What must a network architect consider for RTs when planning for a single customer full-mesh VPN in an MPLS Layer 3 network?
In an MPLS Layer 3 VPN, Route Targets (RTs) are used to control the import and export of routes between Virtual Routing and Forwarding (VRF) instances. For a single customer full-mesh VPN to operate correctly, the RT must be consistent across all participating sites to ensure that all VRF instances can import and export routes appropriately. Hence, RT must be globally identical within the same VPN.
I would indeed pick B here, as different RT values would make the config really complex without a big benefit.
correct answer its B
also I asked an AI and one of the requirements match with answer B solution
