Solution:
Using the browser open the URL in the question, download kernel file to root or home directory. uname –r// check the current kernel version
rpm –ivh kernel-*.rpm
vi /boot/grub.conf// check
Some questions are: Install and upgrade the kernel as required. To ensure that grub2 is the default item for startup.
Yum repo : http://content.example.com/rhel7.0/x86-64/errata
OR
uname -r // check kernel
Yum-config-manager

Question 5
The system ldap.example.com provides an LDAP authentication service. Your system should bind to this service as follows:
The base DN for the authentication service is dc=domain11, dc=example, dc=com LDAP is used to provide both account information and authentication information. The connection should be encrypted using the certificate at http://host.domain11.example.com/pub/domain11.crt
When properly configured, ldapuserX should be able to log into your system, but will not have a home directory until you have completed the autofs requirement. Username: ldapuser11
Password: password
Solution:
system-config-authentication LDAP user DN=dc=domain11,dc=example,dc=com Server= host.domain11.example.com
Certificate=

Question 6
Create a logical volume
Create a new logical volume as required:
Name the logical volume as database, belongs to datastore of the volume group, size is 50 PE. Expansion size of each volume in volume group datastore is 16MB.
Use ext3 to format this new logical volume, this logical volume should automatically mount to /mnt/database
Solution:
fdisk -cu /dev/vda// Create a 1G partition, modified when needed
partx –a /dev/vda
pvcreate /dev/vdax
vgcreate datastore /dev/vdax –s 16M
lvcreate– l 50 –n database datastore

Question 7
/data Directory is shared from the server1.example.com server. Mount the shared directory that:
Solution:
1. vi /etc/auto.master
/mnt /etc /auto.misc --timeout=50
vi /etc/auto.misc
data -rw,soft,intr server1.example.com:/data
service autofs restart
chkconfig autofs on
When you mount the other filesystem, you should unmount the mounted filesystem, Automount feature of linux helps to mount at access time and after certain seconds, when user unaccess the mounted directory, automatically unmount the filesystem.
/etc/auto.master is the master configuration file for autofs service. When you start the service, it reads the mount point as defined in /etc/auto.master.

Question 8
Your System is going to use as a Router for two networks. One Network is 192.168.0.0/24 and Another Network is 192.168.1.0/24. Both network's IP address has assigned. How will you forward the packets from
one network to another network?
Solution:
echo "1" >/proc/sys/net/ipv4/ip_forward
vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
If you want to use the Linux System as a Router to make communication between different networks, you need enable the IP forwarding. To enable on running session just set value 1 to
/proc/sys/net/ipv4/ip_forward. As well as automatically turn on the IP forwarding features on next boot set on /etc/sysctl.conf file.

Question 22
According the following requirements, configure autofs service and automatically mount to user's home directory in the ldap domain.
- Instructor.example.com (192.168.0.254) has shared /home/guests/ldapuserX home directory to your system by over NFS export, X is your hostname number.
- LdapuserX's home directory is exist in the instructor.example.com: /home/ guests/ldapuserX
- LdapuserX’s home directory must be able to automatically mount to /home/ guests/ldapuserX in your system.
- Home directory have write permissions for the corresponding user.
However, you can log on to the ldapuser1 - ldapuser99 users after verification. But you can only get your corresponding ldapuser users. If your system's hostname is server1.example.com, you can only get ldapuser1's home directory.
Solution:
(1)find /etc -size 10k -exec cp {} /tmp/findfiles \;
(2)find / -user lucy -exec cp -a {} /tmp/findfiles \;
Note: If find users and permissions, you need to use cp - a options, to keep file permissions and user attributes etc.
