Every project should document its architecture.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
While it is generally recommended to document the architecture of a project, it is not an absolute requirement for every project. The decision to document the architecture depends on various factors such as the complexity of the project, the size of the team, the need for future maintenance or scalability, and the project's specific requirements. Some smaller or simpler projects may not require extensive documentation of their architecture, whereas larger or more complex projects may benefit from having detailed documentation to aid in understanding, communication, and future development.Rate this question:
-

Architecture documents are abstractions of the system.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Architecture documents are abstractions of the system because they provide a high-level overview of the system's structure, components, and interactions. These documents focus on capturing the essential elements and relationships, while omitting unnecessary details. By abstracting the system, architecture documents help stakeholders understand the system's design and make informed decisions. They serve as a blueprint for development, communication, and collaboration among team members. Therefore, it is true that architecture documents are abstractions of the system.Rate this question:
-
- 6.
A good set of architectural documents will completely describe the system
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A good set of architectural documents may provide a comprehensive overview of the system, but it is unlikely to completely describe the system. Architecture documents typically focus on high-level design decisions, key components, and their interactions. However, they may not cover every single detail, implementation specifics, or changes that occur over time. Therefore, while architectural documents are valuable for understanding the system's structure and design principles, they are not expected to provide an exhaustive and complete description of the entire system.Rate this question:
-
- 7.
All design decisions should be made before coding begins
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false because design decisions can and often should be made throughout the coding process. As developers gain a better understanding of the requirements and constraints of the project, they may need to adjust their design decisions accordingly. Additionally, new ideas or technologies may emerge during the coding process that could warrant changes to the initial design. Therefore, design decisions are not fixed and can be made and modified as needed throughout the coding process.Rate this question:
-

Different types of models are required in order to serve the needs of various stakeholders.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is incorrect. Different types of models are not required to serve the needs of various stakeholders. Models are tools used to represent and understand complex systems or concepts. While different stakeholders may have different needs and perspectives, it is not necessary to have different types of models to serve those needs. A single model can be used to address the requirements of multiple stakeholders by incorporating their perspectives and requirements into the model. Therefore, the correct answer is False.Rate this question:

D) Lollipop symbol is used to represent provides interfaces.
- E.
E) Socket symbol is used to represent provides interfaces.
Correct Answer
C. C) A class diagram supports analyzing behavior of complex protocols.Explanation
A class diagram is a visual representation of the structure and relationships of classes in a system. It is commonly used in object-oriented programming to model the behavior and interactions between different classes. While options a) and b) are partially correct, they do not capture the full purpose of a class diagram. Option c) is the most correct because analyzing the behavior of complex protocols is one of the main uses of a class diagram. Options d) and e) are incorrect as the lollipop symbol represents an interface and the socket symbol represents a connection or communication between components, not specifically providing interfaces.Rate this question:

Class diagrams can be generated directly from code
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Class diagrams can be generated directly from code by using various tools and technologies. These tools analyze the code and extract information about the classes, their attributes, and their relationships. They then generate a visual representation of the classes and their relationships, which is known as a class diagram. This diagram helps in understanding the structure and organization of the code, making it easier to comprehend and maintain. Therefore, the statement "Class diagrams can be generated directly from code" is true.Rate this question:

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. FalseExplanation
The statement suggests that all class diagrams created during the design of a system should be maintained as part of the project documentation. However, this is not necessarily true. While class diagrams are useful for understanding the structure of a system and can be helpful during the design phase, they may not always be necessary to include in the project documentation. The decision to include class diagrams in the documentation should be based on the specific requirements and needs of the project.Rate this question:
