Explanation:
For a building block, the characteristics visible only in the whitebox view are:
* Code structure of the building block (D)
* Algorithms used in the building block (E)
* Implementation details for the security requirements of the building blocks (G) The blackbox view suffices for:
* Public interfaces of the building block (A)
* Test coverage based on unit tests for sub building blocks contained in the building block (B)
* Test coverage based on integration tests
* Security requirements of the building blocks (F)
In software architecture, the whitebox view reveals the internal workings of a building block, including its code structure, algorithms, and specific implementation details1. This view is essential when the internal structure and behavior of the component need to be understood or modified.
On the other hand, the blackbox view treats the building block as an opaque entity, focusing on its exposed interfaces and observable behaviors without revealing its internal structure2. This view is sufficient for understanding what the building block does from an external perspective, such as its public interfaces and how well it performs its functions as determined by testing.
Here's a breakdown of the characteristics:
* Whitebox View:
* Code Structure (D): This includes the organization of code within the building block, such as classes, interfaces, and other components.
* Algorithms (E): The specific algorithms used within the building block to perform its functions.
* Implementation Details for Security (G): The actual code and strategies used to fulfill the security requirements.
* Blackbox View:
* Public Interfaces (A): The interfaces that are exposed to other building blocks or systems.
* Test Coverage for Sub Building Blocks (B): The extent to which the unit tests cover the sub-components within the building block.
* Test Coverage for Integration Tests : The coverage of tests that verify the interactions between building blocks.
* Security Requirements (F): The security objectives and criteria that the building block must meet.

Explanation:
A) TrueB) FalseC) TrueD) True
A) The project plan from management is influenced by architectural decisions.
* True. Architectural decisions often have significant implications on the project plan, including timelines, resource allocation, and technical approaches1.
B) Cost estimates are primarily the responsibility of the architect.
* False. While architects may contribute to cost estimates, especially regarding design-related expenses, it is typically the management's responsibility to oversee and finalize cost estimates for the entire project2.
C) Architects advise project management on the definition of work packages.
* True. Architects play a crucial role in defining work packages, particularly in ensuring that the technical aspects of the project are accurately captured and planned for1.
D) Management and architects cooperate on handling of technical risks.
* True. Both management and architects need to work closely to identify, assess, and manage technical risks throughout the project2.

Explanation:

The layered architectural pattern, also known as n-tier architecture, is a common framework in software development that organizes a system into distinct layers with specific roles and responsibilities. The primary advantage of this pattern is its Separation of Concerns (SoC), which means each layer is independent and can be understood without the others2. This separation enhances flexibility because changes in one layer can be made with minimal impact on others, allowing for easier maintenance and scalability12.
While creating high-performance systems (B) and being able to use application servers are also considerations in system architecture, they are not the main benefits attributed to the layered pattern. The layered architecture is more about managing complexity and promoting modularity rather than directly enhancing performance or dictating the use of specific technologies like application servers34.

Explanation:
A) FalseB) FalseC) TrueD) TrueE) TrueF) True
A) Agile approaches make written documentation unnecessary. In such cases, verbal communication can substitute for documentation.
* False. Even in agile approaches, written documentation is important for maintaining a clear and
* consistent understanding of the architecture among team members and stakeholders1.
B) Written documentation makes verbal reiteration unnecessary.
* False. Verbal communication is essential for clarifying and reinforcing the content of written documentation, especially when addressing complex or nuanced architectural issues2.
C) Despite written documentation, verbal communication of architectural interrelationships is important.
* True. Verbal communication plays a crucial role in explaining the rationale behind architectural decisions and interrelationships that may not be fully captured in documentation2.
D) Documentation and communication should use identical terms and rationale.
* True. Consistency in terminology and rationale between documentation and verbal communication helps prevent misunderstandings and ensures that all parties have a common understanding of the architecture2.
E) Documentation should be created primarily for project participants who either cannot or do not want to read the system's source code.
* True. Documentation serves as a guide for those who may not be directly involved in coding but need to understand the architecture, such as managers, new team members, or external stakeholders2.
F) Communication and documentation complement each other: verbal communication helps architects determine what must be recorded in writing.
* True. Verbal communication often reveals what aspects of the architecture are most important or confusing to team members, guiding what should be emphasized in written documentation
