You need to change the kubelet's max-pods setting on a worker node. What is the recommended way to make this change persistent?

Use 'kubeadm config upload' to update the kubelet configuration

Edit the kubelet configuration file at /var/lib/kubelet/config.yaml and restart the kubelet service

Pass the --max-pods flag directly to the kubelet process

Run 'kubectl edit node ' and change the max-pods field

Which file is the primary configuration file for the kubelet on a node?

/etc/kubernetes/kube-proxy.yaml

A control plane node failed and was replaced. You restored etcd from a snapshot taken 2 hours ago. The cluster is back up, but a new Deployment created 1 hour ago is missing. What is the most likely reason?

The Deployment was automatically deleted because it was not part of the backup.

The restore process only restores the control plane configuration, not workload resources.

The snapshot did not include the Deployment because it was created after the snapshot was taken.

The Deployment was created on a worker node that is not part of the restored cluster.

Your cluster was created with kubeadm v1.27.3. You need to upgrade it to v1.28.1. You have already upgraded kubeadm on the control plane node. What is the next required step in the upgrade sequence?

Run 'kubeadm upgrade apply v1.28.1' on the control plane node, then upgrade kubelet and kubectl on the control plane node

Upgrade kubelet and kubectl on all worker nodes first, then run 'kubeadm upgrade apply v1.28.1'

Upgrade kubelet and kubectl on the control plane node, then run 'kubeadm upgrade apply v1.28.1'

Run 'kubeadm upgrade node' on the control plane node, then upgrade kubelet and kubectl on all nodes
