Study CLF-C02 Cloud Technology and Services: key concepts, common traps, and exam decision cues.
This is the biggest CLF-C02 domain because AWS wants foundational candidates to recognize the major service families and the jobs they solve. The exam is still broad rather than deep. Strong answers classify the workload first, then choose the service family that matches it.
AWS currently weights Cloud Technology and Services at 34% of scored content.
