Prerequisites of RHCE

An RHCE is able to perform the following tasks (in addition to tasks associated with RHCSA):

Configuration of static routes, packet filtering, and network address translation

Setting kernel runtime parameters

Building simple RPMs

Configuring an iSCSI initiator

Producing and delivering reports on system utilization

Using shell scripting to automate system maintenance tasks

Configuring system logging, including remote logging

Configuring a system to provide networking services, including HTTP/HTTPS, FTP, NFS, SMB, SMTP, SSH, and NTP

There are 2 exams under RHEL 6

· RHCSA (RH 124 & RH 135)

EX 200- RHCSA Certification Exam

and

· RHCE(RH 254)

Ex 300-RHCE exam

In order to earn RHCE, one should pass the Red Hat Certified Engineer (RHCSA) exam. One is eligible to take the RHCE exam without first having passed the RHCSA exam, but RHCE will not be issued until both credentials are earned by a candidate

Prerequisite Skills:

For the RHCE and RHCT exams, the skills outlined in this chapter are generally minimum requirements. For example, while you may prefer to use an editor other than vi, you may not have access to the GUI, and therefore need to know how to use a console-based text editor on at least the Troubleshooting and System Maintenance section of the exam. While you're not required to know how to pipe the output of dmesg to the less command, this is a useful tool that can help you identify problems.
Remember that there are more ways than one to do most everything in Linux. While it's best if you learn all of these "prerequisite" skills, you don't have to know everything in this chapter. In most cases, it's okay if you use other methods of editing or otherwise configuring your RHEL 5 system. As the Red Hat exams no longer include multiple choice questions, don't worry about memorizing the dozens of switches used for certain commands. Focus on results, not trivia.
Using Other Versions of Red Hat
For those of you with more advanced hardware experience, the Red Hat exams are based on PCs built with Intel 32-bit CPUs. That means you'll be using the Linux kernel and associated software that has been customized for this CPU.
For the purpose of this chapter, you can use Fedora Core 6 or one of the rebuild distributions to test your knowledge of basic commands. In fact, the rebuild distributions are excellent, freely available options, as they use the same source code as Red Hat uses to build RHEL 5. One list of rebuild options is available at http://linuxmafia.com/faq/RedHat/rhel-forks.html.
