Question 1

Which canvas app function retrieves all records from a Dataverse table where the 'Category' column is in a predefined list of values?

Accepted Answer

Filter(TableName, Category in ["A","B","C"])

Answer

The 'in' operator inside Filter() checks whether a column's value exists within a specified list, and this pattern is delegable for Dataverse.

Question 2

A canvas app component exposes an output property. How does the parent app read the component's output value?

Accepted Answer

Reference it as ComponentName.OutputPropertyName in a formula

Answer

Output properties defined in a canvas component are accessible from the host app by referencing ComponentInstanceName.PropertyName in any formula.

Question 3

In a model-driven app, which Dataverse feature automatically enforces field validation rules on the server side, independent of the form UI?

Accepted Answer

Business rules set to 'Entity' scope

Answer

Business rules scoped to 'Entity' execute on the server, enforcing validations and field requirements even when data is modified via API rather than the form.

Question 4

Which statement correctly describes the role of the 'notifyOutputChanged' callback in a PCF control?

Accepted Answer

It signals the framework that the control's output has changed so the bound property value can be updated

Answer

Calling notifyOutputChanged() tells the Power Apps framework to call getOutputs() on the control so the new value can propagate back to the bound Dataverse column.

Question 5

You need to display a loading spinner in a canvas app while a slow data operation runs. Which approach is most appropriate?

Accepted Answer

Use a variable to toggle a spinner control's Visible property during the operation

Answer

Setting a Boolean variable to true before the operation and false after controls the Visible property of a spinner image or HTML control, showing it only during loading.
