These are excerpted from the upgraded package of my book for web application developers getting their Kubernetes certification. While not actual questions from the exam, these questions are of a similar style and content to questions from the real exam.

The upgraded package of my book contains a realistic three hour, thirty question practice exam with complete solutions. This premium exam contains more realistic, more challenging questions and solutions that will test your ability to work in an existing Kubernetes cluster under time constraints.

Create a namespace called ggckad-s0 in your cluster. Run the following pods in this namespace. All operations in this question should be performed in the ggckad-s2 namespace.

Create a pod that has two containers. The first container should run as user IDand the second container with user ID Both containers should use file system group ID All operations in this question should be performed in the ggckad-s4 namespace. This image is in the main Docker repository at hub. The web server listens on port It returns a status code response when the application is healthy.

The application typically takes sixty seconds to start. Create a pod called questionpod to run this application, making sure to define liveness and readiness probes that use this health endpoint. All operations in this question should be performed in the ggckad-s5 namespace. Create a file called question Configure the deployment so that when the deployment is updated, the existing pods are killed off before new pods are created to replace them.

They are doing a great job in developing such a realistic and hands-on certification compared to the exams of the MCQ format. However, this is truly, visionary for all of us.

Seriously, you can take a look at these course. Living and breathing with YAML syntax is the most important thing. For Kubernetes, it is the de-facto language and learning the complexities can allow you to go a long way for overall planning. There are a lot of online tools available and my first pick is one from tutorialspoint. Read on. Understand critical shortcuts such as line deletion, copy yanking pasting, and navigation.

Please note: I suggest vim, as it will surely be helpful for you in the future and not just for passing the CKAD exams and test. Are you fully new to Kubernetes or would you like to upgrade the basics again? Before heading straight into CKAD details, this is a terrific primer. Click Here for Introduction to Kubernetes for beginners. He describes the principles very clearly and comes with assessments for practise as well. Here, a word of warning regarding practise tests-the ones given are basic and so you might want to focus on some external sample questions.

It will also allow you to extract the data into a YAML definition for you to change later. This best of the best. It will help you avoid typing extra characters. Furthermore, kubectl provides several handy shortcuts such as po podsrs replicasetsdeploy deploymentsnetpol network policies etc.

A sample usage will now look like k get po to show all the pods instead of getting pods from kubectl. In this examination, you are authorised to refer to the official documentation of Kubernetes. Get acquainted with this and know what needs to be researched and where to look when in doubt. For this exam, the search box on the top right of this page is your guiding light. As can be seen above, recursive should be your default man page. Although you would be allowed to open an additional tab to bring up the official documentation.

So, I honestly felt that it was better to search within the terminal right there because it is an integrated syntax documentation to check on the go. Learn to use this for your success and to abuse it.I begin with stating that the title is a click bait and my playing around with words. I do not want to explain why I gave this exam, I just did because I wanted to learn kubernetes — not because what others would say about it.

I think everyone in their job, when either get Passionate about something or Desperate about something, achieve something extraordinary. Same was my journey towards CKAD. I wanted to get fire in my belly to have some goal for learning at much faster pace. And active learn from a passive watcher. The whole act was in my case passionate if not really desperate to get the certification. To an extend writing this blog, now I feel somewhat sad that the developer journey has ended, though there are lot to do.

It gave a very basic introduction of the core concepts for kubernetes. For me it helped to kick start the whole journey. This course is a must for passing the exam. This should be the next logical step towards preparing yourself for the certification. Actually you will join their slack channel and see every day one of the other person posting about clearing the CKAD exam or even CKA — you would start feeling sometimes confident about clearing, sometime irked that it is taking you too long to get to that stage.

Stay your course no matter what happens and do read about others experience. Trust me nothing can prepare you, more than you yourself. I have added the one github repo [4] in the reference section below, which is the most popular one. There are several others people like to go through, but for me it was sufficient whenever I do not want to see recording but just want to practice whether I still remember the commands. There are numerous other ways to actually go practice — one definite way is work on an actual project which involves Kubernetes — not sure possible for everyone.

I too end up volunteering for a team which really helps. I still keep this [4] here because it helped in preparing my mind to sit through 2hour of mindful questions.The introduction of containers provided an exceptional boost to the field of application development.

While the majority of the discussion regarding containerization technology used to focus on Docker only in the initial days, Kubernetes has also garnered substantial popularity in recent times.

Subsequently, readers could also find the important steps for effective certified Kubernetes application developer exam preparation. The primary objective of the certification program is the expansion of the Kubernetes ecosystem by leveraging standardized certification and training.

The CNCF recognizes the value of certification in supporting the growth of a community of application developers specializing in Kubernetes. The CKAD certification can help application developers prove their value and credibility in the job market.

In addition, the certification is also helpful for enterprises to hire competent professionals to foster their growth. The CKAD exam tests the abilities of users in designing, developing, configuring, and exposing cloud-native applications for Kubernetes. The ideal target audience for this exam involves a candidate aspiring to prove skills in the definition of application resources.

The candidates should also have an interest in showcasing skills for using core primitives in building, monitoring, and troubleshooting scalable applications and tools on Kubernetes. Basically, the CKAD exam primarily aims at verifying that certified candidates have the required knowledge, experience, and skills for performing the responsibilities of Kubernetes application developers. The prerequisites for the exam establish the capabilities of the candidate to take on the exam.

You can think of the recommended requirements for the exam as vital support for your readiness for the CKAD exam. The candidates for the CKAD exam should have fluency in the following.

The exam also implies the requirements for having knowledge regarding microservices architecture and container runtimes.
