[EN] AWS DVA-C02 Developer Associate Practice Exams 2026

Prepare for the AWS Certified Developer - Associate (DVA-C02) exam with 570 questions organized into 3 full practice tests. This English course uses practical scenarios to help you read requirements carefully, compare plausible options, and make technically sound decisions when developing, securing, deploying, and troubleshooting applications on AWS. Every question includes an explanation for each answer option, so you can learn why the correct choice fits and why each distractor does not.

What you will practice

- Making design decisions with AWS SDKs and APIs

- Designing AWS Lambda solutions and event-driven processing

- Choosing among DynamoDB, SQS, SNS, and Kinesis

- Integrating IAM and encryption into application development

- Comparing CI/CD workflows and deployment strategies

- Using monitoring data to troubleshoot performance issues

Coverage follows the current DVA-C02 domains: Development with AWS Services, Security, Deployment, and Troubleshooting and Optimization. The questions focus on applying AWS services to application development, deployment, and troubleshooting rather than memorizing isolated facts. Explanations compare related services, features, commands, and design patterns so that you can understand the technical reason behind each decision.

Course structure

Each of the 3 practice tests contains 190 questions, for 570 questions in total. Questions are randomized, the passing score is 70%, and each test allows up to 240 minutes. The domain label on each question helps you review your results and identify weak areas after an attempt.

Recommended study method

Take a practice test under timed conditions before reviewing the explanations. Revisit every incorrect answer and any question you answered without confidence. Compare the explanations for all options, consult the relevant official AWS documentation, and then retake the areas that need more work after a few days. Confirm that you can explain the reasoning in your own words instead of memorizing an answer.

Who this course is for

This course is intended for candidates preparing for AWS Certified Developer - Associate, learners who want to test knowledge gained from official documentation or video training, professionals who want practice with scenario-based technical decisions, and test takers who want to identify and revisit weak exam domains. Intermediate familiarity with core AWS services and basic application development, deployment, and troubleshooting terminology is recommended.

Quality and currency

The source questions and explanations were checked for structure, duplicates, answer consistency, technical quality, and alignment with the current DVA-C02 domains. Questions without a uniquely supportable answer, or whose outcome depended on an obsolete exam version, were excluded. AWS services, product behavior, and certification scope can change, so review the latest official exam guide and relevant official AWS documentation before your exam.
