Which of the following commands would be used to list all current firewall rules in UFW?

The command that correctly lists all current firewall rules in UFW (Uncomplicated Firewall) is the one that provides a detailed overview of the active rules and their statuses. The command "ufw status verbose" gives a complete overview, including both the status of the firewall (whether it's active or inactive) and detailed information about the current rules applied, such as which ports are allowed or denied and the specific IP addresses targeted by those rules.

While other options may provide some information about the firewall rules, they do not deliver the same level of detail. For instance, "ufw list status" might mislead one to believe it offers a complete listing of rules, but "ufw status verbose" is specifically designed to offer comprehensive insights, which is crucial for effective firewall management. Similarly, terms like "show" and "rules list" are not part of UFW's recognized command syntax for displaying the current state and rules. Thus, "ufw status verbose" is the most appropriate command for listing all current firewall rules.
