Selected Answer: D
The best approach to ensure WAN access availability and redundancy without adding unnecessary complexity or cost is dual homing the remote branches to the MPLS network (Option D). This ensures that the remote branches always have a backup connection, addressing potential failures at the branch level while maintaining high availability for the data center access.

I even think it is D. On old customer of mine required for us to route to different POPs, based on their CE to PE routing, until they reached the DCs. This is simply one of the worst wordings of a question by Cisco at this level. Make ppl guess is not a reflection of good pedagogy. I know my stuff, this wording will not reflect my knowledge.

Selected Answer: A
Additional MPLS provider (which would also require all remote branches to have access to second MPLS provider as well) seems like "gold plating"
