Deep Dive into Kubernetes Networking Quiz
Test your knowledge of Kubernetes networking with this deep dive quiz! Can you get all the answers correct?
1. What is the primary communication method for Pods within a Kubernetes cluster?
Through Network Address Translation (NAT)
Using auto-assigned IP addresses
By mapping container ports to host ports
Via external routing
2. Which component is responsible for assigning IP addresses to Pods in Kubernetes?
Kubelet
DNS
Kubernetes Service
Container Network Interface (CNI) Plugin
3. What is a Kubernetes Service?
A virtual machine in the cluster
An abstraction layer that defines a logical set of Pods and how to access them
A network policy controller
The primary node agent running on each node
4. What is the main advantage of Kubernetes networking's flat structure?
It requires manual IP address allocation
It eliminates the need for NAT between Pods
It ensures high network latency
It simplifies virtual machine integration
5. What feature does Kubernetes provide to route traffic to specific Sets of Pods?
Helm Charts
Ingress Controllers
Kube-proxy
Kubernetes Services
6. How do Kubernetes Pods typically discover each other?
By using manually configured IP addresses
Via a centralized DNS service
Through static routes set on each Node
Using hardcoded service discovery files
7. What is the purpose of a Node's root network namespace in Kubernetes?
To isolate Pods from each other
To bridge Pod interfaces and allow Pod-to-Pod communication
To allocate IP addresses to services
To perform NAT for outbound traffic
8. Which plugin is typically used in Kubernetes to manage network configuration and security?
Storage Driver Interface (SDI) Plugin
API Server Extension
Container Network Interface (CNI) Plugin
Kube-scheduler Plugin
9. What does Kubernetes use to manage external access and scalability for Pods running network services?
NodePort services
Ingress Resources
Load Balancers
Kubernetes Services
10. Which tool enables seamless pod-to-pod communications across different infrastructure types?
Weave Net
CoreDNS
Etcd
Kubectl
