PL-900 Practice Question: Demonstrate the capabilities of Power Automate
You are building a flow to automate the process of copying files from one SharePoint document library to another when a file is added. The flow should also send an email notification to a team. You have created the flow, but it is not triggering when a new file is added. What should you check first?
⚠ Common exam trap
The trap is overthinking the problem by jumping to licensing or environment issues; the exam expects you to recognize that a non-firing trigger almost always points to trigger configuration (wrong site/library) as the first thing to verify.

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
✓
Check the trigger configuration to ensure the correct library and site are selected
When a flow does not trigger on file creation, the most common cause is a misconfigured trigger — the wrong site address, library name, or folder path selected in the 'When a file is created' trigger. Verifying the trigger configuration is the fastest first diagnostic step because it directly controls whether the flow fires. Other checks (licensing, environment state, target library) are valid but less likely to be the root cause of a non-firing trigger.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify that the flow owner has a valid Power Automate license
Why it's wrong here
A missing licence blocks the owner from saving or running the flow, but the trigger would still fire and log a run; a flow that never triggers points to the trigger's connection, folder path or condition. Licence checks matter when the flow errors immediately on creation or manual run.
- ✗
Confirm that the target library exists and is accessible
Why it's wrong here
The target library only matters once the flow runs and copies the file; a trigger that never fires produces no run history at all, so the destination is irrelevant. Verifying destination access is correct when runs start but the copy action fails with a not-found or access-denied error.
- ✗
Ensure that the environment is not in a disabled state
Why it's wrong here
A disabled environment stops all flows and typically shows environment-level errors, whereas a single non-triggering flow usually indicates a trigger configuration issue. Environment state is the right check when every flow in that environment stops simultaneously after an administrative change.
- ✓
Check the trigger configuration to ensure the correct library and site are selected
Why this is correct
A SharePoint 'when a file is created' trigger only fires for the specific site and document library named in its configuration. If those fields reference the wrong library, additions elsewhere never start the flow, so verify them first.
