Which technology must be used to implement secure VPN connectivity among company branches over a private IP cloud with any-to-any scalable connectivity?

A. DMVPN

B. FlexVPN

C. IPsec DVTI

D. GET VPN

Answer: D

Explanation:

Cisco‘s Group Encrypted Transport VPN (GETVPN) introduces the concept of a trusted group to eliminate point-to-point tunnels and their associated overlay routing. All group members (GMs) share a common security association (SA), also known as a group SA. This enables GMs to decrypt traffic that was encrypted by any other GM.

GETVPN provides instantaneous large-scale any-to-any IP connectivity using a group IPsec security paradigm.
