You Are Working on a Network Design Plan for a Company

You are working on a network design plan for a company with approximately 2000 sites. The sites will be 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.
F) DMVPN must be used, because GET VPN does not support dynamic IP addresses for some sites.
