Some question relate to RHCE
* In the RHCE the candidate needs to configure host-based and user-based security for the services
what is the different host-based and user-based security?
* The candidate all needs to " use /proc/sys and sysctl to modify and set kernel run-time parameters"
It is not better to edit sysctl.conf and forget about echo 1 > /proc because this will only change the setting for that session, and after the machine reboot, the change will be reset.
* Also, you need to install and update packages using rpm and to configure the system to update/install packages from remote repositories using yum or pup.
If you can use YUM why then install and update packages using rpm.
THANKS
