Explanation

The command hostnamectl set-hostname Comptia-WebNode -H [email protected] sets the hostname on the remote server at 192.168.2.14 as root via SSH. The -H (or --host) flag is used to operate on a remote machine, which is appropriate when the administrator is configuring a web server from a management workstation. Option A only displays status. Option B sets an absurdly long hostname (86 'A' characters), which is invalid. Option D uses --transient, which sets a non-persistent runtime hostname that will not survive a reboot.
