Questions before you buy
Is this official?
No, the AB-100 bundle is not official. Overqual is independent and is not affiliated with, sponsored by, or endorsed by Microsoft.
Does it include real exam questions?
No, the AB-100 bundle contains no exam questions, and every practice question is original.
How is the AB-100 bundle different from Microsoft's free materials?
Microsoft's free pages set out what the AB-100 exam covers. The AB-100 bundle adds a 58-page study guide that covers every exam domain, and two practice exams with 120 original questions, every answer explained. When Microsoft revises the exam, a new edition follows if the changes warrant it, included while your access lasts.
How do I get updates?
Updates to the AB-100 bundle arrive as new editions. Every bundle includes 6 months of access: download the PDFs, and any new editions, until 6 months after your purchase date. Download each new edition at overqual.com/download with the license key from your receipt email. The change log on the exam facts page says what changed.
Can I get a refund?
No. Sales of the AB-100 bundle are final, because downloaded PDFs cannot be returned. Read the free exam facts and try the 5 free sample questions first. If a download fails or you paid twice by mistake, contact Overqual to have the download fixed or the second payment refunded.
Do I need another certification before AB-100?
AB-100 can be scheduled on its own; the prerequisite applies to the certification. Microsoft's certification page says that in addition to passing AB-100 you must earn at least one of 13 Associate certifications: MB-230, MB-310, MB-330, MB-500, MB-800, MB-820, PL-400, AI-103, AI-300, AB-210, AB-250, AB-410 and AB-620 (certification page). The exam page lists two more, MB-280 and PL-200, but PL-200 retired on Aug 31, 2026 (Exam PL-200 page) and the MB-280 certification is retired (MB-280 certification page), so plan around the 13 on the certification page.
Does AB-100 replace PL-600 or MB-700?
No. Microsoft retired PL-600 (Power Platform Solution Architect) and MB-700 (Dynamics 365: Finance and Operations Apps Solution Architect) on Jun 30, 2026 and does not call AB-100 their replacement; AB-100 earns a separate Expert certification. The retirement notices link to Microsoft's AI business credentials announcement, and AB-100's prerequisite list includes PL-400 and several Dynamics 365 associate certifications (Exam PL-600 page, Exam MB-700 page, Microsoft's AB-100 study guide).
Does AB-100 include labs or case studies, and can I use Microsoft Learn during it?
AB-100's exam page does not say. Microsoft does not publish which exams contain labs, because labs can be removed at any time; the exam's introduction screen states the number of questions, case studies and labs (Microsoft exam FAQ). Microsoft's general timings are 100 minutes for associate and expert role-based exams without labs and 120 minutes for exams that may contain them, and most exams have 40-60 questions (Exam duration and exam experience). Case studies lock once you move past them. Microsoft Learn is available in a split screen during associate and expert exams, except Q&A, practice assessments and your profile, with no extra time added (Exam duration and exam experience).
Ready for AB-100?
Three PDFs, 107 pages: the study guide and two practice exams.
Which Microsoft products does AB-100 cover?
The AB-100 skills outline names products on four Microsoft platforms. The outline asks for design decisions about them: which platform hosts an agent, how it is extended, governed, tested and promoted.
