AIF-C01 Practice Question 44: Agent Hosting Platform

AWS Certified AI Practitioner (AIF-C01) · Test 5 · question 4 of 10

Fundamentals of GenAImedium

A company has built AI agents with an open-source framework and wants to run them in production on AWS. It needs serverless hosting with isolated user sessions, memory that persists across conversations, a way to turn its existing APIs into tools the agents can call, and tracing to debug agent behavior, all without managing infrastructure or rewriting the agents for a specific framework. Which AWS service should it use?

Show answer and explanation

Answer:

B. Amazon Bedrock AgentCore

Amazon Bedrock AgentCore is an agentic platform for building, deploying and operating agents securely at scale using any framework and foundation model, without infrastructure management. Its modular services match each requirement: Runtime is a secure, serverless runtime with true session isolation. Memory provides short-term and long-term memory that persists across sessions. Gateway converts APIs and Lambda functions into MCP-compatible tools. Observability traces and debugs agent workflows. AgentCore works with open-source frameworks such as CrewAI, LangGraph, LlamaIndex and Strands Agents (option B).

- A is wrong because JumpStart is a catalog for deploying and fine-tuning pretrained *models*. It doesn't provide agent session isolation, memory or tool gateways. - C is wrong because Knowledge Bases provide managed RAG over your documents. An agent might use one as a source of information, but it isn't a runtime for hosting and operating agents. - D is wrong because Amazon Transcribe converts speech to text. It is an AI service, not an agent platform.
