Ya the yum installer & rpm are used but yesterday my mistake as thet told to use yum , but i used RPM for installing kernel so 5 marks reduced
RHCT- technician level which installing and system maintanence
RHCE - Engineering level which u used be able to deal with server and client -- package of servers
Exam time is 5 & half hours , morethan enough
bash is used when : fstab entries are modified and no rescue cd is need directly entering in to bash we can solve
no graphical is allowed ,, graphics should not be installed - but configuring NTP and cups we graphics that is on the RHCT part , RHCE fully command
no , application skills are needed -- i told u client / server part is full for RHCE
RHCE & RHCT are same both exam @ once includes 5 & 1/2 hrs , but there 2 & 1/2 hrs eligibility that if u pass then u r allowed to write the RHCT or RHCE there r 8 question there 4 goes for RHCT , another 4 goes for RHCE RHCE includes trouble shooting , the compulsary part is first 4 on RHCT if one goes wrong thats all no certificate
one month is enough , if u already worked on like linux servers not desktop , linux destop is varied frm linux servers , so practice with server and client
