Nope, definitely not B. That one's incorrect.

Wait, I thought Type 4 was about the stub area?

A Type 4 LSA is from an ABR to an ASBR, right?

I thought Type 4 LSAs were used to provide routing info to routers outside the area, but I’m confused about whether it’s the ABR or ASBR that originates them.

I feel like Type 4 LSAs are connected to stub areas, but I can't recall if they go into the backbone or the stub area itself.

I remember practicing a question about OSPF LSAs, and I think Type 4 is definitely about ABRs and routes to ASBRs.

I think a Type 4 LSA is related to ASBRs, but I'm not sure if it's about describing routes to them or from them.

I think the answer is B. Duplicating the experience and copying the styles seems like the most straightforward way to recreate the modifications across multiple experiences.

The Interoperability Matrix Tool (IMT) seems like the most logical choice here. That's where I'd start looking for the storage limits information.
