A. Very Easy QUESTION, nameserver is specified in QUESTION,
vi /etc/resolv.conf nameserver 192.168.0.254
host server1.example.com

B. Very Easy QUESTION, nameserver is specified in QUESTION,
vi /etc/resolv.conf nameserver 192.167.0.253
host server1.example.com

A. use the authconfig or system-config-authentication
Select the [*] USE NIS
Type the NIS Domain: RHCE
Type Server 192.168.0.254 then click on next and ok
You will get a ok message.
Create a Directory /rhome/stationx where x is your station number.
vi /etc/auto.master and write at the end of file /rhome/stationx /etc/auto.home --timeout=60
vi /etc/auto.home and write * -rw,soft,intr 192.168.0.254:/rhome/stationx/& Note: please specify your station number in the place of x.
Service autofs restart
Login as the nisuser2001 or nisuser2002 on another terminal will be Success. According to QUESTION, RHCE domain is already configured. We have to make a client of RHCE domain and automatically mount the home directory on your system. To make a member of domain, we use the authconfig or system-configauthentication command. There a are lots of authentication server i.e NIS, LDAB, SMB etc. NIS is a RPC related Services, no need to configure the DNS, we should specify the NIS server address. Here Automount feature is available. When user tried to login, home directory will automatically mount. The automount service used the /etc/auto.master file. On /etc/auto.master file we specified the mount point the configuration file for mount point.

A. Examiner will provide you the Installation startup CD . And here mentioned size may vary see on the exam paper.
Insert the CD on CD-ROM and start the system.
In Boot: Prompt type linux askmethod
It will display the language, keyboard selection.
It will ask you for the installation method.
Select the NFS Image from the list
It will ask the IP Address, Net mask, Gateway and Name Server. Select Use Dynamic IP Configuration: because DHCP Server will be configured in your exam lab.
It will ask for the NFS Server Name and Redhat Enterprise Linux Directory. Specify the NFS Server: 192.168.0.254 Directory: /var/ftp/pub
After Connecting to the NFS Server Installation start in GUI. Go up to the partition screen by selecting the different Options.
Create the partition According to the QUESTION because Size and what-what partition should you create at installation time is specified in your QUESTION.

A. Redhat Enterprise Linux 5 Supports the RAID LEVEL 0, RAID LEVEL 1, RAID LEVEL 5 and RAID LEVEL 6 at installation time. You can create it at installation time later no need to type lots of commands for RAID . At Installation Time:
Create the partitions using diskdruid.
Create the Partitions having File system Type Software RAID .
Click on RAID button
Type the Mount Point
Select File system type
Select RAID Level
Select Partitions/disks as a member of RAID .
8. Click on ok After Installation: We can create the RAID Device after Installation on command-line.
Create the Two partitions having equal size. (Specify the Size using Cylinder, find the remaining cylinder and divide by 2).
Change the Partition ID to fd (Linux raid Autodetect) by typing t.
Type w To write on partitions table.
Use partprobe command to synchronic the partition table.
Use: mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda?
/dev/hda?
Verify the RAID: mdadm --detail /dev/md0
mkfs -t ext3 /dev/md0
mount /dev/md0 /data
vi /etc/fstab
/dev/md0 /data ext3 defaults 0 0
Verify mounting devices using mount command.

A. First check the size of Logical Volume: lvdisplay /dev/vo/myvol
Increase the Size of Logical Volume: lvextend -L+124M /dev/vo/myvol
Make Available the size on online: ext4online /dev/vo/myvol
Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol
Verify that the size comes in online or not: df -h We can extend the size of logical Volume using the lvextend command. As well as to decrease the size of Logical Volume, use the lvresize command. In LVM v3 we can extend the size of Logical Volume without unmount as well as we can bring the actual size of Logical Volume on online using ext2online command.

B. First check the size of Logical Volume: lvdisplay /dev/vo/myvol
Increase the Size of Logical Volume: lvextend -L+121M /dev/vo/myvol
Make Available the size on online: ext2online /dev/vo/myvol
Verify the Size of Logical Volume: lvdisplay /dev/vo/myvol
Verify that the size comes in online or not: df -h We can extend the size of logical Volume using the lvextend command. As well as to decrease the size of Logical Volume, use the lvresize command.
