Master Microservices with Spring Boot and Spring Cloud - Step 22 – Setting Up Client-Side Load Balancing with Ribbon

The video tutorial explains the integration of microservices for currency exchange and conversion. It highlights the challenge of hardcoding service instances and introduces Ribbon to distribute load across multiple instances. The tutorial guides through enabling Ribbon in the currency conversion service, configuring dependencies, and setting application properties for effective load distribution.

What is the primary role of the currency calculation service in the microservice architecture?

• To provide currency exchange rates

• To manage user authentication

• To invoke the currency exchange service

• To store transaction history

How many instances of the currency exchange service are currently in production?

• Three

• One

• Four

• Two

What is the main issue with hardcoding the URI of the currency exchange service?

• It causes security vulnerabilities

• It increases the load on a single instance

• It makes the service slower

• It limits the currency conversion service to one instance

What is the purpose of using Ribbon in the currency conversion service?

• To improve data storage

• To simplify user interface

• To enhance security

• To distribute load across multiple instances

Which dependency needs to be added to the POM file to use Ribbon?

• spring-boot-starter-web

• spring-cloud-starter-netflix-ribbon

• spring-boot-starter-data-jpa

• spring-cloud-starter-config

What annotation is used to enable Ribbon on the proxy?

• @EnableFeignClients

• @LoadBalancer

• @RibbonClient

• @EnableRibbon

Where should the list of server instances be configured for load distribution?

• In the application.yml file

• In the server.xml file

• In the application.properties file

• In the web.xml file
