Nope, it definitely floods the frame. That's how switches learn!

I thought it just discarded the frame if it didn't recognize the MACs.

Wait, so it saves the source but not the destination? That's weird.

Totally agree, it's flooded to all ports too!

The source MAC gets saved in the FDB, right?

I believe the switch saves the source MAC and floods the frame, but I can't recall if it discards the frame or not.

I'm a bit confused about whether the destination MAC gets saved too. I feel like it only saves the source MAC and floods the frame.

I remember practicing a similar question, and I think the correct answer involves saving the source MAC and flooding the frame to all ports except the one it came from.

I think when a switch sees unknown MAC addresses, it saves the source MAC in the FDB, but I'm not sure if it floods the frame or discards it.

Okay, I've got this. The key is to first identify the sensitive unstructured data across the organization. That's the foundation for everything else, so I'll go with option A.

I've got a strategy - I'll eliminate the options that don't seem relevant, then choose the two that make the most sense.

Regression seems like the right choice here. We're trying to predict a continuous numerical value, not classify into discrete categories. I'll start by exploring the data and identifying the key features that might influence gift card sales.

Hmm, I think the key here is to find a balance between security and usability. Maybe we could explore alternative authentication methods that are more user-friendly.
