Q3. You are designing a multisite VPN solution for a customer and you are concerned with the additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN. How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in DMVPN? 

A. The GDOI-based VPN requires overlaying a secondary routing infrastructure through the tunnels. 

B. In a GDOI-based VPN, all group members share a common security association. 

C. The GDOI-based VPN requires the provisioning of a complex connectivity mesh. 

D. The GDOI-based VPN leverages the routing protocol to find its peer for tunnel setup.
