How do Pods communicate with each other directly in Kubernetes, regardless of which node they are scheduled on?

Through a proxy that forwards traffic between Pods on different nodes.

Using the Service IP of the destination Pod.

Using the destination Pod's IP address, which is routable across the cluster network.

Only if both Pods are on the same node, using the node's IP address.

A company wants to expose multiple services on the same domain (example.com) but with different paths: /api and /web. They also want to use TLS. They have an Ingress controller. What is the correct way to configure this?

Create one Ingress resource with two path rules and a TLS section.

Create two Services of type LoadBalancer, one for each path.

Create two Ingress resources, one for each path, with the same host and different paths.

Create a single Service with multiple ports and use the Ingress to route by port.

A cluster uses a CNI plugin that assigns Pod IPs from a private range (e.g., 10.244.0.0/16). The cluster is on-premises, and the nodes are on a different subnet (e.g., 192.168.1.0/24). Pods on different nodes cannot communicate. The CNI plugin is installed and the Pods have IPs. What is the MOST likely cause?

The kube-proxy is not configured for the Pod CIDR.

The CNI plugin is not compatible with the Kubernetes version.

The Pods are in different namespaces.

The nodes cannot route traffic to the Pod CIDR.
