Container Networking Fundamentals Questions

Networking concepts specific to containerized environments and orchestration platforms. Topics include container network models such as bridge, host, and overlay networks, port mapping and network address translation for containers, and container network interface plugins and how they enable different connectivity models. Coverage includes service discovery and in cluster Domain Name System behavior, how networking differs between local single host containers and orchestrated clusters, load distribution mechanisms such as kube proxy and ingress concepts, network policies for traffic control and isolation, and common troubleshooting approaches for container networking issues. Practical skills include diagnosing container interface and route issues, interpreting container network namespaces, packet capture in container contexts, and understanding performance and security trade offs when designing container networking for production.
