Linux System Administration On-Site Training

This Training course is heavily practice-focused. Participants learn:

• How to update, manage and configure Linux systems using the three major Linux distributions Red Hat, SUSE and Debian/Ubuntu; 
• Which tools and concepts must be mastered in order to efficiently create and manage an enterprise-level Linux infrastructure; and
• How the latest system administration methods can be used in practice.

This Training prepares participants to pass the LFCS test.
