PL-900 Demonstrate the capabilities of Power Apps Practice Question
A manager wants to create a Power App that shows a list of customer orders with the ability to drill into each order's details. Which approach is most efficient?
⚠ Common exam trap
PL-900 often tests the misconception that a data table control can handle drill-down navigation, when in fact it is display-only and lacks selection context for detail screens.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a gallery to list orders and navigate to a detail screen on selection
The gallery control is the standard Power Apps pattern for displaying a list of records from a data source, and its OnSelect property can navigate to a detail screen while passing the selected record's context. This approach is efficient because it uses a single reusable detail screen that dynamically displays the selected order, avoiding duplication. It also leverages built-in delegation and performance optimizations for large datasets when configured correctly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a data table connected directly to the data source
Why it's wrong here
A data table bound directly to the source displays records but provides no built-in detail view or navigation to a selected order's fields, so drill-down must be hand-built. Data tables suit read-only dashboards; a gallery with a detail screen is the pattern for master-detail drill-down.
- ✓
Use a gallery to list orders and navigate to a detail screen on selection
Why this is correct
A gallery bound to the orders data source renders the list, and its OnSelect property can navigate to a detail screen passing the selected record's context. This single-screen-plus-detail pattern avoids duplicating controls per order, meeting the drill-down requirement efficiently.
- ✗
Use a single form with navigation buttons to move between orders
Why it's wrong here
Navigation buttons on a single form require manual screen switching and cannot render a scrollable order list, so drilling into details means building each transition by hand. It is tempting because forms suit single-record editing, and this would be correct for a kiosk-style wizard capturing one order at a time.
- ✗
Export the data to Excel and use Power Apps to display the Excel file
Why it's wrong here
Excel is not a dynamic data source for real-time browsing
