Graded Quiz: Build a Generative AI Application with LangChain :Develop Generative AI Applications: Get Started (BM RAG and Agentic AI Professional Certificate) Answers 2025
Question 1
Nina’s first step when selecting an AI model:
❌ Deploy the model
✅ Write a clear definition of the use case and requirements
❌ Select cheapest
❌ Choose highest-rated
Explanation:
A clear use case ensures the model selection aligns with actual business needs.
Question 2
Priya wants the model to continue performing well. What should she do?
✅ Continuously test and update the model as needed
❌ Skip monitoring
❌ Rely on initial tests
❌ Avoid switching models
Explanation:
Continuous evaluation ensures the model adapts to changing needs and data.
Question 3
Why compare different AI models using the same prompt?
❌ Eliminates guardrails
❌ Ensures faster integration
❌ Reduces deployment complexity
✅ Allows consistent evaluation across models
Explanation:
Using the same prompt provides a fair comparison of performance and output quality.
Question 4
What should Leila analyze when comparing AI models?
❌ API update frequency
✅ Performance, speed, reliability, cost
❌ Popularity
❌ Training dataset size
Explanation:
These four metrics determine real-world suitability of the model.
Question 5
How can Tania improve domain-specific performance?
✅ Fine-tune the model with domain-specific data
❌ Zero-shot prompting
❌ Prompt chaining
❌ Random prompting
Explanation:
Fine-tuning adapts the model to specialized terminology and tasks.
Question 6
Devon must keep sensitive data inside company infrastructure. Best approach?
❌ External datasets
❌ APIs
❌ Public cloud
✅ Run the AI model locally
Explanation:
Local or on-prem deployment ensures data never leaves company boundaries.
Question 7
Which method gives the model examples to follow?
❌ Chain-of-thought
❌ Zero-shot
❌ Random prompting
✅ Few-shot prompting
Explanation:
Few-shot prompting includes sample inputs/outputs to guide model behavior.
