R5 learns it through R4's LSA, no doubt!

R4 sends its prefix with a Router LSA.

I feel like the answer has to be related to R4 directly, but I'm torn between the Router LSA and the Inter-Area Prefix LSA options.

I practiced a similar question where R5 learned from an LSA, but I can't remember if it was a Router LSA or an Inter-Area one.

I remember something about Inter-Area Prefix LSAs, but I can't recall if R1 or R4 would originate it for R5 to learn about R4's prefix.

I think R5 learns R4's prefix through a Router LSA from R4, but I'm not entirely sure if that's the right choice.

I'm confident that the correct answer is C. R4 will originate a Router LSA to advertise its system prefix, and R5 will learn about it that way.

Okay, let's think this through step-by-step. R4 is advertising its system prefix into Area 0, so R5 should learn about it through an Inter-Area Prefix LSA originated by R1.

Hmm, I'm a bit unsure about this one. I know OSPF has different LSA types, but I'm not 100% sure which one would be used to advertise the IPv6 system prefix from R4 to R5.

This seems like a pretty straightforward OSPF question. I'll need to think through the LSA types and how they're propagated in the OSPF domain.

B) With a Router LSA originated by R5? More like, 'With a Router LSA originated by R5, and then immediately discarded.'
