D seems off, VTP domains don't really work that way.

Wait, can VLAN IDs really be reused like that? Sounds risky.

Hmm, I'm a bit unsure about this one. The options seem pretty similar, so I'll need to think it through carefully. Maybe I'll start by eliminating the ones that don't seem to fit the description.

Account Link seems like the most logical choice here. That's the object I'd use to associate an account with a specific price list in Salesforce B2B Commerce.

This seems like a straightforward question about the characteristics of a single-homed AS. I'll start by reviewing what I know about single-homed ASes and then carefully consider each option.
