PL-900 Practice Question: Demonstrate the capabilities of Microsoft Copilot Studio
A support team uses a copilot built with Microsoft Copilot Studio to handle password reset requests. The copilot must collect the user's employee ID and then call an existing Power Automate cloud flow that performs the reset. The maker wants the copilot to pass the employee ID to the flow and return the result to the user. What should the maker configure in the copilot topic?
⚠ Common exam trap
The trap here is assuming that any node that can call an external endpoint, such as an HTTP request, is equivalent to the built-in call an action integration for Power Automate flows.

Correct answer & explanation
✓
Add a question node for the employee ID, then add a call an action node that invokes the cloud flow and maps the employee ID variable to the flow input.
The maker should use a question node to collect the employee ID and a call an action node to invoke the Power Automate cloud flow, mapping the variable to the flow input. This is the supported pattern for passing data from a copilot to a flow and returning results. Condition nodes, HTTP requests, and generative answers do not provide the same integrated flow invocation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add a condition node that checks whether the employee ID matches a pattern, then publish the copilot to Microsoft Teams.
Why it's wrong here
A condition node can validate the format of the employee ID, but it does not invoke the Power Automate flow or pass data to it. Publishing to Teams only makes the copilot available to users. Neither action performs the password reset or returns the flow result, so the integration requirement is not met.
- ✗
Add a generative answers node that uses the employee ID as a knowledge source and lets the flow run automatically.
Why it's wrong here
Generative answers nodes are for answering questions from knowledge sources, not for invoking flows. They do not pass variables to a Power Automate flow or trigger a reset action. Using this node would not perform the password reset or return the flow's result to the user.
- ✓
Add a question node for the employee ID, then add a call an action node that invokes the cloud flow and maps the employee ID variable to the flow input.
Why this is correct
A question node captures the employee ID into a variable. The call an action node in Copilot Studio can invoke a Power Automate cloud flow and map that variable to the flow's input parameter. This allows the copilot to pass the employee ID, run the reset, and use the flow's output in the conversation.
- ✗
Add an HTTP request node that calls the Power Automate flow's trigger URL directly with the employee ID.
Why it's wrong here
An HTTP request node can call an endpoint, but Power Automate flows are more reliably invoked from Copilot Studio through the call an action node, which handles authentication and parameter mapping. Using a raw HTTP request adds complexity and may fail due to authentication or schema mismatches. It is not the recommended way to call a cloud flow from a copilot topic.
