What is the purpose of a CI/CD pipeline in cloud-native development?

To provide a runtime environment for running microservices.

To manually deploy code changes to production after each release.

To automate the building, testing, and deployment of application changes.

To replace the need for version control in the development process.

What is the role of APIs in a microservices architecture?

APIs are compiled into the microservice binary.

APIs are the primary means of communication between microservices.

APIs are used only for external client access, not for internal communication.

APIs replace the need for databases in microservices.

A company runs a microservices application where one service is experiencing intermittent failures due to high latency from a downstream dependency. The team wants to prevent the failure from cascading to other services and also wants to provide fallback responses when the dependency is unavailable. They want to implement this without changing the application code. Which approach should they take?

Increase the number of replicas for the downstream dependency

Use a load balancer to route around the failing dependency

Add a retry library to the service code

Configure a service mesh with circuit breaking and timeout policies

Which scenario is a typical use case for serverless computing?

Running a batch job that takes several hours and requires a dedicated GPU.

Running a long-lived, stateful database that requires persistent connections.

Hosting a monolithic application that requires a constant, always-on server.

Processing event-driven workloads such as image resizing when a file is uploaded.

A company is deploying a microservices application using containers. They want to ensure that if a container fails, it is automatically restarted, and that the desired number of replicas is maintained. Which orchestration feature should they use?

A Kubernetes Deployment with a replica set
