                                      Correct Answer:<\/b> 1<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      Stateless firewall rules evaluate each packet independently based purely on source, destination, and port parameters without tracking session history. Stateful firewall rules maintain connection state tables, meaning an outbound permitted connection automatically tracks and allows legitimate return traffic without requiring explicit bidirectional rule entries.<\/span><\/p>\n
