Red Hat Certified Engineer (RHCE)
Launched in 1999, the RHCE certification is one of the most respected IT certification programs worldwide. Red Hat Certified Engineer (RHCE) is earned by a Red Hat Certified System Administrator (RHCSA) who has demonstrated the knowledge, skill and ability required of senior system administrator for Red Hat Enterprise Linux systems.
RHCE consists of one training module — namely, Red Hat System Administration III (RH254) — and successfully passing the examination. Although participating in the classroom training module is not necessary to sit for the certification examination, it guides you in your exam preparations.
Red Hat System Administration III
Red Hat System Administration III (RH254) is designed for experienced Linux administrators who require networking and security administration skills. With a heavy emphasis on practical, hands-on labs, this course is tightly aligned with experienced Linux administrators’ job tasks and the skills required for advancement.
Focus is placed on enhancing the students’ automation skills to securely configure, deploy and manage network services including DNS, Apache, SMTP, and network file sharing. In addition, this course emphasises security, including monitoring, packet filtering, access controls, and SELinux. At the completion of this course, students already familiar with the RHCT/RHCSA administration skills will have exposure to all competencies tested by the RHCSA and RHCE exams.

RHCE Certification Examination
To earn RHCE credential, candidates must demonstrate the skills required to be a successful Linux administrator through a hands-on, half-day exam (EX300). The exam is performance-based, meaning that candidates must perform tasks on a live system, rather than answering multiple choice questions.
Exam Format
The RHCE exam is a hands-on, practical exam that lasts 2.0 hours. Internet access is not provided during the exam. Outside materials are not permitted. Documentation that ships with Red Hat Enterprise Linux is available during the exam.
Recommended Preparation
We offer the following training modules are offered to learn the required skills:
- RH124: Red Hat System Administration I
- RH134: Red Hat System Administration II
- RH254: Red Hat System Administration III
Audience
- Experienced Linux IT professionals who currently have RHCSA certification, and are interested in earning an RHCE certification
- Experienced Red Hat Enterprise Linux system administrators seeking validation of their skills
- Students who have attended Red Hat System Administration I, II and III
- RHCEs who are non-current or who are about to become non-current and wish to re-certify
Fee: Rs 12,500/- + service tax
