PL-900 Demonstrate the capabilities of Power Apps Practice Question
A company uses Microsoft Power Apps to build a leave request application. The app uses SharePoint as the data source. Users report that when they submit a leave request, the app sometimes fails to save the data and shows a generic error. Which should you investigate first?
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
✓
Verify the connection to the SharePoint data source.
Generic errors when saving data in Power Apps often indicate a problem with the data source connection, such as network interruption or permission changes. Option A is incorrect because clearing browser cache and cookies typically affects app loading performance, not data submission. Option C is incorrect because delegation issues in Power Apps affect data retrieval (e.g., filtering large lists), not the ability to save new records. Option D is incorrect because formula syntax errors usually produce specific error messages, not a generic save failure.
