Q16. What are known patterns for the adaptation of interfaces? (Choose two.)

Bridge

Tower

Q17. You are the software architect of a system that has run for many years and been extended repeatedly. An analysis of the source code has revealed a multitude of dependencies between the classes.
Which of the following measures are possible solutions? (Assign all answers.)

Q18. What is the purpose of defining the system context? (Assign all answers.)

Explanation:
The purpose of defining the system context includes:
* To illustrate the system’s interfaces with external systems (B) – True
* To clarify the area of responsibility of the software architect C – True
* To represent the external systems (D) – True
* To distinguish between infrastructure and application (E) – True
* To distinguish between the hardware and software of a solution (F) – True Defining the system context is a crucial step in software architecture as it helps to establish the boundaries and interactions of a system within its environment. Here’s a detailed explanation of the purposes:
* To Illustrate the System’s Interfaces with External Systems (B): It is essential to understand how the system interacts with other systems, which can influence requirements and design1.
* To Clarify the Area of Responsibility of the Software Architect : By defining the system context, the architect’s responsibilities regarding the system’s interactions and boundaries are made clear1.
* To Represent the External Systems (D): The system context helps identify and represent all external entities that interact with the system, which is important for comprehensive design and analysis1.
* To Distinguish Between Infrastructure and Application (E): Understanding the system context allows for a clear distinction between the infrastructure (the environment in which the application operates) and the application itself1.
* To Distinguish Between the Hardware and Software of a Solution (F): The system context helps to differentiate between the hardware components and the software components of a system, which is vital for system integration and deployment1.
These aspects of the system context are fundamental for ensuring that the system is designed and developed to meet its intended goals and operate effectively within its designated environment.

Two building blocks offer operations with the same name.

A building block only contains operations that belong together logically.

A building block uses internal data structures of another building block.

Q22. Conway’s law sometimes is referred to as “If you have four teams working on the compiler, you’ll get a 4-pass compiler.” Which interpretations of this law are true, which are false? (Assign all answers.)

Q23. In a customer project the architecture shall be based on components. The requirements have not been fully determined yet.

open for extension

small component size

The suitability of the software design for its purpose

The software is free of errors

Q27. What do you have to take into account when designing external interfaces? (Choose three.)

Volatility of neighbouring systems

Adequate usage of the broker pattern

Protocols enforced by neighbouring systems

Expected amount of parallel calls

Numbered lists of sequential steps

Q30. What are the four key terms in common definitions of software architecture? (Choose four.)

Source code

Building Blocks

Functionality

Relationships

Components

Requirements

Interfaces

Q31. You want to demonstrate to colleagues that certain building blocks are suitable for the implementation of a use-case scenario.
Which of the following UML diagrams is best suited for this?

Use-case diagram

Sequence diagram

Activity diagram

Class diagram

Q32. Which two of the following requirements are examples of quality requirements? (Choose two.)

Up to 40,000 requests per day

User should be able to select the sort order freely.

Spelling is corrected automatically.

Failure rate is less than 0.1%.

Q33. Decide if the following statements are true or false. The performance of a system (response time or throughput) often competes with its… (Assign all answers.)

Q34. You are supposed to choose a software-architecture modeling tool for a software-development project. You create a suitable criteria catalogue for the choice of appropriate tools.
Which of the following factors can play a role in this? (Assign all answers.)

Q35. Which of the following statements apply to design patterns? (Choose two.)

Design patterns are not invented but discovered.

Design patterns should always be described alongside the problem they are supposed to solve.

Design patterns are formally defined and can thus be proven to be correct.

The number of design patterns used is proportional to the software architecture’s quality.

Q36. How does management and architects work together? Decide which statements are true and which are false.
K-Question. Assign all answers

Q37. What do you have to take into account when designing external interfaces? P-Question: From the following 6 answers select 3 that fit best.

Volatility of neighbouring systems

Adequate usage of the broker pattern

Protocols enforced by neighbouring systemst

Expected amount of parallel calls

Ease of implementation

Effect on the coupling in the building block view

Q38. Which of the following statements about (crosscutting) concepts are most appropriate? (Select four.)

The definition of appropriate concepts ensures the conceptual integrity of the architecture.

Concepts are a means to increase consistency.

For each quality goal there should be an explicitly documented concept.

Uniform exception handling is most easily achieved when architects agree with developers upon a suitable concept prior to implementation.

A concept might be implemented by a single building block.

Uniform usage of concepts reduces coupling between building blocks.

A concept can define constraints for the implementation of many building blocks.

To prepare for the ISQI CPSA-FL Certification Exam, candidates can take advantage of a range of resources, including study guides, practice exams, and training courses. The ISAQB (International Software Architecture Qualification Board) provides a comprehensive syllabus and study materials that cover all the topics included in the exam. Candidates can also attend training courses offered by authorized training providers to gain hands-on experience and practical knowledge of software architecture concepts.
