PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A non-profit organization uses Power Automate to automatically send thank-you emails to donors after they make a donation through a third-party payment gateway. The flow is triggered when a new row is added to a Dataverse table named 'Donations'. The flow then uses the 'Send an email (V2)' action to send the email. The flow has been working for months, but today donors started complaining that they are not receiving the thank-you emails. The flow run history shows that the flow runs successfully and the 'Send an email' action shows 'Succeeded'. What is the most likely cause of the issue?
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 email account used in the 'Send an email' action has been deactivated or its credentials have changed
The 'Send an email' action in Power Automate requires a connection to an email server; if the connection uses a shared mailbox or a service account, and that mailbox's credentials expire or the mailbox is deactivated, the flow will appear to succeed but the email will not be delivered. Option B is incorrect because if the email goes to spam, the flow would still show success. Option C is incorrect because the trigger is working. Option D is incorrect because the donor table is populated, so the flow runs.
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 email account used in the 'Send an email' action has been deactivated or its credentials have changed
Why this is correct
If the sending mailbox is disabled, emails are not sent but the action may succeed.
- ✗
The flow is not processing new donor records
Why it's wrong here
The flow runs successfully, so it is processing records.
- ✗
The donors' email addresses are invalid
Why it's wrong here
Invalid addresses would cause the action to fail, not succeed.
- ✗
The Dataverse table trigger is not firing
Why it's wrong here
The flow runs successfully, so the trigger is firing.
