Isn't eBGP the standard for those exchanges?

I have a vague memory that option D might not apply to both carriers, but I need to think more about the specifics.

I practiced a similar question about route distribution, and I feel like MP-iBGP is more relevant to PE routers than the others.

I'm feeling pretty confident about this one. The question is asking which BGP type is not applicable to both types of customer carriers, so I'll carefully analyze each option and eliminate the ones that apply to both.

Hmm, I'm a little confused about the differences between iBGP and MP-iBGP in this context. I'll need to review the CSC VPRN configuration details to make sure I understand which BGP types are used for which purposes.

I've got this! The key is to identify which BGP type is not applicable to both BGP/MPLS and Internet service providers in a CSC VPRN setup. I think the answer is D, since MP-iBGP is used between the PE routers, not directly for end-customer and Internet routes.

Okay, let me think this through. eBGP is used between the CSC-CE and CSC-PE routers, and MP-iBGP is used between the CSC-PE routers. I'm a bit unsure about the use of iBGP though.

I'm not too familiar with the history of city planning legislation, so I'll have to make an educated guess on this one. Hopefully, I can at least eliminate a couple of the options.

I'm a bit confused on this one. Is it possible that both B. Clustering and D. High Availability could provide some form of scalability? I'll need to double-check the differences between those options.
