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
✓
When a file is created
The 'When a file is created' trigger is designed to start a flow when a new file appears in a SharePoint library. Option A is wrong because 'When a file is deleted' triggers on file removal, not creation. Option B is wrong because 'When a file is modified' triggers on updates, not new files. Option D is wrong because 'When a file is created or modified' includes modification events, which are not required for the specified requirement.

Variation 1. A company wants to automate sending a welcome email to new employees after they are added to a SharePoint list. Which type of trigger should be used in the Power Automate flow?
easy- A.For a selected item - SharePoint
- B.Recurrence
- C.Start and wait for an approval
- ✓ D.When an item is created - SharePoint
Why D: The 'When an item is created - SharePoint' trigger is the correct choice because it initiates the flow automatically whenever a new item (in this case, a new employee record) is added to the specified SharePoint list. This event-driven trigger eliminates the need for manual intervention, making it ideal for automating the welcome email process immediately upon creation.
