RH124 - Red Hat System Administration I

Red Hat System Administration I (RH124) is designed for IT professionals without previous Linux system administration experience. The course provides students with Linux administration "survival skills" by focusing on core administration tasks. This curriculum also provides a foundation for students planning to become full-time Linux system administrators by introducing key command-line concepts and enterprise-level tools.


IMPACT ON THE ORGANIZATION

This course is intended to develop the skills needed for basic administration and configuration of Red Hat Enterprise Linux. This course introduces key command line concepts and enterprise-level tools, laying the foundation for the rapid deployment of Red Hat Enterprise
Linux. The curriculum also introduces the basic administration skills needed for resolving configuration issues and integrating Red Hat Enterprise Linux systems with other existing environments. This offering lays the foundation for secure user and group administration, and
develops skills that allow administrators to use available storage solutions more efficiently and securely. This course is the first of a two-part series that takes a computer professional knowing nothing about Linux to being a fully capable Linux administrator.
