PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
A retail company uses Microsoft Copilot Studio to build an internal copilot that helps store managers reorder low-stock items. The reorder process is implemented as a Power Automate cloud flow named 'Submit Reorder'. The copilot must collect an item number and quantity from the manager and then run the flow. Which Copilot Studio action should you add to the topic to run the flow?
⚠ Common exam trap
The trap here is assuming that enabling generative responses or creating a similarly named entity will cause the flow to run, when the flow must be explicitly invoked as an action.
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
✓
Call an action, selecting the 'Submit Reorder' cloud flow.
Power Automate cloud flows are surfaced in Copilot Studio as actions, and a topic can invoke them with a call an action step. This lets the copilot pass collected inputs such as item number and quantity into the flow and return results to the conversation. Redirects, entities, and generative response settings do not execute cloud flows.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Call an action, selecting the 'Submit Reorder' cloud flow.
Why this is correct
Copilot Studio exposes Power Automate cloud flows as actions that can be invoked from within a topic. Selecting the 'Submit Reorder' flow as a call an action step runs the flow during the conversation and returns its outputs to the copilot. Inputs collected earlier, such as item number and quantity, can be mapped into the flow's parameters, making this the correct way to execute the reorder process.
- ✗
Enable the 'Generate responses' setting so the copilot can infer when to run the flow.
Why it's wrong here
Generative responses control how the copilot composes natural language answers from knowledge sources; they do not trigger Power Automate flows. The copilot will not automatically discover and run a cloud flow based on this setting. Explicitly invoking the flow as an action is required, so relying on response generation would leave the reorder process disconnected from the conversation.
- ✗
Create a new entity named 'Submit Reorder' and map it to the item number variable.
Why it's wrong here
Entities extract or validate values from user input; they do not execute external processes. Naming an entity after the flow does not create any connection to Power Automate, so the reorder would never run. This confuses the data-extraction role of entities with the process-execution role of actions, and it would leave the scenario unfulfilled.
- ✗
Add a Redirect node that sends the user to the Power Automate portal to run the flow manually.
Why it's wrong here
A redirect sends the user away from the copilot, breaking the conversational experience and requiring the manager to run the flow themselves. The requirement is for the copilot to execute the process after collecting inputs, not to hand the task back to the user. Redirects are used for web links or handoffs, not for invoking a cloud flow with conversation data.
