Review practical agent-building decisions with 150 independently authored questions across two distinct practice tests. This pack is designed for developers and advanced makers preparing to study the AB-620 scope, or reviewing the reasoning behind reliable Copilot Studio solutions.  The coverage follows the official AB-620 guide reviewed on September 21, 2026. The guide covers planning and configuring agent solutions, integrating and extending agents, and testing and managing agents. Product experiences, licensing, previews, and integration availability can change. Check current official documentation for your environment and exam date. Questions focus on the standard Copilot Studio agent concepts and broadly applicable integration principles; they do not assume every preview feature is available in every tenant.  Each test contains 75 single-answer questions: 25 on planning and configuration, 32 on integrations and extensions, and 18 on evaluation and lifecycle management. Every option includes an explanation. The second test uses a separate question set. Each test allows 120 minutes and uses an 80% study target; these are independent practice settings, not a claim about official exam scoring or format.  Planning questions cover identity, access boundaries, channels, reusable topics, variables, typed inputs, agent flows, approval gates, Adaptive Cards, HTTP responses, prompts, and recovery paths. Integration questions explore connector selection, live data versus indexed knowledge, MCP and A2A roles, custom APIs, computer use, Fabric and Foundry agents, retrieval quality, permissions, telemetry, and trustworthy interpretation of tool results.  Evaluation and management questions emphasize representative test sets, reference quality, multi-turn behavior, negative cases, regression checks, production identities, solutions, environment variables, connection references, deployment pipelines, configuration drift, and recovery planning. Many questions test engineering judgment and common failure modes rather than memorization of interface labels.  Use the first test to identify gaps, review each explanation, and confirm unfamiliar capabilities in Microsoft Learn. Then take the second test to check your reasoning with different scenarios. Hands-on work remains important: this is a concept-review question pack, not a lab environment, video course, or exact exam simulation.  All questions are original. No actual, recalled, leaked, or copied certification exam questions are included. No exam voucher, certification award, or pass guarantee is included.
