NEW QUESTION 379
Click the exhibit.

A Carrier Supporting Carrier (CSC) VPRN is configured for a customer carrier who is an Internet Service Provider (ISP). If CE1 sends an IP packet to 192.60.100.1, which of the following is FALSE?

PE1 pushes an LDP transport label.

CSC-CE1 pops the LDP label and pushes a BGP label.

CSC-PE1 pops the BGP label and pushes two labels: a VPN label and an MPLS transport label.

NEW QUESTION 380
Click the exhibit.

For the inter-AS model A VPRN. BGP is used as the PE-CE routing protocol. Which of the following statements about the control plane operation is TRUE?

PE1 sends an IPv4 update for prefix 192.168.1.0/27 via MP-BGP to ASBR1.

ASBR1 sends an IPv4 update for prefix 192.168.1.0/27 to ASBR2.

ASBR1 transforms an IPv4 update for prefix 192.168.1.0/27 to a VPN-IPv4 route; allocates VPN label V1 and sends the update to ASBR2.

ASBR2 accepts a VPN-IPv4 update from ASBR1, then sends the update to PE2 via MP-BGP.
