DP-420 Microsoft Azure Cosmos DB Developer Specialty Exams
Course Overview
About This Free Course
Prepare for the Microsoft DP-420 exam with six comprehensive practice tests containing 600 scenario-based questions focused on designing and implementing cloud-native applications with Azure Cosmos DB.
This course is designed for Azure developers, Cosmos DB developers, cloud engineers, solution architects, database professionals, and certification candidates who want to evaluate their practical knowledge before taking the exam.
The practice exams cover data modeling for Azure Cosmos DB, including embedding and referencing strategies, denormalization, logical partitions, synthetic and hierarchical partition keys, unique key policies, TTL, schema versioning, throughput models, connectivity modes, and SDK client design.
You will also practice distributed database concepts such as consistency levels, multi-region writes, automatic failover, globally distributed application design, and transactional boundaries.
Integration topics include change feed, analytical store, Microsoft Fabric integration, Spark connectivity, event-driven processing, denormalization workflows, aggregation, and downstream analytics.
Performance and optimization scenarios cover indexing policies, composite indexes, point reads, targeted partition queries, RU consumption, hot partitions, autoscale, query metrics, payload sizing, and throughput distribution.
The course also includes operational topics such as Azure Monitor, diagnostic logs, latency analysis, replication health, continuous and periodic backups, point-in-time restore, Microsoft Entra authentication, RBAC, Azure Key Vault, private endpoints, firewall rules, auditing, and disaster recovery testing.
Every question includes explanations for the correct answer and each incorrect option. These explanations help you understand why a Cosmos DB design choice is appropriate, distinguish between similar features, and identify areas that need additional study.
By completing all six practice exams, you can identify knowledge gaps, strengthen Azure Cosmos DB development skills, improve architecture and performance decisions, and build confidence through 600 professional exam-style questions.
This course is an independent exam-preparation resource and is not affiliated with, sponsored by, or endorsed by Microsoft.
