Kurs: Red Hat Certified System Administrator (RHCSA ) exam (EX200)

To earn RHCSA credential, candidates must demonstrate the skills required to be a successful Linux administrator through a hands-on, half-day exam (EX200).

An RHCSA certification is required in order to earn Red Hat Certified Engineer (RHCE).

Exam requirements:

The RHCSA certification exam consists of one half-day session. The exam is performance-based, meaning that candidates must perform tasks on a live system, rather than answering multiple choice questions.

It also provides more specific information on the exam format and coverage. All candidates are urged to use this information to evaluate their readiness for the exam.

Candidates will be emailed exam results within three US business days following the exam.

Preparation:

Red Hat offers clear training paths for candidates to learn the required skills.

Red Hat training courses provide hands-on labs and task-focused activities balanced with facilitated discussion to help course participants build essential skills quickly and effectively. Candidates are advised that real-world system administration experience is also an important aspect of preparation for the exam.

Red Hat Certified System Administrator (RHCSA) Exam Overview and Objectives

Overview

This guide provides information candidates may use in preparing to take the RHCSA exam. Red Hat is not responsible for the content or accuracy of other guides, books, online resources, or any other information provided by organizations or individuals other than Red Hat Training and Certification. Red Hat reserves the right to change this guide when appropriate. Candidates who have enrolled in forthcoming classes or exams are advised to check this guide periodically for changes.

Prospective employers of RHCSAs should verify any and all claims by people claiming to hold this certification by requesting their certificate number and verifying it here.

Performance-based Exams

The Red Hat Certified System Administrator exam is a performance-based evaluation of Red Hat Enterprise Linux system administration skills and knowledge. Candidates perform a number of routine system administration tasks and are evaluated on whether they have met specific objective criteria. Performance-based testing means that candidates must perform tasks similar to what they must perform on the job.

Authorized Training Partners

Only Red Hat and Red Hat Certified Training Partners administer the RHCSA exam. Prospective candidates should exercise due diligence when purchasing a seat in an RHCSA exam from a provider other than Red Hat itself. They should verify that the provider is, in fact, an authorized training partner or reseller in good standing. Please notify greymarket@redhat.com about organizations that purport to offer the RHCSA exam but are not Red Hat Certified Training Partners.

Scores and Reporting

Official scores for the RHCSA exams come exclusively from Red Hat Certification Central. Red Hat does not authorize examiners, training partners or other departments or individuals within Red Hat to report results to candidates. Scores on the exam are reported within three (3) US business days.

Exam results are reported as section scores. Red Hat does not report performance on individual items, nor will it provide additional information upon request.

Format of the RHCSA Exam

The RHCSA 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 included.

Preparation for the RHCSA Exam

Red Hat encourages all candidates for RHCSA to consider taking one or more of its official training courses to help prepare. Attendance in these classes is not required, and one can choose to take just an exam. Many successful candidates who have come to class already possessing substantial skills and knowledge report that the class made a positive difference for them.

To help you determine the best courses to take, Red Hat provides online skills assessment.

While attending Red Hat\'s classes can be an important part of one\'s preparation, attending class does not guarantee success on the exam. Previous experience, practice, and native aptitude are also important determinants of success.

Many books and other resources on system administration for Red Hat\'s OS products are available. Red Hat does not officially endorse any as preparation guides for any exams. Nevertheless, you may find additional reading deepens understanding and can prove helpful.
