RHCE Certification Lab (RH299)
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.
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.
Who should attend
- RHCEs on Red Hat Enterprise Linux 6 or earlier who wish to recertify on Red Hat Enterprise Linux 7
- Students who previously attempted the RHCE exam, did not pass, and wish to retake the exam
- Students who have completed the RHCE track courses (Red Hat System Administration I, II, and III or equivalent) and would like additional hands-on practice prior to taking the RHCE exam
- Students should have already completed Red Hat System Administration I, II, and III or equivalent training.
- It is highly recommended students take our online skills assessment prior to enrolling in this course.
- Extensive UNIX administration experience by itself is not adequate for most students.
