Pop Quiz: Windows Server 2012: Deploying NAP 802.1X

Applies to the "Configure a Network Policy Server Infrastructure" objective of Exam 70-417.

Q: A company's administrator needs to deploy all necessary services to support the NAP policy enforcement method 802.1X.

Which of the following services are required for NAP 802.1X enforcement? (Choose all that apply.)

  1. DNS
  2. AD DS
  3. AD CS
  4. DHCP

Answer and explanation are below.

Answers are B and C: The Active Directory Domain Services (AD DS) and Active Directory Certificate Services (AD CS) are required services for the NAP enforcement method 802.1X.

Quick Tip: A NAP health policy server requires connectivity to a domain controller to perform PEAP (Protected Extensible Authentication Protocol)-based computer authentication requests. The NAP health policy server also requires a computer certificate to perform the PEAP authentication. After a certificate is acquired, a connection to the certificate server is not required as long as the certificate is valid. However, the AD CS server could continue to be used to issue client computer certificates.


Bonus Question: What methods are available to cleanup Active Directory metadata? (The answer, of course, will be revealed next time!)
