I beliElmira the correct answer is B) 137000 140000 based on the direction of the update.

I think it's A) 140000 137000 because the update originates from AS 137000.

The AS Path should start with the origin AS, so I think the answer is B) 137000 140000.

I agree with Lavonna, because the AS Path should be in the order it traverses.

But the update travels from AS 137000 to AS 135000 first, so the AS Path starts with 137000.

That leaves us with Option D. This one seems to have the ASes in the correct order, with AS 200 being the first in the path. I think this might be the right answer.

I agree. Option B also seems off, as the ASes are in the wrong order. Option C is just repeating the same AS number, which doesn't make sense in this context.

Okay, let's start by considering the options. Option A seems to have the ASes in the wrong order, so that's probably not the right answer.

Ah, I see. So the update is traveling from AS 137000 to AS 135000, and we need to determine what AS Path is seen by AS 200. This is tricky, but let's work through it step-by-step.

I think the key here is understanding how the 32-bit and 16-bit AS Paths are combined. We need to pay close attention to the order of the ASes in the path.

Hmm, this question is testing our understanding of AS path propagation. I'm not entirely sure about the correct answer, but let's discuss this together.
