The RHCE^® Certification lab (RH299) is designed for students seeking a hands-on, lab-based review prior to taking the Red Hat Certified Engineer (RHCE) exam. Students taking this course should have already completed their classroom training and simply be preparing to take or retake the exam.

Ways To Train/Test
Red Hat offers a method of training that is convenient to you - classroom, or at your site.

Course overview
During the 4-day course, students will work at their 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). The RHCE Certification Lab 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 students as they work through the labs.
