Quick Answer
The correct answer is to refresh the knowledge sources periodically. This is because Microsoft Copilot Studio does not automatically sync changes from external sources like SharePoint sites or public websites in real time; the generative AI model relies on the last indexed snapshot of that data. Without a manual or scheduled refresh, the copilot will continue to generate responses from stale content, directly causing the outdated information users are reporting. On the PL-900 exam, this scenario tests your understanding of knowledge source management within Copilot Studio, often appearing as a distractor where candidates might incorrectly choose to retrain the AI model or adjust the topic triggers. A common trap is assuming generative AI automatically updates its training data, but the key is that knowledge sources are separate from the base model. Remember the memory tip: “Stale sources, stale answers—refresh to refresh the facts.”
This PL-900 practice question tests your understanding of demonstrate the capabilities of microsoft copilot studio. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 Users report that the copilot sometimes provides outdated information.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?
Enable the 'Show citations' option
Why wrong: Citations show sources but don't update the data.
Reduce the number of topics
Why wrong: Fewer topics don't address outdated information.
Refresh the knowledge sources periodically
Refreshing knowledge sources ensures the copilot uses current data.
Turn off Generative AI for responses
Why wrong: Turning off Generative AI would prevent answer generation, not improve accuracy.
Answer choices
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
Option C is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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.
Common exam traps
The trap here is that candidates 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.
Trap categories for this question
Command / output trap
Citations show sources but don't update the data.
Detailed technical explanation
Under the hood, Microsoft Copilot Studio stores a snapshot of the knowledge sources at the time of publishing. When a user asks a question, the generative AI model retrieves relevant chunks from this snapshot to formulate an answer. If the SharePoint site or public website content changes, the snapshot becomes stale until the administrator manually triggers a 'Refresh' or sets a schedule for automatic refresh. In a real-world scenario, a company with a frequently updated product documentation site would need daily refreshes to avoid surfacing deprecated specifications.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
