Answer: D

Explanation:

James is analyzing an ARP Poisoning attack. This type of attack occurs when an attacker sends falsified ARP (Address Resolution Protocol) messages over a local area network. This results in the linking of an attacker’s MAC address with the IP address of a legitimate computer or server on the network. Once the attacker has inserted their MAC address into the ARP cache of other devices, they can intercept, modify, or stop data in transit, effectively performing a man-in-the-middle or denial of service attack.

Reference: The analysis of ARP packets to identify potential ARP Poisoning is a critical skill for network defenders, as outlined in the EC-Council’s Certified Network Defender (CND) course. The course emphasizes understanding and identifying various network threats, including ARP-related attacks, which are fundamental to maintaining network security123.
