Your network consists of a single Active Directory domain. The network contains an ISA Server 2006 computer named ISA1. Client computers on the network consist of Windows XP Professional computers, UNIX workstations, and Macintosh portable computers. All client computers are domain members. You configure ISA1 by using the Edge Firewall network template. You manually configure ISA1 with access rules to allow HTTP and HTTPS access to the Internet. You configure ISA1 to require all users to authenticate. You need to provide Internet access for all client computers on the network while preventing unauthorized non-company users from accessing the Internet through ISA1. You also want to reduce the amount of administrative effort needed when you configure the client computers. What should you do?

A.
Configure all client computers as Web Proxy clients. Configure Basic authentication on the Internal network.

B.
Configure all client computers as Web Proxy clients. Configure Basic authentication on the Local Host network.

C.
Configure all client computers as SecureNAT clients. Configure Basic authentication on the Internal network.

D.
Configure the Windows-based computers as Firewall clients. Configure the non-Windowsbased computers as Web Proxy clients. Configure Basic authentication on the Local Host network.
