In this hands-on lab, you will be the `yum` and `rpm` commands to manage packages and package modules on a Red Hat 8 system. You will use the `yum` command to check for and install updates, followed by using `yum module` to install the oldest version of a specific module. You will also use `yum` to remove a previously installed package on the system. The final task will be to use `rpm` to check to see if a package is installed and then install an application using a local rpm file.
