Copilot & Agent Admin AB-900: 150 Practice Questions

Build a clear understanding of Microsoft 365 Copilot and agent administration fundamentals with 150 independently authored questions across two separate practice tests. This beginner-focused pack helps you distinguish related services, identify an appropriate administrative control, and explain why a proposed action fits a business requirement.

Version note: this pack follows the published AB-900 objectives dated October 14, 2026. That update is upcoming as of September 20, 2026. Microsoft identifies a minor change in the core security features area. Check the official study guide for the version that applies to your exam date. Product interfaces, names, licensing, and feature availability can change.

Each test contains 75 single-answer questions: 25 on Microsoft 365 services and identity, 28 on data protection and governance, and 22 on Copilot and agent administration. You will review practical distinctions such as authentication versus authorization, a distribution group versus a shared mailbox, sensitivity versus retention, data discovery versus activity investigation, and license assignment versus demonstrated adoption.

The questions also explore how to review access before an AI rollout, investigate policy alerts without jumping to conclusions, evaluate an agent's requested permissions, maintain authoritative knowledge sources, monitor consumption, and manage ownership throughout an agent's lifecycle. Every answer option has its own explanation so that an incorrect choice becomes a useful learning opportunity.

Use the first test to identify weak areas. Read every explanation, consult Microsoft Learn for topics that need reinforcement, and practice relevant administration in an appropriately licensed test environment. Then use the second, distinct test to check your reasoning on another set of situations. Both tests allow 90 minutes and use an 80% study target; these are practice settings, not the official exam duration or Microsoft's scaled passing score.
