You'll Master
Expect deep dives into Cosmos DB architecture, partition key strategy, and multi-region replication patterns. You'll work with SQL API, MongoDB API, and Cassandra API implementations. In practice, the exam heavily emphasizes performance tuning, consistency models, and cost optimization—real-world concerns you'll face immediately after certification.
Hands-On Lab Experience Matters
The DP-420 includes scenario-based questions requiring practical knowledge of Azure Portal, Azure CLI, and SDKs. Building actual Cosmos DB containers and writing queries during your preparation directly translates to exam confidence.
