Yeah, I agree with Sunshine on this one.

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've seen questions like this before, so I think I know the right approach. I'll carefully consider each option and select the one that best fits the description.

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.
BE

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.

This question seems straightforward, I think I know the answer but I'll double-check the options to be sure.

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'.

I think C) AS PATH Inference is the right choice too.

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!
AN

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.
MA
Mabel 1 year ago
I think D) Firewalking is definitely not the answer, so it must be C) AS PATH Inference.
JU

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.
SU

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

I think AS PATH Inference also relies on BGP collectors to gather routing updates.

Yes, you're right! AS Route Inference uses BGP collectors to collect routing information.

I'm not sure, but AS Route Inference doesn't sound right to me.
TA
Tarra 1 year ago
Hmm, I think it's C) AS PATH Inference. That's the one that uses BGP data to map the internet, right?

↳ replying to Tarra
I believe it's AS Route Inference, but I can see why you would think it's AS PATH Inference.
CA

Yes, you're correct! AS PATH Inference uses BGP data to map the internet.
MA

I agree with Alesia, AS PATH Inference makes sense.
AL

I think the answer is C) AS PATH Inference.
