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 wants to build a customer support chatbot that answers based on internal documentation. They use Vertex AI Search and want to ensure the model only uses retrieved documents. What should they do?
Fine-tune the model on the documentation
Why wrong: Fine-tuning memorizes data but the model may still generate outside retrieved context.
Enable grounding with Vertex AI Search
Ground forces the model to answer based on provided context.
Increase max output tokens
Why wrong: Controls length, not retrieval adherence.
Set temperature to 0.0
Why wrong: Reduces randomness but does not anchor the model to retrieved documents.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable grounding with Vertex AI Search
Grounding with Vertex AI Search restricts the model to the retrieved context, preventing it from using internal knowledge. Setting temperature to 0.0 reduces creativity but doesn't enforce retrieval. Fine-tuning is unnecessary, and increasing max tokens doesn't affect retrieval.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Fine-tune the model on the documentation
Why it's wrong here
Fine-tuning memorizes data but the model may still generate outside retrieved context.
Enable grounding with Vertex AI Search
Why this is correct
Ground forces the model to answer based on provided context.

Set temperature to 0.0
Why it's wrong here
Reduces randomness but does not anchor the model to retrieved documents.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
