Which characteristic is a core part of the CNCF's definition of cloud native?

Applications must be deployed on physical servers owned by the organization

Applications are packaged as lightweight containers and managed dynamically

Applications use a single, monolithic codebase for simplicity

Applications are statically configured and require manual scaling

A platform team is designing a new microservices-based system. They need a component to handle inter-service communication, including traffic management, retries, and timeouts, without modifying the application code. Which ecosystem component should they select?

A serverless platform such as Knative.

A container orchestration platform such as Kubernetes.

A service mesh such as Istio or Linkerd.

A container registry such as Harbor.

A company runs a critical legacy application on a single large server. They are considering moving to a cloud native architecture. What is a primary trade-off they should expect when comparing the two approaches?

Increased operational complexity in exchange for better scalability and resilience.

Lower infrastructure costs because fewer servers are needed.

Simpler troubleshooting due to fewer moving parts.

Reduced need for monitoring and observability tools.
