RHCT certification was being offered on RHEL 5. With the release of RHEL 6, RHCT has now been replaced with RHCSA (Red hat certified system administrator). Previously with RHEL 5, the RHCE certification exam would also test the RHCT part of the requirements. But now with RHEL 6, we have to take both the exams separately i.e. RHCSA and RHCE (can be done on the same day). There is no strict rule on the order in which one takes the exam; however, one must clear the RHCSA before he will be awarded the RHCE certificate.
In short, RHCSA is the entry level exam on RHEL 6. And as per the red hat website
- Red hat system administrator I
- Red hat system administrator II
are the recommended courses for preparation.
