The AWS Developer Associate exam in 2026 is still the DVA-C02 version. AWS lists the exam as 65 questions, 130 minutes, multiple-choice or multiple-response format, and a 150 USD exam fee. The exam validates skills for developing, testing, deploying, and debugging cloud-based applications on AWS.

What Has Changed in the Exam Focus?

The biggest change is not a new exam code in 2026. The real change is the stronger focus on modern AWS development work. Candidates now need better understanding of serverless apps, secure access, monitoring, deployment pipelines, and service integration.

The official DVA-C02 exam guide lists four major domains:

AWS’s official guide confirms these domains and weightings.

Development With AWS Services Is Still the Biggest Area

The largest domain is Development with AWS Services at 32%. This means candidates should understand how applications use AWS services through SDKs, APIs, and event-driven patterns.

Study Lambda, API Gateway, DynamoDB, S3, Step Functions, EventBridge, SQS, SNS, and application integration. You should know when to use each service and how they connect in real application workflows.

Security Has Become More Important

Security carries 26% of the exam, so it is not a small section. Candidates should study IAM roles, policies, least privilege, encryption, secrets, KMS, Cognito basics, and secure access patterns.

In 2026, AWS developers are expected to understand security inside the development process. It is not only the cloud architect’s responsibility.

Deployment and CI/CD Matter More

The Deployment domain is 24%, which makes it another major exam area. Candidates should understand CodePipeline, CodeBuild, CodeDeploy, CloudFormation, SAM, Elastic Beanstalk, containers, and deployment strategies.

The exam may test how to package, deploy, update, roll back, and automate applications using AWS services.

Troubleshooting and Optimization Are Tested Practically

Troubleshooting and Optimization makes up 18% of the exam. This domain tests whether you can monitor applications, read logs, use CloudWatch, debug failures, improve performance, and choose efficient solutions.

This section rewards hands-on practice. Reading theory alone may not be enough.

What You Should Study in 2026

Focus on:

• Lambda, API Gateway, DynamoDB, S3
• IAM, KMS, Secrets Manager, Cognito
• CloudWatch logs, metrics, alarms, and X-Ray
• SQS, SNS, EventBridge, Step Functions
• CI/CD tools and deployment models
• AWS SDKs and CLI usage
• Serverless app design
• Error handling and retries
• Cost and performance optimization

AWS also provides official practice question sets through Skill Builder, which can help candidates understand exam-style questions.
