Read the first 7 Create Power Apps flashcards as text

  1. A developer needs to pass a large dataset between canvas app screens without re-querying the data source. What is the best approach?

    Answer: Store the data in a global variable using Set() and access it on the next screen

    Global variables created with Set() are accessible across all screens in a canvas app and persist for the session without additional data source calls.

  2. Which Power Apps feature allows a developer to test a canvas app's behavior with different user roles without switching accounts?

    Answer: Security role preview in canvas app authoring

    Canvas app authoring supports a security role preview that simulates how the app behaves for users assigned to specific Dataverse security roles.

  3. A developer is building a model-driven app and needs to display a custom visualization of aggregated data. Which approach is most appropriate?

    Answer: Add a Power BI embedded report to a model-driven app dashboard

    Power BI reports can be embedded in model-driven app dashboards, providing rich, interactive aggregated data visualizations.

  4. When implementing a PCF (Power Apps Component Framework) field control, which interface must the component class implement?

    Answer: ComponentFramework.StandardControl

    All PCF controls must implement the ComponentFramework.StandardControl generic interface, typed with the component's IInputs and IOutputs interfaces.

  5. A canvas app developer needs to handle errors returned by the Patch function when writing to Dataverse. Which function should they use?

    Answer: IfError(Patch(...), Notify(FirstError.Message, NotificationType.Error))

    IfError wraps any formula including Patch and provides access to FirstError.Message, allowing developers to display or log error details.

  6. A developer needs to create an environment variable in a Power Apps solution to store a configuration value that differs between development and production. Where is this configured?

    Answer: As an environment variable definition and value within the solution

    Environment variables are added as components within a solution, with separate definition and value records allowing different values per environment.

  7. When a canvas app connects to an on-premises SQL Server database, which infrastructure component is required?

    Answer: On-premises data gateway

    The on-premises data gateway acts as a secure bridge between Power Apps cloud services and on-premises data sources like SQL Server.
