Question 1 Domain 1 Reactive Apps in OutSystems

Consider a Form with a Save button with the Built-in Validations property set to Yes. When a user clicks on the Save button, some validations over the data submitted to the Form are automatically performed by OutSystems by default. Which validations are those?

Correct Answer C
Explanation The OutSystems debugger provides specific commands for controlling execution like Continue, Step Over, Step Into, and Step Out. Restart Debugging is not an available command in the debugger interface. The other options represent actual debugger commands that allow you to control how your code executes during debugging sessions.

Question 2 Domain 2 Fetching Data

Which of the following is the correct order of occurrence of events in a Screen?

Correct Answer C
Explanation List.Current is a function used within aggregates and loops to reference the current record being processed. It always returns the first record in the list when called, not a record at any arbitrary position. If you need to access records at specific positions, you would use List.Index or similar functions instead.

Question 3 Domain 4 UI Design

Which of the following is not an Entity Action of the Customer Entity?

Correct Answer D
Explanation Expressions on screens are evaluated during the screen build process, not at runtime. The value is calculated once when the screen is built and then displayed as static content. This is different from actions or dynamic content that recalculates based on user interactions or data changes. Understanding this timing is important for knowing when expressions refresh.

Question 4 Domain 4 UI Design

Screen Actions can also call Server Actions.

Correct Answer A
Explanation Placeholders function as named containers within blocks that reserve space in the user interface. When you instantiate a block that contains a placeholder, the placeholder gets allocated with the content you provide. This design pattern allows blocks to be flexible and reusable across different screens while maintaining a defined layout structure.

Question 5 Domain 1 Reactive Apps in OutSystems

The SQL Query only allows executing SELECT statements

Correct Answer B
Explanation Breakpoints in OutSystems can be placed in actions only, whether those actions run on the client side or server side. You cannot place breakpoints directly on the screen itself or in other elements. This restriction helps focus debugging efforts on the logic layers where your application's behavior is actually controlled and where state changes happen.

Question 6 Domain 2 Fetching Data

When columns are hidden in an Aggregate ...

Correct Answer B
Explanation Ajax Refresh works by updating a specific widget without reloading the entire screen. For this to happen, the widget needs a Name property so the system knows which widget to refresh. The Screen Action must also be executed with Ajax Submit enabled, which tells OutSystems to use the Ajax refresh mechanism instead of a traditional form submission. Without the widget name, the system cannot identify the target. Without Ajax Submit, the action performs a regular refresh instead. Both conditions are required for Ajax Refresh to function correctly.

Question 7 Domain 3 Logic

Email, Phone number is Basic data type?

Correct Answer A
