PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A Power Automate flow uses a 'When an item is created' trigger on a SharePoint list. After moving the list to a different site, the flow no longer triggers. What is the most likely reason?
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 trigger still references the old site and list ID.
The 'When an item is created' trigger is bound to the original site URL and list ID. Moving the list to a different site does not automatically update the trigger's connection, so the flow continues to listen for changes on the old location and fails to trigger for the new one. Option B is incorrect because the trigger can work across sites if updated; the issue is the stale reference. Option C is incorrect because the flow is not automatically disabled during the move. Option D is incorrect because re-authentication is not related to the change in location.
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 trigger still references the old site and list ID.
Why this is correct
Moving a SharePoint list changes its site and list identifiers. The trigger stores the original site URL and list GUID, so it polls a location that no longer exists and never fires for new items.
- ✗
The trigger does not support cross-site operations.
Why it's wrong here
Triggers are bound to a specific list's site URL and ID; moving the list changes that identity, so the existing trigger points at a non-existent resource. Cross-site triggering itself is supported. The option tempts because site scoping feels like a limitation, but the real cause is the stale connection reference.
- ✗
The flow was disabled during the move.
Why it's wrong here
Moving a list does not disable its flows; the trigger's stored site and list identifiers simply no longer resolve. It tempts because disabled flows are a frequent cause of silent non-triggering, and would be correct if the flow had been switched off manually.
- ✗
The SharePoint connector requires re-authentication.
Why it's wrong here
Re-authentication failures block the whole flow with a visible connection error, not silent non-triggering after a move. It tempts because expired credentials commonly break SharePoint flows, and would be correct if the run history showed an authentication failure.
