Resilience against two link faults? Sounds like a real brainteaser. Let's see what the network topology has to say.

Minimum latency, huh? Guess they want us to take the shortest path, even if it's not the most resilient.

I think it could also be a combination of both 1+1 protection and resilience against link faults.
