Two weeks ago I passed the Linux Foundation Certified Kubernetes Administrator exam. With this exam, I have earned the Certified Kubernetes Administrator certification. It has been a great learning experience during the preparation for the exam.
In the following paragraphs, I will share my experience with the exam and an overview of the exam and the certification.
I am an IT professional with ten years of experience in the relevant field. I worked in an international software house as an IT administrator. I have hands-on experience with Linux and various development platforms. A few months back we entered into a long-term contract involving the Kubernetes platform. I was assigned a task by the company to get myself acquainted with the Kubernetes within two months. As my basic role is that of an administrator so I was assigned to get qualified through Certified Kubernetes Administrator CKA Dumps. One of my seniors from the head office briefed me about the exam and the preparations.
For the training material, I opted for the Myexamcollection as recommended by my colleague. I downloaded the free demo of the Certified Kubernetes Administrator exam from the Myexamcollection website to evaluate the quality of the training material. Upon my satisfaction, I selected the full package of PDF and the Testing Engine for the Certified Kubernetes Administrator exam from Myexamcollection. I came to know then that Myexamcollection offers a money-back guarantee for sure success in the first attempt and It added a lot to my confidence with the quality of the contents. I found the braindumps by Myexamcollection.com to be truly helpful because of the accuracy of the content. With the help of this authentic training material, I was able to finalize my preparation for the Certified Kubernetes Administrator exam in seven weeks. After a week-long revision, I took the exam and was able to pass it on my first attempt with a score of 85%.
Here is a brief introduction of the Linux Foundation, Certified Kubernetes Administrator Certification, and the exam.
Linux Foundation
The Linux Foundation is a non-profit consortium dedicated to fostering the growth of Linux. Founded in 2007, The Linux Foundation sponsors the work of Linux creator Linus Torvalds and is supported by leading Linux and open source companies and developers from around the world.
The Linux Foundation works closely with open source project communities to deliver relevant, respected, hands-on certifications to technology professionals around the world. The Linux Foundation is unique in that it doesn’t just provide the certifications for today’s most in-demand technologies; the involvement goes far beyond that. It hosts the projects developing these technologies and provides resources and staffing to help keep these development communities healthy and thriving. So when it comes right down to it, no one is closer to these technologies than The Linux Foundation.
Certified Kubernetes Administrator (CKA)
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 Administrator (CKA) program provides assurance that CKAs have the skills, knowledge, and competency to perform the responsibilities of Kubernetes administrators.
The Certified Kubernetes Administrator (CKA) program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation, to help develop the Kubernetes ecosystem.
This certification is for Kubernetes administrators, cloud administrators, and other IT professionals who manage Kubernetes instances.
CKA 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 an online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes.
A certified K8s administrator has demonstrated the ability to do the basic installation as well as configuring and managing production-grade Kubernetes clusters. They will have an understanding of key concepts such as Kubernetes networking, storage, security, maintenance, logging and monitoring, application lifecycle, troubleshooting, API object primitives, and the ability to establish basic use-cases for end users.
