10. Verify from : cat /etc/group
There are two types of group, I) primary group II) Secondary or supplementary group.
I) Primary Group: Primary group defines the files/directories and process owner group there can be only one primary group of one user.
II) Secondary Group is used for permission. Where permission are defined for group members, user can access by belonging to that group.
Here user1, user2 and user3 belong as supplementary to training group. So these users get the permission of group member.
Q4. CORRECT TEXT
Create the group named sysadmin.
Answer and Explanation:
1. groupadd sysadmin
groupadd command is used to create the group and all group information is stored in /etc/group file.

Q7. CORRECT TEXT
Create a RAID Device /dev/md0 by creating equal two disks from available free space on your harddisk and mount it on /data.
Answer and Explanation:
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 buttonType the Mount PointSelect File system typeSelect
RAID LevelSelect Partitions/disks as a member of RAID.Click on ok
After Installation: We can create the RAID Device after Installation on command-line.
1. Create the Two partitions having equal size. (Specify the Size using Cylinder, find the remaining cylinder and divide by 2).
2. Change the Partition ID to fd (Linux raid Autodetect) by typing t.
3. Type w à To write on partitions table.
4. Use partprobe command to synchronic the partition table.
5. Use: mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/hda? /dev/hda?
6. Verify the RAID: mdadm --detail /dev/md0
7. mkfs -t ext3 /dev/md0
8. mount /dev/md0 /data
9. vi /etc/fstab
/dev/md0 /data ext3 defaults 0 0
10. Verify mounting devices using mount command.
Q8. CORRECT TEXT
There is a HTTP server 192.168.0.254 and all required packages are dumped in /var/www/html/rhel5 of that server. Install the Redhat Enterprise Linux 5 by creating following partitions:
/ 1000
/boot 200
/home 1000
/var 1000
/usr 4000
swap 2X256 (RAM SIZE)
Answer and Explanation:
Note: Examiner will provide you the Installation startup CD. And here mentioned size may vary see on the exam paper.
1. Insert the CD on CD-ROM and start the system.
2. In Boot: Prompt type linux askmethod
3. It will display the Language, keyboard selection.
4. It will ask you for the installation method.
5. Select the HTTP from the list
6. 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.
7. It will ask for the Web site name and Redhat Enterprise Linux Directory.
Specify the HTTP Server: 192.168.0.254
Directory: rhel5 à Because Default Directory for http is /var/www/html
8. After Connecting to the HTTP Server Installation start. Go upto the partition screen by selecting the different Options.
9. Create the partition According to the Question because Size and what-what partition should you create at installation time is specified in your question
10. Then select the MBR Options, time zone and go upto package selections.
It is another Most Important Time of installation. Due to the time limit, you should be care about the installation packages. At Exam time you these packages are enough.
X-Window System
GNOME Desktop
(these two packages are generally not required)
Administration Tools.
System Tools
Windows File Server

Q9. CORRECT TEXT
You have a domain in your LAN named example.com and my133t.org. Allow the
- Allow the FTP connection only from local domain.
- Deny the FTP connection from my133t.org
Answer and Explanation:
1. vi /etc/hosts.deny
vsftpd:ALL EXCEPT .example.com
or
1. vi /etc/hosts.deny
vsftpd:ALL
2. vi /etc/hosts.allow
vsftpd:.example.com
We can secure the services using tcp_wrappers. There are main two files, /etc/hosts.allow and /etc/hosts.deny.
There will be three stage access checking
- Is access explicitly permitted? Means permitted from /etc/hosts.allow?
- Otherwise, Is access explicitly denied? Means denied from /etc/hosts.deny?
- Otherwise, by default permit access if neither condition matched.
To deny the services we can configure /etc/hosts.deny file using ALL and EXCEPT operation.
Pattern of /etc/hosts.allow and /etc/hosts.deny file is:
Demon_list:client_list:options
In Client list can be either domain name or IP address.
Q10. CORRECT TEXT
