CompleteNetworkingNotes.com try its level best to keep it up to date but still we suggest you to check Redhat's official site for update before appearing in test. Study Points for the RHCE Exam use standard command line tools (e.g., ls, cp, mv, rm, tail, cat, etc.) to create, remove, view, and investigate files and directories use grep, sed, and awk to process text streams and files use a terminal-based text editor, such as vim or nano, to modify text files use input/output redirection understand basic principles of TCP/IP networking, including IP addresses, netmasks, and gateways for IPv4 and IPv6 use su to switch user accounts use passwd to set passwords use tar, gzip, and bzip2 configure an email client on Red Hat Enterprise Linux use text and/or graphical browser to access HTTP/HTTPS URLs use lftp to access FTP URLs RHCT skills Troubleshooting and System Maintenance RHCTs should be able to: boot systems into different run levels for troubleshooting and system maintenance diagnose and correct misconfigured networking diagnose and correct hostname resolution problems configure the X Window System and a desktop environment add new partitions, filesystems, and swap to existing systems use standard command-line tools to analyze problems and configure system Installation and Configuration RHCTs must be able to: perform network OS installation implement a custom partitioning scheme configure printing configure the scheduling of tasks using cron and at attach system to a network directory service, such as NIS or LDAP configure autofs add and manage users, groups, quotas, and File Access Control Lists configure filesystem permissions for collaboration install and update packages using rpm properly update the kernel package configure the system to update/install packages from remote repositories using yum or pup modify the system bootloader implement software RAID at install-time and run-time use /proc/sys and sysctl to modify and set kernel run-time parameters use scripting to automate system maintenance tasks configure NTP for time synchronization with a higher-stratum server RHCE skills Troubleshooting and System Maintenance RHCEs must demonstrate the RHCT skills listed above, and should be able to: use the rescue environment provided by first installation CD diagnose and correct boot failures arising from bootloader, module, and filesystem errors diagnose and correct problems with network services (see Installation and Configuration below for a list of these services) add, remove, and resize logical volumes diagnose and correct networking services problems where SELinux contexts are interfering with proper operation. Installation and Configuration RHCEs must demonstrate the RHCT-level skills listed above, and they must be capable of configuring the following network services: HTTP/HTTPS SMB NFS FTP Web proxy SMTP IMAP, IMAPS, and POP3 SSH DNS (caching name server, slave name server) NTP For each of these services, RHCEs must be able to: install the packages needed to provide the service configure SELinux to support the service configure the service to start when the system is booted configure the service for basic operation Configure host-based and user-based security for the service RHCEs must also be able to: configure hands-free installation using Kickstart implement logical volumes at install-time use iptables to implement packet filtering and/or NAT use PAM to implement user-level restrictions Based on this RHCE guide we have created step by step guide of RHCE exam. By our RHCE guide you can get your RHCE certificates. We have managed various practical example and suggest you to go through all these.
