Software Engineering QUIZ 6

2.

The prototyping model of software development is ____________.

A reasonable approach when requirements are well defined.
A useful approach when a customer cannot define requirements clearly.
The best approach to use for projects with large development teams.
A risky model that rarely produces a meaningful product.

Correct Answer

A. A useful approach when a customer cannot define requirements clearly.

Explanation

The prototyping model of software development is a useful approach when a customer cannot define requirements clearly. This is because the prototyping model allows for the creation of a working prototype of the software early in the development process. This prototype can then be used to gather feedback from the customer and make necessary changes and refinements to the requirements. This iterative process helps in clarifying the requirements and ensures that the final product meets the customer's needs and expectations.

In software engineering, _________ is a general reusable solution to a commonly occurring problem in software design.

Modularity
Pattern
Architecture
Design model

Correct Answer

A. Pattern

Explanation

In software engineering, a pattern refers to a general reusable solution to a commonly occurring problem in software design. It is a proven approach that can be applied to different situations to solve similar problems. Patterns provide a way to standardize and organize software development, making it easier for developers to understand and communicate complex design concepts. By using patterns, developers can save time and effort by leveraging existing solutions rather than starting from scratch for every problem they encounter.

The open source movement has meant that there is a huge reusable code base available at

free of cost
Low cost
High cost
short period of time

Correct Answer

A. Low cost

Explanation

The open source movement has led to the availability of a vast amount of reusable code at a low cost. Open source software is typically free to use, modify, and distribute, which means that developers can access and utilize code created by others without having to pay for it. This has significantly reduced the cost of software development, as developers can leverage existing open source code instead of building everything from scratch. Therefore, the correct answer is "low cost".

COTS product reuse means

Class and function libraries that implement commonly used abstractions are available for reuse.
Shared components are woven into an application at different places when the program is compiled.
Large-scale systems that encapsulate generic business functionality and rules are configured for an organization.
Systems are developed by configuring and integrating existing application systems.

Correct Answer

A. Systems are developed by configuring and integrating existing application systems.

Explanation

COTS product reuse refers to the practice of developing systems by configuring and integrating existing application systems. This means that instead of building a system from scratch, organizations use pre-existing software components and configure them to meet their specific needs. This approach saves time and resources as it leverages the functionality and features already available in the existing systems. It also allows for faster development and deployment of new systems by utilizing proven and tested components.

Which type of relationship is suitable for arrow labeled with A?

Uses
Extends
Inheritance
Actor

Correct Answer

A. Uses

Explanation

The arrow labeled with A represents the "uses" relationship. In object-oriented programming, the "uses" relationship indicates that one class depends on another class to perform a specific task or provide a certain functionality. It means that the class represented by the arrow labeled with A utilizes the services or methods of the class it is connected to. This relationship is suitable when one class needs to make use of the functionality provided by another class but does not inherit from it or extend it.

7.

Which type of relationship is suitable for arrow labeled with B?

Uses
Extends
Inheritance
Actor

Correct Answer

A. Uses

Explanation

The arrow labeled with B represents a "uses" relationship. In software engineering, the "uses" relationship indicates that one class depends on another class to perform a specific function or use its services. This relationship is often depicted as a dotted line with an arrow pointing from the dependent class to the class being used.

Which of the following is a generic structure that is extended to create a more specific subsystem or application

Software reuse
Object-oriented programming language
Framework
None of the mentioned

Correct Answer

A. Framework

Explanation

A framework is a generic structure that provides a foundation for creating more specific subsystems or applications. It includes pre-written code and libraries that can be reused and extended to meet the specific needs of a project. Frameworks enable developers to save time and effort by providing a set of tools, guidelines, and reusable components. They promote code reuse, standardization, and modularity, making it easier to develop complex software systems. Therefore, a framework is the correct answer as it aligns with the definition and purpose described in the question.

What are generic application systems that may be designed to support a particular business type, activity, or sometimes a complete enterprise?

COTS-solution systems
COTS-integrated systems
ERP systems
Both COTS-solution and COTS-integrated systems

Correct Answer

A. COTS-solution systems

Explanation

COTS-solution systems refers to Commercial Off-The-Shelf software solutions that are designed to support specific business types, activities, or entire enterprises. These systems are pre-built and readily available in the market, allowing businesses to implement them without the need for extensive customization or development. They offer a range of functionalities and features that cater to the specific needs of different industries or business domains. Therefore, COTS-solution systems are generic application systems that can be tailored to support a particular business type or activity.

Which of the following is not an advantages of software reuse?

Lower costs
Faster software development
High effectiveness
Ower risks

Correct Answer

A. High effectiveness

Explanation

High effectiveness is not an advantage of software reuse. Software reuse primarily focuses on reducing costs, speeding up software development, and minimizing risks. While software reuse can improve the effectiveness of software development processes, it is not specifically listed as an advantage in this context.
