Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure the agent to use only the knowledge base and disable internet search
Why this is correct
This ensures the agent retrieves only from provided documents.
- ✓
Set the preamble to instruct the agent to only answer based on provided context
Why this is correct
The preamble can enforce behavior to not hallucinate.
- ✗
Increase the temperature to 2.0 for more creative responses
Why it's wrong here
High temperature increases randomness, making hallucination more likely.
- ✓
Create a knowledge base that indexes the onboarding documents
Why this is correct
A knowledge base stores document embeddings for retrieval.
- ✗
Fine-tune the underlying model on the onboarding documents
Why it's wrong here
Fine-tuning is not required; RAG handles grounding without retraining.
