Pass the Microsoft Microsoft 365 Certified: Copilot and Agent Administration Fundamentals AB-900 Questions and answers with CertsForce

The correct answers are C and D . Microsoft Learn explains that agents created with Agent Builder in Microsoft 365 Copilot allow you to define specific instructions that extend Microsoft 365 Copilot for a business scenario. Microsoft also documents that you can add knowledge sources such as specific public websites and SharePoint content so the agent can reason over targeted information instead of relying only on the default chat experience. Those two capabilities directly match the needs in options C and D.

Option A is incorrect because grouping chats is a Copilot notebook scenario, not the reason to build an agent. Option B is incorrect in the context of creating an agent in the Microsoft 365 Copilot app . Agent Builder supports declarative agents with instructions, knowledge, and capabilities, but Microsoft Learn describes custom AI model control as part of custom engine agents built with tools such as Copilot Studio, SDKs, or Foundry, not as a standard Agent Builder feature in the Microsoft 365 Copilot app. Therefore, when the task is specifically to create an agent in the app, the valid reasons are custom instructions and reasoning over a specific website .

The correct answer is A. Data access governance in the SharePoint admin center . Microsoft Learn documents Data access governance reports in the SharePoint admin center as the reporting solution used to understand data exposure, including permission structure and sharing link activity . Microsoft specifically states that the site permissions snapshot report provides visibility across SharePoint and OneDrive sites , helping administrators understand current permissions exposure, and that separate reports are created for SharePoint and OneDrive . Microsoft also documents sharing links activity reports as part of Data access governance for monitoring link-sharing activity, and notes that OneDrive support is available through PowerShell for those reports. Together, this is the Microsoft reporting capability aligned with permissions and active sharing links for OneDrive content.

The other options do not fit this requirement. Microsoft 365 admin center reports focus mainly on usage and activity reporting, not detailed permissions and sharing-link governance. Defender Audit is for security investigation activity, and Purview eDiscovery is for legal and investigative content search, not for generating OneDrive permissions and sharing-link governance reports. Therefore, the best Microsoft-documented answer is Data access governance in the SharePoint admin center .
