What's changed: (1) Fixed out-of-area distractors in nine mini-quizzes: NSG, TDE and Azure Key Vault are outside the official scope and were replaced with real features from the same Copilot/agent administration area (license assignment, PAYG billing policies, Copilot Analytics, prompt management, user access configuration, approval process, agent creation and monitoring), matching the fix applied to questions ab900-059/062/065/066/067/068/069/070/071. (2) Removed paragraph p-intune from section 2: Microsoft Intune appears in neither the skills measured nor the audience profile (inherited from the predecessor MS-900) and is unrelated to the subject of this section, Copilot administration. Question ab900-081, which carried the same inheritance, was likewise replaced with an official topic (creating an agent). / Section 2 now describes billing policies concretely, per Microsoft Learn (pay-as-you-go/setup): the Azure subscription and resource group charged, the users/groups in scope, a budget that notifies rather than caps, activation by connecting the policy to a pay-as-you-go service, the roles required to create one, and the 50-per-tenant limit. Mini-quiz q2 was rebuilt to match the corrected ab900-064 (distractors are now real features in the same Copilot administration area). Added per-section figures (cert-figure-retrofit). New AB-900 Chapter 3 (Domain 3 "Copilot and agent administration": capabilities = Copilot vs agents/monthly-PAYG/enable-disable/Researcher-Analyst-custom agents; Copilot admin = license assignment/PAYG billing policies/Copilot Analytics usage-adoption/prompt management; agent admin = user access config/creation/approval process/monitoring via M365 and Power Platform admin centers)
3.1Features of Copilot and agents
Understand the difference between Copilot and agents’ built-in capabilities, Copilot license models (monthly vs pay-as-you-go including SharePoint), which features can be enabled/disabled, and use cases for Researcher, Analyst, and custom agents.
Microsoft 365 Copilot is an AI assistant embedded in apps like Word, Excel, Outlook, and Teams. Agents are customizable AIs specialized for specific tasks or knowledge that work semi-autonomously, extending Copilot. Admins must understand their capabilities, licensing, and enablement scope to deliver them.
3.1.1License models: monthly vs pay-as-you-go
Copilot has two billing models: a monthly license (a fixed per-user monthly fee for Copilot broadly) and pay-as-you-go (PAYG) (charged by usage, applied to specific uses such as SharePoint agents). Monthly suits steady, heavy users; PAYG suits variable or limited usage. Admins choose based on target users and scenarios.
3.1.2Researcher, Analyst, and custom agents
- Researcher: a built-in agent for deep research (investigate, summarize, analyze) across multiple sources.
- Analyst: a built-in agent that supports analyst-style tasks such as data analysis and visualization.
- Custom agents: agents you build specialized for org-specific knowledge or processes (e.g., internal FAQ, request workflows).
Admins can enable/disable certain Copilot features (adjusting what is offered to match org policy) and control agent availability. Governing "which features to whom" is central to safe deployment.
| Item | Characteristic | When to use |
|---|---|---|
| Copilot (built-in) | AI assistant in apps | Everyday productivity |
| Agents | Specialized, semi-autonomous | Specific tasks/knowledge |
| Monthly license | Fixed monthly | Steady, heavy use |
| Pay-as-you-go (PAYG) | Charged by usage | Variable/limited use (e.g., SharePoint) |
| Researcher | Deep research | Investigate/summarize/analyze |
| Analyst | Data analysis | Analyze/visualize |
Watch the mix-ups: (1) Copilot (general assistant embedded in apps) vs agents (specialized, semi-autonomous, customizable). (2) monthly (fixed) vs PAYG (by usage; SharePoint, etc.). (3) Researcher (deep research) vs Analyst (data analysis)—don’t confuse use cases.
Common: requirement → feature/model. E.g., "do deep cross-source research" = Researcher; "support data analysis" = Analyst; "build an AI specialized in internal knowledge" = custom agent; "variable usage, pay per use" = PAYG; "everyone uses it constantly, fixed monthly" = monthly license.
3.1.3Section summary
- Copilot = general AI embedded in apps; agents = specialized, semi-autonomous, customizable
- Licensing: monthly (fixed) vs pay-as-you-go (by usage; SharePoint, etc.)
- Researcher (deep research) / Analyst (data analysis) / custom agents (org-specific)
