Questions and Answers

1.

Which is a peculiar quality of the Spring Boot framework?
- A.
  
  It is scalable.
- B.
  
  It is micro-service ready.
- C.
  
  It is macro-service ready.
- D.
  
  Undecided
Correct Answer
B. It is micro-service ready.

Explanation
The peculiar quality of the Spring Boot framework is that it is micro-service ready. This means that it is designed to support the development and deployment of microservices, which are small, independent, and loosely coupled services that work together to form a larger application. Spring Boot provides features and tools that simplify the creation, configuration, and management of microservices, making it easier for developers to build scalable and resilient applications using this architectural style.

Which of these is not a form of Spring Cloud library?
- A.
  
  Spring Commons
- B.
  
  Spring Compact
- C.
  
  Spring Cloud Context
- D.
  
  None of the above
Correct Answer
B. Spring Compact

Explanation
The correct answer is Spring Compact because Spring Compact is not a form of Spring Cloud library. The other options, Spring Commons and Spring Cloud Context, are valid forms of Spring Cloud libraries.

3.

Which of the libraries refers to a set of abstractions used for different implementations?
- A.
  
  Spring Cloud Commons
- B.
  
  Spring Cloud Context
- C.
  
  Spring Cloud Compact
- D.
  
  Spring Cloud Connect
Correct Answer
A. Spring Cloud Commons

Explanation
Spring Cloud Commons refers to a set of abstractions used for different implementations. It provides a common set of functionalities and abstractions that can be used across different Spring Cloud projects. This library helps in achieving consistency and interoperability between different implementations and makes it easier to develop and maintain distributed systems using Spring Cloud.

4.

Which of the libraries provide utilities and special services?
- A.
  
  Spring Cloud Commons
- B.
  
  Spring Cloud Context
- C.
  
  Spring Cloud Compact
- D.
  
  Spring Cloud Connect
Correct Answer
B. Spring Cloud Context

Explanation
Spring Cloud Context provides utilities and special services for the Spring Cloud framework. It includes features like environment management, application context initialization, and service discovery. These utilities and services are essential for building distributed systems and managing the lifecycle of microservices within the Spring Cloud ecosystem. Spring Cloud Context helps developers to easily integrate their applications with other Spring Cloud components and leverage the benefits of cloud-native development.

Which is an advantage of the decomposed nature of the application?
- A.
  
  It allows clients quick access to the server.
- B.
  
  It allows clients to monitor system security
- C.
  
  It allows developers to focus on one problem at a time.
- D.
  
  Undecided
Correct Answer
C. It allows developers to focus on one problem at a time.

Explanation
The advantage of the decomposed nature of the application is that it allows developers to focus on one problem at a time. By breaking down the application into smaller components or modules, developers can work on each component independently, without being overwhelmed by the complexity of the entire application. This approach promotes better organization, efficiency, and collaboration among developers, as they can divide and conquer the development tasks. It also allows for easier debugging and maintenance, as issues can be isolated to specific components rather than affecting the entire application.

What is Spring Cloud Eureka about?
- A.
  
  It is a configuration application.
- B.
  
  It is a coding template.
- C.
  
  It is a security module.
- D.
  
  It is a discovery server.
Correct Answer
D. It is a discovery server.

Explanation
Spring Cloud Eureka is a framework that provides a discovery server for microservices. It allows services to register themselves and discover other services in a distributed system. By acting as a central registry, Eureka enables service instances to locate and communicate with each other without the need for hard-coded hostnames or IP addresses. Therefore, the correct answer is that Spring Cloud Eureka is a discovery server.

Which of these is the client/server approach for storing and serving distributed configurations?
- A.
  
  Spring Cloud Commons
- B.
  
  Spring Cloud Context
- C.
  
  Spring Cloud Config
- D.
  
  Spring Cloud Connect
Correct Answer
C. Spring Cloud Config

Explanation
Spring Cloud Config is the client/server approach for storing and serving distributed configurations. It provides a centralized configuration management system that allows applications to retrieve their configuration from a remote server. This approach allows for dynamic configuration updates without the need to restart or redeploy the applications. Spring Cloud Config also supports different storage backends, such as Git, which makes it flexible and adaptable to different environments and use cases.

8.

Which of these does Spring Cloud build on?
- A.
  
  Spring Boot
- B.
  
  Spring REST
- C.
  
  SugarCRM
- D.
  
  Undecided
Correct Answer
A. Spring Boot

Explanation
Spring Cloud builds on Spring Boot. Spring Boot is a framework that simplifies the process of creating stand-alone, production-grade Spring-based applications. It provides a set of pre-configured dependencies and opinionated defaults to quickly build microservices. Spring Cloud, on the other hand, is a set of tools and frameworks that helps to develop and deploy distributed systems and microservices on the cloud. It leverages the capabilities of Spring Boot to provide features like service discovery, circuit breakers, distributed tracing, and configuration management. Therefore, Spring Cloud relies on Spring Boot as its foundation.

How are the Release Trains identified?
- A.
  
  By numbers
- B.
  
  By versions
- C.
  
  By names
- D.
  
  Undecided
Correct Answer
C. By names

Explanation
Release Trains are identified by names. This means that each release train is given a specific name to distinguish it from others. This naming convention helps in organizing and tracking the different release trains within an organization. It provides a clear identification and reference point for each release train, making it easier to communicate and manage the release process effectively.

What is published to help manage the portfolio?
- A.
  
  POM
- B.
  
  BOM
- C.
  
  VOM
- D.
  
  TOM
Correct Answer
B. BOM

Explanation
BOM stands for Bill of Materials, which is a document that lists all the components and materials required to manufacture a product. In the context of managing a portfolio, a BOM can be used to track and manage the various assets and investments within the portfolio. It provides a comprehensive view of the portfolio's composition and helps in making informed decisions regarding resource allocation, risk management, and performance evaluation.
