Which of the following about inter-AS model A VPRN is FALSE?
It requires the configuration of back-to-back VRFs between ASBR routers in different autonomous systems
It is the most scalable of the Inter-AS models.
Most routers that support VPRN functionality support model A by default.
It uses conventional eBGP to distribute unlabeled IPv4 routes between ASBR routers in different autonomous systems.

Which of the following commands produces the output for the inter-AS model B VPRN?
ASBR1# show router 10 bgp routes vpn-ipv4
ASBR1# show router bgp routes
ASBR1# show router bgp routes vpn-ipv4
ASBR1# show router route-table

For the Carrier Supporting Carrier (CSC) VPRN, which routes are advertised between CSC-CE1 andCSC-PE1?
VPN-IPv4 routes for all PE system addresses in AS 1000
BGP labeled IPv4 routes for all PE system addresses in AS 1000
VPN-IPv4 routes for all PE system addresses in AS 5000
BGP labeled IPv4 routes for all PE system addresses in AS 5000
For a Carrier Supporting Carrier (CSC) VPRN where the customer carrier is an ISP that provides Internet connectivity to its end-customers, which of the following is FALSE?
All traffic exchanged between end-customers is carried over a single CSC VRF.
Customer carrier PE routers residing in different sites must run eBGP between them to exchange customers' routes.
The customer carrier network can be a pure IP network.
MPLS can be used in the customer carrier network to improve scalability.
For a Carrier Supporting Carrier (CSC) VPRN where the customer carrier is a BGP/MPLS VPN Service Provider (SP), which of the following is FALSE?
The customer carrier network must be MPLS-enabled.
If the customer carrier offers VPRN services, PE routers residing in different customer carrier sites must run iBGP between them.
The customer carrier provides Layer 2 and Layer 3 services to its end- customers.
A single CSC VPRN is configured on the network provider to support all services offered by the customer carrier.
Which of the following protocols are supported by the Alcatel-Lucent 7750 SR for the creation of transport tunnels within an autonomous system?
MP-BGP.LDP.RSVP-TE
LDP, RSVP-TE.GRE
MP-BGP.RSVP-TE.GRE
MP-BGP.LDP
MP-BGP only
Which of the following protocols does the Alcatel-Lucent 7750 SR support to signal VPRN service labels?
Targeted-LDP
BGP
MP-BGP
RSVP-TE
Click the exhibit.
The policies shown are configured on an Alcatel-Lucent 7750 SR to implement an extranet VPRN between the main sites of two separate VPRNs. How should these policies be applied?
"Blue-Site1"should be applied as an export policy on the PE attached to the extranet sites of the Blue customer VPRN.
"Red-Site 1"should be applied as an import policy on all the PE routers that are part of the Red customer VPRN.
"Blue-Site 1"should be applied as an import policy on the PE attached to the extranet sites of the Blue customer VPRN.
"Blue-Site1 "should be applied as an export policy on all the PE routers that are part of the Blue customer VPRN.

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-PE1 pops the BGP label and pushes two labels: a VPN label and an MPLS transport label.
CSC-PE2 pops the MPLS transport label and pushes a BGP label.
CSC-CE2 pops the BGP label and pushes an LDP transport label.
