Assoc Reactive Web

The DoLogin Action...

• Is a Server Action that will return a cached value if the applicaiton is offline.

• Is a Server Action that will run only when the applicaiton is online.

• Is a Client Action that will be called when the end-user provides a username and password.

• Is called on every screen at the OnInitialize event.

A Data Actions is:

• A Server Action that fetches and processes data from a Web Service.

• A specific type of Action with an OnAfterFetch event, used to fetch data from different sources.

• Any Server Action that fetches data from different sources, including Database, Local Storage and Web Services.

• Any Action with an OnAfterFetch event, used to fetch data from the Database and Local Storage.

Using the Debugger, what is one of the possible solution if you want to analyze an exception flow in your code when it raises on browser?

• Add a breakpoint on the Raise Exception node present in your code flow, before you start the Debugger process. Then on browser execture the procedure that will raise the exception. After the code stops, inspect the Exception flow on Service Studio.

• Add a breakpoint on the Start Node of your Screen Action responsible for executing the code that will raise that specific exception before you start the Debugger. Then test your app on browser, once the code stops working go to the Service Studio and inspect your code flow until it reaches the Exception Flow.

• Add a breakpint directly on Screen Action repsonsible for executing the code that will raise the specific exception before you start the Debugger. then test your app on browser once the code stops, go through your code flow inside Service Studio until you reach the Exception flow.

• All options are valid.

If a screen is restricted to registered users..

• The restriction is enforced client-side.

• The restriction is enforced client-side but the application needs to be online.

• You need custom logic to enforce it.

• That restriction is enforced server-side.

If a user doesn't have the necessary Role to access a screen...

• a Security Exception is raised and the On Exception action will redirect the user to another screen.

• a Security Exception is raised and the On Exception action will show a pop-up with an error message.

• a Security Exception is raised and the Application Server returns to the Browser and HTTP 400 error (not authorized).

• a Security Exception is raised and the Application Server retruns to the Browser an HTTP 401 error (forbidden).

Given the system's User entity and a Photo entity as depicted in the image below, what is the best way to model that a User may have a unique profile photo?

• Create a Profile Entity with attributes PhotoId and UserId of types Photo Identifier and User Identifier respectively.

• Change the Photo Entity's Id attribute to be of type User Identifier.

• Add to the User Entity a PhotoId attribute of type Photo Identifier.

• Add to the Photo Entity a UserId attrbiture of type User Identifier.

Fetching data from the database to show on a screen list...

• If done with an Aggregate on the screen is asynchronous.

• If done in a Client Action is synchronous

• Is always asynchronous and must be done with a Data Action.

• Is always synchronous, and must be done in an Aggregate inside a Data Action.

Which of the following is a possible reason for this error to be displayed to the user?

• The Developer defined the GenderId as a Mandatory field on the Geneder Dropdown widget, but the End-Use forgot to select one valid Gender when he save the Trainee Record on the database.

• The End-User is trying to add an existing Trainee on the Gender List, without selecting the Trainee name and before the Save button is clicked. Thus, the Trainee Identifier is sent to the Database as NULL.

• The Entity trainee has a GenderId attribute, which is a Foreign Key to the Entity Gender. The GenderId attribute is also marked as mandatory on the database. And the End-User is trying to save a Trainee without selecting a valid Gender on the Form.

• The Entity trainee has a Unique Index with two of its attributes. Trainee Identifier and Gender identifier. If an End-User tries to Save a duplicate record of the Trainee with the same Gender, the error will be displayed.

An End-User logged in to your Reactive application is trying to access a Screen, but the user doesn't have the required role permissions checked on that Screen. What will happen in this situation, taking into consideration the OnException flow image below?

• If the user's Session didn't timeout, the user will be redirected to another screen.

• First, the user will see a generic Exception Message (from AllExceptions). Then, the user need to click on the button to try the communications between the app and the server, and only if the communication test runs with success, the Security Exceptions will be performed.

• Thee application will close, and the user account will be blocked.

• The user will be redirected to the Users Applications here she/he can assign the role to her/his account.

After you create an action in one module to be consumed by other modules, what's required to guarantee that you will not have any issues finding the action, when managing the dependencies in the consumer modules?

• Publish the Producer module with the new Action, before opening the Management Dependencies on the Consumer module.

• If the output of the Action is a Structure that is defined within the same module that the Action, that Structure needs to be Public as well.

• All the options are valid.

• The new Action must be set as Public on the Producer module, beofre consumming it in other modules.
