Medium AB-900 practice questions

A compliance analyst at Contoso has deployed sensitivity labels across the organization and wants to review how users are interacting with labeled and classified content over the past week — for example, which files had labels applied, changed, or downgraded, and where sensitive information types were detected. Which Microsoft Purview tool should the analyst use to view this historical activity data?

A maker in your organization uses Copilot Studio to build a custom agent that answers HR policy questions by grounding on an internal SharePoint site. Before the agent becomes available to end users across the tenant, your governance policy requires that an administrator formally review and authorize it. As the Microsoft 365 administrator, where do you go to review and approve this maker-submitted agent before it is broadly published?

A company just purchased 200 Microsoft 365 Copilot licenses. The IT administrator wants to ensure that every new employee who joins the Marketing department automatically receives a Copilot license without manual intervention each time someone is hired. Which approach should the administrator use in the Microsoft 365 admin center?

A compliance officer reports that a confidential file stored in SharePoint Online was deleted last week, and management wants to know exactly which user account performed the deletion and when. As the Microsoft 365 administrator, which feature should you use to find this information?

A compliance administrator wants to ensure that any document containing credit card numbers stored across all SharePoint sites and OneDrive accounts is automatically classified and encrypted, even for files that users created months ago and never manually labeled. Which Microsoft Purview capability should be configured to meet this requirement?

A financial services organization deploys Microsoft 365 Copilot. The compliance team is concerned that employees might use Copilot to draft emails or Teams messages that share confidential deal information inappropriately, use offensive language, or make unauthorized promises to clients.

Which Purview solution should they configure?

Your organization has enabled multi-factor authentication for all users, but the security team notices that several accounts are still being accessed through older email clients that bypass MFA prompts. These clients use protocols like IMAP and POP3 that do not support modern authentication. As the Microsoft 365 administrator, what should you configure to prevent these sign-ins while allowing modern clients to continue working?

Your organization wants to ensure that users can access SharePoint Online and Exchange Online only from devices that are enrolled and marked as compliant in Microsoft Intune. Users on unmanaged personal devices should be blocked. Which Microsoft Entra ID feature should you configure to enforce this requirement?

A user reports they were blocked from signing in to Microsoft 365 this morning. In the Microsoft Entra admin center, you see the sign-in was flagged as high risk because it originated from an atypical location using valid credentials. Your organization has a conditional access policy that blocks high-risk sign-ins. Which Microsoft Entra ID capability generated the high-risk flag that triggered this policy?

Contoso has published a custom declarative agent for its HR department. The IT admin needs to ensure that only members of the HR team can see and use this agent, while all other employees should not have access to it.

A finance manager wants a Copilot agent that can take raw sales data from an Excel file, run advanced statistical calculations, generate visualizations, and produce a forecast. The finance manager asks which built-in Copilot agent is designed for this kind of high-fidelity, code-driven data analysis. Which agent should you recommend?

A financial operations team wants a Microsoft 365 Copilot capability that can perform advanced, multi-step data analysis on raw sales spreadsheets—including running Python code to generate visualizations and statistical models directly from the data they provide. As the administrator, which built-in Copilot agent should you direct them to use for this scenario?

A financial planning team asks you which built-in Copilot agent to use for a recurring task: they need to take a large raw sales dataset stored in Excel, run advanced statistical calculations and code-based data manipulation on it, and produce a chart with insights.

An administrator has published several custom agents to the organization over the past year. Leadership wants to identify which agents are no longer being used so they can be retired to reduce clutter and administrative overhead. Where in the Microsoft 365 admin center should the administrator look to review agent usage trends and lifecycle status to make this decision?

A sales team lead has crafted an effective prompt in Microsoft 365 Copilot that summarizes weekly opportunity pipeline updates. She wants the entire sales department to be able to discover and reuse this exact prompt from within Copilot, rather than each person recreating it. What is the most appropriate way for her to accomplish this?

You are a Microsoft 365 administrator. Leadership wants a report that shows how many licensed users are actively using Copilot in Word, Excel, Teams, and Outlook over the last 28 days, without configuring any additional tools or add-ins. Which admin experience should you use to retrieve this usage data with the least effort?

A Microsoft 365 admin needs to save a frequently used prompt so a specific project team can reuse it, and also wants that prompt to run automatically every Monday morning to generate a weekly status summary. Which combination of prompt management actions should the admin use?

As a Microsoft 365 administrator, you need to provide leadership with a report showing which Copilot features (such as Copilot in Teams, Word, and Outlook) employees are actively using, along with the number of users who were assigned licenses but have never used Copilot. You want the fastest built-in option that surfaces per-app active usage and adoption trends without building custom reports. Which tool should you use?

A department lead asks you to share which specific Copilot features (Chat, summaries in Teams, Word drafting) her team is actually using each week, so she can target training. As the Microsoft 365 admin, where should you go to produce a report broken down by app-level Copilot usage and active users over time?

A department head asks the Microsoft 365 administrator for a solution that lets employees ask questions grounded specifically in the department's internal SharePoint knowledge base and policy documents, with responses tailored to their unique terminology. The out-of-the-box Microsoft 365 Copilot chat experience is already deployed org-wide. What should the administrator recommend to meet this specific requirement?
