PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A Power Automate flow processes incoming emails from a shared mailbox. Recently, some emails are being missed. You suspect the flow is hitting a service protection limit. Which action should you take to diagnose the issue?
⚠ Common exam trap
Test-takers frequently confuse 'skipped' status with 'failed' status, or assume that pausing/restarting the flow (Option D) is a valid diagnostic step, when in fact only run history provides the specific throttling evidence needed.

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
✓
Review the flow run history and look for 'skipped' status.
Flow run history in Power Automate explicitly records 'skipped' status for runs that were throttled due to service protection limits. By reviewing the run history and filtering for 'skipped' runs, you can directly confirm whether the flow is being rate-limited, which is the most likely cause of missed emails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use the 'Peek code' feature to review the flow definition.
Why it's wrong here
Peek code shows the JSON definition but not runtime throttling.
- ✗
Check the gateway status for the shared mailbox.
Why it's wrong here
Shared mailboxes do not require a gateway.
- ✓
Review the flow run history and look for 'skipped' status.
Why this is correct
Skipped runs indicate throttling or quota limits.
- ✗
Pause the flow and restart it.
Why it's wrong here
Pausing does not reveal throttling information.
