After running an nmap scan of a system, you receive scan data that indicates the following three ports are open:22/TCP443/TCP1521/TCP What services commonly run on these ports? A.SMTP, NetBIOS, MySQL B.SSH, Microsoft DS, WINS C.SSH, HTTPS, Oracle D.FTP, HTTPS, MS-SQL C. These three TCP ports are associated with SSH (22), HTTPS (443), and Oracle databases (1521). Other ports mentioned in the potential answers are SMTP (25), NetBIOS (137-139), MySQL (3306), WINS (1512), FTP (20 and 21), and MS-SQL (1433/1434). Which of the following tools is best suited to querying data provided by organizations like the American Registry for Internet Numbers (ARIN) as part of a footprinting or reconnaissance exercise? A.nmap B.traceroute C.regmon D.whois D. Regional Internet registries like ARIN are best queried either via their websites or using tools like Whois. Nmap is a useful port scanning utility, traceroute is used for testing the path packets take to a remote system, and regmon is an outdated Windows Registry tool that has been supplanted by Process Monitor. What type of system allows attackers to believe they have succeeded with their attack, thus providing defenders with information about their attack methods and tools?
