WEBVTT 00:00.266 --> 00:03.191 -Hello, everyone, this is Vijin Palazhi from KodeKloud, 00:03.414 --> 00:07.573 and welcome to the ultimate CKA mock exam series. 00:09.949 --> 00:11.050 Now, before we begin, 00:11.130 --> 00:14.456 I wanted to talk to you about some of the prerequisites to consider 00:14.536 --> 00:16.592 before attempting this course. 00:16.782 --> 00:18.590 Now, since you're watching this video, 00:18.679 --> 00:22.244 I'm assuming that your CKA exam is right around the corner 00:22.328 --> 00:25.393 and that you have already completed the CKA preparation course 00:25.474 --> 00:28.707 with the included mock exams and the lightning labs. 00:28.911 --> 00:30.645 If this assumption is incorrect, 00:30.726 --> 00:34.495 I would highly recommend that you complete the CKA preparation course first, 00:34.576 --> 00:37.404 and then come back to this series of labs. 00:37.875 --> 00:40.927 Now, this course consists of a series of comprehensive 00:41.007 --> 00:42.783 and challenging mock exams 00:42.883 --> 00:45.376 intended to give you more hands-on practice 00:45.456 --> 00:47.879 before you attempt the actual exam. 00:48.349 --> 00:49.762 Each test is quite unique 00:49.842 --> 00:52.362 as compared to the regular mock exams and lightning labs 00:52.442 --> 00:54.623 that you will find in the CKA course. 00:55.536 --> 00:56.683 As you may already know, 00:56.763 --> 01:01.912 the CKA exam tests your practical knowledge in five key knowledge areas. 01:02.058 --> 01:05.260 The architecture, installation, and maintenance section 01:05.340 --> 01:08.169 consists of 25% of the questions. 01:08.397 --> 01:10.936 Workload scheduling is another 15%. 01:11.105 --> 01:13.499 Service networking is 20%. 01:13.717 --> 01:15.824 Storage is another 10% 01:15.959 --> 01:19.052 and finally, the biggest section of them all is troubleshooting, 01:19.129 --> 01:21.252 which accounts for 30% of the questions. 01:22.094 --> 01:24.254 Now, each of the tests in this series 01:24.412 --> 01:27.731 respects the weightage of these individual knowledge areas 01:27.812 --> 01:31.305 to give you the experience of taking an actual exam. 01:32.161 --> 01:33.651 To take it up another notch, 01:33.747 --> 01:36.217 the questions that you get for this mock exam, 01:36.322 --> 01:40.221 including the knowledge area themselves are completely randomized, 01:40.357 --> 01:43.157 which are curated from a large pool of questions 01:43.237 --> 01:46.269 and design by the KodeKloud experts. 01:46.737 --> 01:49.455 You'll also find that just like the real exam, 01:49.584 --> 01:53.076 our mock exam series uses multiple Kubernetes clusters. 01:53.424 --> 01:55.075 There are four clusters in total, 01:55.155 --> 01:58.761 some of which are dedicated to specific knowledge areas. 01:58.888 --> 02:01.684 By default, the exam taker, which is you, 02:01.764 --> 02:04.824 will be locked into what is known as the student node, 02:04.904 --> 02:08.735 and from here, you will be able to access all the other Kubernetes clusters 02:08.815 --> 02:13.169 and also be able to SSH to individual nodes of these clusters. 02:13.827 --> 02:18.036 In total, there are 20 random questions generated for the entire lab. 02:18.245 --> 02:19.499 As I mentioned earlier, 02:19.585 --> 02:22.944 these are randomized across the knowledge areas or sections, 02:23.032 --> 02:26.627 and you will have in total two hours to complete this exam. 02:27.446 --> 02:30.829 At the end of the exam, the results will be auto-validated, 02:30.941 --> 02:33.182 and you will be presented with a score. 02:33.629 --> 02:38.129 All right, that was a quick introduction to the ultimate CKA mock exam series. 02:38.220 --> 02:42.212 Let's now jump right in and go over one of these tests ourselves. 02:43.837 --> 02:47.957 All right, let's now start and take one of the mock exam tests 02:48.037 --> 02:50.049 that's included in this course. 02:50.259 --> 02:52.206 I'm going to click on start course 02:52.428 --> 02:56.574 and here you can see that we have in total 10 mock exams. 