Refer to the exhibit that shows a demand matrix, a network topology with candidate links (in thick blue lines and dashed lines), the defined network in thick blue lines and the demand routing (colored numbers in the figure). Every link is 80 km long. Which of the following requirements is supported by this network design with the displayed demand routing?

I agree, D seems right. It shows multiple paths.

I think it's about resilience against two link faults.

It’s a tough choice, but I lean towards resilience.

Resilience is crucial for network stability.

Cost design might be a factor, but not the main one.

I still believe minimizing latency should be a priority.

Yeah, I’d stick with 1+1 protection for safety.
TE

The demand routing looks solid for protection.
KI

True, but it depends on the routing paths.
LA

Resilience against two link faults seems plausible too.
LI
Lindsey

But latency isn't guaranteed with that design.
MI
Miesha

I feel like minimum latency is more important.
ER
Ernie

Agreed, redundancy is key.
TE
Tesha

I think it supports 1+1 protection.

I’m not convinced this is the best for minimum latency.
MA

Totally agree with 1+1 protection!
JU

Wait, can it really handle two link faults? That seems unlikely.
CH

I think it’s more about minimum cost design.
EL

This design supports 1+1 protection for sure.
DE
Dexter

I feel like resilience against two link faults might be a possibility, but I need to double-check how the demand routing is set up in the exhibit.
LA

I vaguely recall that minimum latency focuses on the shortest path, but I can't tell if this network design prioritizes that or something else.

This question seems similar to one we practiced where we had to identify the best routing strategy based on cost. I wonder if minimum cost design is the right answer here.

I think I remember that 1+1 protection means having a backup link for every primary link, but I'm not sure if that's what this design supports.
