About the CKAD
The Certified Kubernetes Application Developer (CKAD) exam certifies that candidates can design, build and deploy cloud-native applications for Kubernetes. The CKAD was created by the Linux Foundation and the Cloud Native Computing Foundation (CNCF) as a part of their ongoing effort to help develop the Kubernetes ecosystem. The exam is online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes.


Exam Details & Resources
This exam is an online, proctored, performance-based test that consists of a set of performance-based tasks (problems) to be solved in a command line. Candidates have 2 hours to complete the tasks.

Candidates who register for the Certified Kubernetes Application Developer (CKAD) exam will have 2 attempts (per exam registration) to an exam simulator, provided by Killer.sh.  

The exam is based on Kubernetes v1.30.
The CKAD exam environment will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date

There are no pre-requisites for this exam.

This exam really teaches you how to tackle real-world challenges. What stood out to me was the absence of those tedious questions where you're just copying and pasting YAML from the documentation website – you know, like creating a PV, PVC, StorageClass, NetworkPolicy. I didn't even have to open the browser during exam! Two hours is plenty of time to work through all the questions. And let's not forget the huge perk of getting two free sessions on killer.sh. That platform is fantastic, and the fact that its questions are even tougher than the actual exam is a bonus – it really boosts your confidence.

What I most like about the Linux Foundation exams are the hands-on questions. Few certifications offer the enjoyable experience of being evaluated using current work-related assignments.

CKAD allows anyone who wishes to enter into k8s development and test their expertise to become confident with their skills. I believe having a performance-based exam is the best way to assess your skills, and the CKAD exam offers such a way to assess your k8s skills.

I admired the fact that the exam is a hands-on practical set of real-world problems Going through the exam provides the feeling of applying all of the knowledge to create something or troubleshoot existing issues The process itself is very smooth as it is possible to copy key elements from the question to avoid typos for example, and all is needed is to focus on the task at hand.

I want to extend my sincere appreciation to the Linux Foundation for the CKAD (Certified Kubernetes Application Developer) practical exam. It stands out as the best exam I've taken so far. The questions were meticulously crafted, ensuring a comprehensive test of one's knowledge, and the PSI environment provided an impeccable and smooth testing experience without any hitches. Kudos for setting such high standards!

The most notable aspect of the exam was its performance-based format, which surpasses traditional multiple-choice questions as a superior method for assessing knowledge. This format enables individuals to showcase their skills and practical understanding in real-world scenarios, allowing for a comprehensive and accurate evaluation of their capabilities.

The CKAD exam tests you on a broad level of topics K8s administrators need every day. I feel very ready to work on production workloads after passing the exam.
