L2PT, huh? I bet that stands for 'Laugh Twice, Panic Thrice' when it comes to dealing with this Metro Ethernet stuff.

Hmm, S-Tag 300? Sounds like we're getting into some fancy network sorcery here. Let's hope the exam doesn't require a degree in quantum physics.

I'm not sure about option A. VXLAN might not be necessary for this scenario with Q-in-Q tagging already in place.

I agree with Jacinta. Option B makes sense for providing Layer 2 connectivity between campus sites.

VXLAN? That's like a secret language for network nerds, right? I'll stick to the basics, thanks.

I think option B is correct because each campus switch must have a C-Tag 300 configured for Q-in-Q tagging.
