Wait, isn't it also related to MAC address aging?

Totally agree, it's how switches learn new MACs.

I thought switches just drop packets if they don't know the MAC?

That's definitely frame flooding!

I remember discussing spanning-tree protocol, but I don't think that's what this question is asking. It feels more like frame flooding to me.

This seems similar to a practice question we did on MAC address tables. I feel like frame flooding is the right answer.

I think this might be related to frame flooding since the switch sends the packet to all ports when it doesn't know the MAC address.

I've got this one! The key is that the MAC address isn't in the table, so the switch has to flood the frame. That's the concept of frame flooding, so the answer is C.

I'm a little confused by this question. I know MAC addresses and switching concepts are involved, but I'm not sure which one is the right answer here. I'll have to think about it some more.

Okay, let me think this through. If the MAC address isn't in the table, the switch has to flood the frame to all ports in the VLAN. So I'm going to go with C - frame flooding.

Hmm, I'm not totally sure about this one. I know it has something to do with the MAC address table, but I'm not confident which specific concept it's describing.

C) frame flooding. Yep, that's the one. When the switch doesn't know where to send the frame, it just sends it out to everyone. Kinda like when I forget someone's name and just start waving at the whole room.

B) MAC address table. That's where the switch stores the MAC addresses it's learned, right? Gotta keep that thing up to date or else it's gonna be a wild goose chase.

B) MAC address table. That's correct, the switch uses this table to forward packets to the correct destination.

C) frame flooding. When the switch doesn't know the destination MAC address, it sends the packet out to all ports in the same VLAN.

A) MAC address aging. Yeah, the switch needs to periodically check and update the MAC addresses in its table.

I believe it's C) frame flooding because the switch is broadcasting the packet to all ports.

C) frame flooding - definitely! The switch doesn't know where to send the packet, so it just sends it out to all ports. Classic flooding behavior.
