Appendix B: Sample RHCSA Exam 2

Setup for Sample Exam 2:

• Build a virtual machine with RHEL 9 Server with GUI
• Use a 20GB disk for the OS with default partitioning.
• Add 1x400MB disk and a network interface.
• Do not configure the network interface or create a normal user account during installation.

Tasks:

Task 01: Using the nmcli command,

• Configure a network connection on the primary network device:
  • IP address 192.168.0.242/24,
  • gateway 192.168.0.1, and
  • nameserver 192.168.0.1.

Use different IP assignments based on your lab environment.

Task 02: Using the hostnamectl command,

• set the system hostname to rhcsa2.example.com and alias rhcsa2.
• Make sure that the new hostname is reflected in the command prompt.

Task 03: Create a user account called user70

• With UID 7000 and
• Comments “I am user70”.
• Set the maximum allowable inactivity for this user to 30 days.

Task 04: Create a user account called user50

• With a non-interactive shell.

Task 05: Attach the RHEL 9 ISO image to the VM and mount it persistently to /mnt/dvdrom.

• Define access to both repositories and confirm.

Task 06: Create a logical volume called lv1

• Size equal to 10 LEs in vg1 volume group (create vg1 with PE size 8MB in a partition on the 400MB disk).
• Initialize the logical volume with XFS type and mount it on /mnt/lvfs1.
• Create a file called lv1file1 in the mount point.
• Set the file system to automatically mount at each system reboot.

Task 07: Add a group called group20

• Change group membership on /mnt/lvfs1 to group20.
• Set read/write/execute permissions on /mnt/lvfs1 for the owner, group members, and others.

Task 08: Extend the file system in the logical volume lv1 by 64MB without unmounting it and without losing any data.

• Confirm the new size for the logical volume and the file system.

Task 09: Create a swap partition of size 85MB on the 400MB disk. Use its UUID and ensure it is activated after every system reboot.

Task 10: Create a disk partition of size 100MB on the 400MB disk

• Format it with Ext4 file system structures.
• Assign label stdlabel to the file system.
• Mount the file system on /mnt/stdfs1 persistently using the label.
• Create file stdfile1 in the mount point.

Task 11: Use the tar and gzip command combination

• create a compressed archive of the /etc directory.
• Store the archive under /var/tmp using a filename of your choice.

Task 12: Create a directory /direct01

• apply SELinux contexts for /root to it.

Task 13: Set up a cron job for user70

• To search for files by the name “core” in the /var directory and
• copy them to the directory /var/tmp/coredir1.
• This job should run every Monday at 1:20 a.m.

Task 14: Search for all files in the entire directory structure

• That have been modified in the past 30 days and save the file listing in the /var/tmp/modfiles.txt file.

Task 15: Modify the bootloader program and set the default autoboot timer value to 2 seconds.

Task 16: Determine the recommended tuning profile for the system and apply it.

Task 17: Configure Chrony to synchronize system time with the hardware clock. Remove all other NTP sources.

Task 18: Install package group called “Development Tools”

• capture its information in /var/tmp/systemtools.out file.

Task 19: Lock user account user70.

• Use regular expressions to capture the line that shows the lock and store the output in file /var/tmp/user70.lock.

Task 20: Write a bash shell script

• so that it prints RHCSA when RHCE is passed as an argument, and vice versa.
• If no argument is provided, the script should print a usage message and quit with exit value 5.

Task 21: Launch a rootful container and configure it to auto-start via systemd.

Task 22: Launch a rootless container

• As user80 with /data01 mapped to /data01
• using the latest version of the ubi9 image.
• Configure a systemd service to auto-start the container on system reboots without the need for user80 to log in.
• Create files under the shared mount point and validate data persistence.
