Hello everyone, I am RHCE who registered at 51CTO in 2022. I have not taken the exam before because of work reasons, so I take advantage of this vacation, I concentrated my time on sprinting, preparing for the exam for more than a month, and finally RHCSA: 286 RHCE: 260 successfully obtained the certificate.
The simulation environment prepared by Mr. Geng is very perfect, so we should use the simulation environment to practice more. We should be strict with ourselves when we practice, and try to achieve full marks. When we score, we should see what we have done wrong, and then study why we have done wrong Measure the way to solve the problem, and check the details again and again. It is good to make mistakes in practice at ordinary times. More practice and more discovery of the points prone to mistakes can better help you avoid pitfalls in the exam. The week before the exam, I basically practice at least twice a day （CSA+CE） 。 You'd better understand the error information yourself. If you report an error during the exam, you can also find the problem in the yml file as soon as possible.
I was unlucky this time. In the afternoon RHCE exam, I got the questions for the parted module. The questions required mount mounting, but I was afraid that the mounting was wrong. Node5 could not be restarted. The whole exam was hung on the wall. So I chose a conservative approach, just partitioning and formatting, It is not attached, which means that "the exam is not attached"! Another question is about selinux roles, because the first question is ansible.cfg In the file, only one role path~/important/roles/was given, which led to the failure to find the corresponding roles available. Finally, two additional paths were added:/usr/share/important/roles/... and~/important/mycollections/ playbook， It is better to remember these two additional paths directly, and write them directly into the ansible.cfg file during the exam to save trouble. You can't run selinux.yml without writing!!!
In addition, the CSA in the morning encountered a new question, which is to set the user's default permission umask for creating files and directories. The new files created by the user are required to have r-r -- r -- permissions, and the directories created by the same user are required to have dr-xr-xr-x permissions. I am puzzled by this question, Because I was not sure, I did not dare to move in the end. I was afraid that the configuration file would be adjusted randomly, which would lead to other problems. For the sake of conservatism, I decided to give up this question. Finally, he scored 286 points. Finally, please review the questions carefully. There are some questions that are different from the requirements in the simulation environment, such as the question of generating the host file myhosts. In the exam, you don't need to write the yml file, just download the hosts.j2 and yml script file, and modify the template file. I wrote the yml file myself at first, and then found that the question requires only downloading and using the yml script, And its script file cannot be changed. Therefore, if you don't pay attention to the examination, you write your own script, which is inconsistent with the script given by the examination Points will also be deducted. I only got 260 points for CE, which is probably related to the mistakes in examination. I hope my exam experience will be useful to you. I wish you a smooth exam and full marks!
