Which statement about MPLS VPN implementations and traditional peer-to-peer VPN implementations is true?

Which statement about MPLS VPN implementations and traditional peer-to-peer VPN
implementations is true?

A.
MPLS and traditional peer-to-peer VPNs require the service provider to participate in the
customer routing.

B.
MPLS and traditional peer-to-peer VPNs require that the customer routing is transparent to the
service
provider.

C.
MPLS VPNs require the use of link-state routing protocols, traditional peer-to-peer VPN
implementations
require distance vector protocols.

D.
MPLS VPNs are constructed using dynamic routing protocols; traditional peer-to-peer VPN
implementations are constructed using static routes.

Explanation:
The provider IS participating in the customer routing. Peer-to-Peer VPN’s require the SP to
participate in
customer routing, accepting customer routes, transporting them across the SP backbone and

propagating to customer sites. The Provider routers carry all the customers routes, they are easy
to implement, optimum routing is enabled between sites by default as a result.
