- A
Use Vertex AI RAG Engine
Why wrong: RAG Engine is for building custom retrieval pipelines, but Grounding is simpler for connecting to an existing data source.
- B
Enable Grounding with Google Search
Grounding allows the model to retrieve real-time information from a designated data source, ensuring responses are based on the catalog.
- C
Increase the model's temperature setting
Why wrong: Temperature affects randomness, not accuracy of factual information.
- D
Fine-tune the model with product catalog updates
Why wrong: Fine-tuning is costly and not suitable for frequently changing product data; Grounding is more flexible.

Generative AI Leader Applying Generative AI in Business Practice Question
This Generative AI Leader practice question tests your understanding of applying generative ai in business. 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 retail company has deployed a generative AI chatbot for customer support. They notice that the model sometimes provides incorrect product information. The team wants to ground the model's responses in their product catalog to improve accuracy. Which Vertex AI feature should they enable?
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
✓
Enable Grounding with Google Search
Option B is correct because Grounding with Google Search allows the model to retrieve real-time, authoritative information from the product catalog via Vertex AI's grounding service, ensuring responses are based on verified data rather than the model's internal knowledge. This feature directly addresses the need to reduce hallucinations by anchoring the model's output to a trusted source, such as a product database, without requiring custom retrieval infrastructure.
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
Cisco often tests the distinction between grounding (real-time retrieval from a trusted source) and fine-tuning (static model updates), leading candidates to mistakenly choose fine-tuning when the question emphasizes dynamic accuracy improvements.
Detailed technical explanation
How to think about this question
Grounding with Google Search in Vertex AI works by sending the user's query and the model's draft response to Google Search, which retrieves relevant snippets from indexed sources (e.g., the product catalog) and returns them as citations. The model then adjusts its output to align with these citations, effectively reducing hallucination rates by over 50% in production benchmarks. A subtle behavior is that grounding requires the catalog to be publicly accessible or indexed via a private data store, and it uses a confidence threshold to decide when to override the model's response.
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.
