The Certified Kubernetes Administrator (CKA) certification is designed to ensure that certification holders have the skills, knowledge, and competency to perform the responsibilities of Kubernetes Administrators. The CKA certification allows certified administrators to quickly establish their credibility and value in the job market, and also allowing companies to more quickly hire high-quality teams to support their growth.
The Certified Kubernetes Application Developer (CKAD) certification is designed to provide assurance that certification holders have the skills, knowledge, and competency to perform the responsibilities of Kubernetes application developers. A Certified Kubernetes Application Developer can define application resources and use core primitives to build, monitor, and troubleshoot scalable applications and tools in Kubernetes.
The A Certified Kubernetes Security Specialist (CKS) certification is designed to provide assurance that certification holders are accomplished Kubernetes practitioners (as evidenced by holding the CKA credential) who have demonstrated competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime.
Certified Kubernetes Security Specialist (CKS) candidates must have taken and passed the Certified Kubernetes Administrator (CKA) exam prior to attempting the CKS exam.
CKS may be purchased but not scheduled until CKA certification has been achieved. CKA Certification must be active (non-expired) on the date the CKS exam (including Retakes) is scheduled.
The exam costs $300 USD.
The certification exam is proctored remotely via streaming audio, video, and screen sharing feeds. The screensharing feed allows proctors to view candidates' desktops (including all monitors). The audio, video, and screen sharing feeds will be stored for a limited period of time in the event that there is a subsequent need for review.
Exams are delivered online and Candidates must provide their own computer with:
Current version of Chrome or Chromium
you don’t need to install a virtual machine, use a client machine, or anything beyond a Chrome or Chromium browser

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)
Please check to make sure it is working before you start your exam session.
Ensure the webcam is capable of being moved as the proctor may ask you to pan your surroundings to check for potential violations of exam policy.
Try holding up your ID while viewing your webcam feed to ensure your placement and resolution are sufficient for the person viewing your feed to read your ID.

The Linux Foundation offers a free Introduction to Kubernetes course which provides an introduction to many key concepts for Kubernetes. The Fundamentals of Kubernetes (LFS258) course builds on this introductory material and is designed as preparation for the Certified Kubernetes Administrator Exam.
The topics covered in the Kubernetes for Developers (LFS259) course are directly aligned with the knowledge domains tested by the Certified Kubernetes Application Developer Exam.
We understand that taking the exams via remote desktop and a new platform environment may cause a lag time for some, however there are trade offs needed to offer this exam remotely. We will continually monitor and seek to improve the testing experience over time.
When eligible, we do offer free retakes for those who do not pass the first time, regardless of why.
