PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A company uses Power Automate to process expense reports. The flow must run only on weekdays and must not run more than once per hour. The flow is currently triggered manually. Which trigger should be used to meet these requirements?
⚠ Common exam trap
The trap here is thinking that any trigger that runs on a schedule will work, but only the Recurrence trigger provides the granular control over days and intervals needed.

Correct answer & explanation
✓
Recurrence
The Recurrence trigger is designed for scheduled execution. It allows configuration of interval and frequency, such as every hour, and selection of specific days of the week. In this scenario, setting the recurrence to run hourly on weekdays only meets both the timing and frequency constraints. Other triggers are event-based and cannot enforce the required schedule.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually trigger a flow
Why it's wrong here
A manual trigger requires a user to initiate the flow, so it cannot run automatically on a schedule. It also provides no mechanism to enforce weekday-only execution or hourly limits. The scenario explicitly states the flow must run on weekdays and not exceed hourly frequency, which a manual trigger cannot guarantee.
- ✗
When an item is created in SharePoint
Why it's wrong here
This trigger runs when a new item is added to a SharePoint list, which is event-driven rather than schedule-based. It cannot restrict execution to weekdays or limit frequency to once per hour. If multiple items are created, the flow would run multiple times, violating the frequency constraint. Thus, it does not satisfy the requirements.
- ✗
When a file is created (properties only) in SharePoint
Why it's wrong here
This trigger fires when a file is created in a SharePoint library, which does not enforce a weekday-only or hourly schedule. It would run whenever a file is added, potentially outside business hours and more frequently than once per hour. The requirement is for time-based execution, not file-based, so this trigger is inappropriate.
- ✓
Recurrence
Why this is correct
The Recurrence trigger allows you to schedule a flow to run at a specific interval, such as every hour, and you can configure it to run only on weekdays by selecting specific days in the schedule. This directly meets both conditions: running only on weekdays and not more than once per hour. It is the standard trigger for time-based automation in Power Automate.
