Remote control malware was found on a client device, and an unknown attacker was manipulating the network from afar. The attack resulted in the network switches reverting to flooding mode, thereby enabling the attacker to eavesdrop on a significant portion of network communications. After reviewing IDS and traffic logs, you determine that this was accomplished by an attack utility which generated a constant Ethernet frames with random source MAC addresses. What can be done to prevent this attack from occurring in the future?

A Restrict access to DHCP.
B Use a static HOSTS file.
C Use MAC limiting on the switch ports.
D Implement an ARP monitor.

Answer: C Use MAC limiting on the switch ports.
