Dig Server1.example.com, Resolve to successfully through DNS Where DNS server is 172.24.254.254

A. #vi /etc/resolv.conf nameserver 172.24.254.254 # dig server1.example.com #host server1.example.com DNS is the Domain Name System, which maintains a database that can help your computer translate domain names such as www.redhat.com to IP addresses such as
216.148.218.197. As no individual DNS server is large enough to keep a database for the entire Internet, they can refer requests to other DNS servers. B. #vi /etc/resolv.conf nameserver 172.24.254.254 # dig server1.example.com #host server1.example.com DNS is the Domain Name System, which maintains a database that can help your computer translate domain names such as www.redhat.com to IP addresses such as
216.148.218.197. As no individual DNS server is large enough to keep a database for the entire Internet, they can refer requests to other DNS servers. DNS is based on the named daemon, which is built on the BIND (Berkeley Internet Name Domain) package developed through the Internet Software Consortium Users wants to access by name so DNS will interpret the name into ip address. You need to specify the Address if DNS server in each and every client machine. In Redhat Enterprise Linux, you need to specify the DNS server into /etc/resolv.conf file. After Specifying the DNS server address, you can verify using host, dig and nslookup commands.

There is a HTTP server 192.168.0.254 and all required packages are dumped in /var/www/html/rhel4 of that server. Install the Redhat Enterprise Linux 4 by creating following partitions: / 1000 /boot 200 /home 1000 /var 1000 /usr 4000 swap 2X256 (RAM SIZE)

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 HTTP 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 Web site name and Redhat Enterprise Linux Directory. Specify the HTTP Server: 192.168.0.254 Directory: rhel4 Because Default Directory for http is /var/www/html
After Connecting to the HTTP Server Installation start. Go upto the partition screen by selecting the different Options. B. Examiner will provide you the Installation startup CD . And here mentioned size may vary see on the exam paper.

QUESTION NO: 4
neo user tried by: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70 files created successfully. Again neo tried to create file having 70K using following command: dd if=/dev/zero of=/home/neo/somefile bs=1024 count=70 But he is unable to create the file. Make the user can create the file less then 70K.

A. Very Tricky question from redhat. Actually question is giving scenario to you to implement quota to neo user. You should apply the quota to neo user on /home that neo user shouldn't occupied space more than 70K.
1. vi /etc/fstab
LABEL=/home /home ext4 defaults,usrquota 0 0 -> To enable the quota on filesystem you should mount the filesystem with usrquota for user quota and grpquota for group quota.
touch /home/aquota.user-> Creating blank quota database file.
mount -o remount /home ->Remounting the /home with updated mount options. You can verify that /home is mounted with usrquota options or not using mount command.
quotacheck -u /home ->Initialization the quota on /home
edquota -u neo /home-> Quota Policy editor
See the snapshot 1 Disk quotas for user neo (uid 500): 2 Filesystem blocks soft hard inodes soft hard
4 /dev/mapper/vo-myvol 2 31 75 1 1 1 Can you set the hard limit 70 and soft limit as you think like 50. Verify using the repquota /home command. B. Very Tricky question from redhat.

QUESTION NO: 5
There are more then 400 Computers in your Office. You are appointed as a System Administrator. But you don't have Router. So, you are going to use your One Linux Server as a Router. How will you enable IP packets forward?

A. /proc is the virtual filesystem, we use /proc to modify the kernel parameters at running time. # echo "1" >/proc/sys/net/ipv4/ip_forward
To enable the IP forwarding on next reboot also you need to set the parameter. net.ipv4.ip_forward=1 Here 0 means disable, 1 means enable. B. /proc is the virtual filesystem, we use /proc to modify the kernel parameters at running time. # echo "1" >/proc/sys/net/ipv4/ip_forward
/etc/sysctl.conf when System Reboot on next time, /etc/rc.d/rc.sysinit scripts reads the file /etc/sysctl.conf. To enable the IP forwarding on next reboot also you need to set the parameter. net.ipv4.ip_forward=1 Here 0 means disable, 1 means enable. C. /proc is the virtual filesystem, we use /proc to modify the kernel parameters at running time. # echo "1" >/proc/sys/net/ipv4/ip_forward
/etc/sysctl.conf when System Reboot on next time, /etc/rc.d/rc.sysinit scripts reads the file /etc/sysctl.conf.
