PL-900 Practice Question: Demonstrate the capabilities of Power Automate

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The site address in the HTTP request is incorrect.
If the site address in the 'Send an HTTP request to SharePoint' action is incorrect, the request cannot reach the target SharePoint list, and the update fails. Option A is wrong because the HTTP request action is indeed available and can update items. Option B is wrong because the flow typically runs under the creator's or configured connection credentials; permission is usually not the issue unless explicitly insufficient. Option C is wrong because the action can update list items when the URI and method are correct.
