質問 # 27
Concerning external interfaces, Postel's law suggests: "Be conservative in what you do, be liberal in what you accept from others." Assume that Postel's law has been consistently applied in your system. (Assign all answers.)
正解：
解説：
Explanation:
A) FalseB) FalseC) FalseD) TrueE) TrueF) False
Postel's law, also known as the robustness principle, is a guideline in software engineering that advises to "be conservative in what you do, be liberal in what you accept from others"1. This principle has implications for system design and interaction with external interfaces:
A) Response time of the system is reduced: This is false. Postel's law does not directly relate to the response time of a system1.
B) Implementation effort increases: This is false. Being liberal in what is accepted can actually simplify implementation because the system is designed to handle a wider range of inputs without failure1.
C) Usability of the system is reduced: This is false. Postel's law aims to increase robustness and interoperability, which can enhance usability by making the system more resilient and accommodating1.
D) Robustness of the system is increased: This is true. By being conservative in outputs and liberal in inputs, the system becomes more robust, handling a variety of inputs without error1.
E) The integrity of the data transferred via interfaces is increased: This is true. Accepting a wide range of inputs and adhering strictly to output specifications helps maintain data integrity across different systems1.
F) Availability of the system is reduced due to potentially bad quality of input data: This is false. Postel's law suggests that the system should be designed to handle poor quality input data gracefully, thus maintaining availability1.
Applying Postel's law helps create systems that are more tolerant of input variations and strict in their outputs, contributing to overall system robustness and reliability1.
質問 # 28
Which of the following statements regarding the design principle 'information hiding' are true and which are false? (Assign all answers.)
正解：
解説：
Explanation:
The statements regarding the design principle 'information hiding' that are true and false are as follows:
* True:
* Adhering to the 'information hiding' principle increases flexibility for modifications (A).
* Information hiding involves deliberately hiding information from callers or consumers of the building block (B).
* In object-oriented development, information hiding is primarily relevant at class level (E).
* False:
* Information hiding makes it harder to distinguish between interface and implementation C.
* Information hiding is a derivative of the approach of incremental refinement along the control flow (D).
The principle of 'information hiding' is a fundamental concept in software engineering that promotes encapsulation and abstraction. Here's an explanation of each statement:
* True Statements:
* (A): Information hiding allows for changes in the implementation without affecting other parts of the system, thus increasing flexibility1.
* (B): The core idea of information hiding is to keep the implementation details away from the users of the component, revealing only what is necessary2.
* (E): In object-oriented programming, information hiding is typically applied at the class level, where internal data and methods are hidden from other classes3.
* False Statements:
* C: Information hiding does not make it harder to distinguish between interface and implementation; rather, it helps to clearly define the interface by hiding the implementation details1.
* (D): Information hiding is not a derivative of incremental refinement along the control flow; it is a separate principle that focuses on hiding the internal complexities of a component4.
Information hiding is crucial for maintaining a clean and modular architecture, where components can be developed, maintained, and replaced independently.

質問 # 30
In your project, three architects and seven developers are working on the documentation of the software architecture.
Which methods are appropriate in order to achieve a consistent and adequate documentation, and which are not? (Assign all answers.)
正解：
解説：
Explanation:
A) Not AppropriateB) AppropriateC) Not Appropriate
For a project involving multiple architects and developers, achieving consistent and adequate documentation is crucial. Here's how the methods listed would fare:
A) The chief architect creates the documentation: This method is not appropriate because it places the entire burden of documentation on a single individual, which can lead to bottlenecks and may not accurately reflect the contributions and insights of the entire team1.
B) Identical templates are used for the documentation: This is an appropriate method as it ensures consistency across the documentation produced by different team members. Using identical templates helps maintain a uniform structure and style, which is beneficial for readability and maintenance1.
C) All parts of the architecture documentation are automatically extracted from the source code: Relying solely on automatic extraction is not appropriate because it may not capture all the necessary details and decisions made during the architectural design process. Manual documentation is also important to provide context and rationale that cannot be automatically generated1.
These methods are in line with the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL, which emphasizes the importance of clear, consistent, and comprehensive documentation practices1.
質問 # 31
Which characteristics of a building block are only visible in the whitebox view, and for which characteristics does the blackbox view suffice? (Assign all answers.)
正解：
解説：
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.

質問 # 32
Which of the following statements are correct? (Choose two.)
- A. A stack usually only provides access to one element at a time.
- B. A stack is organized according to the FIFO principle.
- C. The push operation usually places a new element onto a stack.
- D. A stack acts exactly like a queue.
正解：A、C
解説：
The correct statements about data structures, specifically stacks, are:A. The push operation usually places a new element onto a stack. - This is the basic operation of a stack data structure, where elements are added to the top of the stack.D. A stack usually only provides access to one element at a time. - In stack terminology, this is known as LIFO (Last In, First Out) behavior, where only the top element is accessible at any time for operations like pop or peek.

質問 # 35
What is the main benefit of the layered architectural pattern? (Assign all answers.)
正解：
解説：
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.

質問 # 36
Which of the following principles apply to testing? (Choose two.)
- A. In general, exhaustive testing is not possible.
- B. Error-free test runs also mean: the software is usable.
- C. Sufficient testing will show that a program is free of errors.
- D. Where many errors exist, more errors are usually hidden.
正解：A、D
解説：
The principles that apply to testing include:A. In general, exhaustive testing is not possible. - It is widely recognized in software testing that it is not feasible to test every possible input or state of a software application due to the vast number of variations and combinations, especially in complex systems.B. Where many errors exist, more errors are usually hidden. - This principle, often referred to as the pesticide paradox in software testing, suggests that discovering numerous bugs in a specific area of the software often indicates the presence of additional, less obvious bugs.
