OutSystems - Becoming a
Reactive Web Developer

A Block can be used... A. Only inside other Screens. B. Inside
Screens and Blocks, including itself. C. Inside Screens and Blocks,
except on itself. D. Only inside other Blocks. - C. A developer should
favor using a Structure instead of the Entity in the output of a
SELECT SQL Query. Do you agree with this statement? A. Yes,
because queries become easier to maintain. B. Yes, because queries
will retrieve fewer Attributes and less data. C. No, since it is exactly
the same. D. No, it is preferable to use the Entity instead of the
Structure. - B. Attributes of static entities can be mandatory or
not. A value is only required to be set if the attribute is mandatory.
A. True B. False - A. Business concepts that need to be stored and
accessed in our applications should be modeled as... A. Entities. B.
Entity diagrams. C. Entity relationships. D. Database tables. - A.
Client Actions and Server Actions can have the following variables:
A. Input and Output Parameters, but no Local variables. B. Input
Parameters and Local Variables, but no Output Parameters. C.
Input and Output Parameters, as well as Local Variables. D. Output
Parameters and Local Variables, but no Input Parameters. - C.
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?
A. Check if the mandatory fields are filled in. B. Check if the
mandatory fields are filled in and if the non-mandatory fields,
that are later used in the logic, are also filled in. C. Check if the
mandatory fields are filled in and if the data submitted by the user

,matches the data type expected in the input fields. D. Check if the
mandatory fields are filled in and if the data submitted by the user
matches the data type of the Form's data source. - C. Consider a
Screen that contains a Form to collect Customer data. The Form
has a Save Button with the On Click Destination set to a
SaveOnClick Action, which sends the data to the server to store it
in the database. What is the best way to make sure that we do not
send the data to the server when the mandatory Customer data
fields have not been filled in? A. Just set the Built-in validations of
the Save button to Yes. B. Perform custom validations for all inputs.
If one fails, set the Valid property of the Form to False. C. Set the
Built-in validations of the Save button to Yes and check if the
Form's Valid property is True. D. Set the Built-in validations of the
Save button to Yes and add an Exception Handler flow to handle
invalid inputs. - C. Consider an Aggregate with a "With or Without"
join between two entities. What is the expected output of the
Aggregate? A. All records from both Entities (FULL OUTER JOIN).
B. Only records where there is a match between the two Entities
(INNER JOIN). C. All records from the left entity even if there is no
match in the right entity (LEFT JOIN). D. All records from the
right entity even if there is no match in the left entity (RIGHT
JOIN). - C. Consider an Aggregate with the Fetch property set to
Only On Demand. When does that Aggregate run? A. Automatically,
when the Screen is initializing. B. Programmatically, using a
Refresh Data node in a Screen Action. C. Automatically, when the
Aggregates set to run "At Start" finish. D. Programmatically, using
a Server Action. - B. Consider that we want to apply aggregation
functions in an Aggregate. Which of the following options is false? A.
We can apply multiple aggregation functions inside an Aggregate. B.
The output of the Aggregate will contain all attributes from the
Source Entities plus the aggregation columns. C. We can apply the
following functions on attributes of integer data type: sum, max,

, min, count and average. D. The output of the Aggregate will not
include the columns at grey. - B. Consider the Action called
Absolute
(https://drive.google.com/file/d/1whQveFFlesOJlkA1Qi4JMEV7-
oUAZU1f/view?usp=sharing) which returns an absolute value (abs)
of a number N passed as Input Parameter. When does the Action
return 0 ? A. Never. B. When the input parameter (N) is less than
zero. C. When the input parameter (N) is zero. D. When the input
parameter (N) is greater than zero. - C. Consider the following
Action (https://drive.google.com/file/d/1L6qUwd2jjqWAluUB-
Kv5gQghendWoMr2/view?usp=sharing), that calculates the square
root (sqrt) of a positive decimal number (N). Knowing that the
function was called with N = 0, and the debugger is stopped at the
Start node, what will happen when the developer selects the
Continue (F9) option highlighted in the picture? A. The Action will
end, with sqrt = 0. B. The Action will throw an exception and sqrt
will have no value. C. The debugger will stop in the N < 0 If node. D.
The debugger will stop at the breakpoint in the End node. - D.
Consider the following Pagination
(https://drive.google.com/file/d/1r1xbok0WwGQ3MYyhGmj1oVDC
z6rVfDA3/view?usp=sharing) that is associated with an already
implemented Table on a Screen. There are no errors in Service
Studio, but when the user selects a new page (in the pagination
widget) the results do not change on the Table. What is the reason
for that behavior? A. The GetMovies Aggregate is not being
refreshed in the OnNavigate Action. B. The Max. Records of the
Aggregate should be equal to the total number of movies in the
database. C. The Table is not being refreshed on the OnNavigate
Action. D. The Max Records property of the Pagination should be
set to GetMovies.Count and the TotalCount to RecordsPerPage. - A.
Consider the following Server Action. What happens if the
GetEmployeeById
