In this lesson
Prepare for the AI-500 exam (Microsoft Certified: Multi-Agent AI Solutions Expert). In this lesson: integrating existing agents with A2A (agent cards, the A2A tool, incoming A2A, the Foundry Control Plane) or MCP, Microsoft Agent Framework, LangChain, and LangGraph with the langchain-azure-ai package, why framework choice is tactical, Hugging Face Transformers for specialized models, and middleware for logging, authorization, and exception handling. Includes three original practice questions.
Preview the topics
- The acquired visa agent runs on LangGraph in another cloud and already speaks A2A. Contoso’s trip planner in Foundry must call it with authentication and monitoring, without a rewrite. What should the team do?
- Contoso must tag names, dates, and document numbers in millions of passport texts, cheaply and inside its private network. What fits?
- Every Contoso agent repeats the same code to log tool calls, check permissions, and catch tool errors, and the copies have drifted apart. What should the team build?
