Haha, classic networking question. You know, I once saw a switch that would just ignore broadcast frames altogether. That would be a real plot twist for this one!

User 2: Yeah, that makes sense. It's like a broadcast storm waiting to happen.

Oh, I see what you mean, Nadine. But I'm pretty sure the switch will flood the broadcast frame to all 24 ports, regardless of the VLAN configuration. So I'd go with D.

Hmm, I'm not so sure. If the ports are configured for different VLANs, wouldn't the switch only flood the broadcast frame within the same VLAN? I'm leaning towards C.

I think the correct answer is B. The switch will flood the broadcast frame on all ports on which the switch has seen frames from attached devices. That's how Ethernet switches handle broadcast frames.
