Every task in the exam guide

The exam guide splits each domain into task statements. Each one has a page with a short summary, the lessons that teach it and open sample questions.

Domain 1: SDLC Automation

Domain 2: Configuration Management and IaC

Domain 3: Resilient Cloud Solutions

Domain 4: Monitoring and Logging

Domain 5: Incident and Event Response

Domain 6: Security and Compliance

How these questions are made

  • Written by us from the exam guide's task statements and the AWS documentation — never from real exam content.
  • Every option carries its own explanation and a link to the AWS page that proves it.
  • A question enters a timed exam only after an independent check; until then it is a practice question.
  • Results are a plain percentage, per domain too — not an imitation of AWS's scaled score.

Questions about the DOP-C02 practice exam

Is the DOP-C02 practice exam free?
Yes. The full practice exam (75 questions, 180 minutes) is free with no sign-up, and so are the 170 practice questions, the task pages and the study path. Your attempts are saved in this browser, on this device.
How many questions does it have, and is it timed?
75 questions in 180 minutes: the same number of questions and the same time as the real DOP-C02 exam. When the time runs out, the exam is submitted as it stands, and unanswered questions count as wrong.
Are the answers explained?
After you submit, not during: like the real exam, the timed exam gives no feedback until the end. Then you get your score overall and per exam domain, and every question with each option explained and a link to the AWS documentation page behind it. In practice mode an answer is explained as soon as you check it.
What does the DevOps Engineer - Professional exam pack add?
3 more timed practice exams (Practice exam 1: 75 questions, 180 minutes; Practice exam 2: 75 questions, 180 minutes; Practice exam 3: 75 questions, 180 minutes), each scored and explained the same way, and the next version of this exam when it changes. One payment, lifetime access, no subscription. Everything above stays free. See the pack.
Can I get a refund?
Yes, with no conditions: ask within 14 days of buying and you get the whole payment back. The details are in the terms.
Is this an official AWS practice exam?
No. BytePatterns is not affiliated with, endorsed or sponsored by Amazon Web Services. Every question is written by us from the public exam guide and the AWS documentation, never from real exam content, and a score here does not predict your result on the real exam. AWS lists its own preparation resources on its certification page.
