You are working on a network design plan for a company with approximately 2000 sites. The sites willbe
connected using the public Internet. You plan to use private IP addressing in the network design, which will be
routed without NAT through an encrypted WAN network. Some sites will be connected to the Internet with
dynamic public IP addresses, and these addresses may change occasionally. Which VPN solution will support
these design requirements?
A. GET VPN must be used, because DMVPN does not scale to 2000 sites.
B. DMVPN must be used, because GET VPN does not scale to 2000 sites.
C. GET VPN must be used, because private IP addresses cannot be transferred with DMVPN through the
public Internet.
D. DMVPN must be used, because private IP addresses cannot be transferred with GET VPN through the
public Internet.
E. GET VPN must be used, because DMVPN does not support dynamic IP addresses for some sites.
