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.

In preparation to earn the Red Hat Certified System Administrator (RHCSA) Exam (EX200), Red Hat recommends the following:

• Red Hat System Administration I (RH124)
• Red Hat System Administration II (RH134)

After completing above two tracks( RH124 and RH134), one will be able to crack the 1st milestone i.e. RHCSA.
