An administrator received a request from a security officer to eliminate a blacklisting set called internal-blocked the company is using in the iptables firewall. Which of the following commands…

ipset swap replaces the contents of one set with another or an empty set, but it does not destroy the original set from the system.

The ipset destroy internal-blocked command permanently removes the entire ipset set named internal-blocked from the kernel. This command frees up the memory used by the set and its entries, effectively eliminating it from the firewall's active configuration and making it unavailable for iptables rules.

ipset del is used to remove a specific entry (like an IP address or network) from a set, not to delete the set itself.

ipset remove is not a standard ipset command for deleting an entire set; del is used for entries, and destroy for the set itself.
