Developer Associate

You know the AWS services. Can you choose the right behavior when a request fails, a deployment shifts traffic, or permissions cross an account boundary?

Build that decision-making practice with 344 questions for AWS Certified Developer – Associate DVA-C02. Work through development, security, deployment, and troubleshooting in focused sessions, then bring them together in two independent timed mocks.

Version matters: This course targets DVA-C02. As checked on September 28, 2026, AWS lists December 1, 2026 as the last day to take DVA-C02, with registration for DVA-C03 opening October 27, 2026. If you plan to take DVA-C03, choose preparation specifically aligned to that version. This course does not claim DVA-C03 coverage.

Practice the decisions that change the answer

• Follow message delivery and retry behavior across SQS, Lambda and event-driven integrations.
• Distinguish authorization, role trust, key policies and application tenant boundaries.
• Read deployment conditions before choosing a canary, a rollback or a reproducible test target.
• Use metrics, logs and traces to investigate a failure instead of changing settings at random.
• Check data access, conditional writes, cache correctness and the effects of eventual consistency.

Your learning path

• Development with AWS Services — 48 questions: APIs, resilient code, Lambda, messaging and data access.
• Security — 53 questions: identity, authorization, encryption and sensitive data.
• Deployment — 60 questions: artifacts, test environments, infrastructure changes and release behavior.
• Troubleshooting and Optimization — 53 questions: diagnostic evidence, observability, concurrency and caching.
• Two full-length mocks — 65 questions and 130 minutes each: mixed-domain practice with single-answer and multiple-answer questions.

The four topic-focused sets are study banks. Use short sessions, review each option's explanation, and write down the condition you missed. Save the mocks until you can explain your choices without relying on remembered wording.

Understand both the answer and the near miss

Each question includes an overall explanation, feedback for each option, and a revision prompt. The aim is to help you recognize why a tempting choice fails under the stated conditions, then apply that distinction to a different problem.

The course uses the current published C02 skill outline, including relevant AI-assisted development and testing tasks. It concentrates on the developer's use of existing AWS services and delivery workflows, rather than treating this as a broad architecture-design course.

Before you start

You should already be comfortable with basic programming, AWS APIs and common AWS services. This is a practice-test course, not a video course or a substitute for hands-on development.

The 75% practice threshold is a revision signal, not an equivalent of AWS's 720 scaled passing score. Mock domain proportions approximate the published weights; all mock questions count toward practice feedback. These are independent practice questions, not actual examination questions. BrightRung Learning is not affiliated with or endorsed by AWS, and no passing result is guaranteed.
