I sat for the AB-620 exam two weeks ago. The exam covers planning and configuring agent solutions, integrating and extending agents in Copilot Studio, and testing and managing agents. I started with the official Microsoft study guide but needed something faster that let me practice real questions. I discovered ITExamsTopics while searching online for AB-620 practice questions. After trying their free demo, I found the exam-style format useful, so I decided to use their desktop version for my preparation.

What helped most was how the exam-style questions were framed on their platform - they showed how the real exam tests your understanding instead of just memorization. Since integrating and extending agents makes up 40-45% of the test, I focused heavily on those practice questions first through their desktop tool covering connectors REST APIs MCP and multi-agent solutions. Then I worked through planning and configuring agent solutions at 30-35% and testing and managing agents at 20-25%. I went through multiple rounds of real exam questions and sample questions before my exam date. If you're prepping for AB-620, try their free demo first, then grab ITExamsTopics desktop version for actual exam questions.
