RHCE Certification Lab (RH299)

This course is for individuals seeking a hands-on, lab-based review prior to taking the Red Hat Certified Engineer (RHCE) exam. Individuals taking this course should have already completed their classroom training and simply be preparing to take or retake the exam. During this course, you will work at your own pace through the complete set of labs from both the RHCSA [Red Hat Certified System Administrator] Rapid Track course (RH199) and Red Hat System Administration III (RH254).

This course includes a few instructor lectures designed to review key technologies such as systemd, firewalld, and IPv6. For the classroom and virtual classroom versions of this course, an instructor will be available throughout the week to assist you as you work through the labs. This version of the course does not include the Red Hat® Certified System Administrator (RHCSA) EX200 or the Red Hat® Certified Engineer (RHCE) EX300 exam.
