Microsoft DP-420 Exam Topics - You’ll Be Tested in Actual Exam

When you study DP 420, think of Azure Cosmos DB work as a chain that starts with sound design and ends with steady operations. For data models, you should know how to shape items and documents around your query patterns, choose the right API behavior, and use partition keys, indexing, and unique keys to support fast reads while keeping writes efficient. You also need to understand how to model relationships, handle denormalization when it helps performance, and manage schema flexibility without losing consistency in your application logic. For data distribution, focus on selecting an effective partition key that avoids hot partitions, supports even throughput use, and scales with growth, plus knowing when to use synthetic keys and how logical partitions map to physical partitions. Integration skills include connecting apps through SDKs, handling authentication and permissions, and using features like change feed to build event driven processing and downstream updates. Optimization centers on tuning indexing policies, choosing the right consistency level for your latency and correctness needs, managing request units through query design and pagination, and using caching or materialized views when appropriate. Maintenance covers monitoring, alerts, backups and restore options, capacity planning, cost control, and safe changes like reindexing or partition strategy adjustments so the solution stays reliable as requirements evolve.
