System Requirements to take the exam

Candidates should run the PSI Online System Security Check to verify that their machine meets the technical requirements for taking a proctored exam.
The online proctored exam is taken on PSI's proctoring platform "Bridge", using the PSI Secure Browser (a web browser created to guarantee a secure exam delivery over a virtual connection).

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

  • At the start of each task you'll be provided with the command to ensure you are on the correct cluster to complete the task.
  • Nodes making up each cluster can be reached via ssh, using a command such as the following: ssh <nodename>
  • You can assume elevated privileges on any node by issuing the following command: sudo -i
  • You can also use sudo to execute commands with elevated privileges at any time
  • You must return to the base node (hostname node-1) after completing each task.
  • Nested−ssh is not supported.
  • You can use kubectl and the appropriate context to work on any cluster from the base node. When connected to a cluster member via ssh, you will only be able to work on that particular cluster via kubectl.
  • 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:
    • kubectl with kalias and Bash autocompletion
    • jq for YAML/JSON processing
    • tmux for terminal multiplexing
    • curl and wget for testing web services
    • man and man pages for further documentation
  • Further instructions for connecting to cluster nodes will be provided in the appropriate tasks
  • Where no explicit namespace is specified, the default namespace should be acted upon.
  • If you need to destroy/recreate a resource to perform a certain task, it is your responsibility to back up the resource definition appropriately prior to destroying the resource.
  • The CKA & CKAD environments are currently running etcd v3.5.
  • The CKA environment is currently running Kubernetes v1.23.
  • The CKAD environment is currently running Kubernetes v1.23. 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.
