But wouldn’t ISP 1 need to pay for transit with ISP 3?

Wait, how can ISP 1 peer with both ISP 3 and ISP 2? Seems off.

ISP 1 and ISP 2 are both Tier 2, so they likely peer.

I think the answer might be B, but I’m not completely confident. I remember that Tier 2s often peer with each other and transit through Tier 1s.

I’m a bit confused about the Tier 1 and Tier 2 distinctions. Does that mean ISP 1 can only transit through Tier 1 providers?

This question feels similar to one we practiced where we had to identify relationships between ISPs. I think ISP 1 would likely peer with ISP 2 since they're both Tier 2.

I remember studying the differences between peering and transit relationships, but I'm not sure how they apply here.
