PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
A company has a Microsoft Copilot Studio copilot that answers product questions by searching a public product catalog website. The copilot currently uses generative answers and returns inconsistent results. The company wants the copilot to use only approved content from a specific internal SharePoint site. What should the maker configure to restrict the copilot's generative answers to that SharePoint site?
⚠ Common exam trap
The trap here is thinking that changing the publishing channel or adding static topics will control generative answer grounding, when knowledge sources are the actual mechanism.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the SharePoint site as a knowledge source in the copilot's generative answers settings.
Generative answers in Microsoft Copilot Studio are grounded in knowledge sources that the maker configures. Adding a specific SharePoint site as a knowledge source and ensuring no public sources are enabled restricts the copilot to approved internal content. This provides accurate, consistent answers based on the organization's authoritative product information rather than unpredictable public web results.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Publish the copilot to Microsoft Teams and configure a Teams channel data loss prevention policy.
Why it's wrong here
Publishing to Microsoft Teams changes the delivery channel but does not control which knowledge sources the copilot uses for generative answers. Data loss prevention policies in Teams govern information sharing, not copilot knowledge grounding. This option does not restrict the copilot to the internal SharePoint site and therefore fails to meet the scenario's requirement for approved content only.
- ✗
Disable generative answers entirely and rely on the fallback topic.
Why it's wrong here
Disabling generative answers would stop the copilot from using AI to answer questions and would force it to use only authored topics. The fallback topic typically returns a generic message and would not provide answers from the SharePoint site. This does not satisfy the goal of grounding answers in approved internal content, and it would degrade the copilot's ability to answer product questions.
- ✓
Add the SharePoint site as a knowledge source in the copilot's generative answers settings.
Why this is correct
Microsoft Copilot Studio allows makers to add specific knowledge sources, such as SharePoint sites, to ground generative answers. By adding only the approved internal SharePoint site as a knowledge source and removing or disabling the public website source, the copilot will generate answers based solely on that content. This directly satisfies the requirement to restrict responses to approved internal material.
- ✗
Create a topic with trigger phrases for each product question and hard-code the answers.
Why it's wrong here
Hard-coding answers in topics would restrict responses to predefined content, but it would not leverage the SharePoint site as a dynamic knowledge source. This approach is labor-intensive and does not scale as product information changes. The scenario asks to restrict generative answers to a SharePoint site, not to replace generative answers with static topics, so this option does not meet the requirement.
