This free DOP-C02 practice test mirrors the structure and difficulty of the real AWS Certified DevOps Engineer Professional DOP-C02 exam. Every question is written against the official 2026 exam blueprint published by Amazon Web Services, ensuring you practise exactly what the exam tests — not last year's objectives.
The DOP-C02 blueprint is divided into 6weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like SDLC Automation and Configuration Management and IaC contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.

Security and Compliance
SDLC Automation
77 numbered sets, 6 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass DOP-C02 on their first attempt:
Answer before revealing
Read each DOP-C02 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which DOP-C02 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real DOP-C02 gives you roughly 2.4 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass DOP-C02 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 1,298+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 6 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing DOP-C02 on the first attempt. The most effective approach combines reading the official Amazon Web Services documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for DOP-C02 preparation:
Cover each DOP-C02 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing DOP-C02 score.
On exam day, the DOP-C02 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The DOP-C02 exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 750/1000 does not mean you need 75% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 750/1000 on the real exam.

Every question is written against the official DOP-C02 exam blueprint published by Amazon Web Services. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass DOP-C02 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The DOP-C02 covers 6 domains: Configuration Management and IaC (17%), Resilient Cloud Solutions (15%), Incident and Event Response (14%), Monitoring and Logging (15%), Security and Compliance (17%), SDLC Automation (22%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — SDLC Automation and Configuration Management and IaC — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without Amazon Web Services's authorisation. Using them violates your NDA and Amazon Web Services's certification agreement, and can result in certification revocation. Courseiva questions are original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
