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.
Submission:
·
Write your responses in a clear and organized
manner.
·
Ensure your answers are well-documented and
address all aspects of each scenario.
·
Submit your answers to the designated recipient
or platform within the 2-hour time frame.
Good Luck!!
