You administer a Windows Essential Business Server 2008 environment. The network contains a Forefront Threat Management Gateway Security Server. The computers on the network run Windows XP Professional, Windows Server 2003, Windows Vista, and Windows Server 2008. You want to configure Network Access Protection (NAP) to create and enforce health requirements policies to define the software and system configurations for computers that connect to the network.

Which computers will support NAP? (Choose all that apply.)

A.
Windows XP Professional

B.
Windows Server 2003

C.
Windows Vista

D.
Windows Server 2008

Explanation:
The options stating Windows Vista and Windows Server 2008 are correct. NAP allows you to create and enforce health requirements policies that define the software and system configurations for computers that connect to the network. NAP enforces health requirements by inspecting and assessing the health of client computers, limiting network access when client computers are deemed noncompliant, and remediating noncompliant client computers for unlimited network access. NAP is only supported by clients that run Windows Vista or Windows Server 2008 operating system.

The options stating Windows XP Professional and Windows Server 2003 are incorrect because NAP is not supported by clients running these operating systems.
