This course features a high practical content and will be delivered at a fast pace with a strong emphasis on using the command line. Delegates should have previous command line experience of LINUX/UNIX, including but not limited to; cp, grep, mkdir, vi, ssh, tar, gzip, useradd and be capable of using man pages.

The delegate will learn modern system administration techniques and commands to administer a Red Hat Linux system. The command line is demonstrated and used extensively throughout the course.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

The delegate will learn and acquire skills as follows:

• Managing files and directories via the command line
• Using system manual pages and documentation
• Configuring IPv4 and IPv6 Network Interfaces
• Configuring the Network Time Protocol
• Creating and managing users and groups

This FastTrack Red Hat 7 System Administrator course is suitable for experienced LINUX/UNIX System Administrators who need to acquire knowledge of the key administrative tasks required to administer a Red Hat Enterprise Linux (RHEL) system.

On completion of the FastTrack Red Hat 7 System Administrator course, the delegate will have a greater technical awareness of the system and will have acquired practical experience of the key administration tasks required to administer a Red Hat Linux system.

This FastTrack Red Hat 7 System Administrator training course will aid the delegate to work towards achieving the following exam:

• Red Hat Certified System Administrator (RHCSA): EX200

Please note, Red Hat certification is only available for RHEL 8 and all exams are performed on RHEL 8.

Attending this course will help the delegate gain many of the skills and product knowledge requirements as outlined in the exam objectives. Studying this course and its associated reference materials can form part of the preparation to achieve certification. Experience, practice, self-study and aptitude are also key requirements for exam success.

Before taking any exam, ensure you have the recommended experience. The Red Hat website lists all exam requirements and these are updated regularly.

Exams are not included as part of the course.

This course assumes a strong prior knowledge of the Linux operating system, and significant experience working with Linux as a system administrator is r ecommended.

The delegate will be expected to already understand fundamental Linux computing concepts, to the level covered on the Red Hat 7 System Administration - Part 1 course, as a minimum level requirement for attendance.
