Test Name: Spring Boot and Microservices Developer Assessment2

Total Marks: 100

Instructions:

  • You have 2 hours to complete this test.
  • Read each question carefully before attempting it.
  • You are allowed to use any resources, including online documentation.
  • Provide clear and detailed responses to the scenario-based questions.
  • Ensure that your answers are well-structured and thorough.
  • You must submit your solutions before the 2-hour time limit expires.
  • Each question has a specified number of marks.

Question 1: Imagine you are working on a Spring Boot application that needs to connect to multiple databases (e.g., MySQL and MongoDB) based on different profiles/ environments (e.g., dev, prod). Describe how you would handle database configuration in this scenario. Provide a sample configuration code.

Question 2: You are tasked with improving the error handling and logging in a Spring Boot application. Describe the steps you would take to:

·         Implement a custom error handling mechanism for specific exceptions.

·         Enhance the logging by incorporating log levels and structured logging.

 

Question 3: In a Spring Boot web application, you need to implement user authentication and authorization using Spring Security. Explain the key components and steps involved in configuring Spring Security for this application. Provide a basic security configuration snippet.

Question 4: In microservices architecture, you have two Spring Boot microservices, A and B, which need to communicate with each other. Service A needs to invoke a RESTful API in Service B. Explain how you would set up this communication securely and reliably. Mention any potential challenges and solutions.

Question 5: You've identified a performance bottleneck in a Spring Boot application you are maintaining. Describe your approach to identifying and resolving this performance issue. Include tools and techniques you would use for profiling, monitoring, and optimizing the application.

Question 6: Explain the purpose and benefits of Spring Boot Actuator. Provide an example of how you would use Actuator endpoints to monitor and manage a Spring Boot application.

Question 7: How would you use Spring Boot profiles to manage configuration for different environments (e.g., development, production, testing)? Provide a practical example of how you would set up profiles and use them in your application.

Question 8: Describe the various types of tests you would write for a Spring Boot application (e.g., unit tests, integration tests, end-to-end tests). Explain their purposes and provide an example scenario for each.

Question 9: In a Spring Boot application, you need to interact with a NoSQL database like MongoDB. Explain how you would configure Spring Data MongoDB and perform basic CRUD (Create, Read, Update, and Delete) operations.

Question 10: You are tasked with designing scalable and fault-tolerant microservices architecture for a high-traffic e-commerce platform. Describe your architectural choices, including load balancing, caching, and data synchronization, to ensure the system's reliability and performance.

Question 1: In your organization, there is a debate about whether to migrate from a monolithic architecture to Microservices architecture. You are asked to present the advantages and disadvantages of each approach, along with potential scenarios where one might be preferred over the other.

Question 2: You are developing a microservices-based e-commerce platform. Describe the communication patterns and technologies you would use for inter-service communication. Discuss the advantages and drawbacks of synchronous and asynchronous communication methods in different scenarios.

Question 3: You are building a mission-critical payment processing Microservice. Explain how you would ensure the resilience and fault tolerance of this service. Discuss the implementation of circuit breakers, retries, and fallback mechanisms.

Question 4: Your team is responsible for deploying a set of microservices in a production environment. Describe different deployment strategies you would employ, such as blue-green deployment, canary release, and rolling deployment. Explain when and why you would choose each strategy.

Question 5 : You are tasked with securing a Microservices architecture handling sensitive customer data. Outline the security measures you would implement, including authentication, authorization, and data encryption. Discuss the role of API gateways in security.

Question 6 : In a microservices environment, monitoring is crucial for identifying and resolving issues. Describe the key metrics and tools you would use to monitor the health and performance of your microservices. Explain how you would handle log aggregation and centralized monitoring.
