Question

you have found the ip address of a host to be 172.125.68.30. you want to see what other hosts are available on the network. which of the following nmap commands would you enter to do a ping sweep? nmap -su 172.125.68. 1-255 nmap -ss 172.125.68. 1-255 nmap -sm 172.125.68. 1-255 nmap -sn 172.125.68. 1-255

Explanation:

A ping sweep (host discovery) in Nmap is done with the -sn flag, which skips port scanning and only checks for active hosts on the target network range. The -sU flag scans UDP ports, -sS is a TCP SYN port scan, and -sM is a TCP Maimon scan, none of which are for ping sweeps.

Answer:

D. nmap -sn 172.125.68.1-255
