Correct Answer:

See the solution below in Explanation.
Explanation:
Solution:
dnf install -y vdo kmod-kvdo lvm2
pvcreate /dev/sdc
vgcreate vdo-volumegroup /dev/sdc
lvcreate --type vdo -n vdo-logicalvolume -L 5G -V 50G vdo-volumegroup/vdo-pool
mkfs.xfs /dev/vdo-volumegroup/vdo-logicalvolume
Detailed Explanation:
* VDO provides compression and deduplication.
* -L 5G sets the physical backing size.
* -V 50G sets the logical exposed size.
* This allows thin, optimized storage presentation.
* The exact commands are taken from the RHCSA dataset embedded in the uploaded lab HTML.

Correct Answer:

See the solution below in Explanation.
Explanation:
Solution:
dnf install -y httpd policycoreutils-python-utils
mkdir -p /webdata
echo "RHEL10 Web Server" > /webdata/index.html
sed -i 's/^Listen 80/Listen 8080/' /etc/httpd/conf/httpd.conf
semanage port -a -t http_port_t -p tcp 8080
firewall-cmd --permanent --add-port=8080/tcp
firewall-cmd --reload
systemctl enable --now httpd
systemctl restart httpd
ss -tulpn | grep 8080
Detailed Explanation:
* Apache defaults to port 80, so Listen 8080 changes the service port.
* SELinux must allow Apache to bind to 8080, which is done with semanage port.
* firewall-cmd opens the port externally.
* RHEL 10 documents firewalld as the standard firewall management interface and SELinux port
labeling for confined services. ( Red Hat Documentation )

Solution:
useradd harry
passwd harry
chage -M 30 -d 0 harry
chage -l harry
Detailed Explanation:
* useradd harry creates the local user.
* passwd harry sets the initial password.
* chage -M 30 sets the maximum password age to 30 days.
* chage -d 0 forces the user to change the password at next login.
* chage -l harry verifies the policy.

Correct Answer:

See the solution below in Explanation.
Explanation:
Solution:
* Create the swap partition:
fdisk /dev/sdb
partprobe /dev/sdb
* Format it for swap:
mkswap /dev/sdb2
* Enable it:
swapon /dev/sdb2
* Persist it in /etc/fstab:
echo "/dev/sdb2 swap swap defaults 0 0" > > /etc/fstab
* Verify:
swapon --show
Detailed Explanation:
* mkswap prepares the partition as swap space.
* swapon activates it immediately.
* Adding an /etc/fstab entry ensures it survives reboot.
* The lab uses a partition-based swap workflow.

Solution:
# Install and enable tuned
[root@node2 ~]# yum -y install tuned
[root@node2 ~]# systemctl enable tuned
[root@node2 ~]# systemctl restart tuned
# Check the recommended configuration scheme for the system
[root@node2 ~]# tuned-adm recommend
virtual-guest
# Switch to the specified configuration scheme
[root@node2 ~]# tuned-adm profile virtual-guest
