Your company has an active directory domain. A server named server1 runs the network access policy server role. You need to disable IPv6 for all connections except for the tunnel interface and the IPv6 loopback interface. What should you do?（）

A.Run the netsh ras ipv6 set command.

B.Run the netsh interface ipv6 delete command.

C.Run ipv6.exe and remove the ipv6 protocol.

D.From the local area connection properties, uncheck internet protocol versions 6 (TCP/IPv6).
