Certified Kubernetes Administrator (CKA) Certification Guide
The Certified Kubernetes Administrator (CKA) from the Cloud Native Computing Foundation (CNCF) is the premier credential for proving you can run and manage Kubernetes clusters. Unlike most exams, CKA is fully hands-on in a live terminal.
Who Should Take CKA
- DevOps engineers and platform engineers
- Site reliability engineers (SREs) managing containers
- Cloud and infrastructure engineers adopting Kubernetes
Exam Overview
| Aspect | Details |
|---|---|
| Format | Performance-based, hands-on in a live cluster |
| Duration | 2 hours |
| Passing Score | 66% |
| Delivery | Online proctored, with one free retake |
| Cost | Around 445 USD (often bundled with a Killer.sh simulator) |
| Validity | 2 years |

| Domain | Weight |
|---|---|
| Cluster Architecture, Installation and Configuration | 25% |
| Workloads and Scheduling | 15% |
| Services and Networking | 20% |
| Storage | 10% |
| Troubleshooting | 30% |
Key Skills to Master
- Managing pods, deployments, daemonsets, and jobs
- Services, ingress, network policies, and DNS
- Persistent volumes, persistent volume claims, and storage classes
- RBAC, cluster upgrades with kubeadm, and etcd backup and restore
- Reading logs and events to troubleshoot failing workloads
Kubernetes is YAML-driven and uses base64 for Secrets. Brush up with a Base64 Encoder so decoding and encoding secret values feels natural in the exam terminal.
Exam-Day Tips
- Master kubectl speed: Use imperative commands and generators to create resources fast
- Use the docs: The official Kubernetes documentation is allowed during the exam
- Set up aliases and context switching early to save time
- Flag and skip hard tasks, then return once easy points are banked
