Cisco 350-501 Exam - Topic 10 Question 72 Discussion

A regional MPLS VPN provider operates m two regions and wants to provide MPLS L 3VPN service for a customer with two sites in these separate locations. The VPN provider approaches another organization to provide backbone carrier services so that the provider can connect to these two locations.Which statement about this scenario is true?
D) When BGP is used for both route and label exchange, the neighbor a.b.c.d send-lable command is used under the address family VPNv4 command mode.
A) When edge routers at different regional sites are connected over the global carrier backbone, MP-eBGP must run between the routers to exchange the customer VPNv4 routes
B) When eBGP is used for label exchange using the send label option, MPLS-BGP forwarding is configured under the global ABC CSC PE-to CE interface
C) When IGP is used for route exchange and LDP for label exchange, MPLS is enabled only on the VRF interface on the backbone-earner PE side.

I'm drawing a blank on this one. The wording is tripping me up and I can't quite figure out the difference between these types of schemes. I'll have to make an educated guess and hope for the best.

Option D sounds like the right answer. Using the 'neighbor a.b.c.d send-label' command under the VPNv4 address family is the way to go when using BGP for both route and label exchange.
