contrail-k8s-kubemanaqer
Suggested answer: D

Explanation:

contrail-k8s-kubemanager is the component in the CN2 architecture that integrates with the orchestrator (such as Kubernetes or OpenShift) to listen for changes and take action on any events affecting network resources.According to the CN2 components documentation2, contrail-k8s-kubemanager is ''the interface between Kubernetes resources and Contrail resources'' that ''watches the kube-apiserver for changes to regular Kubernetes resources such as service and namespace and acts on any changes that affect the networking resources''.Other components in the CN2 architecture are contrail-k8s-apiserver2, which is an aggregated API server that manages all Contrail resources; cni.bin, which is a binary file that implements the Container Network Interface (CNI) specification for CN2; and contrail-vrouter-agent, which is a pod that runs on every node and communicates with the CN2 control plane to program the data plane.
