A system administrator wanna be, need an advice about using ArchLinux

view story

https://bbs.archlinux.org – Hello, i'm studying the RHCSA certification track, I have a prior  experience in Linux, i really love Arch. But i feel that it's quite different from Fedora and RHEL. For example, when i want to configure the network in Fedora, I go to /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-XXX. But in Arch i find it using netcl which changes a lot of stuff i guess.So i need an advice, would it be stumbling for me to use Arch and study for RHCSA in virtual machine or something ? Does getting used to Arch different configuration methods takes a lot of effort that can driv (HowTos)
