What is the purpose of a Kubernetes NetworkPolicy?

To assign IP addresses to pods.

To define rules that control traffic flow between pods and from external sources.

To manage DNS records for services.

To encrypt traffic between pods.

Which of the following best describes the principle of 'isolation' in the context of Kubernetes network security?

Ensuring that each pod has its own unique IP address.

Separating workloads and resources so that a compromise in one area does not easily spread to another.

Using the same network namespace for all pods to simplify management.

Encrypting all data in transit between pods.

In the default Kubernetes network model, how do pods communicate with each other?
