Domain 1: Fundamentals of AI and ML
Question 1
A retail company wants to group their customers into segments based on purchasing behavior, but they have no predefined categories. Which ML approach is MOST appropriate?
- Supervised classification
- Supervised regression
- Unsupervised clustering
- Reinforcement learning
Show answer & explanation
Correct answer: C - Unsupervised clustering
Question 2
A company wants to predict whether a customer will churn (yes/no) based on their usage patterns. Which ML technique is MOST appropriate?
- Regression
- Classification
- Clustering
- Dimensionality reduction
Show answer & explanation
Correct answer: B - Classification
Domain 2: Fundamentals of Generative AI
Question 3
A company uses a foundation model and notices it sometimes produces outputs that contain biased stereotypes. What is the MOST likely root cause?
- The model's inference hardware is insufficient
- The model learned and reflects biases present in its pre-training data
- The temperature setting is too low
- The context window is too small
Show answer & explanation
Correct answer: B - The model learned and reflects biases present in its pre-training data
Question 4
A user asks a GenAI model about events that occurred last week, but the model provides outdated information. What is the MOST likely cause?
- The model's temperature is too high
- The model's knowledge is limited to its training data cutoff date
- The model is hallucinating
- The network connection is slow
Show answer & explanation
Correct answer: B - The model's knowledge is limited to its training data cutoff date
Domain 3: Applications of Foundation Models
Question 5
A company wants their foundation model to respond in a specific JSON format for their API integration. Which customization approach is MOST appropriate and cost-effective?
- Fine-tuning the model on JSON examples
- Continued pre-training on JSON data
- Prompt engineering with clear format instructions
- RAG with a JSON document database
Show answer & explanation
Correct answer: C - Prompt engineering with clear format instructions
Question 6
A company wants to reduce hallucinations when the FM answers questions about their products. Which customization approach is MOST effective?
- Increasing the temperature parameter
- Using RAG to ground responses in actual product documentation
- Making the model larger
- Using continued pre-training only
Show answer & explanation
Correct answer: B - Using RAG to ground responses in actual product documentation
Domain 4: Guidelines for Responsible AI
Question 7
A company fine-tunes a model and the resulting model has MORE bias than the original base model. What is the MOST likely cause?
- The fine-tuning process always increases bias
- The fine-tuning data contained biases that were introduced into or amplified by the model
- The model became too large
- The temperature was too high
Show answer & explanation
Correct answer: B - The fine-tuning data contained biases that were introduced into or amplified by the model
Question 8
A company's GenAI model passes all bias tests during development but shows biased behavior after 6 months in production. What MOST likely happened?
- The tests were wrong
- Real-world data patterns have shifted (data drift), causing the model to exhibit bias it didn't show during testing
- The model improved on its own
- AWS changed the model
Show answer & explanation
Correct answer: B - Real-world data patterns have shifted (data drift), causing the model to exhibit bias it didn't show during testing
Domain 5: Security, Compliance, and Governance for AI Solutions
Question 9
A company needs to maintain an audit trail of all data pipeline operations including data collection, transformation, and model training steps. Which is the BEST approach?
- Manual record keeping in spreadsheets
- Automated logging with CloudTrail, SageMaker Pipelines tracking, and Glue Data Catalog
- No documentation needed
- Only track the final model output
Show answer & explanation
Correct answer: B - Automated logging with CloudTrail, SageMaker Pipelines tracking, and Glue Data Catalog
Question 10
A healthcare company building an AI diagnostic tool needs to ensure end-to-end governance. Which combination is MOST comprehensive?
- Only model accuracy testing
- HIPAA compliance + data encryption + access controls + bias testing + human oversight + audit trails + model documentation
- Only cost optimization
- Only model selection
Show answer & explanation
Correct answer: B - HIPAA compliance + data encryption + access controls + bias testing + human oversight + audit trails + model documentation
