I think it could be option C since export policies can affect label activation, but I’m not completely confident.

This question feels similar to one we practiced where the router couldn't reach a specific prefix. I think it might be option B.

Ah, I see. In that case, the correct answer is D. MPLS must be configured before segment routing can run with BGP.

Hmm, I'm a bit unsure about this one. I know synchronization is important, but I'm not sure exactly what happens when it breaks down. I'll have to think it through step-by-step.

Service Abstraction seems like the most relevant principle to apply in this case. By abstracting the services, we could have prevented the duplication of logic across the teams.
