Wednesday just finished kubernetes of CKA certification, simply record yourself to some of the ideas from pro forma to the start of a friend in need.
The ending exam
I am ready to start this year off work in cka obtain certification, because I am a zero-based, all before the exam I first systematic study for three months, then brush the question practice for a month. If you are zero-based, it is recommended to learn about the system, do not just rely on the brush exam exam. This may not understand some details of the place, leading to failure of the exam. A total of three hours long exam, I spent more than two hours to complete the answer, in which a node expansion is particularly complex because so directly to give up, there is a troubleshooting did not do it. Two questions add up to a total of 12 points, but fortunately not a lot wrong in front of the title, the last score of 81 over the line.
Exam type:
CKA 24-question test total, out of 100 points, 74 points over the line. Score for each question is not the same, less simple question Score, difficult questions relative score is high.
The main types of questions percentage weights as follows:
● Application Lifecycle Management 8%
● installation, configuration and verification 12%
● Core Concepts 19%
● Network 11%
● Program 5%
● Security 12%
● cluster maintenance by 11%
● The recording / monitor 5%
● Storage 7%
Troubleshooting ● 10%
I feel passing the exam, the entire exam question is about 1/3 of the basis for comparison, only need a two commands to complete, or 1/3 is the need to have a solid basic skills to be able to complete, most of these questions yaml need to use to write, we need to create the syntax of various resources and master key, of course exams allow cka when the examination of official documents open kubernetes help Viewer. The remaining one-third is the difficulty of the exam, which is part of the problem, including expansion, safety certification, as well as troubleshooting and so on. You need to have a full understanding of the entire kubernetes cluster.
The entire exam k8s test environment is divided into several clustered environment, during the answer when the attention switches.
Exam Notes:
1. Register exam, your computer will be verified to see if the environment meet the test required, cka test requires the use of Google browser, detects when the environment will make you install a plug-IPS, it is through the examination papers this plugin issued.
2. Prepare a high-definition camera, full examiner will pass your camera to the examiner, the examiner will check your credentials before the opening test by a camera, preferably a passport, without a passport, driver's license ID card can be.
3. Try to choose an empty room, exam 15 minutes, the examiner will be for you to navigate through the dialog box before the start of issued instructions, including whether the test room there are other people, whether desktop has nothing to do with the examination of things. This time you will need to hold the camera will show the overall look of the room to the examiner, in addition to a desktop computer mouse do not have anything else.
4. Because the use of the test environment is abroad, so also prepare a stable ***, scientific online, they want a solution to this too. Before the opening test examiner will be asked to share your desktop through the IPS plug-in, and check your task manager, in Lite mode, Task Manager only allowed Google browser, which only allows the interface to open exam.
5. When the examination when I am using ubuntu 16.04 operating system, and version 1.15.0 k8s environment, over time, will gradually updated version of the exam, so I want to take the exam friends need to always pay attention to the official website version with k8s new information, see What are the differences between each version, including API interfaces, commonly used commands, as well as keywords when writing yaml file updates.
6. Examination of the time do not look around, do you think after the opening test examiner will not control you do, the whole examiner will observe you through the camera, and watch your computer's exam interface through shared desktop.
7. If your foundation is solid, the more skilled grasp the questions, usually two hours to complete all the questions, but it is recommended that you drink as little as possible before the exam.
8. The examiner will communicate with you in English through a browser dialog, basic Basic English are able to understand, if you really do not know also do not panic, typing directly with the examiner can not read English, he would use translation software to translate English into Chinese and then sent to you.
Stepped pit:
1. I have a problem because when the exam questions have not resulted *** decentralization, then the examiner let me keep clear the cache, and then I re-open due to personal subjective reasons want to close the browser, the results when I close the browser opens again interface when displaying the examination is over, then I can send mail to explain the situation to the test side, then quickly receive a mail with a link before landing once again start screen. This operation is a direct result of my delayed more than an hour, but fortunately, after the questions below to extend the examiner gave me more than an hour. So everyone in the exam try not to close the browser.
2. *** or questions *** Finally, I will shut up, just below the examination papers success, so I want to test friends in advance to prepare a stable ***.
3. The examination process because in their own thinking, habitual hand over her mouth, is getting a warning examiner's all we should not let any shelter in the mouth by the time of the examination.
