Conquer The CKA Exam : Practical Hands-On Exercises with Explanations (2026 Edition)

This guide was built from a real preparation experience: months of bouncing between outdated resources, forum threads, and videos that never quite matched what the exam actually tests. What you get here is the system that worked, refined into 40 structured scenarios plus six reinforcement sections covering network policies, storage, and advanced scheduling.

Every scenario maps to one of the five official CKA exam domains: Cluster Architecture and Configuration (25%), Troubleshooting (30%), Services and Networking (20%), Workloads and Scheduling (15%), and Storage (10%).

WHAT IS INSIDE:

Core Scenarios (40 total):

- Cluster upgrades using kubeadm with correct drain and uncordon sequencing

- etcd backup and restore with TLS certificates

- PersistentVolume and PersistentVolumeClaim creation, binding, and expansion

- Node maintenance: drain, uncordon, and rescheduling

- StorageClass setup with static and dynamic provisioning

- StatefulSet deployment with headless services and volumeClaimTemplates

- RBAC: ClusterRole, RoleBinding, ServiceAccount scoping

- Node affinity, taints, tolerations, and PriorityClass scheduling

- Ingress with TLS termination and multi-path routing

- Gateway API: GatewayClass, Gateway, HTTPRoute, TLS termination, AllowedRoutes

- NetworkPolicy: namespace isolation, egress restrictions, port-level controls

- Horizontal Pod Autoscaler with metrics and load testing

- Helm: install, upgrade, rollback, and uninstall workflows

- Custom Resource Definitions with OpenAPI schema validation

- CoreDNS forwarding failure diagnosis and fix

- CrashLoopBackOff debugging, node NotReady recovery, log extraction

- Control plane static pod repair via /etc/kubernetes/manifests

- Pod Disruption Budgets for maintenance safety

- Container runtime setup with cri-dockerd

- Resource requests, limits, and capacity calculations

- Multi-container pods and sidecar log streaming pattern

Reinforcement Sections:

- 6 NetworkPolicy exercises covering namespace scope, cross-namespace traffic, egress restrictions, and port filtering

- 7 StorageClass and PVC exercises including ReadOnlyMany, ReadWriteMany, and stateful database volumes

- Certificate management with self-signed TLS secrets and cert-manager

- Cluster troubleshooting: CrashLoopBackOff, DiskPressure, DNS failures, scheduling constraints, worker node failure

- Resource quotas, node affinity, taints and tolerations, ConfigMaps and Secrets

- HPA, PodDisruptionBudgets, and namespace-level resource limits

Each scenario includes a clear objective, lab versus exam requirement comparison, step-by-step commands, verification checks, and an exam tip that targets the most common mistakes.

WHO THIS IS FOR:

Engineers preparing for the CKA exam who want structured, command-driven practice. DevOps and platform engineers who are new to Kubernetes or want to fill gaps in their cluster operations skills. Kubernetes engineers who learn best by doing rather than reading. Instructors who need production-realistic labs with explanations they can adapt for their students.

A free edition is available with a smaller set of scenarios so you can evaluate the format and depth before purchasing the full version.
