MD-102 Practice Test Does Not Prepare You for the Actual Exam + Poor Support Links

Well MD-102 is a role-based exam, it tests have a hands-on experience with the products (in the role of endpoint admin), as detailed in the study guide. 

By design it doesn't test your ability to read an online course or finish an assessment so using those as your only form of preparation is setting yourself up for a failure as you have just experienced. 

As a candidate for this exam, you have subject matter expertise managing devices and client applications in a Microsoft 365 tenant by using Microsoft Intune and agentic tools and workflows. 

You must have experience with Microsoft Entra ID and Microsoft 365 technologies, including Intune, as well as strong skills and experience in deploying, configuring, and maintaining Windows client and non-Windows devices. You should also have an understanding of Microsoft Security Copilot, Intune agents, and Microsoft Defender XDR.
