QUESTION 162
This question requires that you evaluate the underlined text to determine if it is correct.
A data dictionary that describes the structure of a database is called metadata.
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.

QUESTION 163
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. |
encapsulation |
B. |
superclassing |
C. |
polymorphism |
D. |
overloading |
Correct Answer: C
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.

QUESTION 166
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 |
Correct 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 dec
lared 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.
QUESTION 167
DRAG DROP
You are extending an application that stores and displays the results of various types of foot races. The application contains the following definitions:
The following code is used to display the result for a race:
The contents of the console must be as follows:
You need to implement the FootRace class.
Match the method declaration to the method body.
To answer, drag the appropriate declaration from the column on the left to its body on the right. Each declaration may be used once, more than once, or not at all. Each correct match is worth one point.
Correct Answer:
QUESTION 168
Which type of Windows application presents a parent window that contains child windows?
A. |
Multiple-document interface (MDI) |
B. |
Command-line interface (CLI) |
C. |
Single-document interface (SDI) |
D. |
Application programming interface (API) |
Correct Answer: A
Explanation:
A multiple document interface (MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single document interfaces (SDI) where all windows are independent of each other.
QUESTION 169
You are creating a Web application. The application will be consumed by client computers that run a variety of Web browsers.
Which term is used to describe the process of making the application available for client computers to access?
A. |
Deploying |
B. |
Hosting |
C. |
Virtualization |
D. |
Casting |
Correct Answer: B
Explanation:
You host web applications.
QUESTION 170
You are developing a webpage that enables students to manage races.
The webpage will display two lists: past races and upcoming races. The page also contains a sidebar with contact information and a panel with social media settings that can be edited. Race results can be shared on social media.
