Red Hat Linux System Administration (RHCSA) in 21 Days

Red Hat Systems Administrators, who work on Linux operating systems, configure, implement, and deploy systems and take care of security issues, besides managing system backups and adding and removing users. They will be part of a team that handles daily tickets and devises and implements technology solutions.

They need to be good team players with excellent communication skills. Red Hat Systems Administrators also need to have an analytical bent of mind and competent problem-solving skills.
