Sample Question: Part-01

Morning Session – 2 and half hours(Tshooting and Maintenance)

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

Trouble shooting and Maintenance(Phase 1: 8 Questions)

Q1. Login Problem (Compulsory)

Trouble shooting and Maintenance(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
