1. The quick verdict

Worth it if you build enterprise agents in Copilot Studio and connect them to real systems. It sits between low code and pro code: Power Platform skills plus integration work with MCP, APIs and Microsoft Foundry.

The one thing to know before you register: it is newly generally available and has no official practice assessment yet, so plan more hands-on time.

4. What the exam tests

Domain	Weight	What it means in plain language
Integrate and extend agents in Copilot Studio	40–45%	Connecting agents to enterprise knowledge, adding tools (MCP, connectors, REST APIs, computer use), and multi-agent collaboration with Foundry and Fabric.
Plan and configure agent solutions	30–35%	Planning integration, identity, channels, security and responsible AI; configuring topics, tools, knowledge and agent flows.
Test and manage agents	20–25%	Evaluating agent performance and managing releases with solutions and pipelines.

5. Who should take it, and who shouldn’t

Take it if you are:

A Power Platform or Copilot Studio developer building agents for business teams.
A consultant or ISV partner delivering Copilot Studio solutions.
An IT application developer integrating agents with enterprise systems.

Skip it or wait if you are:

A pro-code developer building on Azure with Python. AI-103 fits better.
New to Power Platform. Learn the basics first.
A business user. AB-730 is about using Copilot, not building agents.

6. What to expect after passing

What it signals: You can design, integrate, test and release enterprise agents in Copilot Studio.
What it doesn’t prove: Pro-code AI development or large-scale agent architecture.
Where it’s asked for: Microsoft partner firms and Power Platform teams; it is also one of the Associate certifications that unlock AB-100.
Natural next step: AB-100 (Agentic AI Business Solutions Architect Expert).

7. How to prepare

Official: The AB-620 study guide, Microsoft Learn modules on Copilot Studio, and the exam sandbox. A practice assessment usually appears about 8 weeks after general availability.
Practice: Use scenario questions about choosing the right integration (connector, MCP server, API or Foundry agent) under security and governance constraints.

Hands-on:

Build an agent grounded in SharePoint and Azure AI Search knowledge (Integrate and extend).
Add an MCP server or custom connector as a tool, plus a human-approval agent flow (Plan and configure, Integrate).
Create a test set, evaluate the agent, and move it between environments with a pipeline (Test and manage).

8. Compare with
