Question 1

Most complex products are built ________.

Accepted Answer

Most complex products are built from independent parts, which allows for easier manufacturing, maintenance, and customization.

Question 2

The advancement of technology is ________.

Accepted Answer

C

Question 3

________ products are made possible only when the availability of what they require, be it tangible or intangible, achieves a critical mass.

Accepted Answer

Complex or revolutionary products often require a critical mass of resources, technology, or infrastructure to be viable or successful.

Question 4

Reuse helps with ________.

Accepted Answer

Reuse helps improve productivity by saving time and effort, manage complexity by using proven solutions, and reduce costs by minimizing the need for new resources.

Question 5

Reuse can apply to development activities such as ________.

Accepted Answer

Reuse can apply to all development activities, including analysis, design, and implementation.

Question 6

Reuse can apply to any ________ that is required in software development.

Accepted Answer

Reuse can apply to any product, experience, or expertise that is required in software development, encompassing a broad range of resources.

Question 7

________ is (are) the most obvious, the most reliable and the most effective mechanism for reuse.

Accepted Answer

Components are self-contained units of software that can be easily reused across different applications, making them the most obvious, reliable, and effective mechanism for reuse.

Question 8

Patterns encapsulate experience in solving problems and they:

Accepted Answer

Patterns encapsulate general solutions to common problems in software design and must be adapted to fit the specifics of any given problem. They are not plug-and-play solutions but rather templates that guide problem-solving.

Question 9

________ is a service that provides platform-independent application logic to consumers across the Web.

Accepted Answer

Web services are designed to support interoperable machine-to-machine interaction over a network. They provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks.

Question 10

The most obvious, the most reliable, and the most effective mechanism for reuse is ________.

Accepted Answer

Components are designed to be reused across different programs and systems, making them the most obvious, reliable, and effective mechanism for reuse. Patterns provide a template for solving problems, refactoring improves the design of existing code, and Web services allow for interoperability between different systems, but components are specifically built for reuse.

Question 11

________ provide(s) the guidelines for discovering the solution.

Accepted Answer

Methodology provides a systematic, planned approach that guides all the stages of a project, including the process of discovering solutions.

Question 12

Source code reuse is advisable when solving ________.

Accepted Answer

Source code reuse is most advisable for problems requiring cookbook solutions, as these problems typically have well-established methods for solving them, making it efficient to reuse existing code.

Question 13

________ is one of the basic concepts of object orientation and is theoretically significant but not very helpful if it cannot be put into practice.

Accepted Answer

Inheritance is a fundamental concept in object-oriented programming that allows a class to inherit properties and methods from another class. While it is crucial for understanding and using object-oriented principles, its theoretical significance might not be very apparent without practical application and examples.

Question 14

Implementation inheritance is a mechanism where a(n) ________ can reuse, extend, or override the attributes and the operations of its parent.

Accepted Answer

Subclass is the correct term for a class that inherits from another class, allowing it to reuse, extend, or override the attributes and operations of its parent class.

Question 15

Subclassing is a kind of inheritance in which the subclass inherits not only the features but also the ________ of its superclass.

Accepted Answer

Subclassing allows the subclass to inherit the functionality (methods) of its superclass, in addition to attributes.

Question 16

A subclass may add ________ that do not exist in the superclass.

Accepted Answer

A subclass can add attributes, operations, and extensions that do not exist in the superclass, making D the correct choice. This is a fundamental concept in object-oriented programming, allowing for the extension and customization of classes.

Question 17

The concept of ________ is used when a superclass can provide specialized services through its subclasses.

Accepted Answer

Polymorphism allows a superclass to define methods that can be overridden by subclasses, enabling objects of different subclasses to be treated as objects of the superclass but still respond differently to the same method call. This concept is key in allowing a superclass to offer specialized services through its subclasses.

Question 18

________ is a mechanism by which multiple classes share one interface but implement that interface independently of each other or of the parent class.

Accepted Answer

Interface inheritance allows different classes to use the same interface while implementing its methods in their own unique ways, thus sharing a common interface but behaving independently.

Question 19

In ________ a subclass is responsible for implementing each and every attribute and/or operation of the superclass.

Accepted Answer

Interface inheritance requires the subclass to implement all the methods and attributes defined in the superclass's interface, ensuring that the subclass adheres to a specific contract or interface defined by the superclass.

Question 20

The purpose of interface inheritance is to arrive at a subclass that ________.

Accepted Answer

Interface inheritance allows a subclass to implement the same services or methods defined in the interface but allows for different implementations, thus performing the same services in different ways.
