Exam Technical Instructions

  1. Root privileges can be obtained by running 'sudo −i'.

  2. Rebooting of your server IS permitted at any time.

  3. Do not stop or tamper with the certerminal process as this will END YOUR EXAM SESSION.

  5. Use Ctrl+Alt+W instead of Ctrl+W.

    5.1 Ctrl+W is a keyboard shortcut that will close the current tab in Google Chrome.

  6. Ctrl+C & and Ctrl+V are not supported in your exam terminal. To copy and paste text, please use;

    6.1 For Linux: select text for copy and middle button for paste (or both left and right simultaneously if you have no middle button).

    6.2 For Mac: ⌘+C to copy and ⌘+V to paste.

  8. Only a single terminal console is available during the exam. Terminal multiplexers such as GNU Screen and tmux can be used to create virtual consoles.

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

CNI

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.

  • 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 Kubernetes v1.19. (Quarterly exam updates are planned to match Kubernetes releases).
