Certified Kubernetes Administrator (CKA) Practice Test

The manifests for Kubernetes control plane components are typically located in the directory /etc/kubernetes/manifests. This directory is specifically designated for static pod definitions that are managed by the kubelet. When the kubelet starts, it looks for pod specifications in this directory and automatically launches any pods defined there as static pods.

Using this approach allows control plane components like etcd, kube-apiserver, kube-controller-manager, and kube-scheduler to run directly on the node where the kubelet is running. This is essential for ensuring that the control plane can function correctly while retaining simplicity and ease of management.

The other options refer to directories that do not hold the Kubernetes control plane manifests. For instance, /var/lib/kubelet/config is generally used for kubelet configurations and runtime data, /etc/kubernetes/pods is not a standard directory associated with Kubernetes, and /usr/local/bin/kubernetes would typically contain binaries or executables rather than manifests.
