PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
A company has deployed a custom copilot built with Microsoft Copilot Studio. Users report that the copilot sometimes provides outdated information. The knowledge sources are SharePoint sites and public websites. The copilot uses Generative AI to formulate answers. What should the administrator do to improve the accuracy of the copilot's responses?
⚠ Common exam trap
It's easy for candidates to confuse user-facing features like 'Show citations' with data freshness mechanisms, or assume that disabling generative AI will fix accuracy issues, when in fact the root cause is the static nature of the knowledge snapshot.
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
✓
Refresh the knowledge sources periodically
The copilot's knowledge sources (SharePoint sites and public websites) are not automatically refreshed in real time. By periodically refreshing these sources, the administrator ensures the copilot's generative AI has access to the most current content, directly addressing the issue of outdated information.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable the 'Show citations' option
Why it's wrong here
Citations show sources but don't update the data.
- ✗
Reduce the number of topics
Why it's wrong here
Fewer topics don't address outdated information.
- ✓
Refresh the knowledge sources periodically
Why this is correct
Refreshing knowledge sources ensures the copilot uses current data.
- ✗
Turn off Generative AI for responses
Why it's wrong here
Turning off Generative AI would prevent answer generation, not improve accuracy.