02:56.692 --> 02:59.202 All of them are randomized and for this demonstration, 02:59.282 --> 03:02.466 let's make use of CKA Mock Exam 1. 03:03.108 --> 03:05.132 Once you click on this lab, 03:05.260 --> 03:07.853 the lab should load up within 30 seconds. 03:07.962 --> 03:11.115 An average of one to two minutes is to be expected, 03:11.195 --> 03:15.160 but more often than not it should load within 30 seconds. 03:15.294 --> 03:17.705 There you have it, the first lab has been loaded. 03:17.795 --> 03:21.174 Here, you can see that we have in total 20 questions. 03:21.566 --> 03:23.172 The very first question is 03:23.252 --> 03:26.182 from the section architecture install and maintenance. 03:26.308 --> 03:30.700 If you remember, it accounts for 25% of the questions. 03:30.796 --> 03:33.794 For the first question, we have to set the context to cluster3. 03:33.875 --> 03:36.343 Before we begin, let me show you all the clusters 03:36.423 --> 03:37.827 that are currently configured. 03:37.932 --> 03:41.156 As you can see, we are currently on the student node. 03:41.369 --> 03:43.366 To check all the clusters that are configured, 03:43.446 --> 03:50.329 you can use the command kubectl config get-clusters. 03:50.978 --> 03:54.072 As you can see here, we have four clusters in total 03:54.152 --> 03:55.503 and by default 03:55.633 --> 03:59.750 if you do not set any context, you should be accessing the cluster1. 04:02.961 --> 04:04.303 As you can see, cluster1, 04:04.383 --> 04:09.383 which has got two worker nodes, which is cluster1-node01 and node02. 04:10.235 --> 04:12.735 In this case, we have to make use of cluster3. 04:12.932 --> 04:17.736 I'm going to copy this text here and paste it in this student node. 04:18.080 --> 04:20.806 Remember, student node itself is just a client 04:20.886 --> 04:22.542 where you'll find that you'll log in. 04:22.622 --> 04:25.629 If you open a new terminal, you'll also log to student node. 04:25.971 --> 04:29.638 If you want to access any of these control planes specifically, 04:29.721 --> 04:31.963 we'll have to make use of the SSH command. 04:32.140 --> 04:35.116 Now, I have set the context to cluster3, 04:35.196 --> 04:37.687 and if I run the same command as before, 04:38.082 --> 04:40.019 you'll see that this is a single node cluster 04:40.099 --> 04:41.720 with just one control plane. 04:41.801 --> 04:44.020 It's cluster3-controlplane 04:44.194 --> 04:47.098 and the version is 1.24 as of this recording. 04:47.627 --> 04:50.959 Similarly, you can set context for each of the question 04:51.039 --> 04:53.871 and that's something that I highly recommend that you do. 04:53.955 --> 04:58.307 Each question will make sure that you try to access the correct cluster 04:58.387 --> 04:59.925 by setting the context. 05:00.047 --> 05:02.593 In this case, let's read the question. 05:02.673 --> 05:09.587 We have to decode the existing secret, which is called beta-sec-cka14-arc 05:10.056 --> 05:11.899 created in a separate namespace. 05:12.063 --> 05:14.156 Let's attempt this question first. 05:14.379 --> 05:17.880 I'm just going to check if this namespace exists. 05:21.583 --> 05:24.236 As you can see, we do have that name space. 05:25.052 --> 05:29.364 I'm going to type kubectl get secret -n. 05:30.707 --> 05:34.157 Here you can see that that secret does indeed exist. 05:34.238 --> 05:37.960 Let me get it in a yaml format so that we can see the data. 05:40.308 --> 05:44.952 Here you can see that the secret is stored here 05:45.032 --> 05:46.611 under the data section. 05:46.726 --> 05:50.247 What I'm going to do is I'm just going to base64 decode it 05:50.328 --> 05:51.749 and put it in that file. 05:52.081 --> 05:55.363 I'm going to echo this particular string here 05:57.795 --> 06:01.480 and base64 -d. 06:02.736 --> 06:05.178 All that it says is, this is the secret. 