A brainchild of Google, Kubernetes was later donated to Cloud Native Computing Foundation (CNCF) soon after its inception. Since then CNCF is handling its implementation and deployment.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Alongside, CNCF also offers two Kubernetes certifications to gain deeper, insightful, and advanced knowledge of Kubernetes. These kubernetes certifications are among the <a href=\"https:\/\/www.easydeploy.io\/blog\/best-devops-certifications\/\" target=\"_blank\" rel=\"noopener noreferrer\">top DevOps certifications<\/a>. Let&#8217;s dive deep to get more details.<\/span><\/p>\n<h2 style=\"text-align: justify;\">What are the Kubernetes Certifications?<\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Unlike other IT certification, Kubernetes certifications are relatively new and it&#8217;s still in their infancy stage.

Read our previous post to know\u00a0what are <a style=\"font-size: 1.125rem;\" href=\"https:\/\/www.easydeploy.io\/blog\/kubernetes-pods\/\" target=\"_blank\" rel=\"noopener noreferrer\">Kubernetes pods.<\/a><\/p>\n<\/blockquote>\n<h3 style=\"text-align: justify;\"><b>Preparation Guide for Kubernetes Certifications\u00a0<\/b><\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Though you are eligible to take a free exam retake for the kubernetes certifications if you don\u2019t clear it in the first attempt, getting certified in one go has its own charm. Though it looks like, it is not an easy task. Here are our suggestions to achieve this &#8211;<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>Make the most of exam resource<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">CNFC makes your certification journey as easy one since the beginning by offering rich and resourceful study material. There are candidate handbook and curriculum overview to know what all is there in the exam and which study material should refer to it. If you really want to make big in your first attempt then you should gauge little extra in these exam resources.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Practice and practice a lot<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">As both of these certifications are performance-based; the only way to come up with flying colors is to practice and practice a lot. You should practice the Kubernetes concepts in a real-time environment. You can take the help of various online labs for this.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Make sure that you are practicing for a minimum of 3-4 times. Above all, the kubectl command line is something which requires most of the attention. This command line is what you would be using throughout the exam for quick problem resolving.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Master the art of command line<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">As you would be giving exam only in the command line, you should be well aware of its concepts beforehand. Make sure you are practicing with text editors such as vim.\u00a0 Learn to do quick copy &amp; paste between your editor and Linux Foundation\u2019s editor. The more accurately and quickly you are doing this, the easier would be the time management on the D-day.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Make learning thorough with tutorials<span style=\"font-weight: 400;\">\u00a0<\/span><\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">There are ample of tutorials available online that will help you to get a clear picture of Kubernetes concepts. Go through a few tutorials and training videos to prepare yourself for the exam.<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Join the communities<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">You can also join the Kubernetes communities to gain more practical and detailed knowledge of the Kubernetes\u2019 concepts. In these communities, Kubernetes\u2019 professionals from across the globe are there to share their real-time experiences with conjectural Kubernetes concepts. This will strengthen your learning.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Join free training<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">There are many online platforms that provide free online basic Kubernetes programs. If Kubernetes is the pretty alien thing to you then these courses will help you learn its basic yet key concepts without even spending a single penny. Udacity, Udemy, and edX are our top pick for this.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>Check your system compatibility<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">To appear in the exam, your system should have certain hardware and software compatibility. We would suggest you run a compatibility check tool on your system a few days prior. Any last minute hassle can panic you.<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Make most of the notepad feature<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">While you are attempting questions, don\u2019t forget to use Notepad feature in your exam console at its fullest. As you are not allowed to take notes anywhere else, this exam console will help you to answer the questions in the right manner. In Notepad, you can edit\/delete\/modify your answer again and again till your final satisfaction and then submit into the exam terminal.\u00a0<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<h4>\u00a0 Learn to ditch Ctrl C and Ctrl V<\/h4>\n<\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">These two commands may have become a part of your regular operations but it\u2019s the time to ditch them as they won\u2019t work you your exam terminal. Refer candidate handbook to know about their replacements and try to practice them before the exam.\u00a0<\/span><\/p>\n<blockquote><p>Also Read: <a href=\"https:\/\/www.easydeploy.io\/blog\/why-kubernetes-called-k8s\/\" target=\"_blank\" rel=\"noopener noreferrer\">Why is Kubernetes called k8s?<\/a><\/p><\/blockquote>\n<h3 style=\"text-align: justify;\">Tips for D-Day<\/h3>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">So, you all are prepared for exam and D-day has arrived. Here is what you should do on the exam day &#8211;<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Make sure you choose a room with a minimum or no-disturbance environment. Keep your phone and any other electronic device out of your reach as they may distract.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Always use Google Chrome as your default browser while appearing in the exam.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">As you are allowed to use Kubernetes official documentation for the references during the exam, keep it handy.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Ensure that your webcam is working well and positioned right.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Keep your laptop\/PC fully charged and have a handy power backup as well.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Do not stop or tamper with the cer terminal process. Doing so may lead to session expiration.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">You should not block any of 8080\/tcp, 4505\/tcp, and 4506\/tcp incoming blocks.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Make sure that you are taking up the exam in the right cluster. For the CKA exam, there are six clusters and for the CKAD exam, there are four clusters.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Don\u2019t spend a lot of time on a single question. If you stuck then note it in the notepad and proceed further.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Try to answer the easy questions first. By doing this, you will be able to reach the minimum passing requirement. Once you are done with all the easy questions, proceed towards the questions of medium difficulty. Your chief aim should be touching the mark of minimum passing marks first.\u00a0<\/span><\/li>\n<\/ul>\n<h4 style=\"text-align: justify;\">What about the result?<\/h4>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">You can expect the result of your exam within 36 hours after you completed the exam.\u00a0 Candidates can check their result on \u201cMy Portal\u201d. You will also get your result in email as well. The minimum passing score for the CKA exam is 74% and for CKAD is 66%. Both the exams are available in Kubernetes v1.14 version.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">If you haven\u2019t cleared the exam in the first attempt then you can take another retake within 12 months for the first attempt. If you haven\u2019t cleared the exam in free retake as well then you had to pay the course fee again.\u00a0<\/span><\/p>\n<h4 style=\"text-align: justify;\">How much these certifications will cost you?<\/h4>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">In general, the cost of each certification is $300 USD.\u00a0 In this fee, you will be able to use the document case studies and study material mentioned at the CNFC website. Also, you are eligible to avail one free re-take in this amount. There is a bundle offer available as well. In this bundle offer, you can take up Kubernetes Fundamentals training (LFS258) together with the exam for $499 USD in whole.\u00a0<\/span><\/p>\n<h4 style=\"text-align: justify;\">For how long these certifications will be valid?<\/h4>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Once earned successfully, your CKA certification will be valid for 3 years and CKAD is valid from two years from the date of issue. You can go for recertification and renewal as well after the validity expires.\u00a0<\/span><\/p>\n<h4 style=\"text-align: justify;\">Final words<\/h4>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Kubernetes is not going to fade away any time soon.
