The attack method that intercepts traffic on a switched network is ARP cache poisoning, which is option B.
Switched networks operate by forwarding packets between network devices using their Media Access Control (MAC) addresses. In order to determine the MAC address of a destination device, a sending device will typically send an Address Resolution Protocol (ARP) request to the network, asking for the MAC address of the device associated with a particular IP address. Once the receiving device responds to the ARP request, the sending device caches the MAC address in its ARP table for future use.
ARP cache poisoning, also known as ARP spoofing, is an attack method in which an attacker sends fake ARP messages to the network, associating the attacker's MAC address with the IP addresses of other devices on the network. By doing so, the attacker can intercept and modify traffic meant for those devices, effectively becoming a "man-in-the-middle" on the network.
By intercepting network traffic, the attacker can potentially steal sensitive information, inject malicious code into network traffic, or launch further attacks against other devices on the network. It is important for network administrators to be aware of this attack method and take steps to mitigate it, such as implementing secure ARP protocols, regularly monitoring network traffic for unusual behavior, and using intrusion detection systems to detect and alert on ARP cache poisoning attempts.
