Nah, it's not D, that's incorrect.

I thought it would go to all ports, like option D.

Definitely option C! Makes sense.

Wait, why would it only flood on those ports?

The switch floods the frame on ports 2 to 8.

I believe the switch will flood the broadcast frame on ports 2 to 8 since it's in VLAN 100, but I could be mixing it up with how routers handle broadcasts.

I'm a bit confused about how switches handle broadcasts. I feel like it might be B, but I can't recall if it floods to all ports or just the VLAN.

I remember practicing a similar question, and I think the correct answer is that it floods only on the ports within the same VLAN, so maybe C?

I think the switch will flood the broadcast frame, but I'm not sure if it's just on the VLAN or all ports.

I'm a little confused. Wouldn't the switch just discard the broadcast frame since there's no specific destination address? I'm not sure the VLAN configuration is relevant here. I'll have to review my VLAN knowledge before answering this.

Okay, I've got this. The question states the switch is configured with 3 different VLANs, so the broadcast frame should only be flooded to the ports in VLAN 100, which are ports 2-8. Answer C is the correct one.

Hmm, I'm a bit unsure about this one. I know broadcast frames are supposed to be flooded, but I'm not sure if the switch will only flood within the VLAN or across all VLANs. I'll need to think this through carefully.

I think the key here is understanding how VLANs work on a switch. Since the broadcast frame was received on port 1, which is in VLAN 100, the switch should flood it to the other ports in VLAN 100, which are ports 2-8.

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!

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.
