I practiced a similar question, and I think the answer is C, but I need to double-check my notes on this.

I’m a bit confused; I thought LERs were more about edge routing, which might make them PE routers?

Lettie 12 months ago

I remember studying about different types of routers, and I feel like LERs are definitely not CE routers.

I think a label-edged router is related to PE routers, but I'm not entirely sure if that's the right answer.

I'm not too familiar with the different router types in MPLS networks. I'll have to guess on this one and hope for the best.

Hmm, I'm a bit confused on the difference between a CE router and a PE router. I'll have to think this one through carefully.

Okay, let me break this down. The question is asking about the type of privacy where the individual controls who has access to their personal information. That sounds like it would be Information Privacy. I'll go with A.

I'm confident I know the right answer here. Storing credentials directly in the workflows is a big no-no, so that leaves the Windows Credential Store or Orchestrator assets.

I'm a bit unsure about the "unique solution" part of the question. Does that mean there's something more I need to do beyond the basic recurring sales line setup? I'll need to explore this further.
