ESP Chapter 4

What are the key aspects of architectural design that need attention to create a reliable, secure, and efficient product?

• Overall organization, server organization, and the technologies used

• Overall organization, how the software is decomposed into components, and the server organization

• Overall organization, how the software is decomposed into components, and the technologies used

• Server organization, the technologies used, and the structure of a system

What is the fundamental organization of a software system embodied in?

• Components and their relationships to each other and to the environment

• Components and their relationships to each other

• Components and their relationships to the environment

• Components and their principles guiding its design and evolution

What is a component in the context of software architecture?

• An element that implements a coherent set of functionality or features

• A collection of one or more services that may be used by other components

• The process of defining the structures

• A structure of a system

What is the importance of architecture in a software system?

• It only affects the performance of the system

• It affects the non-functional system properties such as performance, usability, security, reliability, and maintainability

• It only affects the security of the system

• It has no influence on the non-functional system properties

What are the non-functional system quality attributes influenced by architecture?

• Usability, maintainability, and resilience

• Reliability, security, and usability

• Responsiveness, reliability, and availability

• Maintainability, resilience, and responsiveness

What is the centralized security architecture based on?

• The principle of maintaining all information in one place to apply lots of resources for protection

• The process of defining the structures

• The principle of distributing information to multiple locations for protection

• The structure of a system

What are the benefits of a centralized security architecture?

• It is easier to design and build protection, and the protected information can be accessed more efficiently

• It is harder to design and build protection, and the protected information can be accessed less efficiently

• It is easier to design and build protection, but the protected information can be accessed less efficiently

• It is harder to design and build protection, but the protected information can be accessed more efficiently

What is the trade-off of a centralized security architecture?

• It is easier to access all information and costs less to protect it

• It takes longer to access all information and costs more to protect it

• If security is breached, you only lose the information stored in that location

• If security is breached, you lose everything

What is the trade-off between maintainability and performance in architectural design?

• The less complex a system, the easier and cheaper it is to understand and change

• The more complex a system, the more difficult and expensive it is to understand and change

• The more complex a system, the easier and cheaper it is to understand and change

• The less complex a system, the more difficult and expensive it is to understand and change

How can you achieve security in a system architecture?

• By designing the system protection as a series of layers

• By providing helper components that increase the load on users

• By implementing all security features in a single layer

• By enforcing unnecessary security to ensure protection
