1Z0-1127-25 Prompt Engineering Practice Question
A developer is using Cohere Command to answer questions grounded in internal technical manuals. They want to ensure the model only answers based on the provided documents and does not use its pre-trained knowledge. Which Cohere-specific technique should be applied?
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
✓
Use the document-grounded generation syntax by providing documents in the chat history with explicit citation instructions
Cohere's document-grounded generation syntax allows you to supply search results or documents and instruct the model to answer solely from those documents, reducing hallucination.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Fine-tune the model on the technical manuals
Why it's wrong here
Fine-tuning is expensive and not needed for grounding; document-grounded generation works at inference.
- ✗
Set temperature to 0 in the generation parameters
Why it's wrong here
Temperature controls creativity, not grounding; the model may still use internal knowledge.
- ✓
Use the document-grounded generation syntax by providing documents in the chat history with explicit citation instructions
Why this is correct
Cohere supports document-grounded generation where you supply documents and specify they are the only source.
- ✗
Use the preamble to instruct the model to answer only from the documents
Why it's wrong here
Preamble is part of system prompt but alone does not enforce document grounding without proper syntax.
