A.

Explanation:
DirectAccess With Windows Server 2008 R2 requires:
* Public key infrastructure (PKI) to issue computer certificates.
* One or more DirectAccess servers running Windows Server 2008 R2 with two network adapters:
one that is connected directly to the Internet, and a second that is connected to the intranet.
* On the DirectAccess server, at least two consecutive, public IPv4 addresses assigned to the
network adapter that is connected to the Internet.
* DirectAccess clients running Windows 7 or Windows 8 “Enterprise” edition clients
* At least one domain controller and Domain Name System (DNS) server running Windows Server
2008 SP2 or Windows Server 2008 R2.
Note: DirectAccess, also known as Unified Remote Access, is a VPN-like technology that provides
intranet connectivity to client computers when they are connected to the Internet. Unlike many
traditional VPN connections, which must be initiated and terminated by explicit user action,
DirectAccess connections are designed to connect automatically as soon as the computer connects
to the Internet. DirectAccess was introduced in Windows Server 2008 R2, providing this service to
Windows 7 and Windows 8 “Enterprise” edition clients.
