Phase 1 – 8 Questions
Q1. Login Problem (Compulsory)
Q2. Configure network settings to specification so that you can ping 192.168.1.254 (Compulsory)
Q3. dig server1.example.com 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
