PL-900 Practice Question: Describe the business value of Microsoft Power Platform
Exhibit
Refer to the exhibit.
```json
{
"name": "New Employee Onboarding",
"triggers": {
"manual": true,
"schedule": {
"frequency": "Day",
"interval": 1,
"startTime": "2026-05-01T08:00:00Z"
}
},
"actions": [
{
"type": "CreateRecord",
"entityName": "Users",
"fields": {
"FirstName": "{{triggerOutputs()?['name']}}",
"Department": "IT"
}
},
{
"type": "SendEmail",
"to": "hr@contoso.com",
"subject": "New employee created",
"body": "User {{triggerOutputs()?['name']}} has been created."
}
]
}
```Refer to the exhibit. You are analyzing a Power Automate flow definition. The flow is intended to create a new user record in Dataverse and send an email notification when manually triggered or daily at 8 AM. However, when the flow runs on its schedule, it fails because the trigger output 'name' is empty. What is the most likely cause?
⚠ Common exam trap
The PL-900 exam often tests the misconception that all triggers provide identical output schemas, leading candidates to overlook that scheduled triggers lack user-provided fields like 'name'.
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 schedule trigger does not provide a 'name' field in its outputs, causing the expression to fail.
A scheduled trigger in Power Automate does not include a 'name' field in its outputs, whereas a manual trigger (e.g., Power Apps or button) typically does. When the flow runs on its daily 8 AM schedule, the expression referencing trigger outputs 'name' evaluates to empty, causing the subsequent actions to fail. This is a common mismatch between trigger types and expected output schemas.
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 action 'CreateRecord' has an invalid entity name 'Users'.
Why it's wrong here
If entity name were invalid, both manual and scheduled runs would fail.
- ✓
The schedule trigger does not provide a 'name' field in its outputs, causing the expression to fail.
Why this is correct
The schedule trigger does not generate a 'name' output, so the expression is empty.
- ✗
The flow is configured to run only on manual trigger, ignoring the schedule.
Why it's wrong here
The JSON shows both manual and schedule triggers are configured; schedule should work.
- ✗
The flow does not have permission to create records in Dataverse.
Why it's wrong here
Permission errors would occur on both manual and scheduled runs, not just scheduled; also error message would be different.
