Designing and Building Integrated AI Agent Solutions in Copilot Studio Study Guide

If you are getting ready for AB-620, you are in the right place. This is the written companion to our practice exams: a complete walk through everything Designing and Building Integrated AI Agent Solutions in Copilot Studio tests, gathered in one place.

AB-620 is a judgment exam far more than a recall one. Most questions hand you a working scenario and two options that both technically produce the right output, then ask which one a careful builder would ship. Does this system attach as a knowledge source, a tool, or a connected agent? Does the call run with end user credentials or with maker-provided credentials? The exam consistently rewards the narrower, more explicit configuration, the one whose scope stops it firing anywhere else, and it expects you to know that a rule written into agent instructions is not a rule that holds at runtime.

The guide follows the official domains and weights them the way the real exam weights them, so integrating and extending agents gets the most room and testing and release management the least. Each chapter builds the mental model in plain language first, then separates the look-alike options with a comparison table and a decision tree, and closes with a cheat sheet of the sharp facts worth one last read. Start at the top, or pick a domain from the list beside this page.
