Explanation
* use the authconfig --nisserver=<NIS SERVER> --nisdomain=<NIS DOMAIN> -- update Example: authconfig --niserver=192.168.0.254 --nisdomain=RHCE --update or system-config-authentication
* Click on Enable 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 with option or system-config authentication 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.

Solution:
# Check the disk layout
[root@node2 ~]# lsblk
# Partition the disk
[root@node2 ~]# fdisk /dev/vdb
Welcome to fdisk (util-linux 2.37.4).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): n # Add a new partition
Partition type
p primary (1 primary, 0 extended, 3 free) # Primary partition
e extended (container for logical partitions) # Extended partition
Select (default p): p
Partition number (2-4, default 2): # Press Enter
First sector (1026048-20971519, default 1026048): # Press Enter
***Note: The partition size must be larger than the total size, it should not be exactly equal to. It is recommended to add an extra 200M.
Last sector, +/-sectors or +/-size{K,M,G,T,P} (1026048-20971519, default 20971519): +1200M # Partition size
Created a new partition 2 of type 'Linux' and of size 512 MiB.
Command (m for help): w # Save and exit
The partition table has been altered.
Syncing disks.
# Create volume group and logical volume
[root@node2 ~]# vgcreate -s 16M myvg /dev/vdb4
[root@node2 ~]# lvcreate -l 50 -n mylv myvg
# Install vfat support
[root@node2 ~]# yum provides */mkfs.vfat
[root@node2 ~]# yum -y install dosfstools
# Format the logical volume with vfat filesystem
[root@node2 ~]# mkfs.vfat /dev/myvg/mylv
# Create mount point
[root@node2 ~]# mkdir /mnt/mydata
# Update /etc/fstab for automatic mounting
[root@node2 ~]# vim /etc/fstab
/dev/myvg/mylv /mnt/mydata vfat defaults 0 0
# Mount the logical volume
[root@node2 ~]# mount -a

Explanation:
Solution:
mkdir -p /webdata
semanage fcontext -a -t httpd_sys_content_t "/webdata(/.*)?"
restorecon -Rv /webdata
ls -Zd /webdata
Detailed Explanation:
* semanage fcontext defines a persistent SELinux file-context rule.
* restorecon applies the correct labels to the directory and contents.
* httpd_sys_content_t is the standard read-only content type for Apache.
* RHEL 10 SELinux documentation covers persistent labeling with semanage and applying labels with
restorecon. ( Red Hat Documentation )

Explanation:
Solution:
lvcreate -L 1G -n lvbackup vgdata
mkfs.xfs /dev/vgdata/lvbackup
mkdir -p /backup
echo "/dev/vgdata/lvbackup /backup xfs defaults 0 0" > > /etc/fstab
mount -a
df -h /backup
Detailed Explanation:
* lvcreate allocates a new LV from the existing VG.
* mkfs.xfs creates the filesystem.
* /etc/fstab makes the mount persistent across reboot.
* mount -a tests the fstab entry immediately.
* RHEL 10 storage documentation continues to use LVM and XFS as core administration topics. ( Red
Hat Documentation )

see explanation below.
Explanation
* Use netconfig command
* Enter the IP Address as given station number by your examiner: example: 172.24.0.1
* Enter Subnet Mask
* Enter Default Gateway and primary name server
* press on ok
* ifdown eth0
* ifup eth0
* verify using ifconfig
In the lab server is playing the role of router, IP forwarding is enabled. Just set the Correct IP and gateway, you can ping to 172.25.254.254.
