RH300 RHCE Rapid Track Course Description

Goal:

A Red Hat Enterprise Linux system administrator who has been trained then tested by means of the RHCE Exam, a realistic performance-based lab exam that tests his/her actual ability to: install and configure Red Hat Enterprise Linux; understand limitations of hardware; configure networking and file systems; configure the X Window System; configure security, set up common network (IP) services, carry out diagnostics and troubleshooting, and perform essential Red Hat Enterprise Linux system administration.

Audience:

UNIX or Linux system administrators who have significant real-world experience with UNIX or Linux systems administration and some experience setting up key networking services such as HTTP, DNS, NIS, DHCP, and who want a fast-track course to prepare for the RHCE Exam.

Prerequisites:

RH033, RH133, RH253 or equivalent experience with UNIX; LAN/WAN fundamentals Internetworking with TCP/IP, knowledge or experience setting up NFS, HTTP, DNS, FTP, NIS, DHCP, and other networking services, and security.

To assist you in determining if you have sufficient system administration knowledge to take RH300, try taking the following pre-assessment questionnaires:

RH033 Pre-assessment Questionnaire
RH133 Pre-assessment Questionnaire
RH253 Pre-assessment Questionnaire

In order to ensure that the prerequisites for RH300 are met, you should expect to receive a high score for RH033 (36 points or more) and moderate scores for RH133 and RH253 (24 points or more each).

The prerequisites are important! Participants arriving without a large portion of these prerequisites will make less than optimal progress in the training and will be unlikely to pass the certification exam. Please do not sign up for RH300 unless you are experienced with systems administration or are a power user in UNIX / Linux environments If you need training on the above prerequisites.

Duration:

5 days ( 40 Hrs.)

Prepares for:

Prepares a server system administrator so that he/she is “ready from a technical point of view for professional responsibilities in managing a Red Hat Enterprise Linux system for common uses.”

What you will learn:

The following is an outline of the skills and knowledge represented in the training elements (four days) and in the Certification Lab Exam (one day) of the Red Hat Certified Engineer (RHCE™) course.

The RHCE training elements and Certification Lab Exam will also review and test on certain prerequisites for the course. The prerequisites for the RHCE course are outlined in a separate document, which should be carefully reviewed by anyone planning to attend an RHCE course.

The RHCE outline, together with the prerequisites outline, can serve as a study outline for those planning to attend the RHCE course and take the Certification Lab Exam. It is highly recommended that all prospective RHCE participants review these outlines in preparation for the course and exam.
