📋 Exam Strategy

Success on the AIF-C01 requires balancing foundational AI concepts with specific knowledge of AWS services. Use the following approach to structure your final preparation.


📚 Study Strategy

High-Priority Topics (Appear Most Often)

1. Generative AI Fundamentals (24%)

  • ✅ Hallucinations and how to mitigate
  • ✅ Context windows and tokens
  • ✅ Foundation models vs. LLMs
  • ✅ Transformers and attention mechanisms
  • ✅ Embeddings

2. Foundation Model Applications (28%)

  • ✅ RAG architecture and components
  • ✅ Prompt engineering techniques
  • ✅ When to use RAG vs. fine-tuning
  • ✅ Model selection criteria
  • ✅ Amazon Bedrock models and capabilities

3. ML Fundamentals (20%)

  • ✅ Supervised vs. unsupervised vs. reinforcement learning
  • ✅ Overfitting vs. underfitting
  • ✅ Precision vs. recall
  • ✅ ML lifecycle phases

4. Responsible AI (14%)

  • ✅ Bias detection and mitigation
  • ✅ Explainability importance
  • ✅ SageMaker Clarify
  • ✅ Human review with Amazon A2I

5. Security and Governance (14%)

  • ✅ Encryption at rest and in transit
  • ✅ IAM for access control
  • ✅ Model governance and versioning
  • ✅ Compliance requirements (HIPAA, GDPR)

What NOT to Over-Study

Don't Waste Time On

  • Deep math - No calculus or linear algebra required
  • Coding implementation - Conceptual understanding, not code
  • Training algorithms - Focus on use cases, not backpropagation
  • Specific pricing - Know models, not exact costs
  • Advanced ML theory - This is a practitioner exam, not data scientist

⏱️ Time Management

Exam Format

  • 120 minutes for 85 questions
  • About 1.4 minutes per question
  • Mix of multiple choice and multiple response

Strategy

First Pass (80 minutes):

  • Answer questions you know
  • Flag uncertain questions
  • Don't spend more than 2 minutes per question

Review Pass (35 minutes):

  • Revisit flagged questions
  • Eliminate wrong answers
  • Make educated guesses

Final Check (5 minutes):

  • Ensure all answered
  • Quick double-check of marked questions

No Negative Marking

Always answer every question. No penalty for wrong answers!

Key Concepts to Memorize

AI/ML Hierarchy

AI (broadest)
 └─ ML (learn from data)
     └─ DL (neural networks)

Foundation Model Providers on Bedrock

  • Anthropic: Claude (long context, reasoning)
  • Amazon: Titan (text, embeddings, images)
  • AI21 Labs: Jurassic (multilingual)
  • Cohere: Command (text generation)
  • Meta: Llama 2 (open-source)
  • Stability AI: Stable Diffusion (images)

RAG Components

  1. Document ingestion and chunking
  2. Embedding generation
  3. Vector database storage
  4. Semantic search/retrieval
  5. Context-augmented generation

Responsible AI Pillars

  • Fairness
  • Explainability
  • Privacy
  • Safety
  • Security
  • Transparency


🧠 Memory Aids

Remember Generative AI Limitations (HCBCT)

  • Hallucinations
  • Context window limits
  • Bias in training data
  • Cost (computational)
  • Training cutoff date

Remember ML Lifecycle (BDFTEDM)

  • Business problem
  • Data collection
  • Feature engineering
  • Training
  • Evaluation
  • Deployment
  • Monitoring

Remember Prompt Engineering Types (ZFC)

  • Zero-shot (no examples)
  • Few-shot (with examples)
  • Chain-of-thought (show reasoning)
