Study SAP-C02 Continuous Improvement: key concepts, common traps, and exam decision cues.
This chapter is where SAP-C02 stops asking what you would build from scratch and starts asking how you would make a real AWS estate better. The exam rewards candidates who can diagnose what is weak today, then improve it with the right mix of automation, guardrails, observability, architecture change, and cost discipline.
AWS currently weights this domain at 25% of scored content.
