The correct answer is A. Switch then acts as hub by broadcasting packets to all machines on the network. See the full explanation below for the reasoning.
Question
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?
Exhibit
Options
- ASwitch then acts as hub by broadcasting packets to all machines on the network
- BThe CAM overflow table will cause the switch to crash causing Denial of Service
- CThe switch replaces outgoing frame switch factory default MAC address of FF:FF:FF:FF:FF:FF
- DEvery packet is dropped and the switch sends out SNMP alerts to the IDS port
