Free Practice Questions for the RedHat RHCSA EX200 Exam (2026 Updated)

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 )

Solution:

groupadd admin

mkdir -p /common/admin

chgrp admin /common/admin

chmod 2770 /common/admin

Detailed Explanation:

groupadd admin creates the group.

chgrp admin assigns the group ownership.

2770 means:

2 = SGID

7 = owner rwx

7 = group rwx

0 = others no access

This is a standard shared group-admin directory design.

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.

Solution:

mkdir -p /backup

tar -cvf /root/logs.tar /var/log

tar -xvf /root/logs.tar -C /backup

Detailed Explanation:

tar -cvf creates an uncompressed archive.

tar -xvf extracts the archive.

-C /backup tells tar where to extract the files.

This is a common RHCSA-style archive and restore task.

Solution:

Reboot the server.

At the GRUB menu, highlight the kernel entry and press e.

Find the line starting with linux.

Append:

systemd.unit=emergency.target

Press Ctrl+x to boot.

Detailed Explanation:

This changes the boot target only for the current boot.

Emergency mode is useful for rescue and maintenance tasks.

Red Hat’s RHEL 10 systemd guidance documents booting with systemd.unit= < name > .target from GRUB. ( Red Hat Documentation )

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.

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 )

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 )

Solution:

Open the firewall port and HTTP service:

firewall-cmd --permanent --add-port=82/tcp

firewall-cmd --permanent --add-service=http

firewall-cmd --reload

Add SELinux port labeling:

semanage port -a -t http_port_t -p tcp 82

Detailed Explanation:

firewall-cmd --permanent makes the change persistent.

--add-port=82/tcp opens the custom TCP port.

--add-service=http keeps standard HTTP allowed too.

SELinux blocks services on unexpected ports unless the port is labeled correctly.

http_port_t tells SELinux that port 82 is valid for web services.
