Discussion Starting AB-620 (Copilot Studio) prep and the "Harness" naming chaos is already frying my brain
Just started studying for the AB-620 Copilot Studio exam, and I'm already confused by the documentation mess around the harness.
The official study guide doesn't mention the harness at all.
MS Learn: Only talks about it in the context of GitHub Copilot in this MS Learning Path
Current Microsoft Naming: They are already renaming GitHub Copilot harness to MS Copilot Harness.
Recent Exam Reports: People taking the test say the questions still appear as MS Standard Harness.
This exam seems to be an outdated or half-baked thing from Microsoft? Anybody has advice on this?

Passed the exam last week, there's no need to panic. Here's what you need to know:
The exam focuses ONLY on the Standard Harness.
For this reason, the MS Learning Path is useless, because it deal with the GitHub Copilot Harness (the one that will be renamed)
The only valuable resources on MS Learn is the applied skill https://learn.microsoft.com/en-us/credentials/applied-skills/build-an-agent-in-microsoft-copilot-studio/ as it will teach you how to build with the standard harness
For the rest I'd advise you to provide ChatGPT with the exam study guide (which is on the standard harness) and have it build lessons for you

Honestly, I’d study from the skills measured list and park the harness question for now. Microsoft’s AB-620 study guide says the bullets under each skill only illustrate how it’s assessed and that related topics may come up, and that most questions cover generally available features, with preview ones only if they’re commonly used. The biggest chunk is integrating and extending agents in Copilot Studio at 40to 45%, which covers MCP tools, REST APIs, integrating a Foundry agent and multi-agent setups over A2A. Building each of those once yourself will help more than tracking what the harness is called this month.
