Book Preface: No Best Practices

What is the primary responsibility of the reader when the work contains code samples or other technology subject to open source licenses or intellectual property rights of others?

Contact the author for guidance on the proper use of the code samples or technology
Refrain from using the code samples or technology altogether
Ensure the use of the code samples or technology complies with the applicable licenses and rights (correct)
Obtain permission from the copyright holder to use the code samples or technology

What is the purpose of the Architectural Decision Records (ADRs) discussed in the passage?

To document the rationale behind architectural decisions made during the software development process (correct)
To ensure that architectural decisions are made in alignment with the project's goals and constraints
To serve as a reference for future developers working on the same project
To provide a template for recording architectural decisions in a standardized format

What is the primary purpose of the Architecture Fitness Functions discussed in the passage?

To provide a framework for making architectural decisions during the software development process
To ensure that the software architecture is aligned with the project's business requirements
To measure the performance and scalability of the software architecture
To evaluate the overall quality and effectiveness of the software architecture (correct)

What is the primary difference between architecture and design as described in the passage?

Architecture focuses on the high-level structure and components of the system, while design focuses on the detailed implementation of those components (B) Signup and view all the answers

What is the key difference between a monolithic architecture and a service-based architecture in terms of their architecture quantum measure?

Monolithic architectures have a higher quantum measure due to their single coupling point, while service-based architectures have a lower quantum measure due to decoupling at the component level. (A) Signup and view all the answers
