Mastering Kubernetes: Certification Exam Breakdown and Study Resources
27 May, 2024

Have you heard about Kubernetes? It is this super cool tool that helps companies manage their fancy cloud applications. It’s highly sought after! Getting certified in Kubernetes is like getting a gold star that says, “I know my stuff!” It’s super important for individuals and companies because it shows they are experts in this cool tech.

So, in this article, we are going to talk all about Kubernetes certification exams. We’ll break down what they are all about and give you a bunch of awesome study resources to help you pass with flying colors and show off your skills. Let’s dive in and get you certified!

What is Kubernetes?

Kubernetes is an open-source platform designed to automate deploying, scaling, and managing containerized applications. But what does that mean? Imagine containers as tiny, self-contained packages that hold everything an app needs to run smoothly. Kubernetes acts like a conductor, orchestrating these containers across clusters of machines, whether they are on-premises or in the cloud.

With Kubernetes, you can tell it how many instances of your app you want, and it’ll make sure they are running, even if some machines go down. It handles scaling, load balancing, and resource management, so your apps stay stable and performant no matter what.

Think of it like a super-smart traffic controller for your apps, ensuring they are always in the right place at the right time, regardless of how many or how few there are. It’s like having a team of experts managing your apps 24/7, without the need for human intervention.

In short, Kubernetes simplifies the complexities of managing modern applications, making it easier for businesses to embrace cloud-native technologies and scale their operations efficiently.

A Closer Look at Kubernetes Certifications

Kubernetes certifications are like special badges given by the Cloud Native Computing Foundation (CNCF), which is part of the Linux Foundation. Getting certified means you have demonstrated proficiency in specific aspects of Kubernetes, such as administration, development, or security. These certifications can lead to exciting opportunities in the tech industry.

CNCF certifications come in four levels:

– The Associate level helps you learn basic skills before starting a job.

– The Developer level shows you are good at certain tasks.

– The Administrator level proves you can handle Kubernetes well. Exams are online and based on how you perform.

– The Specialist level focuses on specific skills, like security. Some Specialist certifications might need an Administrator certification first.

Here’s a breakdown of the main Kubernetes certifications:

– Kubernetes and Cloud Native Associate (KCNA)

– Kubernetes and Cloud Security Associate (KCSA)

– Certified Kubernetes Application Developer (CKAD)

– Certified Kubernetes Administrator (CKA)

– Certified Kubernetes Security Specialist (CKS)

Now, let’s take a closer look at each of them.

Kubernetes and Cloud Native Associate (KCNA)

The Kubernetes and Cloud Native Associate (KCNA) certification is a starting point for those who are interested in Kubernetes and cloud-native stuff. It’s perfect for beginners who want to show they understand the basics and are ready to learn more. It’s great for students or professionals looking to dive into cloud-native tech and possibly get more advanced certifications later on.

The KCNA exam is online and has multiple-choice questions. Passing this exam means you understand the basics of Kubernetes and cloud-native tech, including how to start apps with simple commands, the setup of Kubernetes (like containers and pods), and the main concepts of cloud-native security.

The exam costs $250, and you get one chance to retake it for free.

Kubernetes and Cloud Security Associate (KCSA)

The Kubernetes and Cloud Security Associate certification is like a starting point for those who want to focus on security in cloud-native tech. It’s made for individuals who want to move into more advanced roles and focuses on basic security skills.

This exam checks if you know how to check and improve security in Kubernetes clusters. It tests your ability to make controls stronger, watch over security, and find and understand risks and weaknesses. To put it simply, it’s a great certification for those who want to get better at cloud-native security.

The exam is online and has multiple-choice questions. It costs $250, and you get one opportunity to retake it at no additional cost.

Certified Kubernetes Application Developer (CKAD)

The Certified Kubernetes Application Developer certification helps specialists improve their skills in creating apps with Kubernetes. As more people use this platform, CNCF wants more developers to understand it well. Passing the CKAD exam means you can make and manage cloud-native applications on Kubernetes, focusing on practical skills tested with real tasks. You should already know about container runtimes and microservices, which are important for developers in the Kubernetes job market.

CKADs can set up app resources and use basic tools to make, watch, and fix scalable apps in Kubernetes. The exam checks if you can work with container images, use cloud-native app ideas, and manage Kubernetes resources. The exam costs $395, and you get one chance to try again for free.

For training, the Kubernetes for Developers (LFD259) course covers making, hosting, and setting up apps in a multi-node cluster. It’s good for developers who know Linux, Python, Node.js, or Go. It gets you ready for the CKAD exam by teaching skills you’ll use in real jobs.

Certified Kubernetes Administrator (CKA)

The Certified Kubernetes Administrator certification is a popular credential for professionals showcasing their practical Kubernetes skills. It’s a hands-on exam where candidates solve real-world problems using command lines, not just answering multiple-choice questions. This certification proves your ability to administer Kubernetes clusters.

The CKA exam goes on for two hours and checks lots of different abilities like setting up clusters, managing workloads, handling networking, storage, and fixing issues. It costs $395 to take the exam, and you get one free try if you need it.

To prepare for the CKA exam, you can take the Kubernetes Fundamentals (LFS258) course. This course covers Kubernetes basics, teaching you how to deploy containerized applications, manage resources via the API, and configure a production-grade Kubernetes cluster. It’s suitable for existing IT administrators or those looking to start a cloud career. Completion of this course, along with real-world experience and study, prepares you for the CKA exam.

Certified Kubernetes Security Specialist (CKS)

The Certified Kubernetes Security Specialist certification is for those who focus on keeping Kubernetes secure. With Kubernetes growing fast, CNCF wants to train security experts to make organizations safer.

The CKS exam is hands-on and needs a current CKA certification. It covers the best ways to keep apps and Kubernetes platforms secure. The CKS certification lasts for two years and helps security experts prove their skills quickly.

The exam checks different skills like setting up secure clusters, fixing weaknesses, and keeping apps safe while they run. It’s like a real-world test where you prove you know how to keep Kubernetes and cloud systems secure. It costs $395 to take the exam, and you can try again for free if needed.

For training, the Kubernetes Security Essentials (LFS260) course is perfect for those who already have the CKA certification. It teaches you the best ways to keep container-based apps and Kubernetes platforms safe. By focusing on security issues in cloud environments where apps are used, it helps you get ready for the CKS exam.
