AWS Certified Data Engineer (DEA-C01) Practice Tests 2026

Preparing for the AWS Certified Data Engineer - Associate (DEA-C01) exam? This course gives you three full-length, timed practice exams with 195 exam-style questions, so you can measure your readiness, find the gaps in your knowledge and practise making the decisions the exam is built around. 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 includesThree full-length practice exams: 65 questions each, 195 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 DEA-C01 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 material is only part of passing DEA-C01.

You also need to read scenario-based questions carefully, rule out options that are possible but not the best fit, 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 domains in the official DEA-C01 exam guide:Data Ingestion and Transformation (34%): batch and streaming ingestion, transformation and pipeline orchestration.

Data Store Management (26%): choosing data stores, data cataloguing, lifecycle management and data modelling. Data Operations and Support (22%): automating data processing, analysing data, monitoring pipelines and data quality. Data Security and Governance (18%): authentication, authorisation, encryption, auditing and data privacy.

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 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.
