John the hacker is sniffing the network to inject ARP packets. He injects broadcast frames onto the wire to conduct MiTM attack. What is the destination MAC address of a broadcast frame?
A.
0xDDDDDDDDDDDD
B.
0xFFFFFFFFFFFF
C.
0xBBBBBBBBBBBB
D.
0xAAAAAAAAAAAA
Explanation:
0xFFFFFFFFFFFF is the destination MAC address of the broadcast frame.
If you’re using a broadcast IP, you should be using a broadcast MAC. Use FF:FF:FF:FF:FF:FF.
When a device sends a packet to the broadcast MAC address (FF:FF:FF:FF:FF:FF), it is delivered to all stations on the local network. It needs to be used in order for all devices to receive your packet at the datalink layer.
