Exam Overview & Scope
The DP-420 covers designing distributed database solutions, optimizing throughput and consistency models, and implementing multi-region replication strategies. You'll face 40-60 questions testing hands-on Azure Cosmos DB deployment scenarios. The exam requires practical understanding of partition key design and cost optimization techniques used in production environments.
Core Competencies Tested
Microsoft focuses on three key areas: data modeling for cloud-native apps, implementing security and compliance controls, and automating deployment with Azure resource templates. You must demonstrate expertise in choosing appropriate consistency levels (strong, bounded staleness, eventual) for specific business requirements. Hands-on lab scenarios dominate the exam format.
Key Topics to Master
Study container design, indexing policies, stored procedures, and change feed implementation. Cosmos DB API selection—SQL, MongoDB, Cassandra, Gremlin—is critical since each serves different application architectures. Practice provisioning throughput models and designing partition strategies for handling variable workloads at scale.
