RHCSA Practice Exam A

General Notes

Here are some tips to ensure your exam starts with a clean environment:

  • You do not need external servers or resources.
  • Do not register or connect to external repositories.
  • Install a new VM according to the instructions in each practice exam.
  • No sample solutions are provided for these practice exams. On the real exam, you need to be able to verify the solutions for yourself as well.
  • You should be able to complete each exam within two hours.

After applying these tips, you’re ready to get started. Good luck!

Tasks

  1. Install a RHEL 9 virtual machine that meets the following requirements:
    1. 2 GB of RAM
    2. 20 GB of disk space using default partitioning
    3. One additional 20-GB disk that does not have any partitions installed
    4. Server with GUI installation pattern

  2. Create user student with password password, and user root with password password.

    Do not register your system with subscription-manager, and remove all references to external repositories that may already exist.

  4. Reboot your server. Assume that you don’t know the root password, and use the appropriate mode to enter a root shell that doesn’t require a password.
    Set the root password to mypassword.

  5. Set default values for new users.
    Set the default password validity to 90 days, and set the first UID that is used for new users to 2000.

  6. Create users edwin and santos and make them members of the group livingopensource as a secondary group membership.
    Also, create users serene and alex and make them members of the group operations as a secondary group.
    Ensure that user santos has UID 1234 and cannot start an interactive shell.

  13. Install the vsftpd service and ensure that it is started automatically at reboot.

  14. Create a container that runs an HTTP server.
    Ensure that it mounts the host directory /httproot on the directory /var/www/html.

  15. Configure this container such that it is automatically started on system boot as a system user service.

  16. Create a directory with the name /users and ensure it contains the subdirectories linda and anna.
    Export this directory by using an NFS server.

  17. Create users linda and anna and set their home directories to /home/users/linda and /home/users/anna.
    Make sure that while these users access their home directory, autofs is used to mount the NFS shares /users/linda and /users/anna from the same server.
