1. Get started with Red Hat Enterprise Linux
Describe and define open source, Linux distributions, and Red Hat Enterprise Linux. Log into a Linux system and run simple commands using the shell. Create, manage, and delete local users and groups, as well as administer local password policies.
2. Manage networking and remote login
Configure network interfaces and settings on Red Hat Enterprise Linux servers. Configure secure command line service on remote systems, using OpenSSH.
3. Manage file permissions and SELinux security
Access, inspect, and use existing file systems on storage attached to a Linux server. Interpret and set access control lists (ACLs) on files to handle situations requiring complex user and group access permissions. Protect and manage the security of a server by using SELinux. Control network connections to services using the system firewall and SELinux rules.
4. Monitor and manage Linux
Evaluate and control processes running on a Red Hat Enterprise Linux system. Control and monitor network services and system daemons using systemd. Download, install, update, and manage software packages from Red Hat and yum package repositories. Schedule commands to run in the future, either one time or on a repeating schedule.
5. Analyse and tune system performance
Investigate and resolve issues in the web-based management interface, getting support from Red Hat to help solve problems. Locate and accurately interpret logs of system events for troubleshooting purposes. Run commands more efficiently by using advanced features of the bash shell, shell scripts, and various utilities provided by Red Hat Enterprise Linux. Improve system performance by setting tuning parameters and adjusting scheduling priority of processes. Manage the boot process to control services offered and to troubleshoot and repair problems.
6. Manage partitions and network-attached storage
Create and manage storage devices, partitions, file systems, and swap spaces from the command line. Create and manage logical volumes containing file systems and swap spaces from the command line. Manage storage using the Stratis local storage management system and use VDO volumes to optimize storage space in use. Use the NFS protocol to administer network-attached storage.
