CKA, CKAD, CKS - Jan 03 2022
CKA & CKAD Environment
Each task on this exam must be completed on a designated cluster/configuration context.
To minimize switching, the tasks are grouped so that all questions on a given cluster appear consecutively.
There are six clusters (CKA) / four clusters (CKAD) that comprise the exam environment, made up of varying numbers of containers, as follows:
CKA Clusters | |||
Cluster | Members | CNI | Description |
k8s | 1 master, 2 worker | flannel | k8s cluster |
hk8s | 1 master, 2 worker | calico | k8s cluster |
bk8s | 1 master, 1 worker | flannel | k8s cluster |
wk8s | 1 master, 2 worker | flannel | k8s cluster |
ek8s | 1 master, 2 worker | flannel | k8s cluster |
ik8s | 1 master, 1 base node | loopback | k8s cluster − missing worker node |
CKAD Clusters | |||
Cluster | Members | CNI | Description |
k8s | 1 master, 2 worker | flannel | k8s cluster |
dk8s | 1 master, 1 worker | flannel | k8s cluster |
nk8s | 1 master, 2 worker | calico | k8s cluster |
sk8s | 1 master, 1 worker | flannel | k8s cluster |
CKS Environment
Each task on this exam must be completed on a designated cluster/configuration context.
Sixteen clusters comprise the exam environment, one for each task. Each cluster is made up of one master node and one worker node.
Common Enviroment
For your convenience, all environments, in other words, the base system and the cluster nodes, have the following additional command-line tools pre-installed and pre-configured:

The CKA & CKAD environments are currently running Kubernetes v1.22. The CKA, CKS and CKAD exam environment will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date.
