[Qualification] I passed LinuC Level 1, so I will write about how to study and how it was.

The other day, I took LinuC Level 1 and successfully passed both 101 and 102 exams, and I got LinuC Level 1 on a sunny day.

What is LinuC?

It is a qualification that contributes to the growth of Linux engineers. Level1 (101, 102), Level2 (201, 202), Level3 (300, 303, 304) are divided into levels, and the difficulty level changes for each. After Level 2, you need to pass a lower level, so let's start studying from Level 1.

Official Examination Site An overview is available on the official website!

Introduction of contents of LinuC Level 1

This is a level test created for the purpose of building, operating, and managing a Linux system. If you do not pass both the 101 and 102 exams, you will not be certified as Level 1. By the way, one exam costs about 15,000 yen, so study so that you don't fall!

When you study Level 1, you will learn the following things.

--You can perform basic Linux operations and system management required in practice. --You can perform necessary operations and system management to build, operate, and maintain a Linux server environment. --You have the necessary knowledge to use a Linux distribution. ――You can check and learn basic Linux operations that you do not know and must remember.

The exam time is 90 minutes, the number of questions is 60, and if you get more than 60%, you can pass. You can take the test at test centers nationwide, and the result will come out immediately after answering the question. (Honestly, I'm scared when I press the last send button w)

The above is partly excerpted from the official website.

Why did you decide to take it

――I wanted to be able to efficiently investigate and investigate the cause when dealing with infrastructure failures. ――I wanted to firmly remember the commands (especially optional) that I usually typed without understanding the meaning. ――I wanted to establish knowledge by connecting lines that I remembered only in terms of points ―― ~~ (And I didn't want to lose because my juniors would receive it) ~~

How to study

First of all, I aimed to pass 101. I bought a book, read it all over, and if there was a command I was interested in, I actually typed it on my PC. There are exercises on the way, but there are also writing problems in LinuC, so there is a high possibility that you will forget it unless you actually hit it ...

Then I used Ping-t to make all 101 range problems gold. When making gold, the first copper → silver answered the question, then looked at the answer and explained it, and then brought it all to silver, and then silver → gold answered everything without looking at the answer and made it gold. At this time, if you answer with ** 20 question set ** as a recommendation, I think that you can look back immediately without sagging.

When all are gold, a mock test will be conducted. The mock exam is a set of 60 questions randomly given from all the questions. In my case, the correct answer rate was about 80% to 100%. Although it is a mock exam, in the case of Ping-t, the descriptive formula is not included in the question, so in the exam on the day, I think that the correct answer rate will be about 10% to 15% lower than the correct answer rate of Ping-t. .. Therefore, if the ** deadline is below 75% **, it seems suspicious to pass the day ...! (It's just an individual impression)

I did the same study method for 102. Since 102 has many test questions that are written by experience, I think that it is better to actually look at the Linux environment and study.

By the way, Ping-t also has a content called frame question (is it an abbreviation for command problem?), But I didn't do much. Rather than that, I think it would be better to actually type commands and check files at the terminal of a Linux machine (I was a Mac) and check files, which would be a good learning experience and two birds with one stone. I will.

Finally, the text purchased below [Shortest breakthrough LinuC level 1 pass textbook [101 exam, 102 exam correspondence]](https://www.amazon.co.jp/%E6%9C%80%E7%9F%AD%E7%AA%81%E7 % A0% B4-LinuC% E3% 83% AC% E3% 83% 99% E3% 83% AB1-% E5% 90% 88% E6% A0% BC% E6% 95% 99% E6% 9C% AC- 101% E8% A9% A6% E9% A8% 93-102% E8% A9% A6% E9% A8% 93% E5% AF% BE% E5% BF% 9C / dp / 4297106590 / ref = sr_1_1? __mk_ja_JP = % E3% 82% AB% E3% 82% BF% E3% 82% AB% E3% 83% 8A & keywords = linuc & qid = 1580377639 & sr = 8-1)

What was useful after passing

My usual job is as an engineer manager, so I don't do crunchy coding, but when it comes to troubleshooting, it's different. As an emergency response, we will move to respond as soon as 1 minute and 1 second from the cause of the failure. After all, I have the impression that whether or not you know the command for the investigation will change significantly.

Also, because I understand the Linux system, I was able to use it to investigate the cause when an error was thrown out when installing a package.

Summary

I think it's better to consider these kinds of qualifications as the main purpose of becoming yourself rather than passing the test. However, for various reasons, you have to pass the qualification to go, or as a confirmation of ability At that time, if you study with reference to this article, I think that you will be able to pass and study.

Have a good Linux life!
