PL-900 Demonstrate the capabilities of Power Apps Practice Question
A sales team needs an app to track customer interactions. The app should display a list of accounts, and when an account is selected, show related opportunities and contacts. Which type of app is best suited?
⚠ Common exam trap
PL-900 often tests the distinction between canvas apps (for custom UI and task-specific apps) and model-driven apps (for data-centric, relationship-based apps), so candidates may incorrectly choose canvas apps when the requirement emphasizes automatic relationship navigation.
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
✓
Model-driven app
Model-driven apps are ideal for complex, data-centric scenarios where the app is built on top of Microsoft Dataverse. They automatically generate a UI based on the data model, including relationships between entities like Account, Opportunity, and Contact. When an account is selected, the app can display related records through built-in navigation and subgrids, exactly as required. This makes model-driven apps the best fit for tracking customer interactions with linked entities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Canvas app
Why it's wrong here
A canvas app gives the developer a blank canvas with no automatic record-to-related-record navigation, so the account, opportunity and contact relationship must be built manually. It is tempting for its design freedom, and it would suit a highly customised interface rather than model-driven relationship views.
- ✗
Power BI dashboard
Why it's wrong here
A Power BI dashboard renders aggregated visuals for analysis, not interactive record navigation between accounts, opportunities and contacts. It is tempting because Power BI connects to Dataverse and displays account data, but it would be correct when the requirement is reporting and insight rather than transactional record browsing.
- ✗
Chatbot in Power Virtual Agents
Why it's wrong here
A Power Virtual Agents chatbot handles conversational question-and-answer flows, not a relational list-to-detail interface showing related records. It is tempting because chatbots surface Dataverse data conversationally, but it would be correct when users need to query information through natural-language dialogue rather than navigate linked tables.
- ✓
Model-driven app
Why this is correct
Model-driven apps generate UI directly from the Dataverse data model, so defining relationships between accounts, opportunities and contacts produces the list-and-related-records navigation automatically, with no manual screen wiring. This satisfies the requirement to show related opportunities and contacts when an account is selected.
