Fascinating Certified Kubernetes Security Specialist (cks) Exam Tactics That Can Help Your Business Grow
PRACTICE There are many ways to set up a single controller single worker Kubernetes cluster. I used Vagrant-VirtualBox to set up a single controller, two worker Kubernetes set up using kubeadm. You can find the Vagrantfile and instructions to use it here. Once you have gone through all the study material and are unsure if you are ready for the exam, then the simulator will help you gauge your progress. Once you buy the killer.sh course, you get access to the simulator. Another way to get access to the simulator is by buying the exam. Now you get access to the same simulator even by just purchasing the exam. I think CNCF and killer.sh has some kind of tie-up there. Official Kubernetes documentation does provide ample resources to practice NetworkPolicies. But I found this Github repository by Ahmet particularly helpful since it has various scenarios you can play with to better understand NetworkPolicies. Use kubectl describe with network policies to better understand them. Basic YAML configs could be confusing. In the exam, you have only one browser window open, which has a terminal and questions. It is helpful in the CKS exam to have multiple terminal windows to reduce cognitive load. To achieve this, you can use a tool like tmux. So while practicing for the exam, also practice tmux in your day-to-day work. To get started here is a tmux cheatsheet.
GENERAL TIPS If you struggle with keeping up with the exam studies, then schedule the exam and work backward. This way, you won’t have moving goalposts, and you will be forced to focus on your preparation. At any point, you are reading specific Kubernetes documentation, and you feel that the documentation can be helpful during the exam; just bookmark it. This is faster than searching the documentation during the exam. Here is a Github gist with links to all the docs that I bookmarked for the exam. By heart, all the quick helper commands using kubectl. It has many generator Certified Kubernetes Security Specialist (CKS) Examcommands that help you generate basic config, which can be used instead of fiddling with the YAML config from scratch. Most of such commands are documented in this cheat sheet document. As mentioned before, you can use kubectl to generate RBAC config as well. Practice creating RBAC config using kubectl. You should be able to generate Role, Rolebinding, ClusterRole, ClusterRolebinding using kubectl only. Follow this doc to learn these commands. Two weeks before the exam, become comfortable sitting for at least two hours uninterrupted at the exact same time as the exam. This helps prime your body to be comfortable on the day of the exam.

If you don’t know where the configs for a particular systemd service reside, use systemctl cat <process name> to find that. e.g., systemctl cat kubelet. BEFORE EXAM TIPS Disable Ctrl + W if you are used to that command on the terminal. On the terminal, this key combination is used to delete a word. But on a browser window, the same key combo could kill the exam window. Thus causing disturbances in your exam. If you are on Gnome-based Linux, here is a simple way to disable the key combination. This post explains setting up the command to a noop. On a typical desktop, windows manager takes precedence on the key combination. So once you set this key combination at that level, it stops working everywhere else. Clean the entire history of your browser. That way, any bookmark that you create does not conflict with your history.
