Certification Path Changes
With the arrival of RHEL 7, the Red Hat certification paths have slightly been modified.
The RHCSA Rapid Track course (RH199/200) prepares seasoned administrators for the RHCSA 7 exam.
The RHCE Certification Lab (RH299/300) is geared towards very experimented administrators preparing both RHCSA 7 and RHCE 7. This course allows students to practice many topics in a lab with the help of an instructor. Red Hat recommends following this course before taking the exams.
