You work as an IT professional in an international corporation named Wiikigo. In the company, your job is to configure Microsoft Internet Security and Acceleration Server 2006. And you are experienced in performing and managing networks and operational systems. In addition, you are skilled at deploying ISA Server 2006, configuring firewall settings, and optimizing performance of the ISA Server 2006 cache. There are two ISA Server 2006 computers in the company network. The two computers are respectively named ISA01 and ISA02. ISA01 has been configured as the Enterprise Configuration Storage server. ISA01 and ISA02 belong to a single enterprise array. There is a Web server named Web01 that is located in the perimeter network. On Web01, an external Web site is published by you. On the array, an internal Web site is published by you. ISA01 and ISA02 are each configured with a RAID-5 volume. On ISA01, a cache drive is enabled. On ISA01 and ISA02, Cache Array Routing Protocol (CARP) is enabled on the Internal network. You receive report from users saying that it is quite slow to access Web01. You notice that on ISA01 and Web01, physical disk usage is extremely high. ISA Server 2006 needs to be configured to permit faster access to Web01. So what action should you perform to achieve this?

A.
In order to achieve this, a cache drive should be configured on ISA02.

B.
In order to achieve this, the size of the cache drive should be increased on ISA01.

C.
In order to achieve this, for the Web sites on Web01, a content download job should be enabled on ISA02.

D.
In order to achieve this, the HTTP caching Time to Live (TTL) setting should be increased to 50 on ISA01.
