B sounds tempting, but it's not how it works in VPRN.

A is definitely wrong, labels are not advertised that way.

Wait, I thought LDP was used for labels, not MP-BGP?

I thought the service label had to be manually configured on each PE, but that seems a bit tedious for a VPRN setup.

I practiced a question similar to this, and I feel like the service label is included in the MP-BGP updates, but I could be mixing it up with something else.

I remember something about service labels being prepended to prefixes, but I can't recall if that's specifically for VPRN.

I think the service label is related to MP-BGP, but I'm not sure if it's carried in the updates or advertised differently.

Alright, I think I've got an idea. The "L-64.2" parameter sounds like it could be related to the wavelength range of the optical module. I'll try to match that up with the given options and see if I can determine the correct working window.

I was leaning towards the CloudWatch Logs Insights too, but I feel like some of the questions we did also pointed towards using Athena for log analysis.
