RHCE i.e. RedHat Certified Engineer is considered as most respected certification in Linux Community. The certification actually consists of three Modules viz. SA1, SA2 and SA3. Any person who wish to get RHCE certified needs to clear two exams.
They are:
1) RHCSA i.e. RedHat Certified System Administrator which comprises of two Modules SA1 and SA2.
2) and RHCE which comprise of Third Module i.e. SA3.
There are many and immediate job openings in some of the well known Information Technology firms of India like Infosys, TCS, TechMahindra for those who clears RHCE exam and also for those who possess knowledge of RHCE.
Below are the topics (course content) discussed in all the three Modules (Official Curriculum) RHCE 6
