PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A small business owner wants to create a customer loyalty program. They want customers to earn points for purchases and redeem them for discounts. The owner has no coding experience and a limited budget. They need a mobile-friendly app for customers to check points and a backend to manage points and redemptions. What should they use?
⚠ Common exam trap
PL-900 often tests the confusion between Power BI (analytics) and Power Apps (app development), or between Power Pages (websites) and Power Apps (mobile apps), leading candidates to choose incorrect components.
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
✓
Power Apps, Power Automate, and Dataverse
Power Apps allows building a mobile-friendly app without coding, Power Automate handles workflow automation for points and redemptions, and Dataverse provides a secure and scalable backend data store. This combination meets the requirements of no coding, limited budget, and mobile app with backend management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Power BI, Power Automate, and Dataverse
Why it's wrong here
Power BI provides reporting and dashboards, Power Automate orchestrates flows, and Dataverse stores data, but this trio supplies no application UI or mobile client for customers to view points and redeem discounts without coding. It is tempting because all three are low-code Power Platform components, and it would be correct when the requirement is analytics and automated data processes rather than a customer-facing app.
- ✓
Power Apps, Power Automate, and Dataverse
Why this is correct
Power Apps delivers the mobile-friendly customer interface with no coding, Power Automate handles points and redemption logic, and Dataverse stores the loyalty data relationally. Together they satisfy the no-code, low-budget constraint whilst providing both app and backend.
- ✗
Power Apps, AI Builder, and Dataverse
Why it's wrong here
AI Builder adds prebuilt AI models for prediction and form processing, not the points ledger or redemption workflow this loyalty scheme needs. The owner needs Power Apps plus Dataverse alone; AI Builder would be the right choice for scenarios requiring document extraction or prediction from data.
- ✗
Power Pages, Power Automate, and SharePoint
Why it's wrong here
Power Pages requires a portal licence and custom development to build a mobile app, which exceeds the limited budget and no-coding constraint; the correct low-code alternative would be a Power Apps canvas app with a Dataverse backend. This option is tempting because Power Automate and SharePoint together can handle workflow automation and data storage, making it a viable choice for internal process automation where a public-facing mobile app is not required.
