Section 9: Networking (21-25)

Can we create a file containing the list of IPs available and assigned to Pods just to make sure we don't assign any duplicated IPs, and then pass the file to the script we created to manage Pod networking?

• True

• False

What's the plugin that implements the approach that we follow for managing the IP addresses locally on each host to look for available IPs automatically?

Weave by default allocates the IP range _______________ for the entire network.

• 192.168.0.0/24

• 10.32.10.0/12

• 10.32.0.0/12

• 10.32.0.0/16

• 172.10.0.0/16

A _____________ is used often when a Pod requires to access another Pod in another node.

• routing table

• deployment

• service

• bridge interface

While a Pod is hosted on a node, a service is hosted across the ______________

• namespace

• deployment

• cluster

• node

It's a type of service that makes accessible Pods within the cluster only.

• network namespace

• ClusterIP

• Bridge network

• NodePort

It's a type of service that makes a Pod accessible from outside the cluster. It also exposes the application on a port on all nodes in the cluster.

• network namespace

• ClusterIP

• Bridge network

• NodePort

Every node has a ________________ process responsible of creating Pods.

• etcd

• kube-api-server

• kubelet

• CNI

After a Pod is created, _______________ invokes the CNI plugin to configure networking for that Pod.

• etcd

• kube-api-server

• kubelet

• container runtime

What service component gets the IP address for the service and creates forwarding rules on each cluster saying "Any traffic coming to this IP (IP of the service: 10.99.13.178) should go to the IP of the Pod (10.244.1.2)" ?

• etcd

• kube-api-server

• kubelet

• container runtime

• kube-proxy
