These are my study notes for the AWS Certified DevOps Engineer – Professional (DOP-C02) exam — 90+ pages covering 50+ AWS services across all six exam domains, plus cheatsheets, practice scenarios, and exam strategy. I wrote them to pass the exam in December 2026; I’m sharing them so they can help you pass too.

Pick a domain below to start, or grab a cheatsheet for last-minute review.
