PL-900 Practice Question: Demonstrate the capabilities of Power Automate
You are a business analyst at a manufacturing company. You need to create a flow that automatically saves email attachments from a specific sender to a SharePoint document library. The flow should trigger when a new email arrives in your mailbox. What should you use?
⚠ Common exam trap
PL-900 often tests the distinction between flow types — the trap is confusing 'automated' (event-triggered) with 'instant' (manually triggered) or with business process flows, which are UI constructs, not automation engines.

Correct answer & explanation
✓
Create an automated cloud flow
An automated cloud flow in Power Automate is triggered by an event — such as 'When a new email arrives' — and runs without user interaction, which is exactly what's needed to save attachments to SharePoint. It uses the Outlook and SharePoint connectors natively. This is the canonical Power Automate pattern for email-driven document routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a business process flow
Why it's wrong here
Business process flows guide users through defined stages of a business process, such as order fulfilment or case handling, and cannot react to inbound email events or move files. They are tempting because they also live in Power Automate, but they require a user-driven process with stages, not an automated trigger-action sequence.
- ✗
Create a desktop flow
Why it's wrong here
A desktop flow automates interactions with a graphical user interface, so it cannot react to an inbound email event or write directly to a SharePoint library. It is tempting because desktop flows suit attended, UI-driven tasks such as entering data into a legacy manufacturing application that exposes no API or connector.
- ✗
Create an approval flow
Why it's wrong here
An approval flow routes a request to designated approvers and records their decision; it cannot watch an inbox or write attachments into a SharePoint library. The required trigger is 'When a new email arrives', paired with a SharePoint 'Create file' action. Approval flows suit document sign-off or leave-request scenarios, not automated attachment capture.
- ✓
Create an automated cloud flow
Why this is correct
An automated cloud flow is triggered by an event rather than manual start, so the 'when a new email arrives' trigger fires on each incoming message. This satisfies the requirement for automatic execution, then a SharePoint action saves the attachment to the document library.
