This course is designed to provide students with the necessary skills and abilities to work as a professional Linux system administrator.
The course covers how to administer, configure and upgrade Linux systems running one of the three major Linux distribution families: Red Hat, SUSE, Debian/Ubuntu, how to master the tools and concepts you’ll need to efficiently build and manage an enterprise Linux infrastructure. It also covers how to use state-of-the-art system administration techniques in real-life scenarios via practical labs.
This course prepares the candidate for the Linux Foundation Certified System Administrator (LFCS) exam, which is also a required component of the MCSA: Linux on Azure Certification.
