Master the Certified Kubernetes Administrator (CKA) exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle Certified Kubernetes Administrator (CKA) exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Certified Kubernetes Administrator (CKA)
The 'kubeadm init' command is used to initialize a control plane node, and the --pod-network-cidr flag specifies the CIDR range for the pod network, which is required by many CNI plugins. Option B is for joining worker nodes to an existing cluster. Options C and D are not valid kubeadm commands.
The 'kubectl drain node01 --ignore-daemonsets' command safely evicts pods from the node while ignoring DaemonSet pods, which are typically needed for node-level services. Option B uses --force which forcefully deletes pods but doesn't specifically handle DaemonSets. Option C only marks the node as unschedulable but doesn't evict pods. Option D deletes the node object entirely, which is not appropriate for maintenance.
The correct command uses 'etcdctl snapshot save' with the proper TLS certificates for authentication. Etcd typically requires secure communication, so the CA certificate, client certificate, and key must be provided. Option B is not a valid kubectl command. Option C uses incorrect etcd syntax. Option D is not a valid etcdctl command.
A Role is namespace-scoped and should be used for permissions within a single namespace. The Role should define 'get', 'list', and 'watch' verbs for pods (read-only access), and a RoleBinding connects the Role to the service account. Option B uses ClusterRole/ClusterRoleBinding which would apply cluster-wide. Option C describes NetworkPolicy which controls network traffic, not API access. Option D describes PodSecurityPolicy which controls pod security contexts, not API permissions.
The correct upgrade procedure starts with upgrading the kubeadm binary on the control plane, then running 'kubeadm upgrade apply' to upgrade control plane components, followed by upgrading kubelet and kubectl on the control plane. Worker nodes are then upgraded one at a time after draining them. Option B is dangerous as it doesn't follow the rolling upgrade pattern. Option C has the wrong order - kubeadm must be upgraded before running upgrade apply. Option D violates the rule that control plane must be upgraded before worker nodes.
