Generative AI Leader Fundamentals of Generative AI Practice Question
A retail company wants to build an internal assistant that answers employee HR policy questions using their existing policy documents, without exposing sensitive data to external APIs. They need a managed Google Cloud service that supports retrieval-augmented generation (RAG) and integrates with their existing data in Cloud Storage. Which Google Cloud service should they use?
⚠ Common exam trap
The trap here is assuming that any conversational AI service can ground responses in enterprise documents, when only Vertex AI Search and Conversation provides native RAG integration.

Correct answer & explanation
✓

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Document AI
Why it's wrong here
Document AI is used to parse and extract structured data from documents, such as invoices or forms. While it can process policy documents, it does not provide conversational AI or RAG capabilities. It would need to be combined with other services to build an assistant, making it not the primary service for this scenario.
- ✗
Dialogflow CX
Why it's wrong here
Dialogflow CX is a conversational AI platform for building chatbots and voice agents, but it does not natively provide RAG over enterprise documents. It focuses on intent detection and flow management, and would require custom integration with a retrieval system. It is not the best fit for grounding responses in policy documents out of the box.
- ✗
Cloud Natural Language API
Why it's wrong here
Cloud Natural Language API provides pre-trained models for sentiment analysis, entity recognition, and syntax analysis. It does not support building conversational assistants or RAG. It cannot answer HR policy questions or integrate with document repositories for retrieval, so it is unsuitable for this use case.
- ✓
Vertex AI Search and Conversation
Why this is correct
Vertex AI Search and Conversation is a managed Google Cloud service designed to build enterprise search and conversational AI applications with RAG. It ingests documents from Cloud Storage, BigQuery, and other sources, and provides grounding to reduce hallucinations, all within Google Cloud's secure environment. This matches the requirement for an internal assistant using existing policy documents without exposing data externally.
