Which type of site-to-site VPN uses trusted group members to eliminate point-to-point IPsec tunnels between the members of a group?
- DMVPN
- GRE
- GETVPN
- MPLS
Explanation: Group Encrypted Transport VPN (GETVPN) uses a trusted group to eliminate point-to-point tunnels and their associated overlay routing. GETVPN is often described as "tunnel-less." Dynamic Multipoint VPN (DMVPN) enables auto-provisioning of site-to-site IPsec VPNs using a combination of three Cisco IOS features: NHRP, GRE, and IPsec VPNs. Generic Routing Encapsulation (GRE) is a tunneling protocol developed by Cisco that encapsulates multiprotocol traffic between remote Cisco routers, but does not encrypt data. An MPLS VPN consists of a set of sites that are interconnected by means of an MPLS provider core network.
