For the inter-AS model A VPRN, which of the following is FALSE when CE2 sends an IP packet to 192.168.1.1?

• A.ASBR2 pops one label from the IP packet and label-switches it to ASBR1.
• B.ASBR1 pushes two labels on the IP packet and label-switches the packet to PEL.
• C.PE2 pushes two labels on the IP packet and label-switches the packet to ASBR2.
• D.CE2 forwards an unlabeled IP packet to PE2 via the VPRN interface.

Which of the following about a full mesh VPRN design is FALSE?

• A.Each customer site has a logically direct route to every other customer site.
• B.It requires a full BGP mesh in the provider core.
• C.It provides optimal routing between all sites.
• D.It allows access between all CE devices and all sites participating in the same VRF.

When configuring BGP as the PE-CE protocol on an Nokia 7750 SR, the configuration on the CE is done under the ____________ context and the PE configuration is under the ____________ context.

• A.Service, service
• B.Router, router
• C.Global, router
• D.Router, global
• E.Router, service
• F.Service, router

When configuring the CE with the selected CE-PE routing protocol on an Nokia 7750 SR, which of the following statements is true? (Choose three.)

• A.The routing protocol used must be the same as the routing protocol used at other CE-PE locations in the same VPN.
• B.The protocol is configured under the config>service context
• C.A routing policy may or may not be required depending on the routing requirements and routing protocol
• D.The interface leading to the PE is defined as a protocol neighbor
• E.The protocol is configured under the global router context

Which of the following about inter-AS model B VPRN is TRUE?

• A.Model B supports the exchange of labeled IPv4 routes between ASBRs.
• B.Model B requires the configuration of back-to-back VRFs between the ASBRs in different autonomous systems.
• C.Model B is highly scalable because the VPN-IPv4 routes are neither maintained, nor distributed by, the ASBRs.
• D.There is a dependency between the route target used in different autonomous systems.
