RHCE Sample Question

Morning Session – 2 and half hours

Phase 1 – 8 Questions

Q1. Login Problem (Compulsory)

Q2. Configure network settings to specification so that you can ping (Compulsory)

Q3. dig should work properly (Compulsory)

Q4. Successfully login to init 5 as root (Compulsory)

Q5. Resize a 200 MB LVM to a 100 MB LVM without losing data

Q6. User neo should be able to create 30K file but not 70K file (quotas)

Q7. Create 100 MB partition and mount it as /mnt/new. Should work across reboot (Compulsory)

Q8. Showmount –e should show the /export directory as available.

Phase 2 – Boot Troubleshooting

Examiner will insert a CD which will perform a very basic installation in text mode. The examiner will then remove the CD and then ask you to reboot. Once you reboot, you will get a kernel panic error. Once you set this right, your system will not boot because it cannot see the LABEL root. You will need to use resuce mode, find the device that has the /etc/fstab file and then modify it in such a way that fstab contains the line LABEL=/ instead of LABEL=root

If the system boots without any problems into runlevel 3, then 20 marks.
If the system boots into maintenance mode, then 10 marks
If the system does not boot at all, then 0 marks

Sample Model Question

Two Parts:-
Trouble Shooting and Maintenance – morning session – duration 2.5 hrs
RHCT and RHCE both combined – afternoon session - duration 3 hrs.
Trouble Shooting and Maintenance :- (Two Phases)
=>Phase One – 8 questions
=>Phase Two – 2 questions
Phase One:-
Login Problem –
Username: root
Password: redhat
The candidate should able to login with username and password as given above(COMPULSORY)
Your system should able to ping with the given IP (server)
NFS. showmount command should show the exported directory.
LVM (resizing the logical volume)
Quota (user limit given)
Creating and mounting a new partition (COMPULSORY)
DIG should execute properly, giving you the answer, authority and query section of a given IP (server).
Changing the run level to 5. User should able to login in GUI mode.
The Compulsory Questions should be completed in one hour of maximum. Failing to do this will disqualify the candidate from continuing the exam.
The candidate should report to the examiner as soon as he feels he had completed.
Examiner will give the confirmation that he had completed the compulsory question successfully. He can continue with the remaining questions.
Phase Two :-
The candidate can report to the examiner after completing the phase one questions. However he can not get the confirmation for the successful completion of remaining (except Compulsory) questions. The examiner will give you a CD which will put your system onto a small installation after typing phase two in the installation screen.
After the installation the candidate will be in grub screen asking for OS. When you enter into the OS, Kernel Panic error will occur. The following problems are the components of Phase Two.
Boot Problem (Arguments May be edited in /boot/grub/grub.conf).
fstab Problem ( /etc/fstab file may be edited).
After completing the Trouble Shooting and Maintenance Session the candidate can go for a break.
Note: one can not go back to Phase One after entering Phase Two.
Only for the Compulsory questions one can get confirmation.
Failing to score 80% will result in losing the certification, but one can go thro’ the other sections of the exam.
Enrolling your name and email id in the given address.
Installation of any rpm.
Installation of EL3 with given partion specification along with raid .
Group Administration.

Setting the given user to receive all mails which are directed to a group.
Configuring Mail Server.
Configuring Samba.
NFS (The candidate should export successfully the specified file/directory to the specified network )
