In a company network, a host sends an Ethernet frame destined to the address FF:FF:FF:FF:FF:FF.

What will an Ethernet switch do with this frame?

Show Suggested Answer Hide Answer
Suggested Answer: B

An Ethernet switch will forward the frame to all ports when the destination address is FF:FF:FF:FF:FF:FF. This is because this address is the broadcast MAC address, which means that the frame is intended for all devices on the same LAN segment. The switch does not need to look up its MAC address table to find a matching entry for this address, but simply floods the frame out of all ports except the one where it received the frame. This way, the frame reaches every device on the LAN segment, regardless of their MAC addresses.Reference:Ethernet - Wireshark,Broadcast MAC Address - omnisecu.com

Wait, are you sure? I thought it might drop it.

I feel like I might be mixing this up with how routers handle packets. I think switches behave differently, but I can't recall the specifics right now.

I practiced a similar question where the frame was sent to a broadcast address, and it was definitely forwarded to all ports. So, I lean towards B as well.

I'm not entirely sure, but I remember something about switches dropping frames that aren't destined for any known MAC address. Could that apply here?

I think the answer might be B, since FF:FF:FF:FF:FF:FF is the broadcast address, and switches usually forward broadcasts to all ports.
