Overview

Perform basic administrative tasks for Copilot and agents is the domain that most distinguishes AB-900, covering the day-to-day administration of Copilot and agents. It has three objective groups. Understanding Copilot and agent capabilities covers comparing built-in Copilot and agent capabilities, the monthly license versus pay-as-you-go model including SharePoint, which features can be enabled or disabled, and use cases for Researcher, Analyst and custom agents. Performing Copilot tasks covers assigning Copilot licenses, monitoring and managing pay-as-you-go billing, monitoring usage and adoption with Copilot Analytics and the Microsoft 365 admin center, and managing prompts. Performing agent tasks covers configuring user access to agents, creating an agent, understanding the approval process, and monitoring agents through the Microsoft 365 admin center and the Power Platform admin center.

At 25–30%, this domain tests the practical administration of an AI-enabled tenant. The exam rewards knowing the licensing models, how to monitor adoption, and the agent lifecycle from creation through approval to monitoring.

How it's tested

AB-900 questions in this domain describe a Copilot or agent administration need and ask how to license, monitor or manage it. Read the full scenario and all options before choosing, picking the feature or tool that most precisely matches what is described.

  • Licensing model

    A Copilot usage pattern is described, and you choose the monthly license or pay-as-you-go model.

  • Monitor adoption

    A usage-visibility need is described, and you choose Copilot Analytics or the admin center.

  • Agent lifecycle

    An agent administration need is described, and you apply access, creation, approval or monitoring.

Reasoning it through

An organization wants to let a department use a Copilot capability occasionally and pay only for what it uses, rather than committing to a per-user monthly license for everyone. A monthly Copilot license charges a fixed amount per user regardless of usage. A pay-as-you-go billing model charges based on consumption, which suits occasional or variable use, so the administrator configures pay-as-you-go billing, the consumption-based option the exam expects.

Functional groups 3

Official functional groups from the Microsoft outline, in outline order.

3.1 Understand features and capabilities of Copilot and agentsCopilot and agent capabilities, licensing models, enabling features, and use cases.
What it means
This covers comparing the built-in capabilities of Copilot and agents, comparing the Copilot monthly license model to pay-as-you-go including SharePoint, identifying which Copilot features can be enabled or disabled, and use cases for Researcher, Analyst and custom agents.
What to understand
Copilot provides AI assistance across Microsoft 365, and agents extend it for specific tasks. Licensing is either a per-user monthly subscription or consumption-based pay-as-you-go. Administrators can enable or disable specific features. Researcher and Analyst are specialized capabilities, and custom agents address bespoke needs.
How it shows up
A capability or licensing need is described, and you must choose the model or identify the use case.
Common confusion
Confusing the monthly Copilot license with the pay-as-you-go model; monthly is a fixed per-user subscription, while pay-as-you-go is consumption-based.
3.2 Perform basic administrative tasks for CopilotAssign licenses, manage billing, monitor adoption, and manage prompts.
What it means
This covers assigning Copilot licenses, monitoring and managing Copilot pay-as-you-go billing policies, monitoring Copilot usage and adoption with Copilot Analytics and the Microsoft 365 admin center, and managing prompts including saving, sharing, scheduling and deleting.
What to understand
Copilot licenses are assigned to users, directly or via groups. Pay-as-you-go billing policies control consumption-based spend. Copilot Analytics and the admin center show adoption and usage. Prompt management lets administrators and users save, share, schedule and delete prompts to standardize and govern AI use.
How it shows up
A Copilot administration need is described, and you must choose license assignment, billing management, adoption monitoring or prompt management.
Common confusion
Confusing adoption monitoring tools; Copilot Analytics and the Microsoft 365 admin center both report usage at different levels.
3.3 Perform basic administrative tasks for agentsConfigure access, create an agent, understand approval, and monitor the lifecycle.
What it means
This covers configuring user access to agents, creating an agent, understanding the approval process for agents, and monitoring agents including usage, operational insights and the agent lifecycle, using the Microsoft 365 admin center and the Power Platform admin center.
What to understand
Agents are managed through a lifecycle: administrators configure who can access them, agents are created, an approval process governs their release, and they are monitored for usage and operational health. The Microsoft 365 and Power Platform admin centers provide agent administration and insights.
How it shows up
An agent administration need is described, and you must apply access configuration, creation, approval or monitoring.
Common confusion
Overlooking the agent approval process; agents go through approval before broad use, not straight from creation to everyone.

  3. Skip agent approval

    What candidates pick
    Release a new agent to all users straight after creation.
    Why it looks right
    It is faster.
    Why it's wrong
    Agents go through an approval process before broad use as part of their governed lifecycle.

    Clue to watch for A new agent is being rolled out organization-wide.

  4. No adoption monitoring

    What candidates pick
    Deploy Copilot and not track whether it is used.
    Why it looks right
    Deployment seems complete.
    Why it's wrong
    Copilot Analytics and the admin center monitor usage and adoption, which guides rollout and value.

    Clue to watch for The organization wants to understand Copilot usage.

  5. Researcher is Analyst

    What candidates pick
    Use the Analyst capability for a deep research task.
    Why it looks right
    Both are specialized.
    Why it's wrong
    Researcher addresses research use cases; Analyst addresses data analysis.

    Clue to watch for The task is research versus data analysis.

Answer framework

For any Domain 3 scenario, use these steps to find the answer AB-900 expects.

  1. Identify whether the need is understanding capabilities and licensing, a Copilot task, or an agent task.
  2. For licensing, choose the monthly per-user license for steady use or pay-as-you-go billing for occasional or variable use.
  3. For Copilot administration, assign licenses, manage pay-as-you-go billing, monitor adoption with Copilot Analytics and the admin center, and manage prompts.
  4. For agents, configure user access, create the agent, follow the approval process before release, and monitor usage and lifecycle in the Microsoft 365 and Power Platform admin centers.
  5. Match specialized capabilities to use cases, choosing Researcher, Analyst or a custom agent as the task requires. Where two options seem to fit, pick the one that most precisely matches the scenario.

Study strategy

This domain is what makes AB-900 an AI-administration exam, so focus on the practical tasks. Start with capabilities and licensing: understand how Copilot and agents differ, and firmly distinguish the per-user monthly license from consumption-based pay-as-you-go, which is a frequent decision point.

Next, learn the Copilot administration tasks: assigning licenses, managing pay-as-you-go billing, monitoring adoption with Copilot Analytics and the admin center, and managing prompts. Then learn the agent lifecycle, access configuration, creation, approval and monitoring, across the Microsoft 365 and Power Platform admin centers, and do not skip the approval step.

Because the exam is practical for a fundamentals level, exploring the Copilot and agent administration experiences in a trial tenant helps. This is the final domain, so finish with full practice tests spanning all three, and remember the whole exam centers on administering an AI-enabled tenant. AB-900 is more hands-on than older fundamentals exams, so use a free Microsoft 365 developer tenant to explore the admin experiences, and review missed practice questions by group to find weak spots.
