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.
Study Points for the RHCE Exam
Prerequisite skills for RHCT and RHCE
Candidates should possess the following skills, as they may be necessary in order to fulfill requirements of the RHCT and RHCE exams:
use standard command line tools (e.g., ls, cp, mv, rm, tail, cat, etc.) to create, remove, view, and investigate files and directories
use grep, sed, and awk to process text streams and files
use a terminal-based text editor, such as vi/vim, to modify text files
use input/output redirection
understand basic principles of TCP/IP networking, including IP addresses, netmasks, and gateways
use su to switch user accounts
use passwd to set passwords
use tar, gzip, and bzip2v
configure an email client on Red Hat Enterprise Linux
use mozilla and/or links to access HTTP/HTTPS URLs
use lftp to access FTP URLs

Troubleshooting and System Maintenance
RHCTs should be able to:
boot systems into different run levels for troubleshooting and system maintenance
diagnose and correct misconfigured networking
diagnose and correct hostname resolution problems
configure the X Window System and a desktop environment
add new partitions, filesystems, and swap to existing systems
use standard command-line tools to analyze problems and configure system
Installation and Configuration
RHCTs must be able to:

implement a custom partitioning scheme
configure printing
configure the scheduling of tasks using cron and at
attach system to a network directory service, such as NIS or LDAP
configure autofs
add and manage users, groups, and quotas
configure filesystem permissions for collaboration
install and update RPMs
properly update the kernel RPM

RHCE skills
Troubleshooting and System Maintenance
RHCEs must demonstrate the RHCT skills listed above, and should be able to:
use the rescue environment provided by first installation CD
diagnose and correct bootloader failures arising from bootloader, module, and filesystem errors
diagnose and correct problems with network services (see Installation and Configuration below for a list of these services)

Configure host-based and user-based security for the service
RHCEs must also be able to:

Red Hat Courses Covering These Skills
RH033 Red Hat Linux Essentials covers prerequisite skills, with the exception of TCP/IP fundamentals. The Network Essentials series covers TCP/IP fundamentals
RH133 Red Hat Linux System Administration covers RHCT-level skills.
RH253 Red Hat Linux Networking Services and Security covers RHCE-specific skills in networking services and security. Attendees should attend RH133 first.
Red Hat RHCE Fast Track Course condenses material from RH133 and RH253. Only experienced Linux and UNIX system administrators with background in networking services should attend.
