Adam, a malicious hacker is sniffing the network to inject ARP packets. He injects broadcast frames onto the wire to conduct Man-in-The-Middle attack.
Which of the following is the destination MAC address of a broadcast frame?

Answer options

• A. 0xDDDDDDDDD
• B. 0x00000000000
• C. 0xFFFFFFFFFFFF
• D. 0xAAAAAAAAAA

Correct answer: C

Explanation

The correct answer is C, 0xFFFFFFFFFFFF, as this MAC address is specifically designated for broadcast frames in Ethernet networks. The other options, A, B, and D, represent invalid MAC addresses or specific host addresses, not meant for broadcasting to all devices on the network.
