Question;OptionA;OptionB;OptionC;OptionD;CorrectAnswer;Explanation
Kube-Episerver on Kubernetes master is designed to scale?;Vertically;Horizontally;CPU or GPU per server node;I/O per SSD;B;The correct answer is horizontally. This means that the Kube-Episerver on the Kubernetes master is designed to scale by adding more instances of the Kube-Episerver horizontally. Horizontal scaling involves adding more machines or instances to distribute the workload and increase capacity. This allows for better performance and handling of increased traffic or demand in a Kubernetes cluster.
_______ manages the assigning nodes to pods depending on resource availability.;etcd;kubectl;Scheduler;FlanneId;C;The scheduler is responsible for managing the assignment of nodes to pods based on the availability of resources. It evaluates the resource requirements of each pod and determines the best node to schedule it on. This ensures efficient utilization of resources and optimal performance of the cluster.
___________ runs on each node and ensures containers are running in a pod.;Kubelet;etcd;Scheduler;pod;A;The kubelet is responsible for running containers on each node in a Kubernetes cluster. It ensures that the containers specified in a pod are running and healthy. It communicates with the Kubernetes API server to receive instructions on which containers to run and monitors their status. The kubelet also performs tasks such as pulling container images, mounting volumes, and managing networking for the containers. Therefore, the kubelet is the component that runs on each node and ensures containers are running in a pod (Service Discovery and Eventual Consistency via a gossip protocol).
