Firewalking is totally different, right?

I thought it was AS PATH Inference, though.

It's definitely AS Route Inference!

Wait, are BGP collectors really public? That sounds sketchy!

I’m confused between AS Route Inference and AS PATH Inference. They both sound similar, but I can't recall the specifics.

Firewalking seems more related to probing networks rather than collecting routing info. I’m leaning towards one of the AS options.

I remember practicing a question about routing updates, and AS PATH Inference was mentioned. Could that be the right choice here?

I think the answer might be AS Route Inference, but I'm not entirely sure. It sounds familiar from our discussions on BGP.

I'm a little confused by the wording of this question. Let me re-read it carefully and see if I can eliminate any of the options.

Okay, the key details here are that it relies on BGP collectors and provides routing information publicly. I'm pretty confident C is the right answer.

Hmm, I'm a bit unsure about this one. I'll need to think through the different mapping techniques and see which one matches the description.

I'm torn between A) and C), but I think C) is the way to go. Although, now I'm wondering if 'AS' stands for 'Awesome Sauce' in this context. Hmm, food for thought.

I'm going with C) AS PATH Inference. It's the only one that mentions BGP, which is the key to this question. Plus, it's a much cooler name than 'Path MTU discovery'.

C) AS PATH Inference sounds good to me. I bet the exam writers are trying to trick us with those other options. Nice try, but I'm on to you!

Wait, isn't Firewalking that technique where you try to figure out what's behind a firewall? I'm not sure that's the right answer here.

I'm pretty sure it's A) AS Route Inference. That's the one that uses BGP collectors, isn't it? The others seem a bit too specific.

I'm not sure, but I think Firewalking is more about determining firewall rules rather than mapping Internet routes.
