An ethical hacker is preparing to scan a network to identify live systems. To increase the efficiency and accuracy of his scans, he is considering several different host discovery techniques. He expects several unused IP addresses at any given time, specifically within the private address range of the LAN, but he also anticipates the presence of restrictive firewalls that may conceal active devices. Which scanning method would be most effective in this situation?

D. ARP Ping Scan ARP (Address Resolution Protocol) Ping is used to resolve IP addresses to MAC addresses within the same broadcast domain (local network). Since ARP does not traverse routers and is not blocked by firewalls within the local network, it provides a reliable method for discovering hosts on the local subnet, even if they are configured to block ICMP and TCP/IP traffic.

Selected Answer: C
TCP SYN Ping (C): This method sends TCP SYN packets to specific ports. It is more stealthy than ICMP-based methods and can bypass firewalls. If a device responds with a SYN-ACK, it indicates the device is active.

actually, D is the correct answer. The presence of the keyword LAN indicates that the ethical hacker performs his testing on LAN, thus ARP Ping Scan is the more convenient scanning technique here.
