Wait, isn't ISP 3 a Tier 1? How would that work?

I think they would have a transit relationship with ISP 3 instead.

ISP 1 and ISP 2 are both Tier 2, so peering makes sense.

I'm a bit confused about the peering vs. transit relationships. I feel like I need to review that section again.

This question feels familiar; I practiced one where Tier 2 ISPs had to connect with Tier 1s. I think B could be right.

I think ISP 1 might have a peering relationship with ISP 2, but I can't recall if it also peers with ISP 3.

I remember that Tier 1 ISPs usually have transit relationships with Tier 2 ISPs, but I'm not sure about the specifics for ISP 1.

I'm feeling pretty confident about this one. The key is understanding the differences between Tier 1 and Tier 2 providers and the typical relationships between them. I'll double-check my answer, but I think B is the correct choice.

Based on the information provided, I think the most likely answer is B. ISP 1 has a peering relationship with ISP 2 and a transit relationship with ISP 3. The Tier 1 providers would likely have a transit relationship with the Tier 2 providers.

I'm a bit confused by the different types of relationships mentioned. I'll need to review my notes on peering and transit to make sure I choose the right answer.

Okay, let me think this through. Since ISP 1 and ISP 2 are Tier 2 providers, and ISP 3 and ISP 4 are Tier 1 providers, the most likely relationship for ISP 1 would be a peering relationship with ISP 2 and a transit relationship with the Tier 1 providers.

But ISP 1 is a Tier 2 provider, so it makes sense for it to have a peering relationship with ISP 2 and ISP 4.

I think the answer is B. ISP 1 likely has a peering relationship with ISP 2 and a transit relationship with ISP 3, since they are a Tier 2 and Tier 1 provider respectively.
