I'm looking for insights and tips on how to effectively prepare for the AB-900 exam. Does anyone have information on the main topics covered in the exam? I've heard various things, so I'm curious about a reliable focus. Also, I'd appreciate any recommendations for worthwhile resources, particularly since the exam is still new and I'm cautious about spending money on potentially outdated materials.

Check out dumpsspots.com or Udemy; their explanations tend to be detailed and helpful for understanding the concepts!
I found a few good learning paths on Microsoft's site that may be helpful:
- Explore Microsoft 365 Administration [here](https://learn.microsoft.com/training/path/explore-microsoft-365-administration)
- Explore Microsoft 365 Copilot Administration [here](https://learn.microsoft.com/training/path/explore-microsoft-365-copilot-agent-administration)
- Certification details can also be found [here](https://learn.microsoft.com/credentials/certifications/copilot-and-agent-administration-fundamentals)
Just keep up with the official links as they update resources frequently.
MSLearn is a great place to start for studying. If available for this exam, MeasureUp's practice tests are helpful too, but I heard they aren’t ready for AB-900 just yet.
I took the AB-900 just last week, and I can tell you it's way more conceptual than you might expect. Focus on high-level concepts and understanding terminology rather than memorizing technical details. Questions are often scenario-based, so reasoning through the material is key. I stuck to free materials since the official practice tests aren't out yet. I used CertBoosters, which felt aligned with what I learned. Just read questions carefully and it’ll be manageable!
The AB-900 exam is still pretty new, so it's understandable to be cautious about paid resources. It's more concept-driven rather than technical, focusing on Copilot basics, managing agents, and security. Start with Microsoft Learn—it’s in line with what you'll see on the exam—and get some hands-on practice in the admin centers if you can. This will really help you with the scenario-based questions! Honestly, if you spend a couple weeks studying consistently, you'll do fine.

Yeah, MeasureUp for AB-900 is expected to roll out by mid-April, so keep an eye out!
