PL-900 Practice Question: Describe the business value of Microsoft Power Platform
Exhibit
Refer to the exhibit.
```json
{
"triggers": [
{
"type": "When a file is created",
"inputs": {
"location": "SharePoint",
"folder": "/documents/invoices"
}
}
],
"actions": [
{
"type": "Send an email",
"inputs": {
"to": "finance@contoso.com",
"subject": "New invoice uploaded",
"body": "Invoice @{triggerOutputs()?['headers/Content-Disposition']} has been uploaded."
}
}
]
}
```You are reviewing a Power Automate flow definition. The flow should send an email when a new invoice file is added to a SharePoint folder. However, the flow is not triggering. What is the most likely cause?
⚠ Common exam trap
Candidates often assume the trigger type is wrong (option D) because they confuse 'created or modified' with 'created only', but the real issue is typically a misconfigured folder path or permissions, not the trigger selection.
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 folder path '/documents/invoices' is incorrect or the flow lacks permissions.
The most likely cause is that the folder path '/documents/invoices' is incorrect or the flow lacks permissions. Power Automate triggers for SharePoint require exact folder paths and appropriate access rights to monitor file additions. If the path is misspelled, uses a relative path instead of a server-relative path, or the service account does not have read permissions on the folder, the trigger will not fire.
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 folder path '/documents/invoices' is incorrect or the flow lacks permissions.
Why this is correct
Incorrect folder path or permissions can prevent triggering.
- ✗
The email action uses an incorrect dynamic expression.
Why it's wrong here
The expression is valid for retrieving the file name.
- ✗
The flow needs a 'Get file content' action before sending email.
Why it's wrong here
Sending an email with the file name does not require file content.
- ✗
The SharePoint trigger requires a 'When a file is created or modified' trigger instead.
Why it's wrong here
'When a file is created' is valid for new files.
