The exam this app prepares you for is new, and most study material on the store is for the exam it replaced. Microsoft retired AI-102, Azure AI Engineer Associate, on 30 June 2026. Its successor is AI-103, Developing AI Apps and Agents on Azure, built around agents, multi-agent orchestration and Microsoft Foundry rather than the older service-by-service approach. This bank was written against the skills measured as of 16 April 2026. 250 QUESTIONS, EVERY OPTION EXPLAINED Each question explains why the right answer is right and why each wrong answer is wrong - 1,019 written explanations in total. On an exam where several options look plausible, understanding why the near-miss fails is most of the skill. WHAT THE NEW EXAM ACTUALLY TESTS Building agents: roles, goals, tool schemas, conversation memory, function calling Multi-agent orchestration, termination conditions and approval flows Choosing Foundry services and models per task, including small language models Retrieval Augmented Generation, grounding, and evaluating groundedness Model reflection, self-critique loops and chain-of-thought evaluation Observability: tracing, token analytics, safety signals, latency breakdowns Responsible AI for agents: tool-access control, oversight modes, audit trails Indirect prompt injection, including instructions embedded in images Content Understanding for documents, images, audio and video Computer vision: image and video generation, editing, multimodal understanding Text analysis, and speech as an agent modality Information extraction: ingestion, OCR, layout analysis, semantic and hybrid search IT TEACHES THE CURRENT NAMES Microsoft has renamed this stack twice. Azure AI Studio is now Microsoft Foundry. Cognitive Services are now Foundry Tools. Material that still uses the old names is out of date, and this bank uses the current ones throughout. WRITTEN FOR AN ENGINEER This is an associate-level developer exam that assumes Python experience. The questions are about design decisions and tradeoffs - which service, which deployment, which control - rather than definitions. BALANCED TO THE REAL EXAM Questions are distributed across the five skill areas in the exam's published proportions, so study time lands where the questions actually are. BUILT FOR FLIGHTS All 250 questions, their answers and every explanation ship inside the app. Practice never touches the network, never streams and never checks an account, so airplane mode behaves exactly like full signal. The only part of the app that uses a connection is the optional News tab, which reads a public RSS feed of AI news. It caches what it last loaded, so it still shows something offline, and nothing else depends on it. ALSO INCLUDED Exam Pace Timer, optional and on by default. A non-enforced two-minute countdown per question, approximating the pace of a two-hour exam, so you learn to feel the clock before exam day. It never locks you out and never auto-submits, and it can be switched off in one tap. Optional daily study reminder, scheduled on your device. Progress tracking: streak, best score, full attempt history, stored on your device. A review queue that brings back missed questions and releases them once you have them right.
