Description

Are you ready for AB-100? If you have worked through the Microsoft Learn material and still aren't sure how the exam will ask about Copilot Studio orchestration, Microsoft Foundry model choices or the ALM of agents, this course gives you a clear answer before you book.

The course contains five full practice tests of 100 questions each, 500 in total. Every question is written against the AB-100 study guide with skills measured as of October 14, 2026 (the July 22, 2026 version differs only in product naming). Each test follows the official weighting: 28 questions on planning AI-powered business solutions, 28 on design and 44 on deployment, monitoring, testing, ALM, security and governance.

If you prepared for PL-600 or MB-700, note what changed. Both exams retired on June 30, 2026, and AB-100 asks about a different world: agents built in Copilot Studio, Microsoft 365 Copilot and Microsoft Foundry, multi-agent designs, the Model Context Protocol, computer use, prebuilt Dynamics 365 and Microsoft 365 agents, model routing, evaluation and the governance of AI. Classic Power Platform or Finance and Operations architecture questions prepare you for the wrong exam.

The five AB-100 practice tests build up step by step:

  • Test 1, Groundwork: one concept per question, as a baseline.

  • Test 2, In Practice: short scenarios that separate look-alike features.

  • Test 3, Trade-offs: two answers look right and one constraint decides.

  • Test 4, Under the Hood: settings, admin paths, roles and ALM steps.

  • Test 5, Exam Day: long architect scenarios with the least time per question.

Every answer option has its own explanation, so you learn why a wrong option is wrong and what it actually does. Each question ends with a summary and a link to the official documentation, almost always Microsoft Learn, behind the answer.

After each attempt Udemy shows your score per domain, so you know where to review. The pass mark is 80% for tests 1 to 4 and 85% for test 5, higher than the real exam requires, because practising at home is easier than a proctored exam.

This is a practice-test course for AB-100. It tests and explains; it doesn't replace hands-on work in the products or the official Microsoft learning path.

Who this course is for:

  • This course is for solution architects, functional consultants and senior makers who design AI-powered business solutions with Microsoft Copilot Studio, Microsoft 365 Copilot, Microsoft Foundry and Dynamics 365, and who want to test themselves before sitting AB-100: Agentic AI Business Solutions Architect. It suits Power Platform and Dynamics 365 consultants moving into agent design, developers and IT professionals who are taking on an architect role, and technical pre-sales, project leads and AI Center of Excellence members who need to reason about ROI, governance and responsible AI. Many candidates arrive from the retired architect exams PL-600 (Power Platform Solution Architect) and MB-700 (Finance and Operations Apps Solution Architect), both retired on June 30, 2026. AB-100 is a different exam: it centres on agents, orchestration, Foundry models, prebuilt Dynamics 365 and Microsoft 365 agents, and the ALM, security and governance of AI, so PL-600 or MB-700 practice material prepares you for the wrong outline. Remember that AB-100 also requires one of the listed associate certifications. This course is a bank of 500 exam-style questions with explanations; it tests and explains, but it doesn't replace hands-on experience or the official learning path.
