The policy shown is configured on an Nokia 7750 SR to implement an extranet VPRN between the main sites of two separate VPRNs. Route target "target:65100:2" is used for Customer 1 routes, and route target "target:65100:3" is used for Extranet routes. How should this policy be applied?

A.

The policy should be applied as an import policy on the PE connected to the main site of Customer 1.

B.

The policy should be applied as an import policy on all the PEs connected to the sites of Customer 1.

C.

The policy should be applied as an export policy on the PE connected to the main site of Customer 1.

D.

The policy should be applied as an export policy on all the PEs connected to the sites of Customer 1.

An advantage of using BGP as the PE-CE protocol is that route policies are no longer required to control the exchange of routes from BGP to MP-BGP.

A.

True

B.

False

Which command should be used on an Nokia 7750 SR acting as the PE, to view the table containing the BGP routes received from the remote sites?
