Practice what matters. Pass with confidence.

A five-step plan to pass DVA-C02

Find your gaps

Take the free diagnostic. It scores you by domain so you know exactly what to study, before you spend evenings or a cent on the exam.

Practice what matters

Work the objectives where practice will move your score most, not the ones you already know. Original questions with explanations that teach.

Take mock exams

Test under realistic time and question constraints. Mocks surface pacing problems and weak domains a study guide can't.

Do a final review

Tighten your single weakest domain and re-check the never-miss objectives.

Schedule when the evidence says so

Use your readiness score and domain results to decide. Walk in prepared, not hopeful.

DVA-C02 exam objectives

The published blueprint, with domain weights. Practice weighted the way the exam is weighted.

Development with AWS Services

32%

Develop code for applications hosted on AWS (event-driven, microservices, and fanout patterns; create/maintain APIs; call AWS services with SDKs; messaging services and Amazon EventBridge)
Develop code for AWS Lambda (configure memory/concurrency/timeout/runtime/handler/layers/triggers/destinations, access private VPC resources, handle event lifecycle and errors with DLQs, tune performance)
Use data stores in application development (DynamoDB keys and indexing, query vs. scan and consistency models, data lifecycles, and caching services)

Security

26%

Implement authentication and authorization (federated access with Amazon Cognito and IAM, bearer tokens, assume IAM roles, define permissions for IAM principals, fine-grained authorization)
Implement encryption using AWS services (encryption at rest and in transit, client-side vs. server-side, use AWS KMS keys to encrypt/decrypt, key rotation)
Manage sensitive data in application code (encrypt environment variables, secret management services, classify and sanitize PII/PHI, application-level data masking)

Deployment

24%

Prepare application artifacts and test in dev environments (manage dependencies and container images, code repositories, dev endpoints and API Gateway stages, deploy AWS SAM template updates)
Automate deployment testing and implement IaC (Lambda/API Gateway test events, deploy AWS SAM and CloudFormation templates, Lambda aliases and container image tags for integration testing)
Deploy code using AWS CI/CD services (commit to invoke build/test/deploy actions, orchestrated pipelines, rollbacks, blue/green, canary, and rolling deployment strategies)

Troubleshooting and Optimization

18%

Assist in a root cause analysis (debug code, interpret and query metrics/logs/traces, custom CloudWatch metrics with EMF, troubleshoot deployment failures using service logs)
Instrument code for observability (effective and structured logging, emit custom metrics, add tracing annotations with AWS X-Ray, notification alerts and health checks)
Optimize applications (define concurrency, profile performance, determine minimum memory/compute, application-level caching, analyze logs for bottlenecks)

Common questions

What does the DVA-C02 exam cover?

AWS Certified Developer - Associate covers 4 domains: Development with AWS Services, Security, Deployment, Troubleshooting and Optimization. Each is weighted, so your practice should be weighted the same way.

How do I know when I'm ready for DVA-C02?

Use an evidence-based readiness score (knowledge, blueprint coverage, consistency, and recency), not a completion percentage. When it says you're prepared, you are.

Are these practice questions exam dumps?

No. Every question is original and mapped to the published objectives. We never use dumps or leaked material.
