Question:
What mitigation plan is best for thwarting a DoS attack that is creating a MAC address table overflow?

  • Disable DTP.
  • Disable STP.
  • Enable port security.
  • Place unused ports in an unused VLAN.

Explanation: A MAC address (CAM) table overflow attack, buffer overflow, and MAC address spoofing can all be mitigated by configuring port security. A network administrator would typically not want to disable STP because it prevents Layer 2 loops. DTP is disabled to prevent VLAN hopping. Placing unused ports in an unused VLAN prevents unauthorized wired connectivity.
