Your network contains an Active Directory domain.
You plan to implement a remote access solution that will contain three servers that run Windows Server 2012. The servers will be configured as shown in the following table.
Server3 will support up to 200 concurrent VPN connections.
You need to ensure that all VPN connection requests are authenticated and authorized by either Server1 or Server2. The solution must ensure that the VPN connections can be authenticated if either Server1 or Server2 fails.
What should you do?
A. On Server3, configure a RADIUS proxy. On Server1 and Server2, add a RADIUS client.
B. On Server1 and Server2, add a RADIUS client. On Server3, modify the Authentication settings.
C. On Server3, configure a RADIUS proxy. Add Server1 and Server2 to a failover cluster.
D. On Server2 and Server3, add a RADIUS client. On Server1, modify the Authentication settings.
