Answer: Agents for Amazon Bedrock

## Explanation **Agents for Amazon Bedrock** is the correct answer because: 1. **Purpose**: Agents for Amazon Bedrock are designed to perform multi-step tasks by orchestrating interactions with foundation models and external systems. 2. **API Integration**: Agents can connect to external APIs to retrieve real-time data (like live flight prices) and perform actions (like booking tickets). 3. **Task Orchestration**: They can break down complex tasks into sequential steps - first checking prices, then making bookings, handling user authentication, etc. 4. **Other options analysis**: - **Knowledge Bases for Amazon Bedrock**: Used for RAG (Retrieval Augmented Generation) to query internal knowledge bases, not for API integration. - **Guardrails for Bedrock**: Focuses on content safety and filtering inappropriate content. - **Model Customization**: Used for fine-tuning models with specific data, not for API integration. 5. **Use Case Fit**: The travel app scenario requires dynamic interaction with external flight booking systems, which is exactly what Agents for Amazon Bedrock are designed to handle.
