Your network contains an Active Directory domain named contoso.com. Contoso.com contains three servers. The servers are configured as shown in the following table.
You plan to give users access to the files shares on Server2 by using DirectAccess.
You need to ensure that you can deploy DirectAccess on Server3.
What should you do?
A.

B.
Add a static IPv6 address to Server2.
C.
Upgrade DC1 to Windows Server 2008 R2.
D.
