Let 's go through the Objectives we have to achieve to get to our goal. First milestone is Red hat System Administration (RCHSA); which is an individual certification offered by Redhat. One must have this certification in order to appear for RHCE exam.
So as a summary we have below scenario:
RHCE

RHCSA

ME
Redhat offers a combination of both tests RHCSA(EX200)+ RHCE(EX300) or you can first opt for "System Administrator"(SA) and then "Engineer"(E). In my preparation, I will be covering each aspect of both Certifications to get more clarity of the concepts and skill required.
First lets go with the path of RHCSA.
