A system administrator needs to obtain information about which server versions are running on open ports of a remote host. However, the administrator must avoid performing an intrusive scan that could disrupt network services. Which of the following commands should the administrator run to best meet these requirements?
nmap -sT --top-ports=10 target_host
nmap --top-ports=100 -sV target_host
nmap -A target_host
nmap -sV --version-light target_host
