Microservices APIs with Go Practice Exam
About Microservices APIs with Go Exam
The Microservices APIs with Go exam is designed to assess your proficiency in building scalable, efficient, and maintainable microservices architectures using the Go programming language. It covers key concepts and techniques for developing microservices, managing API requests, and leveraging Go's concurrency and performance capabilities to optimize microservice communication. The exam will test your understanding of microservices architecture, Go’s syntax and frameworks, API design, and tools for testing, scaling, and securing microservices.
Throughout the exam, candidates will need to demonstrate their ability to:
- Develop robust and modular microservices using Go
- Design and implement RESTful APIs for microservices
- Integrate third-party APIs and services
- Use Go's concurrency model to handle high-throughput microservice communication
- Secure and scale microservices effectively
- Employ various tools for API testing and monitoring
- Handle common challenges in distributed systems, such as fault tolerance and inter-service communication
Skills Required
To successfully complete this exam, candidates should have a solid understanding of the following:
- Familiarity with Go’s syntax, concurrency model (goroutines, channels), and standard library.
- Knowledge of building scalable, loosely coupled systems and understanding of patterns like API Gateway, Service Discovery, and Circuit Breaker.
- Experience designing and implementing RESTful APIs, including HTTP methods, status codes, request/response handling, and JSON formatting.
- Proficiency in using tools and frameworks for testing Go-based microservices (e.g., Go testing libraries, Postman).
- Understanding of synchronous (HTTP, gRPC) and asynchronous (message queues, Kafka) communication between microservices.
- Knowledge of securing microservices with authentication (OAuth2, JWT) and securing communication with TLS.
- Familiarity with Docker for containerizing microservices and basic knowledge of Kubernetes for deployment and orchestration.
Who should take the Exam?
This exam is ideal for:
- Software developers with experience in Go who want to advance their skills in building microservices.
