An ICMP ping scan on the subnet 10.0.1.x is described as what?

• A. Intercept all traffic containing HTTP signature
• B. SYN flood a victim
• C. Scan entire subnet for live host
• D. IP Scanner

Answer: (C)

A ping sweep is a network discovery method that checks which hosts are active on a given IP range. An ICMP ping scan to 10.0.1.x sends an ICMP Echo Request to each address in that subnet and notes which ones respond with an Echo Reply. Those replies indicate live hosts, so this technique is described as scanning the entire subnet for live hosts. It isn’t about intercepting HTTP traffic, nor about launching a TCP SYN flood, and while it is a form of IP scanning, the specific purpose here is identifying reachable machines in the subnet.
