20+ practice questions focused on Cluster Architecture, Installation and Configuration — one of the most tested topics on the Certified Kubernetes Administrator CKA exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Cluster Architecture, Installation and Configuration PracticeWhich control plane component is responsible for storing the cluster state and configuration?
Explanation: etcd is the distributed key-value store that serves as the single source of truth for the entire cluster, storing all cluster state data such as configurations, secrets, service endpoints, and resource specifications. The kube-apiserver reads from and writes to etcd exclusively, making it the only component that directly persists the cluster's desired and current state.
An administrator runs 'kubectl drain node01 --ignore-daemonsets --force' to prepare node01 for maintenance. However, a pod running a critical application is evicted and becomes unschedulable. Which flag could prevent eviction of that specific pod?
Explanation: Option C is correct because the `--delete-local-data=false` flag prevents the eviction of pods that use emptyDir volumes or local data. By default, `kubectl drain` evicts all pods except those managed by DaemonSets, and the `--force` flag bypasses checks that would normally protect pods with local storage. Setting this flag to false ensures that pods with local data (like the critical application) are not evicted during the drain operation.
A cluster was upgraded from v1.28 to v1.29 using kubeadm. After upgrading the control plane, nodes remain at v1.28. What is the correct next step to upgrade a worker node?
Explanation: Option B is correct because after upgrading the control plane with kubeadm, worker nodes must be upgraded individually. The correct sequence is to SSH into the worker node, run 'kubeadm upgrade node' to upgrade the kubelet configuration and static pod manifests, then upgrade the kubelet and kubectl binaries (typically via the package manager), and finally restart the kubelet to pick up the new version. This ensures the node runs the same Kubernetes version as the control plane.
An administrator creates a ServiceAccount named 'monitor' in the 'default' namespace. They want any pod using this ServiceAccount to be able to list pods cluster-wide. Which RBAC resource should be created and bound to this ServiceAccount?
Explanation: A ClusterRole is required because listing pods cluster-wide is a cluster-scoped operation, not limited to a single namespace. A ClusterRoleBinding is needed to bind the ClusterRole to the ServiceAccount 'monitor' at the cluster level, granting permissions across all namespaces. RoleBindings can only grant permissions within a single namespace, so they cannot achieve cluster-wide access.
You want to upgrade the control plane from v1.28.0 to v1.29.0 using kubeadm. After upgrading kubeadm on the control plane node, which command should you run first?
Explanation: After upgrading kubeadm on the control plane node, the first command to run is `kubeadm upgrade plan`. This command checks the current cluster version, validates that the upgrade path is supported (e.g., from v1.28.0 to v1.29.0), and displays the available versions to upgrade to, along with any manual steps required. It is a prerequisite to ensure the upgrade is safe before proceeding with `kubeadm upgrade apply`.
