You are the network administrator for westsim. com. The network consists of a single domain. All the servers run Windows Server 2016. All the clients run Windows 10. There is one main office located in Chicago. The main office is protected from the internet by a perimeter network. A server named VPN1 located in the perimeter network provides VPN remote access for external clients. A server named NPS1 has the Network Policy Server (NPS) role installed and provides RADIUS services for VPN1. NPS1 is located in the perimeter network and is configured to use Active Directory for authentication requests. There are three domain controllers on the internal network. A new company policy requires that the firewall between the internal network and the perimeter network be configured to allow traffic only between specific IP addresses. The amount of internal servers that can be contacted from the perimeter network must be kept to a minimum. You need to configure remote access to minimize the number of servers on the internal network that can be contacted by servers on the perimeter network. Your solution should not impact the availability of remote access services. What should you do?
