Which type of Layer 2 attack can you “do something” for one host?

A.
MAC spoofing

B.
CAM overflow

Explanation:
Cisco implemented a technology into IOS called Port Security that mitigates the risk of a
Layer 2 CAM overflow attack.
Port Security on a Cisco switch enables you to control how the switch port handles the
learning and storing of MAC addresses on a per-interface basis. The main use of this
command is to set a limit to the maximum number of concurrent MAC addresses that can be
learned and allocated to the individual switch port.
If a machine starts broadcasting multiple MAC addresses in what appears to be a CAM
overflow attack, the default action of Port Security is to shut down the switch interface
