Ethernet Broadcast MAC Address | Generated by AI
The correct answer is B) FFFF.FFFF.FFFF
Explanation:
In an Ethernet network, a broadcast frame is sent to all devices on the same local network segment (Layer 2 broadcast).
- The destination MAC address for an Ethernet broadcast frame is all ones in hexadecimal: FF-FF-FF-FF-FF-FF (often written as FFFF.FFFF.FFFF).
- This is the reserved broadcast MAC address defined in the Ethernet standard.
Why the others are wrong:
- A) 0000.0000.0000 → This is an invalid or null MAC address (sometimes used as source in special cases, but never for broadcast).
- C) 0100.5E00.0000 → This is the base for IPv4 multicast MAC addresses (not broadcast).
- D) The MAC of the default gateway → This would be a unicast frame, not broadcast.
Correct Answer: B) FFFF.FFFF.FFFF
