Which TCP ports should you allow from the internal network to the perimeter network？（）

单项选择题Your network contains a single Active Directory domain.  You have an Exchange Server 2010 organization that contains a Hub Transport server named Hub1. Hub1 receives all e-mail messages that are sent to your organization from the Internet.  A new company security policy states that domain-joined servers must not be accessible directly from theInternet.  You need to create a message hygiene solution to meet the following requirements： .Comply with the new security policy .Minimize the amount of spam that is delivered to the internal Exchange servers in the organization  What should you do first？（）

A.Deploy an Edge Transport server， and then configure EdgeSync synchronization.
B.Deploy a new Hub Transport server， and then install the anti-spam transport agents.
C.Deploy a new Hub Transport server， and then deploy Active Directory Federation Services （AD FS）.
D.Deploy an Edge Transport server， and then disable Active Directory Lightweight Directory Services（AD LDS）.

单项选择题Your network contains an internal network and a perimeter network. The internal network contains an Active Directory forest. The forest contains a single domain.  You plan to deploy 10 Edge Transport servers on the perimeter network.  You need to recommend a solution for the Edge Transport server deployment. The solution must meet the following requirements： .Allow administrators to apply a single security policy to all Edge Transport servers .Reduce the administrative overhead that is required to manage servers .Minimize the attack surface of the internal network What should you recommend？（）

A.Implement Network Policy and Access Services （NPAS）.
B.Implement Active Directory Federation Services （AD FS）.
C.Create a new Active Directory domain in the internal forest， and then join all Edge Transport servers to the new domain.
