PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A company wants to build a custom app that allows field technicians to view and update work orders on their mobile devices, with data stored in Dataverse. Which approach minimizes development effort?
⚠ Common exam trap
PL-900 often tests the distinction between canvas and model-driven apps — candidates must recognize that canvas apps minimize effort for custom mobile UIs, while model-driven apps are better for complex, data-centric processes.
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
✓
Create a canvas app in Power Apps
Canvas apps in Power Apps are designed for rapid, low-code development with drag-and-drop UI and direct Dataverse connectivity, making them the fastest path to a mobile-friendly work order app. They can be published to Power Apps mobile and run on iOS and Android without native development.
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 canvas app in Power Apps
Why this is correct
Canvas apps provide drag-and-drop screens and native Dataverse connectors, so technicians get mobile work-order views and updates with minimal coding. This directly satisfies the constraint of minimising development effort, unlike model-driven or custom-code approaches that demand more configuration or developer skill.
- ✗
Use Power Automate to generate a mobile app
Why it's wrong here
Power Automate orchestrates flows and approvals; it cannot render mobile forms or write interactive Dataverse records. It is tempting because it connects to Dataverse and triggers on events, but it is the right choice for automating background processes, not for building a technician-facing app.
- ✗
Build a custom iOS app using Swift and Xcode
Why it's wrong here
Native Swift development requires building screens, Dataverse connectors and offline sync from scratch, so it cannot minimise effort. It is tempting because Swift suits bespoke, performance-critical iOS features, but Power Apps offers prebuilt Dataverse integration and mobile rendering without coding.
- ✗
Create a model-driven app in Power Apps
Why it's wrong here
Model-driven apps generate form and view interfaces from the Dataverse data model, but they render poorly on phones and demand more configuration than a canvas app. They are tempting because they sit directly on Dataverse, and suit complex desktop line-of-business processes rather than simple mobile work-order updates.
