PL-900 Demonstrate the capabilities of Power Apps Practice Question
A user wants to edit the fields displayed in a model-driven app form. Where should they go to customize the form?
⚠ Common exam trap
PL-900 often tests the misconception that model-driven app forms can be edited directly within the running app, confusing runtime editing with design-time customization.

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 maker portal
The Power Apps maker portal (make.powerapps.com) is the central environment for customizing model-driven apps, including editing forms. Within the maker portal, you can navigate to the specific app, open the form designer, and add, remove, or rearrange fields. This is the only option that provides the necessary design-time tools for form customization.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
From the app itself by selecting Edit
Why it's wrong here
Editing from within the running app only changes the current session's view, not the underlying form definition, so changes are not persisted for other users. The form designer in make.powerapps.com is the correct tool. In-app editing suits ad-hoc personal views, not schema customisation.
- ✓
Power Apps maker portal
Why this is correct
Form layout, field selection and control placement for model-driven apps are edited in the Power Apps maker portal, where the form designer exposes the table's fields. Editing records in the app itself changes data, not the form definition.
- ✗
Power Automate
Why it's wrong here
Power Automate orchestrates workflows and triggers, not form layout; it cannot add, remove or reposition fields on a model-driven form. It would be correct for automating a business process such as sending an approval email when a record is created, not for editing the form's field set.
- ✗
SharePoint list settings
Why it's wrong here
SharePoint list settings govern columns and views of a SharePoint list, not the form layout of a model-driven app. Editing a form's displayed fields is done in the app's form designer within the maker portal.
