Which two components are required for MPLS Layer 3 VPN configuration? (Choose two.)
For MPLS Layer 3 VPN configuration, it is necessary to use a unique Route Distinguisher (RD) per customer Virtual Routing and Forwarding (VRF) to distinguish the routes of different customers, ensuring their isolation within the shared infrastructure. Additionally, Multiprotocol BGP (MP-BGP) is required for the propagation of customer routes within the provider's backbone, as it supports the carrying of VPNv4 routes which include both the IPv4 prefix and the RD, allowing the VPN routes to be correctly interpreted and routed in the MPLS network.
It can be any routing protocol between CE and PE including static routes

You need a RD and MP-BGP to propagate the customer routes through the MPLS. OSPF between the PE and CE *can* be used and will work fine, but is not needed. CE
CE like the others explained
Definitely C and E
But MP-BGP does not propagate the customer routes, propagate VPNv4 routes
C & E are correct
