4.

Every project should document its architecture
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
While it is important to document the architecture of a project, it is not necessary for every project to do so. The extent of documentation required may vary depending on the size, complexity, and criticality of the project. Smaller projects or projects with simple architectures may not require extensive documentation, while larger and more complex projects may benefit from detailed architecture documentation to aid in understanding, maintenance, and future development. Therefore, it is not true that every project should document its architecture.

Rate this question:
5.

Architecture documents are abstractions of the system.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Architecture documents are abstractions of the system because they provide a high-level overview and representation of the system's structure, components, and interactions. They focus on the essential aspects of the system's design and functionality, omitting unnecessary details. By abstracting the system, architecture documents facilitate communication and understanding among stakeholders, allowing them to grasp the system's overall concept and make informed decisions. These documents serve as a blueprint for the system's development, guiding the implementation process and ensuring that the system aligns with the desired architecture.

Rate this question:
6.

A good set of architectural documents will completely describe the system
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
A good set of architectural documents may provide a comprehensive overview of the system, but it is unlikely to completely describe the system. Architectural documents typically focus on the high-level structure, components, and interactions of the system, but they may not capture every detail or implementation aspect. Complete system description would require detailed specifications, design documents, and other supporting documentation. Therefore, the statement that a good set of architectural documents will completely describe the system is false.

Component details in UML can be shown as text within a compartment of a component
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
In UML, component details can be represented as text within a compartment of a component. This allows for a clear and organized representation of the component's attributes, operations, and other details. By including this information within a compartment, it becomes easier to understand and analyze the structure and behavior of the component. Therefore, the statement "Component details in UML can be shown as text within a compartment of a component" is true.

Correct Answer
C. A class diagram supports analyzing behavior of complex protocols.

Explanation
The given correct answer is "A class diagram supports analyzing behavior of complex protocols." This answer is correct because a class diagram is a visual representation of the structure and relationships of classes in a system, and it is commonly used in software engineering to analyze the behavior of complex protocols. By modeling the classes and their relationships, a class diagram can help in understanding how different classes interact and communicate with each other, which is essential for analyzing the behavior of complex protocols.

Which of the following is(are) NOT well supported by the class diagram notation? ___________.
- A.
  
  Identifying public and private members of a class.
- B.
  
  Identifying which classes depend on other classes.
- C.
  
  Discussing how the system will behave.
- D.
  
  Discussing how to add newly required functionality to the system.
- E.
  
  Both a and d
Correct Answer
C. Discussing how the system will behave.

Explanation
The class diagram notation in UML is primarily used to represent the structure and relationships between classes in a system. It is not well supported for discussing how the system will behave, as it focuses more on the static aspects of the system rather than its dynamic behavior. The class diagram is more suitable for identifying public and private members of a class and identifying dependencies between classes. It can also be used to discuss how to add newly required functionality to the system by representing the relationships between classes and their methods. Therefore, the correct answer is "Discussing how the system will behave."

  B.Help the project sponsors understand how the system will work.
- C.
  
  C.Help the project manager identify responsible people for each of the coding tasks.

- G.
  
  Each of a, c, and d.
- H.
  
  Each of b, c, and d.
Correct Answer
B. B.Help the project sponsors understand how the system will work.

Explanation
Including class diagrams in project documentation helps programmers understand the context of the code they are creating, helps the project manager identify responsible people for each coding task, and helps maintainers identify the source of bugs. However, it does not directly help the project sponsors understand how the system will work. Class diagrams primarily focus on the structure and relationships of the code, rather than providing a comprehensive understanding of the system's functionality.

Class diagrams can be generated directly from code.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Class diagrams can be generated directly from code. This means that it is possible to automatically generate a class diagram by analyzing the code of a software system. This can be done using certain tools or software that are capable of parsing the code and extracting the necessary information to create the class diagram. By doing so, developers can save time and effort in manually creating the class diagram, especially for larger and more complex systems. This automated process can help in visualizing the structure and relationships between classes, making it easier to understand and maintain the codebase.

The process of creating class diagrams is a valuable activity during design.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Creating class diagrams is a valuable activity during design because it helps in visualizing the structure and relationships of classes in a system. Class diagrams provide a high-level overview of the system's architecture, allowing designers to identify and define the classes, their attributes, and their associations. This helps in understanding the system's design and facilitates communication among stakeholders. Additionally, class diagrams serve as a blueprint for implementation, guiding the development process and ensuring that the system is designed in a modular and organized manner.

All class diagrams created during design of a system should be maintained as part of the project documentation.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Not all class diagrams created during the design of a system need to be maintained as part of the project documentation. The decision to include a class diagram in the project documentation should be based on its relevance and usefulness for understanding the system's design. Some class diagrams may be discarded or updated as the design evolves, while others may be kept as important references for future development or maintenance. Therefore, it is not necessary to maintain all class diagrams as part of the project documentation.

- E.
  
  Both a and c
- F.
  
  All of a-d.
Correct Answer
F. All of a-d.

Explanation
The correct answer is "All of a-d." This is because a design pattern contains a description of other related patterns, can be useful in describing how a software problem was solved by a developer, is a general reusable solution to a commonly occurring problem within a given context in software design, and gives examples of code that used the pattern. Therefore, all of the options mentioned in the question are correct.

The Dependency Inversion Principle ______.
- A.
  
  Helps ensure that objects are highly reusable.
- B.
  
  Requires that methods that are present in base classes must also be present in the derived classes.
- C.
  
  Helps ensure that objects are easy to extend without requiring change to the original object.
- D.
  
  Requires that object interfaces only include methods that will be needed by most implementers.
- E.
  
  Helps make changing an object easier.
Correct Answer
A. Helps ensure that objects are highly reusable.

Explanation
The Dependency Inversion Principle helps ensure that objects are highly reusable by promoting loose coupling between classes. It states that high-level modules should not depend on low-level modules, but both should depend on abstractions. This allows for flexibility and interchangeability of components, making it easier to reuse them in different contexts without making significant changes to the original objects. By depending on abstractions instead of concrete implementations, the code becomes more modular and adaptable, leading to increased reusability.
