Question: 212

Choose the best description of the following line of code (assume n_tr_tran is a descendant of the system class transaction): n_tr_tran = create n_tr_tran 

Answer

An instance of n_tr_tran will be created in memory, because no refereneces exist for it, the object will be destroyed.

This code will load the n_tr_tran class into the class pool, but no objects will be created in memory.

This code will not compile, because n_tr_tran is not a valid  reference variable.

The n_tr_tran object will be created and a global reference variable of the same name will automatically be declared.

Question: 213

A class that becomes instantiated is called: 

Answer

an extension class.

an abstract class.

a base class.

a concrete class.

Question: 214

Identify the TRUE statements with regard to external functions? (Choose 3) 

Answer

Global external functions are available anywhere in the application but can also be restricted as a part of the object’s definition.

External subroutines are the same as external functions except that they return a value.

Local external functions must be declared before using it in script.

Global external functions do not need to be declared before using them in script.

Local external functions are part of the object’s definition and can always be used in scripts for the object itself.

Local external functions can be made accessible to scripts other than that of the object for which it has been declared.

Question: 215

An event is defined with arguments. If it is invoked via the TriggerEvent() or PostEvent() functions 

Answer

The event will ail silently

Attempts to access the arguments will result in a run-time error.

The arguments are initialized to appropriate default values.

The arguments will be NULL.

Question: 216

Which of the following statements are TRUE when using the DYNAMIC keyword? (Choose 2) 

Answer

When using the DYNAMIC keyword the actual method signature is determined at execution time.

The DYNAMIC keyword indicates that it is Strongly typed by the compiler.

The DYNAMIC keyword applies only to methods that are associated with an object.

You can call Global functions using the DYNAMIC keyword.

Question: 217

Identify the CORRECT statements with regard to the AncestorReturnValue variable? (Choose 2) 

Answer

The AncestorReturnValue variable is generated if you extend the ancestor script and use the CALL syntax to call the ancestor event script.

When you extend an event, the compiler automatically generates a local variable called AncestorReturnValue.

When you extend an event, the compiler automatically generates an instance variable called AncestorReturnValue.

The AncestorReturnValue variable is generated if you override the ancestor script and use the CALL syntax to call the ancestor event script.

Question: 218

Class n_utility consists primarily of general utility functions and has the AutoInstantiate property set. A global variable of class n_utility, gnv_utility, is declared in the application. Which of the following are TRUE? (Choose 3) 

Answer

gnv_utility is accessible throughout the application.

n_utility’s methods and properties may be accessed directly through the class.

The statement “gnv_utility = CREATE n_utility” may be used to reinitialize the instance.

If n_utility declares an instance variable of class n_utility, the object will not save.

n_utility represents an appropriate use of the AutoInstantiate property.
