OutSystems, an Entity Identifier ...
Correct Answer:
C
Explanation
Web Blocks in OutSystems are reusable UI components that you can place on screens and within other Web Blocks. However, they cannot reference themselves directly or indirectly, which means recursive nesting is not allowed. This prevents circular dependencies and potential runtime issues. Understanding Web Block limitations is important when designing modular UI components.
Regarding Web Blocks in Outsystems, select to statement that is true.
Correct Answer:
C
Explanation
In OutSystems, the Registered role is a special built-in role that all authenticated users have automatically. When a screen is configured with the Registered role checked, any user who is logged in can access it, regardless of their specific assigned roles like OrdersAdmin. Michael's OrdersAdmin role grants him specific permissions, but the Registered role provides baseline access that applies to all authenticated users.
Attributes of static entities can be mandatory or not. A value is only required to be set if the attribute is mandatory.
Correct Answer:
A
Explanation
Static Entities in OutSystems let you define fixed sets of data with attributes. You can add attributes using basic data types like text and numbers. You can also create attributes that reference other static entities through identifier data types. This allows you to create relationships between static entities and model more complex data structures within your application.
Which of the following events is not available in Screens or Blocks?
Correct Answer:
B
Explanation
When you hide columns in an Aggregate, OutSystems still fetches those hidden columns from the database. The hiding only affects what you see in the preview and how the data displays in the UI. The hidden columns are still available if you need them later. This is important to understand because hidden columns do not improve performance since they are still retrieved from the database.
Consider that you want to change your application Header, with new fonts, colors and an icon. What is the best approach to accomplish that in Outsystems?
Correct Answer:
C
Explanation
The Destroy event fires when a screen is being removed from memory and cleaned up. It runs after the screen lifecycle ends, making it the right place to clean up resources that you added during the Ready event. Use it to remove JavaScript listeners and restore the DOM to its original state. The Ready event happens when the screen loads, so Destroy is the counterpart for cleanup operations.
In an Aggregate, the Sources section is used for...
Correct Answer:
C
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.

FAQ
Associate-Reactive-Developer Exam FAQ
Common questions about the exam itself
What background do I need before taking Associate Reactive Developer?
This exam targets developers new to OutSystems who can build simple reactive web and mobile applications. You should have basic development experience and understand how web applications work. The Reactive Developer Boot Camp is the recommended preparation path.
How hard is the Associate Reactive Developer exam compared to other OutSystems certifications?
The Associate Reactive Developer is the foundational certification in the OutSystems reactive track, so it focuses on fundamentals rather than advanced patterns. It emphasizes practical knowledge of screen lifecycle, data fetching, and basic logic flows rather than complex architecture decisions.
Which topic causes the most trouble for Associate Reactive Developer candidates?
Architecture and security topics tend to challenge candidates more because they require understanding how roles, permissions, and module dependencies affect the entire app. Spending extra time on how permissions control UI visibility and studying module producer-consumer patterns before the exam helps significantly.
How long should I study to prepare for Associate Reactive Developer?
Study time varies by your experience, but candidates typically spend two to four weeks preparing. Hands-on practice building small reactive apps and working through aggregates and data fetching scenarios during preparation correlates strongly with first-attempt success.
What happens on exam day for Associate Reactive Developer?
You have 120 minutes to answer all exam questions in a proctored environment. The exam tests practical knowledge through scenario-based questions rather than just definitions, so expect questions asking you to choose the right approach for real app development situations.
Can I retake the Associate Reactive Developer exam if I fail?
Yes, you can retake the exam, but check with your exam delivery provider about mandatory waiting periods between attempts and any other retake policies they enforce.
How long does the Associate Reactive Developer certification stay valid?
You should verify the certification validity period directly with OutSystems or through your exam registration, as renewal and expiration policies may have specific terms.
What job roles does Associate Reactive Developer certification prepare me for?
This certification qualifies you for junior reactive developer roles, contract positions, and team positions building OutSystems reactive web and mobile applications. It demonstrates you can handle foundational development tasks in a professional OutSystems environment.
How does Associate Reactive Developer relate to other OutSystems certifications?
Associate Reactive Developer is the entry point for the reactive track. After passing it, you can pursue more advanced certifications like Professional Reactive Developer, which covers complex patterns, performance optimization, and advanced architecture.
