Pass the OutSystems Reactive Web Developer Associate-Reactive-Developer Questions and answers with ValidTests

A Reactive Web App is a cross-device app.

The code generated by OutSystems results in a single-page application.

A developer builds the Reactive Web App in Service Studio.

Data requests are executed synchronously.

End-users can only be created programmatically, using Actions from the Users application.

There are three built-in roles in OutSystems: Anonymous, AppUser and Registered.

All users, with or without a login, have automatically the Registered Role.

By default, end-users are managed in the built-in Users application.

Go to the Users application and associate the Screen to a specific role.

Use the CheckRole Action.

In the Screen Properties, untick roles to restrict their access.

We don't. Only users with a username and password can access.

When the web block is in one screen, the parent screen is required to have a screen action to handle the event of the child web block, but the case is in another web block.

When the web block is in a web block, the parent web block is required to have a screen action to handle the event of the child web block, but the case is in another screen.

When the web block is in one screen or another web block, the parent screen or web block is required to have a screen action to handle the event of the child web block.

When the web block is in one screen or another web block, the parent screen or web block is not required to take action to handle the event of the child web block.

They cease to be part of output of the Aggregate

They are still part of output of the Aggregate

They are the only columns on the output of Aggregate

It's because they are empty on the database

The output of the Aggregate will contain all attributes from the Source Entities plus the aggregation columns.

The output of the Aggregate will not include the columns at grey.

We can apply the following functions on attributes of integer data type: sum, max, min, count and average.

We can apply multiple aggregation functions inside an Aggregate.

In the producer, set the Entry Module property to the consumer module.

We need to also start the debugger on the producer module.

Nothing, just leave Service Studio open.

We just need to set breakpoints in the producer module. The execution will stop on its breakpoints automatically.

The On Initialize event is triggered before the Screen or Block is rendered and before fetching any data.

The On Initialize event is triggered after the Screen or Block has been rendered, so you can use it to manipulate its structure.

The On Initialize event is triggered after an Aggregate finishes fetching data and can be used to act upon the retrieved data before it's used in the Screen.

The On Initialize event is triggered after the input parameter of a Block changes.

Manipulate the DOM.

Set the default value of a Local Variable.

Act on data returned by a Data Action.

Retrieve data from the server database.

To define the order of its output records.

To define the Entities we want to get records from.

To define values for testing the preview of the Aggregate's output.

To set the conditions to get specific records, not all the records.
