A Linux system administrator needs to modify the firewall settings to allow access to a web server service that has been recently configured to listen on a non-standard port, 8443 for secure traffic. Simultaneously, they must ensure that other services remain unaffected by this firewall change. To apply this change immediately and make it permanent for subsequent system reboots, which of the following commands should the administrator execute?

  • iptables -I INPUT -p tcp --dport 8443 -j ACCEPT && service iptables save

  • firewall-cmd --permanent --add-service=https

  • firewall-cmd --permanent --add-port=8443/tcp && firewall-cmd --reload

  • firewall-cmd --permanent --zone=public --add-port=443/tcp
