AWS Certified Developer (DVA-C03) Practice Tests 2026

Preparing for the AWS Certified Developer - Associate (DVA-C03) exam? This course gives you two full-length, timed practice exams with 130 exam-style questions, written for the new C03 version of the exam, so you can measure your readiness, find the gaps in your knowledge and practise the development decisions the exam is built around.DVA-C03 replaces DVA-C02, and the questions reflect the updated exam guide, including newer topics such as building generative AI features with Amazon Bedrock, securing AI-enabled applications and modern observability with OpenTelemetry and Amazon CloudWatch. Outdated approaches that no longer fit the exam have been removed.Every question includes an explanation for each answer option, so you learn why the correct answer is right and why each of the other options does not fit the scenario. Use the practice exams to check your understanding before exam day, not to memorise answers.What this course includesTwo full-length practice exams: 65 questions each, 130 questions in total, each with a 130-minute time limit.Two question formats: multiple-choice (one correct answer) and multiple-response (two or more correct answers), with the number to select stated in the question.Every option explained: each answer option carries its own explanation, plus an overall explanation of the correct answer.Links for further study: overall explanations point you to relevant AWS documentation so you can go deeper on any topic you miss.Domain tagging: every question is mapped to an official DVA-C03 domain, so your results show where you are strong and where you need more work.Practice on any device: take the exams on desktop or mobile, as often as you like.Why practise with timed exams?Knowing the services is only part of passing DVA-C03. You also need to read code-focused scenarios carefully, spot the detail that rules out a plausible option, and keep your pace across the full sitting. Working through a complete timed exam builds that judgement and stamina, and the explanations turn every mistake into a lesson you can use.Exam domains coveredThe questions are spread across the four domains in the official DVA-C03 exam guide:Development with AWS Services (30%): writing application code for AWS, building with Lambda, APIs, messaging and data stores, and integrating AI services into applications.Security (26%): authentication and authorisation, encryption, secrets management and securing application data and AI workloads.Testing and Deployment (22%): preparing artefacts, testing in development environments, automating deployment and deploying code with CI/CD.Troubleshooting and Optimization (22%): root cause analysis, instrumenting code for observability and optimising applications on AWS.How to use the practice examsTake your first attempt under exam conditions: set aside the full time, avoid notes and answer every question to get an honest baseline.Review every explanation: read the explanation for each option, including questions you answered correctly, to confirm your reasoning.Find your weak domains: use the domain results to see which areas cost you the most marks.Study the gaps: revisit the official DVA-C03 exam guide and the linked AWS documentation for those domains.Retake until you score 100%: retake the practice exams until you score 100% on all of them on your own and can explain why each answer is right, not just which option it is.Who this course is forCandidates preparing for the AWS Certified Developer - Associate (DVA-C03) examSoftware developers who build, deploy and debug applications on AWSDevelopers who studied for DVA-C02 and want practice aligned to the new C03 exam guideDevOps and cloud engineers who want to validate their AWS development knowledgeCandidates who have finished their DVA-C03 study and want a timed readiness checkAbout your instructorYour instructor is a certified SAFe SPC and enterprise consultant who works with SAFe, Scrum and wider Agile frameworks at practitioner and coaching level, including on large-scale transformation programmes, and builds structured certification practice courses that focus on clear, option-by-option explanations.Important informationThis is an independent practice-test course.