06:05.259 --> 06:10.031 Now, what we can do is we can redirect that directly onto that file. 06:10.112 --> 06:12.922 Remember, this says that it has to be stored on the student node 06:13.003 --> 06:14.824 so I'm already on the student node, 06:14.904 --> 06:19.359 so I'm just going to redirect the decoded secret to this file, 06:21.015 --> 06:22.256 and that should be it. 06:22.397 --> 06:25.152 Now, I'll just scroll to the rest of the questions 06:25.232 --> 06:28.081 and show you the different sections that they belong to. 06:28.184 --> 06:31.493 As you can see, the first question was of weightage eight 06:31.630 --> 06:36.063 and belonged to the section architecture install and maintenance. 06:36.200 --> 06:39.597 The second question is of weightage two also belonging to the same section. 06:39.769 --> 06:40.988 Let's just scroll on. 06:41.083 --> 06:43.603 Just like any of our current mock exams, 06:43.683 --> 06:46.181 you can scroll back and forth between questions, 06:46.701 --> 06:49.350 but only thing to note is that you have to complete the test 06:49.430 --> 06:50.955 within the allotted time. 06:51.051 --> 06:52.051 If you run over, 06:52.131 --> 06:55.244 it'll automatically end the exam and validate it for you 06:55.324 --> 06:56.767 but at any given point in time, 06:56.847 --> 06:59.223 you can choose to click on the end exam button 06:59.303 --> 07:01.533 and see the score for yourself. 07:01.865 --> 07:04.394 The third question is also from the same section 07:04.559 --> 07:06.317 so is the fourth, 07:06.418 --> 07:08.502 and the fifth one as well. 07:09.029 --> 07:13.086 Now the sixth question, as you can see, is from the troubleshooting section. 07:13.166 --> 07:16.657 If you remember, this section is one of the largest for CKA 07:16.767 --> 07:19.380 and accounts for 30% of the questions 07:19.599 --> 07:22.731 and moving along you should find that the next question 07:22.811 --> 07:24.683 is from a different section 07:24.764 --> 07:27.676 and this case, as you can see this is from the scheduling section. 07:27.757 --> 07:31.087 Similarly, you'll find other questions belonging to other sections 07:31.167 --> 07:33.959 such as storage and networking in the test. 07:34.561 --> 07:39.374 Once you're happy with your attempt, you can click on the end exam button 07:39.549 --> 07:42.603 and this should automatically trigger the validation. 07:42.698 --> 07:45.243 In this case, I've attempted only the question one, 07:45.323 --> 07:47.977 so everything else will be marked as incorrect 07:48.057 --> 07:52.163 but I just wanted to show you how to navigate the mock exam series. 07:52.543 --> 07:55.622 Once this is done, I want to reload this lab again 07:56.533 --> 08:01.205 and show you that the next attempt can be completely different. 08:01.951 --> 08:05.829 Here I am trying to launch the Mock Exam 1 again, 08:06.017 --> 08:07.660 so let's do that. 08:08.876 --> 08:12.353 All right, so the CKA Mock Exam 1 is loaded again. 08:12.583 --> 08:14.618 Now, if you remember in our first attempt, 08:14.698 --> 08:17.642 the first question was to decode the secret. 08:17.722 --> 08:19.232 Now it's completely changed. 08:19.348 --> 08:20.949 This is completely expected. 08:21.029 --> 08:23.138 All of the questions are randomized, 08:23.218 --> 08:27.153 so you can expect different questions each time you attend the same lab. 08:27.370 --> 08:30.164 Now, if you're not sure what the solution is, 08:30.252 --> 08:33.423 the solution will be provided for you at the end of the exam 08:33.503 --> 08:34.892 during the grading process. 08:35.034 --> 08:38.203 For example, I did not attempt the first question this is wrong, 08:38.284 --> 08:40.948 so you will be provided with the solution immediately. 08:41.368 --> 08:45.842 In case you are stuck, make sure that you go over the solution that is provided 08:46.055 --> 08:48.679 and then you can try to take the test again. 08:49.054 --> 08:53.010 That was a quick demonstration of the ultimate CKA mock exam series. 08:53.091 --> 08:57.708 I hope that you find this really useful and best of luck with your preparation. 08:57.918 --> 08:58.757 Thank you. 08:58.838 --> 09:02.343 [music]
