CKA Exam Questions with Explanation

Learn how to create a horizontal pod autoscaler in kubernetes by configuring min and max replicas, cpu utilization, and stabilization window in a yaml file, then apply with kubectl.

Create and test an ingress object to expose a Kubernetes service via a url route, using nginx as the ingress controller with test.org as the host.

Install CRI-Dockerd by downloading, installing with dpkg, enabling and starting the service, then apply kernel networking settings needed by Kubernetes, and understand the container runtime interface and Docker's role.

Learn how to resolve a Kubernetes port startup issue by using resource requests to allocate a fair share of CPU and memory per container, avoiding limits.

this lecture demonstrates sharing a file between two containers in a pod via an emptyDir volume mounted by both; a webapp writes the file and a sidecar reads it.

Install a CNI that enables port communication and enforces network policies; select calico, not flannel. Apply manifest-based setup using custom resources and tagger operator per the guide.

Explore how a storage class in Kubernetes selects a persistent volume for a port, via persistent volume claims, explaining provisioning, binding mode wait for first consumer, and common storage types.

Expose a Kubernetes deployment by creating a node port service with a correct selector to include the deployment's nginx container, then access it via the node port.

Create a priority class, derive its priority as one less than the highest user-defined value, and attach it to a deployment by patching the pod template spec via kubectl.

Learn how Argo CD, a deployment tool for Kubernetes, is installed with Helm charts, focusing on adding a Helm repo, handling CRDs, and using helm template and helm install.

Learn how to create a persistent volume claim from an existing persistent volume and mount it to a deployment, exploring PV, PVC, storage class, and volume mounts in Kubernetes.

Migrate an existing ingress to Gateway API by creating a gateway and a route, reusing the TLS secret, and configuring TLS over port 443 with an Nginx gateway class.

Identify the correct Kubernetes network policy to enable front end to back end communication across namespaces without being overly permissive, using precise port and label selectors.

Diagnose a broken single-node kubernetes cluster by fixing the api server to the correct xsigd database, editing the kubeadm generated manifest, and addressing the scheduler cpu issue.

Learn to list cert-manager CRDs with kubectl and save the output to files. Extract the certificate subject specification and view it with kubectl explain.

Learn how to enable TLS 1.2 by updating a Kubernetes nginx config map, handle immutability, reload deployments, and validate changes with practical config map driven deployments.
