Important Instructions: CKA and CKAD
Any suspicious activity will be addressed and will result in consequences including, but not limited to, revoking a passing score and restricting an individual’s ability to take an exam again.
- The exams are delivered online and consist of performance-based tasks (problems) to be solved on the command line running Linux.
- The exams consist of 15-20 performance-based tasks.
- Candidates have 2 hours to complete the CKA and CKAD exam.
- The exams are proctored remotely via streaming audio, video, and screen sharing feeds.
- Results will be emailed 24 hours from the time that the exam is completed.
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).
PSI Secure Browser Download is made available to candidates at Exam Launch Time.
Candidates should review the Bridge FAQ Information, published by PSI, to prepare for the Secure Browser installation and be aware of how to resolve issues with the Installation/download or launch of their exam:
Candidates must provide their own computer with:
- All browsers are supported, however PSI highly recommends using the latest version of Google Chrome for the best exam scheduling experience, and because the secure browser is Chrome-based and will give a more accurate experience.
- One active monitor (either built in or external) (NOTE: Dual Monitors are NOT supported) The Linux Foundation recommends a screen size of 15” or higher to support the ExamUI. The Linux Foundation recommends a screen resolution of 1080p.
- Reliable internet access
- Ensure others on the same internet connection are not performing activities that use excessive bandwidth (i.e. holding conference calls, streaming content, gaming, etc.)
- A wired connection is often more stable and robust than a wireless connection
- Turn off bandwidth-intensive services (e.g. file sync, dropbox, BitTorrent)
- HTTPS connectivity to AWS S3 endpoints like https://*.s3.amazonaws.com/* is required, make sure your network environment is not blocking those requests (e.g. Firewall rules, HTTP Proxy, etc)
- Please check to make sure it is working before you start your exam session.
Candidates are not allowed to have other applications or browser windows running except the one on which the Exam is being shown.Please review the PSI Bridge Platform: System Requirements to ensure your machine will meet the requirements of our online proctor.
- Ensure the webcam is capable of being moved as you will have to pan your surroundings to check for potential violations of exam policy.
- If you will be testing from an employer-provide ISP or will use an employer provided machine, please ensure that streaming will be allowed using WebRTC.
- Please disable firewalls or use a computer without a corporate firewall. Firewalls may interfere with installing the secure browser needed to take the test.
- You should use a computer on which you have the privileges needed to install applications AND end system process' and services.
- You cannot take an exam using a virtual machine even though the compatibility check may not display any issues

- 1.Root privileges can be obtained by running 'sudo −i'.
- 2.You must NOT reboot the base node (hostname node-1). Rebooting the base node will NOT restart your exam environment.
- 3.Do not stop or tamper with the certerminal process as this will END YOUR EXAM SESSION.
- 4.Do not block incoming ports 8080/tcp, 4505/tcp and 4506/tcp. This includes firewall rules that are found within the distribution's default firewall configuration files as well as interactive firewall commands.
- 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.The Terminal (Terminal Emulator Application) is a Linux Terminal; to copy & paste within the Linux Terminal you need to use LINUX shortcuts:Copy = Ctrl+SHIFT+C (inside the terminal) Paste = Ctrl+SHIFT+V (inside the terminal) OR Use the Right Click Context Menu and select Copy or Paste

- Each task on this exam must be completed on a designated cluster/configuration context.
- An infobox at the start of each task provides you with the cluster name/context information.
- Nodes making up each cluster can be reached via ssh, using a command such as the following: ssh <nodename>
- NOTE: You must return to the base node (hostname node-1) after completing each task.
- Nested-ssh is not supported.
- 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 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:
kalias and Bash autocompletion
jqfor YAML/JSON processing
tmuxfor terminal multiplexing
wgetfor testing web services
manand 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 v1.27.
- The CKAD environment is currently running Kubernetes v1.27. 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.
