Red Hat RHEL7 RHCE certification study and examination experience

Red Hat RHEL7 RHCE certification study and examination experience
RHCE is an intermediate certification for the Linux system launched by RedHat. All the tests take the form of computers. It can examine the examinee's basic theoretical knowledge and practical hands-on operations, the value in the Linux field is undeniable. Therefore, it is necessary for students in the relevant industry to obtain the RHCE certification before taking up their posts, this article is mainly for those who have made up their minds to participate in the RHCE certification. Why is it called Pass-RHCE, according to the legend of the three axes, Cheng Zhijin was taught by a fairy while he was sleeping. Although there were not many tricks, they were very useful, and these three tricks became the trick of Cheng Zhijin, we hope that the three axes below will help you solve problems related to preparing for RHCE.

Pass-RHCE's "split head" -- select your "Weapon"

Ancient heroes usually have their own exclusive weapons, which can multiply their combat capabilities. For example, Qin shubao has a gold-plated pair of copper, Luo Cheng has a rolling cloud gun, and Cheng Zhijin has three axes, so to pass RHCE, You need to select a suitable "Weapon"-teaching material, and then read and understand this teaching material with a dedicated mind. I have many colleagues around me (to learn ), I have bought a lot of Linux reference books or many videos since I made up my mind to prepare for RHCE. I will take a look at this beginner book in three days and explain it to the great god in two days, but the final result is that there is no improvement in Linux technology. Therefore, those preparing for RHCE should remember this: "Never be too ambitious and be down-to-earth ". So are you reading your own books or purchasing videos? Video efficiency is very low. It is not suitable for those who have already gone to work or studied hard, and they are not very efficient to view teaching materials with their own aspirations, not even as good as the popular science RHCE certification posts I have seen on the Internet, because the texts are carefully written by the author, and there are often many "nonsense" videos ". Therefore, the recommended learning method is better to read books efficiently by myself. For RHCE teaching materials, although there are official RedHat reference PPT, there are various linux entry books on the market, however, I do not recommend you to read any of the above materials. First, we will talk about the official PPT. Although it is the official training materials of RedHat, it contains many professional words which we have not read yet, the major words that have already been used are confusing, while other entry books are either supporting teaching systems rather than RHEL7 systems certified by Red Hat RHCE, either the books are outdated and cannot keep up with the technologies in actual work. What I recommend to you is the Linux textbook "LINUX should be learned like this". This book covers the most basic installation of Linux systems and deployment of advanced services, the content fully includes all the knowledge points of the Red Hat RHCSA + RHCE Certification Examination, And it extracts the knowledge about Linux, saving a lot of time for the RHCE preparation, it has escaped the Fearless "pitfalls ". After talking about this, it is estimated that it will be regarded as an advertisement ~ If you are interested, you can download the pdf file of this book here. It is free of charge. In addition, this book is a free electronic version, and the author has been updating the book to ensure that the book is not out of touch with the production environment system, the most important thing is that this teaching material is a book using the Red Hat RHEL7 system as the teaching system, which is more suitable for our colleagues preparing for RHCE. Students can try to read several chapters to see if they meet their needs. I believe you will gain some benefits. If you find that it is not suitable for you, you can also find your own teaching materials, but if it is suitable for your own needs, please remember your advice and stick to it, I also thoroughly understand the knowledge points described in the teaching material, because every knowledge point in the book is tested by the RHCE certification!

Pass-RHCE's "" ghost teeth "" -- "" practice "" Let's know!

The next step is also very important. The last one is like the one that students learned about martial arts and obtained a secret from martial arts and martial arts. This one requires the knowledge of the Students in diligent exercises, first, install VMS or other virtualization software on your computer, and create an RHEL7 virtual machine and take snapshots. This is like the ancient heroes who have their own martial arts venues and can concentrate on martial arts. You can directly download the virtualization software and RHEL7 from the official website of the textbook I recommended, or solve the problem on your own. (Hey, do you still feel that the recommended textbook has many advantages ). With my own "", you can enjoy the pleasure of "". Some people may say why I want to practice. I have mastered the knowledge, is it okay to directly perform authentication? This idea is completely wrong, because the Red Hat certification is very focused on practical operation ability, different from the tests we took at school, the RHCSA exam in the morning, maybe you can take the test by luck, but the RHCE test in the afternoon takes a short time and has a large number of tasks. In addition, errors may occur after the configuration, and you need to eliminate the errors, configure the services correctly. In addition, preparing for RHCE is not only for the paper certificate, but also for better and faster work at work, as well as improving the ability to handle daily and sudden problems. For example, when I was preparing for RHCE, I encountered difficulties on the first day of the exercise (this is the result of not practicing, haha). At that time, I used to crack the password of the root account, this is also a very practical skill. When I read a book, I felt that all the steps and commands had been understood, and I felt that the task would be completed very smoothly, but the cruel reality has poured some cold water on me. Next I will post my operation steps:

In this case, I tried the command many times and never succeeded in modifying the command. The careful students certainly saw my problem at a glance, but at that time I did not respond, there is no way to return to the teaching material, so you can see that you have missing a command touch /. autorelabel, the role of this command is to override the security context of selinux, and I did not break into the system, resulting in a failure to crack the ROOT password. It is because I believe in my own judgment that this experiment fails, but I am lucky to realize the importance of this experiment for RHCE. Therefore, students must exercise more, for more experiments, see the configuration process in Linux!

Pass-RHCE's "ears"-secret of the test room

Finally, let's talk about the schedule of the RHCE test. In the morning, the RHCSA test takes two and a half hours, with a full score of 300,210. In the afternoon, the RHCE test takes four hours, pass the test with a full score of 300,210. In the morning, RHCSA is not very difficult. It is not a problem to pass the preparation. In the afternoon, the RHCE is a little difficult and requires strong operation capabilities. This is why I tell you that you must practice more. Ask the examiner for a blank A4 paper during the exam. You can write down important parameters on the paper, for example, the cracked ROOT Password (used repeatedly during the exam) or the answer ideas. In addition, you can go to the toilet during the exam. do not affect the exam on the day (sha), and then talk about the prohibited actions. The examiner is not allowed to see the relevant information/USB flash drive, otherwise, cheating is performed. Also, do not tamper with the questions to avoid hitting the network cable. During authentication, all operations on the RedHat are performed through the network, so the network cable is dropped, and the consequences can be imagined. Finally, let's get some benefits. The Beijing test site is at XX. After you hand in the paper in advance in the morning, you can go to dinner first, Because XX is also a place with many companies. There are a lot of people when there are meals, the delay also affects the mood, which is not good for the afternoon exam. Therefore, after completing the RHCSA exam, you can come out and have a meal first. Then, you can find a quiet place to review the RHCE exam in the afternoon.

The above are my three-point suggestions for students preparing to participate in the RHCE certification. Some suggestions may not be very comprehensive, but I hope they will help you get faster and more stable on the way to preparing for the RHCE certification, finally, we look forward to your successful RHCE certification, so that you can take the course of your business!
