What is CKA?

The Certified Kubernetes Administrator (CKA) program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation, to help develop the Kubernetes ecosystem.

I passed the CKA on November 21, 2020 and I will talk about the experience and tips.

The exam

I grabbed the key information for the CNCF as below:

But also some other tips from my personal exam:

• You need to install the chrome plugin for the exam, may need use VPN in China;
• You can use Google account to access linuxfoundation.org;
• Don't waste time during the exam, it's just 2 hours;
• Set the command completion for kubectl before to answer the questions;
• Only two Chrome tabs are allowed;
• Use kubectl get/describe to check your answers before submit;
• Try to use kubectl create/scale/expose other than create the yaml files or edit;
• Use kubectl run with — dry-run flag as much as you can. It’s an easier and faster way to create resources in the cluster.
• Marked the question you are not sure, don't hung at it;
• Remember to switch the k8s context when you switch the question;
• If you ssh to remote servers, remember to be back after finishing the steps;
• Get familiar with the vi/vim before you take the exam;
• Bookmark the links you want to refer to;
• Review the cheatsheet, you will learn more;
• Review the docs, you will learn all;
• Take it easy! You will pass!
