A malicious user wants to perform an MITM attack on a computer. The computer network configuration is given below: IP: 192.168.1.20 NETMASK: 255.255.255.0 DEFAULT GATEWAY: 192.168.1.254 DHCP…

This command references 192.168.1.1 as the host to impersonate, but the actual default gateway is 192.168.1.254, so no ARP poisoning of the victim toward the real gateway would occur.

The command 'arpspoof -t 192.168.1.20 192.168.1.254' sends spoofed ARP replies to the target host (192.168.1.20) claiming the attacker's MAC address belongs to the default gateway (192.168.1.254), causing the victim to forward all its outbound traffic to the attacker and establishing a man-in-the-middle intercept position for the victim's communications.

This command targets the DHCP server (192.168.1.253) rather than the default gateway (192.168.1.254), meaning general outbound traffic from the victim would not be redirected to the attacker.

This command incorrectly sets the DHCP server as the target and the victim's address as the host to impersonate, reversing the intended roles and failing to intercept the victim's traffic.
