A company has configured the copilot as shown in the exhibit. Users report that the copilot is not answering questions about HR policies that were updated in the SharePoint site today. What is the most likely cause?

⚠ Common exam trap

It's easy for candidates to confuse the refresh interval setting with authentication or AI enablement, assuming that any failure to answer new content must be a permissions or AI feature issue, rather than recognizing that the copilot simply hasn't re-indexed the updated source yet.

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

✓

The knowledge source refresh interval is set to weekly

The copilot's knowledge source refresh interval is set to weekly, meaning it only re-indexes the SharePoint site every seven days. Since the HR policies were updated today, the copilot is still using the stale, pre-update content and cannot answer questions about the new policies until the next scheduled refresh occurs.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The public website refresh is set to daily
Why it's wrong here
The public website refresh schedule governs external web content crawling, not SharePoint site indexing. HR policies live in SharePoint, whose content is indexed on its own cycle. A daily public refresh setting would be relevant only when the copilot sources answers from an internet-facing site.
✗
Authentication is not properly configured
Why it's wrong here
Broken authentication would block users from reaching the copilot entirely, producing sign-in errors rather than stale answers. The reported behaviour is partial: some HR content answers, recent updates do not. Authentication misconfiguration is the cause when no user can authenticate or query the copilot at all.
✓
The knowledge source refresh interval is set to weekly
Why this is correct
Copilot answers from indexed SharePoint content, and a weekly refresh interval means today's HR policy updates have not yet been crawled into the index. Shortening the refresh interval, or triggering reindexing, makes the new content answerable.
✗
Generative AI is disabled
Why it's wrong here
Disabling generative AI would stop the copilot answering any question, not merely recent HR content. The stem describes selective failure on today's updates, which points to search indexing latency. Generative AI being off is the cause when the copilot returns no responses whatsoever.
