An administrator wants to conduct an aggressive scan to retrieve version information, run default scripts, and to detect the operating system of the target device. Which Nmap command option should be used?
The '-A' option in Nmap enables aggressive scanning, which combines OS detection, version detection, script scanning, and traceroute. This thorough scanning option is informative for deep network analysis. The '-sn' option is for ping scanning (host discovery), '-p-' scans all 65535 ports, and '-o' is an invalid option as it lacks the specifics for output files like '-oN' or '-oX'.
