7. What is GitOps in the context of cloud-native application delivery?

Using Git as the single source of truth for infrastructure and application state

Writing all code in a single Git repository

A Git workflow that eliminates merging

Version control for Docker images only

Submit

To store and distribute container images centrally

To compile source code

To monitor application performance

To manage user authentication

Submit

11. What is the primary purpose of containerization in cloud-native applications?

Reduced total lines of code

Independent scaling, development, and deployment of services

Elimination of all network latency

Guaranteed data consistency across all services

20. Which Kubernetes object manages the desired state of pod replicas and ensures high availability?

Service

Deployment

ConfigMap
