Wait, are you sure B is valid? I thought it had to be exact.

I thought D would match too, but it doesn't start with 65100.

C doesn't match at all, wrong order!

B also matches since it starts with 65100.

Definitely matches A, it's an exact match.

I feel like option D could be a match since it starts with '65100', but I’m not confident about how the regex works in this case.

I practiced a similar question where the regex matched multiple AS numbers, but I can't recall if '65100' alone is enough.

I remember something about regex matching whole strings, but I'm not sure if it can match parts of longer AS Paths.

I think the regex "65100." matches exactly '65100', so I’m leaning towards option A.

I'm a little confused by the AS Path format. I'll need to review my notes on BGP routing to make sure I'm interpreting this correctly. Gotta be careful on this one.

Okay, I got this. The regular expression "65100." means the AS Path must start with "65100" and then have at least one more character. So the answer has to be A.

This looks like a straightforward regular expression matching question. I'll carefully review the options and think through which one matches the given pattern.
NO

Hmm, I'm a bit unsure about this one. I need to make sure I understand the regular expression syntax and how it applies to AS Paths. Let me think this through step-by-step.

Hmm, this looks like a networking configuration question. I'll need to think through the steps to set the system synchronous to the given IP address.

I think the key here is to identify the review type that is most relevant for the start of the Sprint. An inspection for errors or a technical review of the test plan don't seem as directly applicable.

Wait, is this a trick question? I thought the exam was about routers, not magic tricks. Where's the trap door option?

Nah, C) \'65200 65100\' is the winner here. The 65100 is there, and that's all that matters, right?
LA

Exactly, the order of the AS numbers doesn't matter as long as the required AS number is present.
MO
Mohammad

I think so too. It doesn't matter where 65100 is in the AS Path, as long as it's there.
CR
Crista

Yeah, you're right. As long as 65100 is in the AS Path, it will match the regular expression.

D) \'65100 65250 65200\' is the way to go, man. It's got the 65100 and a couple more ASes, just like the regex wants.
JU

D) \'65100 65250 65200\' is the best choice.
EL

C) \'65200 65100\' does not match the regular expression.
TW

B) \'65100 65200\' is also a match.
PE
Percy

A) \'65100\' is the correct answer.
AH
Ahmed

I think B) \'65100 65200'' is the right answer. It's got the 65100 in there, and the additional AS numbers after it.
AN
Anjelica

The correct answer is A) \'65100\'. The regular expression \'65100.\' is looking for an AS Path that starts with 65100 and has one or more additional AS numbers after it.
ON

The correct answer is A) '65100'.
MA

A) '65100'
TA

I'm not sure, but I think the answer might also be C) '65200 65100', as it includes '65100' in the AS Path.
