What command is used with YUM to install a package?

The command used with YUM (Yellowdog Updater, Modified) to install a package is "yum install". This command is a fundamental part of managing software packages on RPM-based distributions such as CentOS, Fedora, and RHEL.

When you use "yum install" followed by the name of the package you want to add, YUM connects to the configured repositories to find the specified package. It then downloads and installs the package along with any required dependencies, ensuring that all necessary files and libraries are available for the software to function correctly. This process streamlines package management by automating both the retrieval and installation procedures.

The other options do not represent valid commands within the YUM package management system. "yum add" is not a recognized command for package installation, "yum get" does not exist as an operational command in YUM, and "yum setup" does not apply to the installation process of packages. Thus, "yum install" stands out as the accurate choice for this action.
