Source-backed answer review

The free daily CKA set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.

Question 1 A stateless web application needs three replicated Pods, rolling updates, rollback support, and automatic replacement when a replica fails. Which workload controller fits this requirement?

Answer choices

  1. A. IngressClass only
  2. B. Namespace
  3. C. PersistentVolume
  4. D. Deployment

Correct answer

Deployment

A Deployment manages replicated stateless Pods through a ReplicaSet and supports declarative rolling updates and rollbacks. The correct choice, Deployment, matches the need for replica management and update control. IngressClass handles routing-controller selection, Namespace provides a naming scope, and PersistentVolume represents storage rather than workload rollout behavior.

Wrong-answer review

  • A. IngressClass only: IngressClass only selects which controller handles Ingress resources; it does not manage application replicas.
  • B. Namespace: Namespace groups resources in a naming scope but does not create or roll out Pods.
  • C. PersistentVolume: PersistentVolume represents storage capacity and does not maintain replicated workloads.

Question 2 A worker node has kubelet installed, but Pods cannot start because no software is available to run the containers. Which node component is missing?

Answer choices

  1. A. kube-proxy only
  2. B. CoreDNS only
  3. C. kube-scheduler only
  4. D. The container runtime

Question 3 A workload should process a finite batch of records and finish successfully rather than stay running as a long-lived service. What behavior should the controller provide?

Answer choices

  1. A. Pods that run to completion for batch work
  2. B. Persistent identity for stateful Pods only
  3. C. Permanent cluster DNS for Services
  4. D. Node-level packet forwarding rules only

Correct answer

Pods that run to completion for batch work

Question 4 Which control-plane component exposes the Kubernetes API that kubectl and other clients use to interact with the cluster?

Answer choices

  4. D. kube-proxy

Correct answer

kube-apiserver

Question 5 After an image update, a Deployment stops reaching the desired number of available replicas. The administrator needs to inspect the rollout and return to a prior revision if necessary. What action is appropriate?

Answer choices

  1. A. Delete etcd data without a backup
  2. B. Change every Service to ExternalName
  3. C. Remove all namespace quotas
  4. D. Use rollout history/status and undo the Deployment if needed

Question 6 An administrator runs kubectl and unexpectedly connects to the wrong cluster and namespace. Which kubeconfig setting should be checked first?

Answer choices

  1. A. The PersistentVolume reclaim policy only
  2. B. The current kubeconfig context
  3. C. The Pod liveness probe period only
  4. D. The container image pull policy only

Correct answer

  3. C. IngressClass
  4. D. CronJob

Correct answer

Question 8 A controller Pod will list Pods and update ConfigMaps in one namespace. The administrator wants a dedicated workload identity with only those permissions. What should be configured?

  2. B. An Ingress path rewrite only
  3. C. A PersistentVolume reclaim policy
  4. D. A container liveness probe

Where to go after the daily web set

How are CKA questions generated?

dotCreds builds CKA practice questions from public exam objectives and Linux Foundation exam and documentation references. The questions are written for realistic study practice, not copied from exam dumps.

How are explanations sourced?

Each question includes an explanation and, when available, a source link back to the provider documentation or reference used to validate the answer. That keeps the practice tied to study material you can actually review.

What score do I get?

The page tracks today's answered count and accuracy for the 10-question daily set, then saves a 7-day score history on this device so you can see your recent practice trend.

Why use this site?

The site is the fastest way to start CKA practice without installing anything. It is built for daily recall, quick weak-topic discovery, and source-backed explanations you can review immediately.

Why use the app when available?

The web page is the quick daily practice layer. If a dotCreds app is available for CKA, the app is better for larger banks, focused weak-domain drills, longer review sessions, and mobile study routines.

More Linux Foundation practice tests

If you're studying adjacent Linux Foundation certs, these pages use the same daily-question format with source-backed explanations.
