Question 14 of 25

15. o prevent hackers from attacking user devices or networks using MAC addresses, you can configure MAC addresses of untrusted users as blackhole MAC addresses to filter out such invalid MAC addresses. When receiving a packet whose source or destination MAC address is a blackhole MAC address on a device, the device discards the packet.
