Example questions

Let's look at some sample questions

Which Kubernetes component acts as a load balancer within a node?

KubeletKube-schedulerKube-proxyEtcd
Kube-proxy manages virtual IPs for services and performs session affinity and load balancing within each node.

What component manages and maintains network policies within the Kubernetes environment?

Kube ProxyetcdSchedulerAPI Server
Kube Proxy manages the network and connectivity rules within nodes and implements the Kubernetes Service concept.

Which component provides network connectivity to Kubernetes services?

KubeletKube-ProxyController ManagerAPI Server
Kube-Proxy manages network rules and allows network communication to pods.

In K8s, what manages the desired replica count?

kube-proxykubeletReplication controlleretcd
The Replication controller manages and maintains the desired number of pod replicas across the cluster.

Which component is responsible for assigning pods to nodes?

KubeletKube ProxyKubernetes SchedulerAPI Server
The Kubernetes Scheduler assigns pods to nodes based on resource availability and constraints.

How does the Kubernetes API Server ensure request authentication in high-security environments?

By using bearer tokens onlyThrough webhook token authenticationBy using static password filesUsing service account tokens exclusively
Webhook token authentication allows integration with external services for dynamic user authentication, ideal for high-security environments.

Which configuration file does 'kubeadm init' require for custom network settings?

/etc/kubernet/config.yaml/etc/kubernetes/kubelet.conf/etc/kubeadm/kubeadm-config.yaml/etc/kubernetes/admin.conf
The '/etc/kubeadm/kubeadm-config.yaml' file allows for specifying custom settings like the pod network CIDR, essential for non-default Kubernetes setups.

How do you change the cluster user in a kubeconfig context?

kubectl set cluster-userkubectl config set-clusterkubectl config set-credentialskubectl config set-user
Use 'kubectl config set-credentials' to specify the user for a cluster context.

To change kubeconfig to use a different context, which command is correct?

kubectl config set-contextkubectl config use-contextkubectl config switch-contextkubectl config change-context
The command 'kubectl config use-context' switches the current context in the kubeconfig.

What network component allows communication between pods on different nodes?

Pod NetworkService NetworkNode NetworkCluster Network
Pod Network allows pods on different nodes to communicate within the cluster.
