Practice Free EX200 Red Hat Certified System Administrator - RHCSARHEL 10 Exam Questions Answers With 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.

Solution:

dnf install -y autofs

mkdir -p /automount

echo "/automount /etc/auto.automount --timeout=30" > > /etc/auto.master

echo "public -ro,sync nfs.lab.example.com:/public" > > /etc/auto.automount

echo "private -rw,sync nfs.lab.example.com:/private" > > /etc/auto.automount

systemctl enable --now autofs

Detailed Explanation:

/etc/auto.master defines the main AutoFS map.

/etc/auto.automount defines the indirect map entries.

public will mount read-only.

private will mount read-write.

AutoFS mounts on access rather than permanently at boot.

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:

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:

mkdir -p /share/projects

chown alex /share/projects/

chmod a+rwx,+t /share/projects/

ls -ld /share/projects/

Detailed Explanation:

chmod a+rwx gives read, write, and execute to everyone.

+t sets the sticky bit.

Sticky bit on a shared directory means users can create files, but only the file owner, directory owner, or root can delete them.

This is the same model used on /tmp.

Solution:

lvextend -L +500M /dev/vgdata/lvbackup

xfs_growfs /backup

df -h /backup

Detailed Explanation:

lvextend increases the LV size.

xfs_growfs expands the XFS filesystem while mounted.

This is a classic RHCSA storage task and aligns with RHEL 10 LVM/XFS workflows. ( Red Hat Documentation )

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.
