I’m leaning towards resilience against two link faults, but I need to double-check how the topology supports that requirement.

The minimum cost design seems like a possibility, but I feel uncertain about how the demand routing impacts that.

I remember discussing 1+1 protection in class, but I can't recall if that applies to this specific network design.

I think this question is similar to one we practiced about network resilience, but I'm not entirely sure how to apply it here.
