Haha, who cares about the DR and BDR? I'm just going to pick the funniest-sounding option, which is C. FortiGate first checks the OSPF ID to elect a DR. Classic!

Wait, what's a FortiGate? I thought this was about OSPF, not FortiGates. Anyway, I'm going with Option D.

I'm pretty sure Option B is correct. Non-DR and non-BDR routers only form full adjacencies with the DR, not with each other.

And the BDR is ready to take over if the DR fails, ensuring network stability.

That makes sense, the DR and BDR play important roles in OSPF multi-access networks.

I disagree, I believe the answer is D) Non-DR and non-BDR routers send link state updates and acknowledgements to 224.0.0.6.

Option D is definitely the correct answer. Non-DR and non-BDR routers send link state updates and acknowledgements to 224.0.0.6, which is the ALL-DROTHERS multicast address.

That makes sense. It's important for non-DR and non-BDR routers to send updates to the ALL-DROTHERS address.
