This course covers the same topics as the Red Hat System Administration II (RH135) course.
The course focuses on the key tasks needed to become a full time Linux administrator. It goes deep into enterprise Linux administration including file systems and partitioning, logical volumes, SELinux, firewalling and troubleshooting. Attending both Red Hat System Administration I and Red Hat System Administration II can help in the preparation for the Red Hat Certified System Administrator (RHCSA) exam. This performance based exam (EX200) tests the users knowledge and skill in areas of system administration common across a wide range of environments and deployment scenarios.
