Applications of Foundation Models

Domain 3 is the largest domain. It covers practical applications of foundation models including RAG, agents, prompt engineering, Amazon Bedrock features, and selecting the right model for a task.

What You'll Be Tested On

  • Selecting the right foundation model for a use case
  • Prompt engineering: zero-shot, few-shot, chain-of-thought
  • Retrieval-Augmented Generation (RAG) and knowledge bases
  • Amazon Bedrock: model access, guardrails, agents, knowledge bases
  • Fine-tuning vs prompt engineering vs RAG — when to use each
  • Multi-modal models: text, image, code, and audio generation

Exam Tips for Domain 3

💡

Understand the trade-offs: prompt engineering (fastest, cheapest), RAG (grounded, current data), fine-tuning (specialized, expensive).

💡

Know Amazon Bedrock features: model playground, knowledge bases, guardrails, agents.

💡

RAG questions appear frequently — understand the full RAG pipeline from embedding to retrieval to generation.

💡

Practice identifying which approach (prompt engineering, RAG, or fine-tuning) fits a given scenario.
