Appendix A: Sample RHCSA Exam 1

Time Duration:3 hours Passing Score:70% (210 out of 300)

All settings performed in the virtual machines must survive system reboots, or you will lose marks.

Setup for Sample Exam 1:

RHEL 9 Server with GUI 20GB disk for the OS with default partitioning. 2x300MB disks and a network interface. (.293GiB for virt-manager) Do not configure the network interface or create a normal user account during installation.

Tasks:

Task 01: Assuming the root user password is lost, and your system is running in multi-user target with no current root session open. Reboot the system into an appropriate target level and reset the root user password to root1234. (Exercise 11-2). After completing this task, log in as the root user and perform the remaining tasks presented below.

Task 02: Using a manual method (create/modify files by hand),

configure a network connection on the primary network device with:
IP address 192.168.0.241/24
gateway 192.168.0.1
nameserver 192.168.0.1

Use different IP assignments based on your lab setup.

No guide needed

Task 03: Using a manual method (modify file by hand), set the system hostname to rhcsa1.example.com and alias rhcsa1. Make sure that the new hostname is reflected in the command prompt.

Done, setting hostname alias was not in notes. But same has adding alias to /etc/hosts.

Task 04: Set the default boot target to multi-user.

No notes needed

Task 05: Set SELinux to permissive mode.

No notes needed

Task 06: Perform a case-insensitive search for all lines in the /usr/share/dict/linux.words file that begin with the pattern “essential”. Redirect the output to /var/tmp/pattern.txt file. Make sure that empty lines are omitted.

No notes needed

Task 07: Change the primary command prompt for the root user to display the hostname, username, and current working directory information in that order. Update the per-user initialization file for permanence.

Done, asked Geekwerkes about clarification for formatting.

Task 08: Create user accounts called user10, user20, and user30. Set their passwords to Temp1234. Make user10 and user30 accounts to expire on December 31, 2023.

no notes needed

Task 09: Create a group called group10 and add user20 and user30 as secondary members.

Task 10: Create a user account called user40 with UID 2929. Set the password to user1234. (Exercise 5-2).

Task 11: Attach the RHEL 9 ISO image to the VM and mount it persistently to /mnt/cdrom. Define access to both repositories and confirm. (Exercise 9-1).

Task 12: Create a logical volume called lvol1 of size 280MB in vgtest volume group. Mount the ext4 file system persistently to /mnt/mnt1. (Exercises 13-6, 13-7, and 14-3).

Task 13: Change group membership on /mnt/mnt1 to group10. Set read/write/execute permissions on /mnt/mnt1 for group members and revoke all permissions for public. (Exercises 6-4 and 6-6; Exercise 4-1 or 4-2).

Task 14: Create a logical volume called lvswap of size 280MB in vgtest volume group. Initialize the logical volume for swap use. Use the UUID and place an entry for persistence. (Exercises 13-13-6, 13-7, and 14-5; Chapter 14, topic: Automatically Mounting a File System at Reboots).

Task 15: Use the combination of tar and bzip2 commands to create a compressed archive of the /usr/lib directory. Store the archive under /var/tmp as usr.tar.bz2. (Exercise 3-1).

Task 16: Create a directory hierarchy /dir1/dir2/dir3/dir4 and apply SELinux contexts of /etc on it recursively. (Chapter 03, topic: Creating Files and Directories; and Exercise 20-2).

Task 17: Enable access to the atd service for user20 and deny for user30. (Chapter 08, topic: Controlling User Access).

Task 18: Add a custom message “This is RHCSA sample exam on $(date) by $LOGNAME” to the /var/log/messages file as the root user. Use regular expression to confirm the message entry to the log file. (Chapter 07, topic: Regular Expressions; Chapter 12, topic: Logging Custom Messages).

Task 19: Allow user20 to use sudo without being prompted for their password. (Chapter 06, topic: Doing as Superuser (or Doing as Substitute User)).

Task 20: Write a bash shell script to create three user accounts—user555, user666, and user777—with no login shell and passwords matching their usernames. The script should also extract the three usernames from the /etc/passwd file and redirect them into /var/tmp/newusers. (Chapter 21, topic: Script12; Chapter 07, topic: Regular Expressions, and Input, Output, and Error Redirections).

Task 21: Launch a container as user20 using the latest version of ubi8 image. Configure the container to auto-start at system reboots without the need for user20 to log in. (Exercise 22-11).

Task 22: Launch a container as user20 using the latest version of ubi9 image with two environment variables SHELL and HOSTNAME. Configure the container to auto-start via systemd without the need for user20 to log in. Connect to the container and verify variable settings. (Exercises 22-8 and 22-11).

\Reboot the system and validate the configuration.
