RHCSA/RHCE Tutorials, Objectives and Exam Information

This article provides RHCSA/RHCE tutorials, objectives and exam information. To assist you in preparation of the RHCSA/RHCE exam, RHCSA/RHCE objectives are explained individually in their respective RHCSA/RHCE tutorials.

RHCSA and RHCE are performance based exams. It means candidates are required to perform tasks similar to what they must perform on the job. These tasks are used to evaluate candidates’ skills and knowledge about Red Hat Enterprise Linux system.

Exam info

Both exams are presented in electronic format on a live desktop computer running Red Hat Enterprise Linux 7. This desktop computer will have one RHEL7-based virtual machine for the RHCSA exam and two for the RHCE exam.

In both exams, candidates are not allowed to access Internet and outside materials. But they are allowed to use the documentation that ships with RHEL. Time duration for RHCSA and RHCE are 2.5 hours and 3.5 hours respectively. Exam fees for both exams are same. Whether you take RHCSA exam or RHCE exam, it is 15,000 INR (400 USD).

Prerequisites for RHCE

In order to achieve RHCE credential, candidates are also required to pass RHCSA. Although a candidate can take the RHCE examination without passing the RHCSA examination, but his certificate will be issued only when he will also pass the RHCSA examination. In such a case, RedHat retains the candidate’s RHCE certificate and issues it with RHCSA certificate once it is earned at a later date.

Scoring and reporting

Exams results are declared by Red Hat Certification Central. Examiners or training partners are not authorized to report results to candidates directly. Exam results are usually reported within 3 U.S. business days.

Audience

Any experienced Linux IT professional/system administrator or network administrator can take these exams. Although experience is not a mandatory requirement for these exams, still it is highly recommended to take these exams only if you have one or more years’ experience in Linux.

Since I continuously prepare/update RHCSA/RHCE tutorials, some RHCSA/RHCE objectives are not linked with RHCSA/RHCE tutorials. If any RHCSA/RHCE objective is not linked, its mean either a tutorial for that objective has not prepared yet or it has become outdated. Such objectives will be linked, as soon as their respective tutorials are prepared or updated. Meanwhile you can check RHCE study guide section which contains all RHCSA/RHCE tutorials including outdated and archived.
