PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A team wants a Power Automate cloud flow to run whenever a new response is submitted in a Microsoft Forms survey. The flow should then add the respondent's email address to a Microsoft 365 group. Which trigger should the flow use?
⚠ Common exam trap
The trap here is choosing a trigger that fires on form creation rather than on response submission; only the response-submitted trigger reacts to each completed survey.

Correct answer & explanation
✓
When a new response is submitted
The Microsoft Forms connector exposes a dedicated trigger that fires on each new response submission. By using it and then calling 'Get response details', the flow can extract the respondent's email address and pass it to an action that adds the user to the Microsoft 365 group, fully automating the workflow.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
When a new response is submitted
Why this is correct
The Microsoft Forms connector provides the 'When a new response is submitted' trigger, which fires each time someone completes the specified form. This directly matches the requirement to react to new survey responses. After the trigger, you can add an action such as 'Get response details' to retrieve the respondent's email and then add them to the group.
- ✗
When a new email arrives (V3)
Why it's wrong here
This Outlook trigger fires when email is delivered to a mailbox. While Forms can send notification emails, the trigger would fire on any incoming mail, not specifically on form submissions, and it would not reliably capture the respondent's email address. It is the wrong event source for reacting to survey responses.
- ✗
When a form is created
Why it's wrong here
This trigger fires only when a new form is created in Microsoft Forms, not when a response is submitted. Using it would mean the flow runs once at form creation and never again, so no respondent would ever be added to the group. It does not satisfy the requirement to react to each submission.
- ✗
When a file is created (properties only)
Why it's wrong here
This SharePoint trigger responds to new files in a document library. Microsoft Forms responses are not stored as files in a library by default, so this trigger would not fire when a survey is submitted. It is unrelated to the Forms response event and would never add respondents to the group.
