Perform basic administrative tasks for Copilot and agents1 / 5

You want a set of company-approved prompts to appear as suggested prompts at the top of Copilot Chat for all users in your tenant. What do you do in the Microsoft 365 admin center?

AlexFull explanation from Alex

Organizational prompts let admins publish company-tailored prompts tenant-wide from the Microsoft 365 admin center (Copilot > Prompts), where you can create, edit, delete, import/export, and pin prompts. Pinning surfaces frequently used or priority prompts to the top of the list as suggested prompts in Copilot Chat, with a maximum of four pinned at once; changes take about 3 hours to appear. This is the 'manage prompts (save/share/schedule/delete)' administrative task at the org level. Exam tip: pinning is capped at four and drives the suggested-prompt experience; deletion of organizational prompts is permanent, so export first. The doc concept is 'organizational prompts' and pinning in the admin center.

A finance analyst wants Microsoft 365 Copilot to examine raw data across several Excel spreadsheets, run calculations, and generate charts and insights like a skilled data analyst. Which built-in capability best fits this task?

AlexFull explanation from Alex

The Analyst agent is a prebuilt reasoning agent in Microsoft 365 Copilot that acts like a skilled data analyst. It can work across multiple spreadsheets, run code (Python) to perform advanced analysis, and produce insights and visualizations from raw data. This makes it the right fit for tasks such as reviewing a monthly close file and flagging line items that look out of line with prior months. A common exam distinction: Researcher is for multi-step research and cited reports, while Analyst is for crunching raw numbers and visualizing results. Both are first-party reasoning agents available to users with a Microsoft 365 Copilot license and are invoked from Copilot Chat. The doc concept to remember is that Analyst 'runs code' and creates visualizations, which is what separates it from a plain chat answer.

An administrator wants to enable the Microsoft Copilot Dashboard so leaders can view adoption insights. Which statement correctly reflects how access is set up and determined?

AlexFull explanation from Alex

The Copilot Dashboard lives in the Viva Insights web app (and Teams Viva Insights app). An AI Administrator enables it from the Microsoft 365 admin center and manages its settings, such as minimum group size for privacy. Users identified as senior leaders by their Microsoft Entra ID data, plus enabled managers, receive automatic access; those users can delegate access to others, and Microsoft 365 global admins and Viva Insights Analysts with global partition access can also reach the reports. Data is typically available within seven days of license assignment. Exam tip: AI Administrator enables it; automatic access is driven by Entra ID data (leaders/managers), with delegation for everyone else.

SharePoint sharing limits

View the full question

Your organization-level SharePoint sharing setting is New and existing guests. The Marketing team's site must be locked down so that its content can never be shared outside the organization, while all other sites keep the current behavior. As SharePoint Administrator, where do you make this change?

Understand the correct answer.

SharePoint admin center > Sites > Active sites > select the Marketing site > Settings tab > More sharing settings > Only people in your organization

The site can block external sharing even when the organization permits guests.

Frequently asked questions

Your preparation

How much study time should I plan for AB-900?

For planning, Pass-IT estimates roughly 10–30 hours. Relevant experience may put you toward the lower end; starting from scratch may put you toward the higher end. Your needs may fall outside this range. This is not a time requirement from Microsoft or a promise that you will be exam-ready within that time.

Do you need admin experience before AB-900?

No. Microsoft sets no prerequisite and this is a fundamentals exam, written for people who need the vocabulary rather than the console skills. The catalog budget is around 20 hours, the shortest of any Microsoft exam we cover.
