Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply Bedrock Guardrails with contextual grounding check
RAG grounds the model in retrieved facts, while Bedrock Guardrails with contextual grounding check validates responses against sources. Both are proven techniques to reduce hallucinations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the temperature parameter to 1.0
Why it's wrong here
Higher temperature increases randomness and can worsen hallucinations.
- ✗
Use a smaller model to reduce complexity
Why it's wrong here
Smaller models may have less knowledge and can still hallucinate; model size is not a direct solution for hallucination.
- ✗
Remove all system prompts
Why it's wrong here
System prompts guide model behavior; removing them may reduce control and increase hallucinations.
- ✓
Apply Bedrock Guardrails with contextual grounding check
Why this is correct
Contextual grounding check verifies that the model's response is supported by the retrieved sources, filtering out unsupported claims.
- ✓
Use Retrieval-Augmented Generation (RAG) to retrieve relevant documents
Why this is correct
RAG provides factual context at inference time, reducing the model's reliance on internal knowledge and thus reducing hallucinations.
