Which VPN architecture option is described as the most common model for secure remote access in the material?

• A. gateway-to-gateway
• B. host-to-gateway
• C. host-to-host
• D. All of the above

Answer: (B)

Secure remote access is typically implemented with a host-to-gateway VPN. In this model, the remote user’s device runs a VPN client that establishes an encrypted tunnel to a centralized VPN gateway at the organization's edge. The gateway authenticates the user, terminates the VPN tunnel, enforces access policies, and routes approved traffic into the internal network. This setup centralizes control, simplifies management, and scales well to many users, while maintaining strong authentication and encryption.

Gateway-to-gateway is used for connecting networks (site-to-site) rather than individual remote users, and host-to-host would require a direct VPN between each pair of devices, which is not practical for broad remote access. All of the above isn’t correct for typical remote-access deployments.
