Today we organize "most frequently appearing on the surface" exam area. AWS AI/ML Services, exactly. AIF-C01 endlessly asks "which service best fits this situation?" Service name-and-use-case quick-recall ability directly means points.
Services organize in three layers: ① AI Services (APIs) used immediately, ② SageMaker for building models yourself, ③ generative AI-based Bedrock and Amazon Q. Today compress all three layers at once.
Managed services you use via API calls alone without ML knowledge. Each does "one thing well." This mapping is half the exam.
