- A
Implement RAG to retrieve relevant documents for context
RAG provides factual grounding, reducing hallucination.
- B
Provide 3 few-shot examples of conversations
Why wrong: Few-shot examples improve style but not factuality without grounding.
- C
Reduce max output tokens to 150
Why wrong: Shorter output doesn't address the source of false information.
- D
Add a system instruction: 'Only answer based on the provided context.'
This instructs the model to rely on given info, reducing hallucination.
- E
Increase temperature to 1.2
Why wrong: Higher temperature makes outputs more random, often increasing hallucinations.

Generative AI Leader Practice Question: Techniques to Improve Generative AI Model Output
This Generative AI Leader practice question tests your understanding of techniques to improve generative ai model output. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is prompt engineering a model for customer support. They want to reduce hallucination (false information) in responses. Which TWO techniques are most effective? (Choose two.)
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
✓
Implement RAG to retrieve relevant documents for context
Option A is correct because Retrieval-Augmented Generation (RAG) grounds the model's output in external, verifiable documents retrieved from a knowledge base. By providing relevant context at inference time, RAG significantly reduces the likelihood of the model fabricating information, as it can reference and paraphrase from the retrieved sources rather than relying solely on its parametric memory.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
A common mistake in this exam is to think that adjusting parameters like temperature or output tokens directly reduces hallucination, when in fact only techniques that constrain the model's knowledge source (like RAG and strict system instructions) are effective.
Trap categories for this question
Command / output trap
Shorter output doesn't address the source of false information.
Detailed technical explanation
How to think about this question
RAG works by embedding the user query, performing a vector similarity search against a document index (e.g., using FAISS or Pinecone), and prepending the top-k retrieved chunks to the prompt as context. The model then conditions its generation on this context, and techniques like 'citation grounding' can further enforce that every claim maps to a specific retrieved passage. In practice, RAG reduces hallucination rates by over 30% in customer support benchmarks, especially when combined with a system instruction that explicitly restricts the model to the provided context.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
