Start Demonstrate the capabilities of Power Apps PracticeA retail company uses Power Apps to build a mobile app for store managers to approve discount requests. The app must work offline and sync when connected. Which type of app should the developer choose?
Explanation: Canvas apps are the correct choice because they support offline capability by leveraging the Power Apps offline sync feature, which allows data to be cached locally on the device and synchronized with the data source (e.g., Dataverse or SharePoint) when connectivity is restored. This makes them ideal for mobile scenarios like store managers approving discount requests in areas with intermittent connectivity.
A healthcare organization needs a Power Apps app to track patient visit data. The data must be stored in Microsoft Dataverse, and the app should automatically generate a timeline of visits for each patient. Which app type is most suitable?
Explanation: A model-driven app is the most suitable choice because it is designed for complex, data-centric business applications that require rich relational data modeling, automated business logic, and built-in timeline controls. Dataverse provides the underlying relational storage, and model-driven apps natively support timeline components that automatically aggregate and display patient visit records in chronological order without custom development.
A company has a canvas app that uses a SharePoint list as its data source. The app works fine for most users but a few users report that they cannot submit new items. They receive a generic 'Access denied' error. What is the most likely cause?
Explanation: The 'Access denied' error when submitting new items in a canvas app connected to a SharePoint list indicates that the user lacks write permissions on the underlying data source. Even though the app is shared with the user, the SharePoint list itself enforces its own permission model. Without Contribute or Edit permissions on the list, the user cannot create new items, resulting in the generic access denied error.
A company wants to build a Power Apps app that uses a SQL Server database as its data source and requires complex business logic validation before saving data. Which type of app should they use?
Explanation: Canvas apps are the correct choice because they allow full control over the user interface and can incorporate complex business logic validation using Power Fx formulas before data is written to the SQL Server database. Unlike model-driven apps, which rely on predefined forms and server-side business rules, canvas apps enable custom validation logic directly in the app's formulas, such as checking multiple field conditions or calling custom connectors.
A company has a model-driven app with a custom table 'Issue' that has a choice column 'Status' with values: New, In Progress, Resolved, Closed. The app uses a business rule to set 'Resolved By' (lookup to User) when status changes to Resolved. Users report that the 'Resolved By' field is not being populated. What is the most likely cause?
Explanation: Business rules in model-driven apps can be scoped to either the entity (all forms) or a specific form. If the rule is scoped to a particular form (e.g., the main form) but the status change occurs via a quick create form, the rule will not trigger. This is the most likely cause because users report the field is not populated, indicating the rule is not firing in the context where the status is being changed.
