Red Hat Services: Training & Certification: Exam Prep

 
Preparing for the RHCETM Lab Exam

The Red Hat Certified EngineerTM (RHCE) Exam stands apart from many other certification programs in the IT sector because of its emphasis on hands-on performance-based testing of actual skills in Red Hat Linux installation, configuration, debugging, and setup of key networking services.

RHCE Exam is a performance-based practical exam. Of the 6 hours allotted for the RHCE Exam, only 1 involves answering multiple choice questions. This is in contrast to the rest of the certification industry, in which multiple-choice questions are the norm.

Consequently, the first, last, and most important element of preparation for the exam is actual skills and experience using Red Hat Linux.
 
What are your experience levels?
The best way to prepare to take the RHCE Exam depends on your background and current experience level. Three types of prospectives are described:

1. You have lots of recent UNIX and/or Linux experience and networking experience:
If you are already an experienced system administrator for Linux/UNIX systems and also have experience at setting up essential network services, it is a good idea to to make sure your skills and experience encompass the scope of skills in the course outlines for RH300 RHCE Course.

2. You have some UNIX and/or Linux user-level experience, or you are MCSE, MCP, or CNE:
If you are not highly experienced in UNIX/Linux system administration and/or network services, or if your system administration experience has never involved UNIX or Linux, you may want to consider taking one or more of the skills courses in the RHCE Program: RH033, RH133, RH253, depending on your level of experience.

RH133 is the transition course for MCSE, MCP, and CNEs, as well as others who want a review of their UNIX user skills on Red Hat Linux. RH253 is for those who have the skills in RH133 but need to learn to configure key networking services and security. Persons taking RH253 should make sure they have taken Internetworking with TCP/IP or its equivalent from a reputable training vendor, or through self-study.

3. You are a Linux pro, expert, or already run your own ISP, or else you have really strong self-study discipline and access to a networked Linux server:
For those wishing to prepare for the RHCE Exam without taking RH300, or any other Red Hat course, the remainder of this document lists proficiencies that should be developed prior to taking the RHCE Exam. Red Hat reserves the right to change the elements of the exam at any time, with or without changes to this study outline.
 
Components of the RHCE Exam
The RHCE exam consists of 3 components:

I. Debug Exam: 2-4 challenges; 2.5 hours, performance-based (100 pts)
II. Multiple Choice Exam: 40-50 technical questions; 1.0 hour, multi-choice answers
III. Server Install and Network Services Setup Exam: 2.5 hours, performance-based (100 pts)

PASS requires: avg of 80 or higher, with no single score lower than 50 pts.

The Debug Exam involves correcting problems on a Red Hat Linux system. These problems range from boot failure to problematic network services. Examinees may use any documentation installed on the system in order to assess and correct problems, but they may not bring in any books or notes, and "reinstall" is not a valid corrective measure!

The Multiple-Choice Exam tests for technical knowledge about Red Hat Linux. It also includes questions that assess knowledge of common Linux commands, command redirection, and other system administration skills. No notes or books are permitted during administration of the multiple-choice exam, and examinees may not use computer resources (man pages, info pages, etc.) to gather information.

The Server Install/Network Services Exam requires examinees to install and configure a Red Hat Linux server on an x86 system. Configuration may include various network services, user environment, account management, and other elements that fall under the heading, "system administration". Precision and completeness are important for all tasks in this exam.

Red Hat stats show that it is quite easy to score high on the multiple-choice component of the RHCE Exam while being unable to score sufficient points on the performance-based components of the RHCE Exam. This illustrates the difference between multi-choice only certification and performance-based certification.
 
Study Points for the RHCE Exam
Red Hat cannot provide a laundry list of minute details about the RHCE exam. Persons who have taken the RHCE Exam have signed a Confidentiality Agreement not to share details about the RHCE Exam. The integrity of the RHCE Exam depends on the integrity of the community of persons who take the Exam.

Experienced Linux system administrators seeking to take the exam without preparing first through Red Hat's courses may find that the list below is a useful guide to preparation. Red Hat does not represent the list below as complete or comprehensive, and does not guarantee individual performance or results on the RHCE Exam based on this list.
