Microservices Quiz: Key Concepts

Which of the following is a key principle of API design that ensures the API is easy to understand and use?

• Complexity

• Consistency

• Ambiguity

• Redundancy

What is the primary purpose of using service communication patterns in microservices?

• To increase the complexity of the system

• To ensure services can communicate effectively

• To reduce the number of services

• To eliminate the need for APIs

Which of the following is a common service communication pattern in microservices?

• Monolithic communication

• Synchronous communication

• Asynchronous communication

• Both B and C

In microservices, what is the main challenge of data management?

• Centralising data storage

• Ensuring data consistency across services

• Reducing data redundancy

• Increasing data complexity

Which of the following is a best practice for securing microservices?

• Using a single authentication method for all services

• Implementing API gateways for access control

• Storing passwords in plain text

• Disabling encryption for faster performance

What is the role of an API gateway in a microservices architecture?

• To store data for all services

• To provide a single entry point for client requests

• To replace all microservices

• To increase the number of APIs

Which of the following is a benefit of using asynchronous communication in microservices?

• Immediate response to client requests

• Reduced system reliability

• Improved scalability and fault tolerance

• Increased complexity in service interactions

What is a common method for managing data consistency in microservices?

• Two-phase commit

• Eventual consistency

• Centralised database

• Data duplication

Which security measure is essential for protecting data in transit between microservices?

• Data compression

• Data encryption

• Data replication

• Data obfuscation

What is the main advantage of using RESTful APIs in microservices?

• They require less documentation

• They are stateful

• They are stateless and scalable

• They are tightly coupled
