You are a network administrator for Alpine Ski House. The internal network has an Active Directory-integrated zone for the alpineskihouse.org domain. Computers on the internal network use the Active Directory-integrated DNS service for all host name resolution. The Alpine Ski House Web site and DNS server are hosted at a local ISP. The public Web site for Alpine Ski House is accessed at www.alpineskihouse.com. The DNS server at the ISP hosts the alpineskihouse.com domain. To improve support for the Web site, your company wants to move the Web site and DNS service from the ISP to the company’s perimeter network. The DNS server on the perimeter network must contain only the host (A) resource records for computers on the perimeter network. You install a Windows Server 2003 computer on the perimeter network to host the DNS service for the alpineskihouse.com domain.
You need to ensure that the computers on the internal network can properly resolve host names for all internal resources, all perimeter resources, and all Internet resources.

On the DNS server that is on the perimeter network, install a primary zone for alpineskihouse.com.

Configure the DNS server that is on the internal network to conditionally forward lookup requests to the DNS server that is on the perimeter network.
D.
Configure the computers on the internal network to use one of the internal DNS servers as the preferred DNS server. Configure the the TCP/IP settings on the computers on the internal network to use the DNS server on the perimeter network as an alternate DNS server.
E.
On the DNS server that is on the perimeter network, configure a root zone.
