Trying to speak a high-level English, which is a little disturbing to bear The course is yet to start.
By Brett Pladna on 1/1/2020
This was a wonderful class. I also enjoyed the other 2 RHEL 7 SA classes. Thank you so much.
By Hamada Elmi on 8/15/2019
What did I said about him is true Mr. Shikhar Verma he studied everything about redhat, and he has a lot of experience in Linux, so if you want to be recieving Redhat certifications RHCSA EX200. Or RHCE EX300, then go learn from him and then go take the test and you will pass it for sure.

The course content is upto SA-3 RH254 but you missed maria DB services otherthan that course is good and your explanation is above my expectation
By Ramlala kumar on 6/14/2019
Explanation is very good
By Raymond Kayser on 4/12/2019
Excellent explanation of RHCE topics and even better demonstration of how to perform each of the task. I had a question about iSCSI and Shikhar responded with 24 hours of asking my question. He has been my "goto" for all things Linux and specifically RedHat. Look forward to finishing the rest of the course and taking some of his other courses.
