RHCE (Fast Track) Rapid Track – 4 Days

Course Description

This course presents the working environment of a RHEL 7 system. It introduces commonly required operations that can be performed by entering commands interactively in a command terminal, along with functions available in the GNOME Desktop Environment . This course will concentrate on Red Hat Enterprise Linux (RHEL), version 7 (all update levels). This course is the equivalent of Red Hat course 199, to prepare for the RHCSA 7 examination.

Course Objectives

Each participant will be able to use RHEL 7 Bash Shell techniques and commands to maintain collections of files, create files using interactive editor utilities, create and execute basic command procedures, communicate with other users, and tailor the interactive environment to meet their needs. Major administrative features to setup and control a functioning RHEL 7 system will also be shown.

Prerequisites

This course is a concentrated preparation for the RHCSA 7 examination. Participants are assumed to be (Red Hat Enterprise) Linux system administrators working on production level configurations, and have used and demonstrated competencies in Linux fundamentals and entry-level administrative functions.
