A systems administrator is working on a security report from the Linux servers. Which of the following commands can the administrator use to display all the firewall rules applied to the Linux servers? (Choose two.)
A: `ufw limit` applies rate limiting to a given port. It is meant to prevent an IP from attacking the system, such as an overwhelming amount of SSH login attempts. Typically for Debian systems.
B: `iptables -F` means to flush all the chains in the table, with no chain specified. This would delete all firewalls rules.
C: `systemctl status firewalld` would tell you if the firewall daemon is running, but wouldn't show you any firewall rules.
D: `firewall-cmd --list-all` does as it says. It will list its firewall rules.
E: `ufw status` would show you whether ufw is active or not, and also an "uncomplicated" list of its firewall rules. Typically for Debian systems.
F: `iptables -A` is meant for appending a new firewall rule. It not not a complete command.
