D) MAC-in-MAC, easy peasy. Now, what kind of sandwiches do they serve during the exam break? *rubs belly hungrily*

Wait, isn't H-VPLS Hierarchical VPLS? That's not the same as PBB. I'm going with D) MAC-in-MAC.

I'm pretty sure PBB stands for Provider Backbone Bridges, which is D) MAC-in-MAC. Makes sense since it encapsulates customer MAC addresses within service provider MAC addresses.
