PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
A company wants to create a custom copilot that answers employee questions about IT policies. The copilot must use existing SharePoint documents as a knowledge source. Which feature of Microsoft Copilot Studio should the company use?
⚠ Common exam trap
It's easy for candidates to confuse the 'Generative AI feature' (which enables AI responses) with the specific mechanism to provide source data, or they mistakenly think Copilot for Microsoft 365 is a feature within Copilot Studio for adding knowledge sources, when it is a separate product.
