CompTIA Network+ N10-009 Practice Question

ARP poisoning involves sending fraudulent ARP messages over a local area network, which associates the attacker’s MAC address with the IP address of another host, such as the default gateway. By doing so, the attacker can intercept, modify, or stop data meant for that IP address. This process is used maliciously to intercept and manipulate data, often without the knowledge of the sender or intended receiver. Incorrect answers might seem plausible, but they do not accurately describe ARP poisoning. Incorrect responses refer to MAC spoofing and port security breaches, which, while related to network security, are distinct in nature and mechanism from ARP poisoning.
