I’m leaning towards option B because it seems like the update would show the originating AS first, but I could be mixing it up with another question we did.
This question feels similar to one we practiced where we had to trace updates through multiple ASes. I think the answer might be A, but I’m not confident.
I'm a bit confused by the 32-bit and 16-bit AS Paths mentioned in the question. I'll need to make sure I understand how those work before I can answer this.
The AS Path seen by AS 200 is D) 200 140000 137000. The question clearly states that the update travels from AS 137000 to AS 135000, which means the AS Path must include 137000.
