In an MPLS VPN environment, the QoS marking over the MPLS backbone must be different from the one that is received from the customer. The forwarding on the
egress PE is based on the marking that is set by the ingress PE. Which null label and QoS mode can achieve this?A.
MPLS explicit null with pipe modeB.
MPLS implicit null with short pipe modeC.
MPLS implicit null with uniform modeD.
MPLS explicit null with uniform modeE.
MPLS explicit null with short pipe modeF.
MPLS implicit null with pipe mode

ABC and XYZ MPLS VPN customers are accruing Internet access. Both CEs are sending traffic to the Internet. Which statement about their connectivity is true?
A. Both CEs will have connectivity.
B. Only CE-XYZ will have connectivity.
C. Neither CEs will have connectivity, as both CEs are using the same NATed subnet.
D. Only CE-ABC will have connectivity.
E. Neither CEs will have connectivity, as IAR does not have route back to the NATed subnet.
