Question #: 29
Topic #: 1

When the switch is working, the device forwards data according to the MAC address forwarding table. Which of the following descriptions is correct?

AThe destination address of the packet is a unicast MAC address, but there is no corresponding entry in the MAC address table, the packet is discarded

BIf the MAC address entry of the device reaches the upper specification limit of the device, the device cannot learn a new MAC address entry, and the data packet is discarded.

CIf the destination MAC address of the packet is the broadcast MAC address, it will be flooded to all ports including the source port.

DThe destination address of the message is a unicast MAC address, then look up the MAC address table, and if found, forward the frame to the corresponding port (excluding the source port)

I'm leaning towards D too. It seems like the most efficient way to forward data based on the MAC address table.

I see your point, However, option D specifically mentions looking up the MAC address table.

But what about option C? Broadcasting to all ports seems logical in some cases.

That's a good point, Celeste. Option C could also be a valid answer based on how switches handle broadcast MAC addresses.

I feel like option C could also be correct. Broadcasting to all ports seems like a common practice in networking.

I agree with you, Florinda. Option D makes sense because it explains how the switch forwards data based on MAC address table.

I don't think so, option C talks about flooding to all ports including the source port.

I'm leaning towards option C as well. It covers the key point that the frame is flooded to all ports, which is the correct behavior for a broadcast MAC address.

Yeah, I agree with Coral. Option D also sounds good, but C is more comprehensive in describing the behavior.

Option C seems to be the correct one. If the destination MAC is a broadcast address, the switch should flood the frame to all ports except the source port.

Haha, option B makes me chuckle. An upper specification limit on MAC addresses? I doubt any modern switch would have that problem.

Okay, let's go through the options. Option A sounds reasonable, but I'm not sure if that's the complete picture.

This question is a good one, testing our understanding of MAC address forwarding in a switch. I'm confident I know the correct answer, but let's hear what the others think.
