10 is correct, each router connects to all others in a broadcast domain.

Wait, how can it be 10? That seems high!

Definitely 10, OSPF works that way with broadcast.

I thought it was 6, but I guess I was wrong!

There are 10 fully established neighbors in this case.

I feel like it could be 7, but I’m not confident. I need to double-check how OSPF works with broadcast networks.

I practiced a similar question, and I think it was about 6 relationships for 4 routers. So, with 5 routers, maybe it’s 10?

I'm not entirely sure, but I remember something about OSPF and the formula for neighbor relationships. Is it n(n-1)/2?

I think there are 10 fully established neighbor relationships because each router connects to every other router in a broadcast network.

Easy peasy! With 5 routers, that's 5 choose 2, which is 10 neighbor relationships. I'm confident that's the right answer.

Alright, I think I've got this. In a broadcast network, each router will form a neighbor relationship with every other router. So the total number of neighbor relationships should be the number of routers choose 2.

I'm a bit confused on this one. I know OSPF has special rules for neighbor relationships, but I can't quite remember how they apply in a broadcast network. Gotta review my notes.

Okay, let's see... With 5 routers, I'm guessing the number of neighbor relationships will be less than 20, but more than 5. I'll have to work this out step-by-step.

Hmm, this looks like a tricky OSPF question. I'll need to think through the neighbor relationships carefully.

I'm a bit confused by the RADIUS attribute value setting mentioned in option A. I'll need to double-check the RSSO configuration details to understand if that's the right approach.

Whoa, a petabyte of data? That's a lot to handle. I'll need to really focus on the scalability and performance aspects when evaluating the options.

I'm a bit confused by the wording of the question. What exactly counts as the hospital's "own use" under the law? I'll need to review that concept more closely before selecting an answer.

Let's see, 5 routers, broadcast network type... hmm, I think the answer is C) 7. Gotta love those OSPF neighbor relationships!
HO

Yes, definitely C) 7. OSPF makes managing neighbor relationships easier.
FE

I agree, the answer is C) 7. OSPF neighbor relationships are interesting.
GE

I'm not sure, but I think the answer might be C) 7 because there could be additional relationships established.

Wait, what's an Ethernet and OSPF again? I thought this was a networking exam, not a foreign language test.

Don't worry, networking terminology can be confusing at first!

So, the answer would be B) 6.

In this scenario, there would be 6 fully established neighbour relationships.

Ethernet is a type of network technology, OSPF is a routing protocol.
OD

I agree with Gail, because each router will have 4 fully established neighbour relationships in a network type broadcast.
