  • Impact on the organization

    This course is intended to develop the skills needed to extend, automate, and better secure an existing Red Hat Enterprise Linux deployment. It is designed as a natural extension of the RH124 course and introduces advanced file-system management capabilities, security controls, and firewall configuration.The skills developed in this course could lead to improved infrastructure performance, increased system utilization, and responsiveness to system failures. A better understanding of Linux file system and logical volume management should result in lower storage costs and better use of existing storage solutions.

    Red Hat has created this course in a way intended to benefit our customers, but each company and infrastructure is unique, and actual results or benefits may vary.

    Impact of this training

    As a result of attending this course, students should be able to perform the key tasks needed to become a full-time Linux administrator.
