Redirects packets from a target host on the LAN intended for another host on the LAN by forging ARP replies?

• A. ARP
• B. DHCP attack
• C. VoIP Call Tapping
• D. Arpspoof

Answer: (D)

On a local network, devices learn how to reach each other by mapping IP addresses to MAC addresses using ARP. That mapping is stored in each device’s ARP cache and ARP replies aren’t authenticated, so they can be forged. By sending forged ARP replies, a malicious host can convince a target that the attacker’s MAC address corresponds to the IP of another host (like the gateway or another device). When the target sends traffic to that IP, it actually goes to the attacker. If the attacker then forwards the traffic to the true destination, the communication remains ongoing while the attacker eavesdrops or manipulates it—this is a man‑in‑the‑middle attack. The situation described—redirecting packets from a target host on the LAN intended for another host on the LAN by forging ARP replies—is ARP spoofing (often implemented with a tool like arpspoof). The other options don’t describe this technique: ARP is the protocol itself, a DHCP attack centers on manipulating IP configuration, VoIP call tapping targets voice traffic, and arpspoof refers to the tool used to perform ARP spoofing.
