How to use this handbook
Scenario-first notes for SAP-C02. Each page is a decision, not a data sheet.
SAP-C02 rarely asks "what is X?". Almost every question describes a company, lists its constraints, and asks for the option that fits them best. So these notes are built around decisions: which option wins under which constraint, and which option looks right but isn't.
Reading a page
Each page follows the same shape:
The decision. One line on the question this topic answers.
The picture. A diagram or comparison table that shows the moving parts.
Signals and traps. The wording that points to an answer, and the tempting options that are wrong.
Scenarios. Short exam-style questions you can answer on the page. Your answer is checked right away.
The callouts
Exam signal
A keyword or constraint that usually decides the answer.
Trap
A common wrong answer, and why it's wrong.
Legacy: use the newer service instead
Something older study guides still teach that AWS has retired or replaced.
Traps list common wrong answers. They're worth reading even when the correct answer seems obvious.
Structure
Sections follow the four domains of the official SAP-C02 exam guide, and each page lists the exam tasks it covers. Start with the exam itself.
