Microsoft AB-400 Explained: Exam Domains, Skills & PL-400 Changes

About this video

The Microsoft AB-400 exam introduces an updated focus on extending Power Platform solutions with code and AI. If you're preparing for the Power Platform Developer Associate certification, understanding the exam structure and the skills being assessed is an important first step. In this video, we break down the official AB-400 exam domains, the technical skills candidates should know, and the transition from the previous PL-400 exam. What you'll learn: - The four official AB-400 exam domains and their weighting percentages - How to extend Microsoft Power Platform with Dataverse, APIs, custom logic, and automation - What developers need to understand about user experience extensions and Power Apps code apps - The role of solution architecture, application lifecycle management (ALM), and system integrations - Why JavaScript, TypeScript, C#, Power Fx, REST APIs, and Microsoft Azure matter for preparation - How Microsoft Foundry and Copilot Studio fit into the updated development scope - The PL-400 to AB-400 transition dates and what existing candidates need to know How should you prepare for AB-400? Don't rely on memorizing definitions alone. Focus on understanding why a particular component, integration pattern, or development approach is appropriate for a given requirement. Review security, troubleshooting, deployment, and application lifecycle management alongside the individual technologies. A useful starting point is to classify each exam objective as demonstrated through practical experience, understood but not yet tested, or unfamiliar. This helps you prioritize hands-on practice instead of spending equal time on every topic. The goal is to build the technical judgment needed to design, develop, test, and troubleshoot Power Platform solutions—not simply recognize terminology. #AB400 #MicrosoftCertification #PowerPlatform
