- A
Use Retrieval-Augmented Generation (RAG) with Vertex AI Search and Gemini
RAG retrieves relevant, up-to-date medical documents from a search index, grounding Gemini's responses in trusted sources, reducing hallucination.
- B
Use Imagen to generate visual aids and combine with Gemini for text, then manually review
Why wrong: Imagen generates images, not text; manual review is not automated grounding.
- C
Fine-tune Gemini on trusted medical literature and deploy with Vertex AI Endpoints
Why wrong: Fine-tuning can help but does not guarantee factuality and requires frequent retraining to stay current; still prone to hallucination.
- D
Use only Gemini Pro with careful prompt engineering and system instructions
Why wrong: Prompt engineering reduces but does not eliminate hallucination; model may still invent facts not in its training data.
Generative AI Leader Generative AI Concepts and Technologies Practice Question
This Generative AI Leader practice question tests your understanding of generative ai concepts and technologies. 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 healthcare organization wants to use generative AI to draft patient education materials. They are concerned about the model generating incorrect medical information. Which combination of Google Cloud services should they use to ground the model's responses in trusted medical literature?
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 Retrieval-Augmented Generation (RAG) with Vertex AI Search and Gemini
Option A is correct because Retrieval-Augmented Generation (RAG) with Vertex AI Search allows the model to retrieve and cite information from a curated corpus of trusted medical literature before generating responses. This grounds the output in verified sources, reducing the risk of hallucination or incorrect medical advice, while Gemini provides the generative capabilities.
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 misconception that fine-tuning or careful prompting alone can ensure factual accuracy, when in reality RAG provides a more reliable grounding mechanism by retrieving and citing external, up-to-date sources.
Detailed technical explanation
How to think about this question
Under the hood, RAG in Vertex AI Search uses a two-stage pipeline: first, a retrieval step that embeds the user query and searches a vector database (e.g., using ScaNN or ANN algorithms) for relevant chunks from the trusted corpus; second, a generation step where Gemini receives both the query and retrieved context as input, with attention mechanisms prioritizing the retrieved text. This architecture ensures that the model's output is grounded in specific, verifiable passages, and it supports dynamic updates to the corpus without retraining. In a real-world scenario, a healthcare organization could index PubMed articles or internal clinical guidelines, and the model would cite exact document IDs and sections, enabling compliance with regulatory standards like HIPAA.
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.
