RHCSA and RHCE are Redhat/Centos specific, while LPIC are trying to cross-distribution, so the questions are more generic which can apply to different distribution.
(e.g. service vsftpd status vs /etc/init.d/vsftpd status)
The exam for RHCE/RHCSA are performance based, which give you a set of tasks which you need to perform during the exam. While LPIC is only MC based.
So for LPIC, you could possibly pass the exam without hands on doing something. But in RHCSA/RHCE, you need to at least hands on building some basic server like samba, NFS.
Furthermore, after studying RHCSA/RHCE, I found the documentation from Redhat are indeed very good. While there is not much guide or books related to LPIC exam, which makes the exam even more difficult with its broad scope. |
