Certified Ethical Hacker (CEH) Practice Question

During an internal assessment you connect to a campus access switch and launch the macof module in Yersinia, blasting the switch with 150,000 forged source MAC addresses per minute. From a sniffing standpoint, what is the attacker's primary goal in performing this MAC flooding attack?

  • Force the switch to drop to half-duplex operation, generating late collisions that reveal Ethernet payloads.

  • Exhaust the switch's CAM table so it floods all unknown unicast frames to every port, exposing other users' traffic for capture.

  • Overwrite the default gateway's MAC entry in hosts' ARP caches to redirect traffic through the attacker's machine.

  • Inject spoofed spanning-tree BPDUs to become the root bridge and channel VLAN traffic through the attacker's port.
