PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A retail company uses Power Apps to manage inventory. The app allows store managers to scan barcodes and update stock levels in real time. The company wants to extend this capability to suppliers so they can view stock levels but not modify them. Which Power Platform component should be used to create the supplier-facing interface?
⚠ Common exam trap
Many exam-takers confuse a canvas app’s ability to share with external users (via guest access) with a purpose-built external-facing portal, forgetting that canvas apps require licensing and are not designed for anonymous or lightly authenticated external access without complex Azure AD setup.

Correct answer & explanation
✓
Power Apps portals
Power Apps portals (now part of Power Pages) allow external users, such as suppliers, to access data through a low-code, authenticated website without requiring a Power Apps license or internal network access. This enables suppliers to view stock levels via a browser-based interface while preventing any modification, as permissions can be set to read-only. Canvas apps, by contrast, are designed for internal users and require a license or guest access in Azure AD, making portals the correct choice for external, unauthenticated or lightly authenticated scenarios.
