Gotta love it when the perfect solution is just a simple protocol like BFD. D all the way!

Haha, I bet the network admin wishes they had implemented BFD from the start! D is definitely the right answer here.

Hmm, I was debating between C and D, but I think D. BFD is the way to go. It's purpose-built for rapid failure detection, which is exactly what they need here.

I'm going with D as well. BFD is the perfect solution for this scenario - it can detect failures much faster than OSPF's normal operation.

I'm not sure, but I think OSPF LFA could also be a good option for faster convergence.

D. BFD sounds right to me. It's a great way to get that sub-second failure detection without having to rely on the slower OSPF convergence process.

I think the answer is D. BFD (Bidirectional Forwarding Detection) is a protocol designed specifically for quick failure detection, which is exactly what the question is asking for.
