AIF-C01 Fundamentals of Generative AI Practice Question
Which TWO AWS services can be used to build a chatbot that responds to customer inquiries using a company's documentation as source? (Select two.)
⚠ Common exam trap
AWS often tests the distinction between services that provide conversational interfaces (like Lex) versus those that enable retrieval-augmented generation from custom data sources (like Bedrock with RAG or Q Business), leading candidates to mistakenly select Lex because it is a chatbot service, even though it lacks native document retrieval capabilities.

Correct answer & explanation
✓
Amazon Bedrock with RAG
Amazon Bedrock with RAG (Retrieval-Augmented Generation) enables a chatbot to retrieve relevant chunks from a company's documentation and use them as context for a foundation model to generate accurate, grounded responses. This approach directly addresses the need to answer customer inquiries using proprietary or domain-specific source material.
