AWS Certified Developer - Associate (DVA-C02) practice exam & study guide

AWS positions the Developer - Associate as proof that you can build, deploy, and maintain applications on AWS. The exam leans on serverless and application services — Lambda, DynamoDB, API Gateway, SQS/SNS, Cognito, KMS — and expects you to reason about how they fit together in code rather than how to click through the console.

AWS suggests around one year of hands-on experience developing applications with AWS services before attempting it. Focused study on the core developer services and their SDK patterns, plus practice on scenario questions, is what the exam actually rewards.

DVA-C02 is a clear step up from the Cloud Practitioner and, like the other associate exams, is scenario-based. Questions rarely have a single obvious answer — several options are technically valid and you must pick the one that best fits the stated requirement, whether that is resilience, security, or cost.

The difficulty comes from needing genuine developer familiarity: you are expected to know how services behave in code (for example, how a Lambda event source mapping polls SQS, or when to use a DynamoDB secondary index). The most effective preparation is heavy practice on scenario questions until those service behaviours are second nature.

The live DVA-C02 exam contains 65 questions to be answered in 130 minutes, delivered as multiple-choice (one correct answer) and multiple-response (two or more correct answers) items. A subset are unscored questions AWS uses to trial future content, but you cannot tell which, so answer every question with equal care.

You can sit the exam at a Pearson VUE test centre or through online proctoring from home. Our full-length practice mock mirrors this format with a 65-question, 130-minute timer so you can rehearse pacing — about two minutes per question — before test day.

AWS scores DVA-C02 on a scaled range of 100 to 1,000, and you need 720 to pass. The score is scaled rather than a simple percentage because question difficulty varies, and AWS does not publish per-domain pass marks — you need an overall 720, so a weaker domain can be offset by a stronger one. Our practice mock flags a pass at 72% to give you a comparable target.

The DVA-C02 exam costs 150 USD (prices vary slightly by region and currency), and the certification is valid for three years before it needs recertification. Everything on this hub — questions, mock exams, glossary, and domain guides — is completely free, so you can prepare thoroughly before paying to sit the exam.

The Developer - Associate is aimed at people in a software-development role who build applications that run on AWS. AWS recommends around a year of hands-on experience developing with AWS services, though it is also a common goal for developers formalising cloud skills they already use.

It is a natural next step from the Cloud Practitioner for those heading into engineering, and it pairs well with the Solutions Architect - Associate for a broader view of building on AWS.

The certification is relevant to roles such as cloud developer, software engineer, and backend or serverless developer, where building applications on AWS is part of the job.

How much any certification moves compensation depends heavily on geography, seniority, and hands-on experience, so treat any single salary figure with caution. DVA-C02 is best viewed as a way to demonstrate cloud-development knowledge rather than a guaranteed raise on its own.

Candidates with solid AWS development experience often need four to eight weeks; those newer to AWS should plan for two to three months at roughly an hour a day. The most efficient path is to learn the core developer services domain by domain, then shift the majority of your time to timed scenario practice so you get used to how AWS frames trade-off questions.

A proven rhythm is to study one domain at a time and drill its topic quiz immediately, then move to mixed, full-length timed mocks in the final stretch — reviewing every explanation, including for questions you answered correctly, because DVA-C02 distractors are built from plausible but sub-optimal implementations. Use the per-domain results here to find your weakest area and drill it again before booking your seat.

Start by reading each domain above so you know where the marks are, then work the practice questions domain by domain. Every question on MockAPI reveals a full explanation and tells you why each wrong answer is wrong — that second part is where most of the learning happens on a scenario-based exam built from close alternatives.

When you can answer topic drills comfortably, move to a full-length timed mock to rehearse pacing and stamina, and use the glossary to close any gaps in terminology. Aim to score consistently above the pass mark on mocks before you book the real thing.

Yes. You can sit DVA-C02 either at a Pearson VUE testing centre or online from home with OnVUE remote proctoring. For the online option you need a quiet, private room, a stable internet connection, a webcam, and government-issued photo ID; a proctor monitors the session, and you will be asked to show your surroundings before you begin.

If you do not pass, AWS lets you retake the exam after a 14-day waiting period, with no limit on attempts, though each attempt requires a new paid registration. Results are typically available within a few business days in your AWS Certification account, where you can also download your certificate and digital badge once you pass.

The Developer - Associate pairs naturally with the other associate exams — Solutions Architect - Associate (SAA-C03) and SysOps Administrator - Associate — to round out your view of building and running workloads on AWS.

From the associate tier you can progress to the professional certifications, such as the DevOps Engineer - Professional (which builds directly on developer and operations skills), or branch into specialty credentials. Pairing any of these with real hands-on project experience is what turns a certificate into a career.
