Red Hat Linux

Red Hat Certified System Administrator (RHCSA) was launched in November 2010. It replaces the old Red Hat Certified Technician (RHCT) qualification.

The RHCSA exam (EX200) is 100% performance-based, coming after a review of the knowledge and skills required daily by today’s system administrators.

Since 2010, the RHCSA has been made a prerequisite for those taking the Red Hat Certified Engineer (RHCE) qualification.

Red Hat has announced a new addition to its line of performance-based certifications—Red Hat Certified System Administrator (RHCSA), which will replace Red Hat Certified Technician (RHCT).

one must earn RHCSA and pass a separate RHCE exam.

After passing RHCE one can take upper-level credentials such as Red Hat Certified Architect, Red Hat Certified Security Specialist, and Red Hat Certified Datacenter Specialist.

Beginning with Red Hat Enterprise Linux 6, candidates must pass both the RHCSA and RHCE exams in order to earn their RHCE. This is similar to the existing requirement that candidates pass both RHCT and RHCE components in the existing RHCE exam, except that the two exams are now separate.
