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 team wants to reduce hallucinations in a question-answering model. Which THREE techniques should they consider?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fine-tune the model on a curated factual dataset
Fine-tuning on a curated factual dataset directly adjusts the model's weights to prioritize accurate, domain-specific knowledge, reducing the likelihood of generating unsupported or hallucinated content. This technique anchors the model's output in verified data, making it more reliable for question-answering tasks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 a curated factual dataset
Why this is correct
Fine-tuning on factual data improves accuracy.
Related concept
Read the scenario before looking for a memorised answer.
✓
Use retrieval-augmented generation (RAG)
Why this is correct
RAG grounds answers in retrieved documents.
Related concept
Read the scenario before looking for a memorised answer.
✓
Apply prompt engineering with specific instructions to cite sources
Why this is correct
Prompts can encourage factual responses.
Related concept
Read the scenario before looking for a memorised answer.
✗
Reduce the number of tokens in output
Why it's wrong here
Shorter answers may still be hallucinated.
✗
Increase the temperature parameter
Why it's wrong here
Higher temperature increases variability and hallucinations.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that reducing output length or increasing randomness (temperature) can improve factual accuracy, when in reality these parameters control style and creativity, not truthfulness.
Detailed technical explanation
How to think about this question
Retrieval-augmented generation (RAG) grounds the model's responses in external, up-to-date knowledge bases by retrieving relevant documents before generation, effectively constraining the output to factual sources. Prompt engineering with source-citation instructions leverages the model's instruction-following capability to enforce a verification step, often using chain-of-thought prompting to require explicit evidence before answering. In practice, combining fine-tuning with RAG creates a robust pipeline where the model's internal knowledge is corrected and externally validated.
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.
