Flooding it to all ports? Nah, that's not how it works.

Discarding it seems wrong, so B is out.

Wait, how can it be fragmented? That doesn't make sense.

The frame gets forwarded out the port for the known DA.

I feel like I’ve seen a question where the frame was discarded if the DA was unknown, but this one mentions a known DA, so I think it’s different.

I’m a bit confused about the Ethertype value. Does it really affect how the switch handles the frame?

I remember practicing a similar question where the action depended on whether the DA was known or unknown. I think it’s A.

I think the switch should forward the frame out the port associated with the known destination address, but I'm not entirely sure.

Okay, I've got this. The purpose of a secondary control is to replace primary controls that are either ineffective or can't fully mitigate a risk. That's what option A is describing, and I'm pretty confident that's the right answer.

Hmm, this seems like a tricky one. I'll need to think carefully about the different interfaces a device might have and how ZTP would interact with them.

Okay, I think I've got it. Since these are infinite items that don't have a physical inventory, the Resource item type is the way to go. That makes the most sense for this scenario.
