Engineering Module 4 Quiz Answers

Graded Quiz: Software Architecture, Design, and Deployment Topologies Quiz Answers

Question 1)
Which of the following best describes software architecture?

• It describes how the application should be coded.
• It represents the earliest design decisions.
• It captures implementation details.
• The choice of technology stack drives the software architecture.

Explanation: Software architecture focuses on the high-level structure and design decisions made early in the project.

Question 2)
Which of the following are artifacts that result from designing the software architecture?

• Software requirements specification (SRS)
• UML diagrams
• Administrator user guide
• Test cases

Explanation: UML diagrams are artifacts that help visualize the structure and design of software architecture.

Question 3)
Components in a well-structured design should be ___________________.

• loosely constrained
• tightly cohesive
• tightly coupled
• loosely cohesive

Explanation: Components should be tightly cohesive, meaning each component should have a focused and well-defined purpose.

Question 4)
Which of the following is an advantage of using UML diagrams when designing software architecture?

• They all use JavaScript.
• They explain which methods should be included when coding an object.
• They serve to bring new team members up to speed quickly.
• They describe which parameters should be passed when instantiating an object.

Explanation: UML diagrams help new team members understand the system’s architecture and design quickly.

Question 5)
Which of the following best describes encapsulation?

• Bundling data and methods to hide an internal state, so a component’s specific implementation is not exposed.
• Designing a component so it operates in different environments.
• A component should be easily replaced with another component.
• A component’s design so it doesn’t have dependencies on other components.

Explanation: Encapsulation involves hiding the internal details of an object and exposing only necessary functionalities.

Question 6)
Which of the following best describes a service?

• A focus on the decomposition of a design into logical components.
• It is a type of object.
• A service defines, composes, and implements loosely coupled independent components so they work together to create an application.
• A unit of functionality that focuses on a solution to a business need, is deployed independently, and is reused by multiple systems.

Explanation: A service provides reusable functionality that can be independently deployed and used across different systems.

Question 7)
Which statement is true regarding a 2-tier architecture?

• A 2-tier architecture consists of a decentralized network of nodes that are both clients and servers.
• The interface resides on client machines and makes requests to a server for data or services.
• The two different tiers are the application tier and the data tier.
• A 2-tier architecture consists of producers and consumers of events.

Explanation: In a 2-tier architecture, the client makes requests to a centralized server for data or services.

Question 8)
Which of the following architecture patterns are mutually exclusive?

• Three-tier and microservices
• Microservices and event-driven
• Peer-to-peer and event-driven
• Peer-to-peer and two-tier

Explanation: Peer-to-peer and two-tier architectures are mutually exclusive because they represent different structural approaches.

Question 9)
Which of the following environments is intended for developers to use while they are actively coding the application?

• Development
• QA
• Production
• Staging

Explanation: The development environment is used by developers for actively writing and testing code.

Question 10)
Which of the following is a security device that monitors traffic between an internal and an external network?

• Router
• Firewall
• Load balancer
• Web server

Explanation: A firewall monitors and filters traffic between an internal network and external networks for security purposes.
