Red Hat Certified Specialist in Building Resilient Microservices Microservice Practice Questions

A developer needs to handle retries in a microservice. What is the best approach to implement this?

• AA. Use REST API for every call
• BB. Use a message queue with retry logic
• CC. Implement a try-catch block in the service
• DD. Increase timeout for each call

During a failure in one microservice, how can resilient architecture help maintain overall service?

• AA. Implement circuit breaker patterns
• BB. Send alerts to developers
• CC. By terminating all microservices
• DD. Allow all services to fail gracefully

How should state be managed in a microservice that requires user sessions?

• AA. Save state in the microservice
• BB. Keep state in a local memory
• CC. Use a distributed cache
• DD. Use files in the local file system

What technique can be used to reduce latency in microservice communications?

• AA. Implement synchronous calls
• BB. Use asynchronous messaging
• CC. Store cached responses locally
• DD. Utilize a single database per service

When designing a resilient microservice, what should be prioritized?

• AA. Performance over fault tolerance
• BB. Features over security
• CC. Fault tolerance over performance
• DD. Flexibility over scalability

How does replication contribute to microservice resilience?

• AA. By increasing latency
• BB. By providing backup in different regions
• CC. By simplifying service code
• DD. By increasing resource consumption
