NO.3 Which three statements are correct regarding Layer 2 overlay VPNs and peer-to-peer VPNs?
(Choose three.)
A.Peer-to-peer VPNs require the establishment of virtual circuits to connect the different customer sites
together.
B.Peer-to-peer VPNs require the service provider to participate in the customer routing, accepting
customer routes, transporting them across the service provider backbone, and finally propagating them to
other customer sites.
C.With peer-to-peer VPNs, the service provider is responsible for transport of Layer 2 frames between
customer sites, and the customer takes responsibility for all higher layers.
D.The implementation of Layer 2 overlay VPNs is the traditional switched-WAN model, implemented with
technologies like X.25, Frame Relay or ATM.
E.With Layer 2 overlay VPNs, the service provider is not aware of customer routing and has no
information about customer routes.
F.It is simple to implement Layer 2 overlay VPNs because the Customer Edge (CE) router just needs a
connection to the Service Provider's Provider Edge (PE) router.
Correct:B D E

NO.7 BGP is used as the CE-PE routing protocol in an MPLS VPN. The customer routes are
successfully propagated from the CE router to the ingress PE router, but they are not showing up
on the egress PE router. What is the most likely cause of the problem?
A.There is a BGP-to-MPBGP redistribution error on the ingress PE router.
B.There is a MPBGP-to-BGP redistribution error on the egress PE router.
C.One of the P routers is performing route summarization, breaking the path between the ingress and the
egress PE routers into two LSPs.
D.RTs attached to the CE routes exported by the ingress router are not matched by at least one of the
import RTs on the egress PE router.
E.A route reflector is used to propagate the routes from the ingress PE router to the egress PE router,
thus breaking the LSP.
Correct:D

NO.8 Refer to the diagram. What problem can be caused by the second P router summarizing the
loopback address of the egress PE router?
A.The first P router will be faced with a VPN label which it does not understand.
B.The second P router will be faced with a VPN label which it does not understand.
C.The egress PE router will not be able to establish a label switch path (LSP) to the ingress PE router.
D.A label switch path (LSP) will be established from the ingress PE router to the egress PE router, an
event that is not desirable.
E.The ingress PE router will not be able to receive the VPN label from the egress PE router via MP-IBGP.
Correct:B
