A call is sent by Cisco UCM to Expressway with a URI of 75080001@expc1a.pod8.test.lab. If (7508...)
@expc1a\.pod8\.test\.lab.* is the pattern string, what would be the replacement string of the transform in Expressway to re-write the call so that it becomes 75080001@conf.pod8.test.lab?

Wait, why is there a dot in the replacement? Seems off.

Definitely agree, option C looks right!

The replacement string should be \1@conf.pod8.test.lab

I’m not sure about that, can someone explain the pattern?

I thought it would be option A, but C makes sense too.

I’m leaning towards option A, but I’m not confident about whether the backslash before "conf" is necessary or not.

I feel like option C looks familiar, but I can't recall if we need to include the escape characters for the dots in the replacement string.

I remember practicing a similar question where we had to rewrite URIs, and I think it was important to use the right escape characters.

I think the replacement string should capture the user part correctly, but I'm not sure if I remember the right syntax for the dot escaping.

Ah, I see what's going on here. The pattern string is using a capture group to isolate the username part, and the replacement string is referencing that captured value with \1. Option C looks like the correct choice.

This seems straightforward to me. The pattern string is clearly matching the entire URI, and the replacement string just needs to substitute the domain part with the new value. I'd go with option C.

I'm a bit confused by the syntax of the replacement string. Do I need to include the full domain, or just the part that's changing? I'm not sure if I fully understand how the regex replacement works in this case.

Okay, let me break this down step-by-step. The pattern string is matching the full URI, and I need to replace the domain part with "conf.pod8.test.lab". I think option C is the right answer.

Hmm, this looks like a tricky regex question. I'll need to carefully analyze the pattern string and think through the desired output to determine the correct replacement string.

My eyes are crossing just looking at these regex patterns. I'm going to close my eyes, point at the screen, and hope for the best. C it is!

I think it's C) \\1@conf.pod8.test.lab

Hmm, this question is making my head spin. I'll just go with C and pray that's the correct answer. At least it's not multiple choice with 10 options!

This is a tricky one, but I'm confident that C is the right answer. Can't wait to see the explanations after the exam!

Option D looks interesting, but the exclamation mark at the end seems a bit odd. I'm going with C as the safest choice.
BL

I think C is the safest choice.

I think the correct answer is C. The pattern string \1@conf\.pod8\.test\.lab seems to match the given URI and the replacement string \1@conf.pod8\.test\.lab would rewrite the call as required.

No, it's actually C) \\1@conf.pod8\\.test\\.lab.!
JA

I think it's A) \\1@conf\\.pod8\\.test.lab.@
DE

I agree, C) \\1@conf.pod8\\.test\\.lab seems like the correct answer.

I'm not sure, but I think B) \\1@conf\\.pod8\\.test\\lab.* could also be a possible answer
CH
