A course with a very good content. However, I would like in each section apart from the lab sessions to be available also home exercises with common-real world tasks/problems where we will have to use the content of one or more sections in order to resolve them. BR Ioannis

The course presentation is clear, would be more better if give idea of application cases.

By Chris N on 8/24/2019

This is an excellent course for Linux, certainly one of the most comprehensive on Udemy. Mr. Verma is an excellent teacher also he is responsive to questions in this course and his others. After listening for a few minutes you get used to his accent. If you want to learn redhat/centos 7 you should take this course. You also need to purchase part 1 to get the full instruction for the Rhcsa.

Presentation skills of the instructor are very poor

By Dhimant Thanki on 4/7/2019

Overall, a very great course !! Concepts like SELinux, samba server and systemd topics explanations are in very depth and got a crisp understanding. All topics were greatly explained except LVM.

By Hashmi on 2/15/2019

Whether you are a complete beginner or you have knowlegde on linux,this course will help you to grow your linux skills.The instructor is very good and each tutorial is very in depth....His explanations followed by hands-on examples make this a course applicable to Linux administration.

By Chris Papas on 10/5/2018

I was a little scared at first taking any Red Hat Administration courses. But after starting this course, The Instructor quickly calmed my fears He delivered a clearly explanation in each section on all the material Making the Topics easily to be understood, with very explained detailed explanations that puts you at ease. I recommend this course to other students, who want to learn as I did very difficult Topics, that were very easily explained and understood.

By Jyoti Verma on 7/10/2018

Great efforts by Instructor to design such a nice course module for Learning Linux, now we don't need to go to Institute to Learn Linux for rhce certification

By Alexander Orlovsky on 7/8/2018

I admit , i didn't spent much time in exercises with this course, for me it was like overview of some cool RHEL features like LVM partition management from console, configuring your firewall , creating cronjob and customizing the acl (access list), creating soft/hard links most things are which devops nowadays are doing, so if you are want to be a devops you need this course , for java devs i really not sure what you get but it's fun this is definitely the case. IF you have official RHEL cert books then notice following topics are not covered in this course: Network Configuration with Troubleshooting Managing SELinux Tuning and Maintaining the Kernel System Recovery Techniques Conclusion: i give 3 starts because of a strong accent and the subs quality and feeling that some topics were not prepared well, but for people who did already previous Linux courses this is actually a great course.
