NEW QUESTION 1

The throw keyword is used to perform which two actions? (Choose two.)

• A. stop processing of the code
• B. move error handling to a separate thread
• C. raise exceptions
• D. re-throw exceptions as a different type

Answer: CD

Explanation:
* The Throw statement throws an exception that you can handle with structured exception-handling code (Try...Catch...Finally) or unstructured exception- handling code (On Error GoTo). You can use the Throw statement to trap errors within your code because Visual Basic moves up the call stack until it finds the appropriate exception- handling code.
* This example throws an ApplicationException exception. Throw New ApplicationException

NEW QUESTION 2

The Dog class and the Cat class inherit from the Animal class. The Animal class includes a breathe() method and a speak() method. If the speak() method is called from an object of
type Dog, the result is a bark. If the speak() method is called from an object of type Cat, the result is a meow.
Which term is used to describe this object-oriented concept?

• A. multiple inheritance
• B. encapsulation
• C. polymorphism
• D. data hiding

Answer: C

Explanation:
Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Polymorphism is a Greek word that means "many-shaped" and it has two distinct aspects:
* At run time, objects of a derived class may be treated as objects of a base class in places such as method parameters and collections or arrays. When this occurs, the object's declared type is no longer identical to its run-time type.
* Base classes may define and implement virtual methods, and derived classes can override them, which means they provide their own definition and implementation. At run- time, when client code calls the method, the CLR looks up the run-time type of the object, and invokes that override of the virtual method. Thus in your source code you can call a method on a base class, and cause a derived class's version of the method to be executed.

NEW QUESTION 3

In the application life cycle, the revision of an application after it has been deployed is referred to as:

• A. Monitoring

NEW QUESTION 4

You run the following code:

What is the value of result when the code has completed?

• A. 10
• B. 20
• C. 30

Answer: B

Explanation:
The conditional-OR operator (||) performs a logical-OR of its bool operands. If the first operand evaluates to true, the second operand isn't evaluated. If the first operand evaluates to false, the second operator determines whether the OR expression as a whole evaluates to true or false.

Incorrect:
Not A, not C: ID is autogenerated and should not be specified.

Incorrect:
Date: Defines a date.
sByte: The sbyte keyword indicates an integral type that stores values in the range of -128 to 127.

NEW QUESTION 8

This question requires that you evaluate the underlined text to determine if it is correct.
The Response.Redirect method is used to transfer processing of the current page to a new page, and then return processing back to the calling page once processing of the new page has completed.
Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct.

• A. No change is needed
• B. Server.Transfer method
• C. Server.Execute method
• D. meta http-equiv="refresh" tag

Explanation:
The Execute method calls an .asp file, and processes it as if it were part of the calling ASP script. The Execute method is similar to a procedure call in many programming languages.
Incorrect:
* Response.Redirect Method
The Redirect method causes the browser to redirect the client to a different URL.
* The Server.Transfer method sends all of the information that has been assembled for processing by one .asp file to a second .asp file.

Two classes named Circle and Square inherit from the Shape class. Circle and Square both inherit Area from the Shape class, but each computes Area differently.
Which term is used to describe this object-oriented concept?

• A. polymorphism
• B. encapsulation
• C. superclassing
• D. overloading

Answer: A

Explanation:
You can use polymorphism to in two basic steps:
Create a class hierarchy in which each specific shape class derives from a common base class.
Use a virtual method to invoke the appropriate method on any derived class through a single call to the base class method.

This question requires that you evaluate the underlined text to determine if it is correct.
The duplication of code so that modifications can happen in parallel is known as separating.
Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct.

If you copy one or more areas of your code into a separate branch, you can update one copy while you preserve the original version, or you can update both branches to meet different needs. Depending on your development goals, you can later merge the changes from multiple branches to create a single version that reflects all changes
