80% of ML projects don't actually need "building models from scratch." Extracting amounts from receipts, converting speech to text, filtering inappropriate images, analyzing text sentiment—these are already solved problems. Collecting data and training models for these is wasteful in time, cost, and expertise. AWS's Managed AI (pre-trained AI) Services let you solve these "already-solved problems" with a single API call. In SAP-C02 exams, this domain tests instant-recall matching: "which service fits this scenario?" more than deep theory. But traps abound—distinguishing between Macie vs Comprehend PII, or Kendra vs OpenSearch, requires precision.
