I just passed this certification few month ago and wrote down some notice for the people who want to take this certification.

1/ Why we take ckad:
The Certified Kubernetes Application Developer exam certifies that users can design, build, configure, and expose cloud native applications for Kubernetes. A Certified Kubernetes Application Developer can define application resources and use core primitives to build, monitor, and troubleshoot scalable applications and tools in Kubernetes. This cert will suitable for the developer, software engineer who is working on the containerlize. If you were a system engineer who operate, maintainer the k8s, i recommend to read this course CKA (https://medium.com/@luongvinhthao/how-to-get-the-cka-from-beginner-6923c5f2c546)

2/ Prerequisites:

There are no prerequisites to get this certificate but i recommend to have a linux skill and docker basic knowdlege .
The exam will be on ubuntu or centos so that we need to know about this OS and vim skill to edit the yaml config.
For docker , you can refer a simple course here. https://kodekloud.com/p/docker-for-the-absolute-beginner-hands-on

3/ Exam information CKAD:

5/ Tip and trick:

CKAD cert is mainly focus on the pod and how to design multi container. So that, you need to understand clearly on this pod desgin.

You will have 120 minutes so that please manage your time carefully and don’t panic when you read the question. My experience is by pass some hard question and come back to this when you finish the other.

Remember the kubectl cheat sheet and some alais neccessary : https://kubernetes.io/docs/reference/kubectl/cheatsheet/

Again : PRACTICE , PRACTICE and PRACTICE will help you confident for the exam.
