 RECOMMENDED: FOR ANY KIND OF "COLLEAGUES"  
 ###RedHat Objectives###  
 ----------------------------------------------------------  
 . Boot, reboot, and shutdown the system normally  
 . Diagnose and correct problems at boot  
 . Boot systems into different runlevels for troubleshooting and system maintenance  
 . Use single-user mode to gain access to a system for which the root password is not known  
 . Diagnose and correct misconfigured networking settings  
 . Diagnose and correct hostname resolution problems  
 . Diagnose and address permissions problems and SELinux policy violations  
 . Diagnose and correct non-hardware disk storage problems  
 . Adding new partitions, logical volumes, filesystems, and swap areas to a system non-  
 destructively  
 . Manually open, mount, unmount, and close LUKS-encrypted filesystems  
 . Extend existing unencrypted ext4-formatted logical volumes  
 . Login or switch user to the root account  
 . Use ssh and VNC to access remote systems  
 . Locate and read on-line documentation using man, info, and files in /usr/share/doc  
 . Locate and analyze system log files  
 . Understand how to use grep and regular expressions to analyze text output  
 . Access a bash shell prompt and issue commands with correct syntax; use pipelines and I/O  
 redirection  
 . Use text editors such as gedit and vim to create and edit text files  
 . Manage system resources: identify CPU/memory intensive processes, adjust process priority  
 with renice, kill processes  
 . Manage files and directories: create/delete/copy/move; create hard and soft links  
 . Use tar, gzip, and bzip2 to archive and compress files  
 . Install Red Hat Enterprise Linux manually with the graphical installer from network installation  
 media  
 . Install Red Hat Enterprise Linux automatically using Kickstart  
 . Configure a physical machine as a RHEL-based virtualization host  
 . Manage virtual machines: install/start/stop/configure to start at boot/access a VM ́s graphical  
 console  
 . Manage disk partitions: understand MBR-style partitions (primary,extended,logical);  
 list/create/delete partitions  
 . Manage logical volumes: create/remove physical volumes, assign PVs to volume groups,  
 create/delete logical volumes  
 . Create and configure LUKS-encrypted partitions and logical volumes to prompt for password and  
 mount decrypted filesystem at boot  
 . Canage ext4 filesystems: create, label, mount, mount automatically at boot (by UUID or label),  
 unmount  
 . Mount and unmount CIFS and NFS network filesystems, manually or by configuring autofs  
 . Manage network devices: understand basic IP networking/routing, configure IP  
 addresses/default route statically or dynamically  
 . Manage name resolution: set local hostname, configure /etc/hosts, configure to use existing  
 DNS server  
 . Manage network services: check status, start, stop, configure to start automatically at boot  
 . Configure the scheduling of tasks using cron and at  
 . Manage local user and group accounts: create, delete, change passwords, adjust password  
 aging, adjust group memberships  
 . Use network user and group accounts stored on an existing LDAP directory service  
 . Manage standard permissions: list, interpret, change ugo/rwx  
 . Use sgid directories for collaboration  
 . Set and manage Access Control Lists (ACLs)  
 . Manage SELinux security: set enforcing/permissive modes, list file and process context, restore  
 default file context, use "booleans" to adjust policy  
 . Manage default firewall settings with basic tools  
 . Install and update software packages from RHN or remote repository, or from the local  
 filesystem  
 . Update the kernel package appropriately to ensure a bootable system  
 . Modify the system bootloader  
 . Configure the system to synchronize system time using remote NTP servers  
 . Deploy a VNC server that allows multiple desktops to be shared  
 . Deploy file sharing services with HTTP/FTP
