  ARP cache poisoning ARP (Address Resolution Protocol) cache poisoning, also known as ARP spoofing, is an attack method that intercepts traffic on a switched network. In an ARP cache poisoning attack, an attacker sends forged ARP messages to associate their MAC address with the IP address of another legitimate device on the network. As a result, traffic meant for the legitimate device is redirected to the attacker's system, allowing them to intercept and potentially modify the traffic.

  Correct answer: B DHCP snooping is a security mechanism used to prevent rogue DHCP (Dynamic Host Configuration Protocol) servers from providing incorrect or malicious IP configuration information to network clients. It does not directly intercept network traffic.
