Question 1

The interface for a component in a component diagram is denoted by a ball or a port.

Accepted Answer

The interface for a component in a component diagram is denoted by a ball or a port.

Question 2

"Just in time" systems design is a popular technique used in adaptive approaches to projects.

Accepted Answer

"Just in time" systems design is a technique used in adaptive approaches, where work is done just in time to meet the needs of the project.

Question 3

Detailed Object-oriented design (OOD)is done on a use case-by-use case basis.

Accepted Answer

Detailed Object-oriented design (OOD) is done on a use case-by-use case basis. Each use case is analyzed separately and its specific requirements are defined, and then a corresponding design is created to meet those requirements. This iterative process continues until all the use cases have been analyzed and designed.

Question 4

Which of the following is NOT one of the categories of difference between networked based systems and Internet based systems.
A)State configuration"
B)Client configuration"
C)Server configuration"
D)Connectivity configuration"

Accepted Answer

The answer of Which of the following is NOT one...

Question 5

In object-oriented design,the design models are extensions of the analysis models.

Accepted Answer

In the object-oriented design process, the design models are built upon the analysis models and serve as extensions of them. The analysis models identify the requirements and behavior of the system, while the design models specify how those requirements will be implemented and structured in the system.

Question 6

It is usually a bad idea to try to include user-interface classes to a CRC design.

Accepted Answer

The answer of It is usually a bad idea to...

Question 7

Which analysis model serves as an input model to a design class diagram?
A)Use case diagram"
B)Activity diagram"
C)Domain model class diagram"
D)System sequence diagram (SSD)"

Accepted Answer

The domain model class diagram is the analysis model that represents the main classes and their relationships in the problem domain. It is used as an input to the design class diagram, which is the model that represents the solution domain. Therefore, option C is the correct answer. The other options are also analysis models, but they do not directly serve as inputs to design class diagrams.

Question 8

The primary difference between Web based systems and non-Internet systems is in how the view layer interacts with the domain and data access layers.

Accepted Answer

Web based systems rely on the internet to interact with the view layer, while non-Internet systems may use desktop or mobile applications to interact with the user interface. This difference in technology impacts how the view layer interacts with the domain and data access layers. In web based systems, the view layer often communicates with the domain and data access layers through APIs, while in non-Internet systems, the view layer may communicate with these layers more directly.

Question 9

One big difference between an Internet based system and a Client/Server system is that an Internet system maintains state information.

Accepted Answer

Internet-based systems are typically stateless, meaning they do not maintain state information between requests, unlike client/server systems which can maintain state information.

Question 10

One tenet of Agile philosophy is that while analysis models may be useful,it generally is not necessary to develop design models.

Accepted Answer

One tenet of Agile philosophy is that while analysis models may be useful, it is still important to develop design models to guide the implementation process and ensure that the system functions as intended.

Question 11

Ports and sockets are used to show the interface in what kind of UML diagram?
A)Deployment diagram"
B)Network diagram"
C)Package diagram"
D)Component diagram"

Accepted Answer

Ports and sockets are typically used in Component diagrams to show the interface of a component with its surroundings. A Component diagram shows the high-level architecture of a system or application and the dependencies between components. Therefore, option D is the correct choice.

Question 12

Which of the following is NOT part of a multilayer object-oriented design (OOD)?
A)Database access"
B)Problem domain object"
C)User input form"
D)Functional module"

Accepted Answer

Multilayer object-oriented design typically involves separating concerns into layers such as presentation (user input forms), business logic (problem domain objects), and data access (database access). Functional modules, while a part of software design, do not specifically pertain to the layered approach of OOD.

Question 13

Two layer architectures are interesting in theory,but are seldom if ever used.

Accepted Answer

Two layer architectures, also known as client-server architectures, are commonly used in software development. They consist of a client layer responsible for presenting information to the user and a server layer that manages data storage and processing. This architecture is widely used in web and mobile applications as well as enterprise software solutions.

Question 14

The objective of object-oriented detailed design is to identify and specify all the objects that must work together to carry out each use case.

Accepted Answer

The objective of object-oriented detailed design is to identify and specify all the objects that must work together to carry out each use case. This involves creating class diagrams, sequence diagrams, and other design artifacts that define the implementation details of the system. The result of this process is a detailed design document that serves as a blueprint for coding the system.

Question 15

The objective of object-oriented analysis is to identify the objects that must work together to carry out each use case.

Accepted Answer

The answer of The objective of object-oriented analysis is to...

Question 16

The most important model in object-oriented detailed design is a class diagram.

Accepted Answer

The answer of The most important model in object-oriented detailed...

Question 17

Developers do not typically add more classes to design class diagrams than were originally defined in the domain model.

Accepted Answer

Developers often add more classes to design class diagrams than were originally defined in the domain model to accommodate design considerations, implementation details, and software architecture requirements that were not apparent during the initial domain modeling phase.

Question 18

Which of the following diagrams is used for architectural design?
A)Interaction diagrams"
B)Package diagrams"
C)Sate machine diagrams"
D)Component diagrams"

Accepted Answer

Component diagrams are commonly used in architectural design to depict the high-level structure of a system, including its components and their relationships. Interaction diagrams are used for modeling the interactions between objects or components, package diagrams show how classes and other elements are organized into packages, and state machine diagrams represent the behavior of a system or object in response to input over time.

Question 19

Software systems can generally be divided into three types of systems: single-user systems,enterprise-level systems,and Web-based systems.

Accepted Answer

Software systems can be categorized in various ways, but the division into single-user, enterprise-level, and web-based systems is not a standard classification. Systems can be classified based on functionality, architecture, or deployment, among other criteria.

Question 20

The primary difference between a design class symbol and a problem domain class symbol is the addition of method signatures.

Accepted Answer

Design class symbols contain method signatures while problem domain class symbols do not.
