PL-900 Practice Question: Demonstrate the capabilities of Power Automate
A sales team at a manufacturing company wants a Power Automate cloud flow that automatically posts a message to a Microsoft Teams channel whenever a new record is added to a Microsoft Dataverse table named 'CustomerOrders'. The team does not want to write code. Which trigger should they use in the flow?
⚠ Common exam trap
The trap here is assuming any 'when something is created' trigger works, when each connector's trigger is bound to its own data source and cannot watch Dataverse tables.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
When a row is added, modified or deleted (Microsoft Dataverse)
Automating a Teams message from a new Dataverse record requires an event-based Dataverse trigger. The 'When a row is added, modified or deleted' trigger with the Added change type listens to the CustomerOrders table and starts the flow the moment a record is inserted, after which a Teams 'Post message' action can publish to the channel without any code.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
When an HTTP request is received
Why it's wrong here
This trigger exposes a manually invoked HTTPS endpoint and only runs when an external caller posts to that URL. Nothing in the scenario makes an inbound HTTP call when a Dataverse row is created, so the flow would never start automatically from the CustomerOrders table event.
- ✗
When a file is created (properties only)
Why it's wrong here
This SharePoint trigger fires when a document is uploaded to a document library. CustomerOrders is a Dataverse table, not a SharePoint library, so this trigger watches the wrong data source entirely and would never respond to new order rows.
- ✗
Recurrence
Why it's wrong here
Recurrence starts a flow on a fixed schedule, such as every five minutes, rather than in response to a row being created. Although a scheduled poll could eventually detect new records, it is not event-driven, adds latency, and requires extra query actions, so it does not meet the requirement for automatic posting on creation.
- ✓
When a row is added, modified or deleted (Microsoft Dataverse)
Why this is correct
The Microsoft Dataverse connector provides the 'When a row is added, modified or deleted' trigger, which fires on create, update, or delete events for a chosen table. Selecting the 'Added' change type and the CustomerOrders table gives the exact no-code trigger needed to start the flow when a new order record appears.
