Implementing Secure Solutions with Virtual Private Networks (SVPN) — Question 85

An organization wants to implement a site-to-site VPN solution that must be able to support 350 sites with direct communications between all sites, fully encrypt the packet header and payload, and support propagation of routing information over IPsec. Which solution meets these requirements?

Answer options

• A. IPsec full mesh
• B. DMVPN
• C. GETVPN
• D. FlexVPN

Correct answer: D

Explanation

FlexVPN is designed to support complex VPN topologies, including large-scale deployments like the one described. It offers encryption for both packet headers and payloads and can handle the propagation of routing information over IPsec. The other options, while capable of VPN solutions, do not fully meet all the specified requirements for scalability and encryption.
