Explanation:
Solution:
Create timer unit:
cat > /etc/systemd/system/backup-now.timer < < 'EOF'
[Unit]
Description=Daily backup timer
[Timer]
OnCalendar=*-*-* 02:00:00
Persistent=true
[Install]
WantedBy=timers.target
EOF
Enable it:
systemctl daemon-reload
systemctl enable --now backup-now.timer
systemctl list-timers --all | grep backup-now
Detailed Explanation:
* OnCalendar=*-*-* 02:00:00 means daily at 02:00.
* Persistent=true runs missed jobs after boot if the system was off.
* timers.target is the normal target for timer units.
* RHEL 10 documentation includes systemd timer units as a standard scheduling mechanism. ( Red Hat
Documentation )

Explanation:
Solution:
dnf install -y autofs
mkdir -p /shares
echo "/shares /etc/auto.shares" > > /etc/auto.master
echo "projects -fstype=nfs,rw server1:/srv/nfs/projects" > /etc/auto.shares
systemctl enable --now autofs
ls /shares/projects
Detailed Explanation:
* /etc/auto.master defines the main map.
* /etc/auto.shares defines the indirect mount entry.
* The mount happens on demand when /shares/projects is accessed.
* RHEL 10 file-system documentation includes AutoFS for on-demand mounts. ( Red Hat
Documentation )

Explanation:
Solution:
dd if=/dev/zero of=/swapfile bs=1M count=512
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
echo "/swapfile swap swap defaults 0 0" > > /etc/fstab
swapon --show
Detailed Explanation:
* dd creates the file.
* chmod 600 protects swap contents.
* mkswap prepares the file as swap.
* swapon activates it now.
* /etc/fstab ensures it is enabled at boot.

Explanation:
Solution:
stratis filesystem snapshot pool1 fs1 fs1-snap
stratis filesystem list
Detailed Explanation:
* This creates a snapshot of the existing Stratis file system.
* Snapshots are useful for rollback, backup, and testing operations.
* Stratis features, including pool and file-system management, are part of RHEL 10 file-system
administration. ( Red Hat Documentation )

See the solution below in Explanation.
Explanation:
Solution:
* Create the destination directory if needed:
mkdir -p /root/tomfiles
* Find and copy:
find / -type f -user tom -exec cp -pvf {} /root/tomfiles/ \;
Detailed Explanation:
* find / searches the whole filesystem.
* -type f restricts results to files.
* -user tom matches owner tom.
* -exec cp -pvf copies each file with verbose and force options.
* mkdir -p is added as a safe preparation step.
