AWS Certified Developer - Associate (DVA-C03) Practice Exams

Aligned to the official AWS Certified Developer - Associate (DVA-C03) exam guide.

Prepare to pass the AWS Certified Developer - Associate (DVA-C03) certification exam with confidence. This comprehensive practice exam course includes 700 original, exam-style questions spread across 6 full-length practice tests, carefully weighted to match the official DVA-C03 exam domains: Development with AWS Services (30%), Security (26%), Testing and Deployment (22%), and Troubleshooting and Optimization (22%).

Every question comes with a detailed explanation of why the correct answer is right and why each wrong answer is wrong. Questions are scenario-first, built around the work of a real AWS developer: writing Lambda functions, building APIs with API Gateway, modelling data in DynamoDB, wiring queues, topics and event buses, deploying with CodePipeline, CodeBuild and CodeDeploy, and debugging with CloudWatch and X-Ray.

This course covers everything new in DVA-C03: AI-assisted development with Amazon Q Developer and Kiro, integrating managed AI services such as Amazon Bedrock, the brand-new AI security task (Guardrails content filtering and prompt-injection protection, PII masking, denied topics, AgentCore session isolation, tool-use authorization and keeping sensitive content out of logs), container images and orchestration on ECR, ECS, EKS and Fargate, and AI-assisted testing, CI/CD, troubleshooting and optimization.

The real exam has 65 questions (50 scored, 15 unscored) and a passing scaled score of 720; registration for DVA-C03 opens 1 December 2026 and DVA-C02's last day is 30 November 2026 — so this is the right time to prepare for the new version. Each practice test simulates the real exam under timed conditions with an 80% passing score requirement.

A companion DVA-C03 study guide is free to read on the CertCrack website, with a chapter per exam domain, comparison tables, troubleshooting playbooks and end-of-chapter checks. Track your progress across all six tests, focus your remaining study on weaker domains, and walk into exam day fully prepared.
