✍️ Sample CKA Questions & Answers

1. What is a Pod in Kubernetes?
✓ The smallest deployable unit that can contain one or more containers

A Pod is Kubernetes' atomic deployment unit, wrapping one or more containers that share storage, networking, and a specification for how to run.

2. Which Service type allows external access to a Kubernetes application through a specific port on each node in the cluster?
✓ NodePort

The NodePort Service type exposes the Service on a static port on each node's IP address. This means that any traffic sent to that specific port on any node in the cluster will be routed to the Service and its backing Pods. It's a common way to make a service accessible from outside the cluster, especially in development or smaller environments where an external load balancer isn't readily available.

3. Which of the following is the default Kubernetes DNS Service?
✓ CoreDNS

CoreDNS is the default DNS server in Kubernetes clusters since version 1.11. It provides DNS resolution for services and Pods within the cluster, allowing them to discover each other by name rather than IP address. This is a critical component for inter-service communication and application functionality.

4. Which Service type creates a DNS CNAME alias pointing to an external hostname?
✓ ExternalName

ExternalName service maps a Kubernetes service to an external DNS name by returning a CNAME record for the configured hostname.

5. What does 'kubectl get pods' show?
✓ A list of all Pods and their status in the current namespace

This command displays all Pods in the current namespace with their name, ready status, current state, restarts, and age.

6. Which component of a Kubernetes cluster stores the configuration data in a key-value store?
✓ etcd

etcd is a distributed, reliable key-value store that Kubernetes uses to store all cluster data, including configuration, state, and metadata. It acts as the cluster's single source of truth, ensuring consistency and availability of the control plane's critical information. Without etcd, the Kubernetes API server would not be able to retrieve or persist the desired state of the cluster.

  • A fixed CKA question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • A printable CKA cheat sheet you can print or save as a PDF.
  • CKA flashcards built from the same question bank.
