RHCE and RHCT Exam Preparation Guide
Overview

This guide provides information candidates may use in preparing to
take the RHCT or RHCE 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 Global Learning Services. Red Hat reserves the right to change
this Guide when appropriate, and candidates who have enrolled in
forthcoming classes or exams are advised to check this guide
periodically for changes.

The Red Hat Certified Engineer (RHCE) and Red Hat Certified Technician
(RHCT) exams are performance-based evaluations of Red Hat Enterprise
Linux and Red Hat 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.

Prospective employers of RHCEs and RHCTs should verify any and all
claims by people claiming to hold one of these certificates by
requesting their certificate number and verifying it here.

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

Official scores for the RHCE and RHCT exams come exclusively from Red
Hat Certification Central. Red Hat does not authorize examiners or
training partners to report results to candidates directly. Scores on
the exam are usually 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.
Preparation for the RHCT and RHCE Exams

Red Hat encourages all candidates for RHCT and RHCE to consider taking
one or more of its official training courses to help prepare for the
RHCE or RHCT exam. 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
have reported 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 to take the RHCE or RHCT exam, 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 the RHCT or RHCE exams. Nevertheless, you may
find additional reading deepens understanding and can prove helpful.
Components of the RHCE and RHCT Exams

The RHCT exam is a subset of the RHCE exam, and is organized as
follows:

* Troubleshooting and System Maintenance — 1 hour
* Installation and Configuration — 2 hours

In order to earn RHCT, one must successfully complete all the
requirements in Troubleshooting and System Maintenance, and must
achieve a score of 70 or higher on Installation and Configuration.

For RHCE exams given on Red Hat Enterprise Linux 3 and higher, the
exam is organized as follows:

* Troubleshooting and System Maintenance — 2.5 hours
* Installation and Configuration — 3.0 hours

In order to earn RHCE, one must successfully complete all the
RHCT-level Troubleshooting and System Maintenance requirements, and
successfully complete enough additional RHCE items to earn a score of
80 or higher overall on the section.

In addition, one must score 70 or higher on the RHCT items of
Installation and Configuration, and 70 or higher on the RHCE
components of that section. We describe the skills associated with
RHCT and RHCE below.

For RHCE exams given on Red Hat Linux 9, the following structure
applies:

* Troubleshooting — 2.5 hours
* Multiple Choice — 1.0 hour
* Installation and Configuration — 2.5 hours

In order to earn RHCE on these exams, one must successfully complete
all the RHCT-level Troubleshooting requirements, score a minimum of 50
on the multiple choice, score 70 or higher on both the RHCE and RHCT
components, and earn an overall score of 80 or better for the exam as
a whole.
