Introduction

Kubernetes Certifications

The Cloud Native Computing Foundation offers three major certifications to validate your skills and expertise in managing Kubernetes clusters. These certifications are recognized worldwide and help validate your knowledge with recruiters and companies.

CKA (Certified Kubernetes Administrator)

The CKA is intended for system administrators who want to demonstrate their mastery of Kubernetes cluster administration. It covers essential aspects of managing and operating a Kubernetes cluster.

CKAD (Certified Kubernetes Application Developer)

The CKAD is suited for developers who want to prove their ability to design, build, and deploy cloud-native applications on Kubernetes. This certification focuses on development skills and using Kubernetes to run applications.

CKS (Certified Kubernetes Security Specialist)

The CKS is an advanced security-oriented certification. It is ideal for Kubernetes professionals who want to deepen their expertise in securing Kubernetes clusters and applications, including network configuration, security policies, and vulnerability management.

Certification Process

Kubernetes certifications are practical online exams that require using a terminal to solve real-world scenarios. You will have access to a Kubernetes cluster and must complete several tasks within a limited time.

Exam Structure

  • Duration: Approximately 2 hours.
  • Mode: 100% online.
  • Questions: 15 to 20 scenarios to solve on a real Kubernetes cluster.
  • Format: Exam in a terminal embedded in a browser, with access to official Kubernetes documentation (https://kubernetes.io/).

Preparation

It is recommended to have good knowledge of command-line tools (CLI) and Kubernetes before attempting the certifications. The exam is very practice-oriented, so it is essential to practice with Kubernetes clusters.

The Environment

The exam environment is a secure space where you will have access to a terminal to interact with a Kubernetes cluster. Here are some elements to know before taking the exam:

  • Access to official documentation: You have the right to consult official Kubernetes documentation during the exam. It is crucial to know how to quickly navigate the documentation.
  • Restrictions: You cannot use local tools on your machine, nor copy/paste external scripts. Everything must be done in the provided environment.
  • Real-time supervision: A person will monitor you via webcam throughout the exam to ensure its integrity.
