2. 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.
Answer: BDE
3. Which type of VPN implementation is simple and cost effective because all sites connect only to the PE
router and as a result optimum routing between sites is enabled by default?
