RH133 - Red Hat Linux System Administration and RHCT Exam Training Seminar

Course Description

A Linux system administrator who has proven competency by passing the RHCT Exam, a realistic performance-based lab exam that tests his/her actual ability to install, configure, and attach a new Red Hat Linux system to an existing production network. Audience: Linux or UNIX users, who understand the basics of Red Hat Linux, that desire further technical training to begin the process of becoming a system administrator. Course Summary For users of Linux (or UNIX) who want to start building skills in systems administration on Red Hat Enterprise Linux, to a level where they can attach and configure a workstation on an existing network. This 4 1/2-day course provides intensive hands-on training on Red Hat Enterprise Linux 5, and includes the RH202 RHCT Certification Lab Exam on the last day. Those who are interested in taking the RH133 course, but who are not interested in RHCT certification or who feel they must defer the RHCT Exam to a later date may wish to consider RH131.
