How can you install the Zabbix frontend from the command line?

The correct method to install the Zabbix frontend from the command line involves the use of the package management system appropriate for your Linux distribution. In this case, using the command dnf -y install zabbix-web-mysql or zabbix-web-postgresql is applicable for systems that utilize the DNF package manager, which is commonly used in newer versions of Red Hat-based distributions like Fedora and CentOS Stream.

This command installs the Zabbix frontend package along with dependencies, specifically targeting the MySQL or PostgreSQL database systems for back-end support. The use of -y automatically confirms any prompts that may arise during installation, ensuring a smoother, unattended installation process.

Other commands may pertain to different package managers suited for other Linux distributions, such as APT for Debian-based systems, YUM for older Red Hat-based distributions, or Zypper for openSUSE systems. While those commands are valid for their respective environments, they are not applicable to the DNF-based approach specified in the correct choice. Therefore, the selection of DNF indicates an understanding of both the package manager being used and the requirement for front-end installation in a DNF-compatible environment.
