What is the behavior of a switch as a result of a successful CAM table attack?
A
The switch will forward all received frames to all other ports.
B
The switch interfaces will transition to the error-disabled state.
C
The switch will drop all received frames.
D
The switch will shut down.
Explanation: 

Detailed explanation-1: -Explanation: As a result of a CAM table attack, a switch can run out of memory resources to store MAC addresses. When this happens, no new MAC addresses can be added to the CAM table and the switch will forward all received frames to all other ports.

Detailed explanation-2: -Shutdown. In the event that the switch port receives more MAC addresses than the configured maximum, the switch will shutdown the switch port. This is the default action mode.

Detailed explanation-3: -An ARP spoofing attack can be launched by running software such as Dsniff, Cain and Abel, or Ettercap from a computer attached to the same switch as the target.

Detailed explanation-4: -As a switch receives frames from different devices, it is able to populate its MAC address table by examining the source MAC address of every frame. When the MAC address table of the switch contains the destination MAC address, the switch is able to filter the frame and forward out a single port.
