Generative AI Leader Google Cloud's Generative AI Offerings Practice Question
A retailer is building a product recommendation chatbot using Vertex AI Agent Builder. They want the agent to answer questions about product availability, prices, and promotions, but also to escalate to a human agent when the query is complex. What should they configure in Agent Builder?

Correct answer & explanation
✓
Define an agent with a 'handoff to human' intent and configure the corresponding flow
In Vertex AI Agent Builder, you define intents to handle specific user requests. A 'handoff to human' intent, when triggered, initiates a configured flow that transfers the conversation to a human agent. This is the standard method for escalation. Option A is incorrect because playbooks define conversation steps but not directly the escalation trigger; they can be part of a flow but not the primary escalation mechanism. Option C is incorrect: while you could integrate a tool to call a human support API, Agent Builder provides a built-in handoff intent and flow, making custom tool integration unnecessary. Option D is incorrect: generative fallback only generates responses when the agent cannot match a query, it does not provide a structured escalation to a human.
