EIGRP can do it too, but BGP is more common.

I definitely remember BGP being important for inter-domain routing, so I’m leaning towards that as the answer.

I'm a bit confused by this question. I know EIGRP, OSPF, and BGP, but I'm not familiar with ISIS. I'll have to guess on this one and hope for the best.

For this type of question, I'd start by thinking about the key characteristics of each routing protocol. BGP is the protocol used for routing between autonomous systems, so that seems like the most likely answer.

Hmm, I'm not entirely sure about this one. I think it might be OSPF, but I'm not 100% confident. I'll have to review my notes on routing protocols.

BGP, hands down. Unless you're a member of the Galactic Empire, then maybe ISIS would work.
