Q20. Two MPLS VPN customers want to acquire Internet access. They make use of overlapping address space but do not want to use NAT on the CPEs. Which action satisfies this requirement? 

A. Configure each VRF with a default route in the global table by using a static route toward each customer's range, pointing to the customer interface in the global table. 

B. Configure VRF-aware NAT with a default route in the global table for each VRF that requires it 

C. Configure a separate PE-CE subinterface that terminates in the global routing table on the PE. 

D. Configure the Internet upstream interface inside a VRF, Which becomes an extranet VRF to which customers join and make use of NAT in this VRF.
