What happens when the CAM table becomes full?

Switches maintain a CAM Table that maps individual MAC addresses on the network to physical ports on the switch.

In MAC flooding attack, a switch is fed with many Ethernet frames, each containing different source MAC addresses, by the attacker. Switches have a limited memory for mapping various MAC addresses to physical ports.

What happens when the CAM table becomes full?
A . Switch then acts as hub by broadcasting packets to all machines on the network
B . The CAM overflow table will cause the switch to crash causing Denial of Service
C . The switch replaces outgoing frame switch factory default MAC address of FF:FF:FF:FF:FF:FF
D . Every packet is dropped and the switch sends out SNMP alerts to the IDS port

Answer: A
