Your company has a main office and 10 branch offices. The main office has a firewall. All connections from the branch office are sent through the firewall.
Each office has two Hyper-V hosts that run Windows Server 2008 R2 Service Pack 1 （SP1）. Each host contains 10 virtual machines （VMs）.
You deploy Microsoft System Center Virtual Machine Manager 2008 R2 in the main office.
You need to recommend changes to the firewall to ensure that branch office administrators can manage their local Hyper-V hosts by using System Center Virtual Machine Manager. The solution must ensure that only the required ports are opened.
Which firewall ports should you recommend opening？（）

All servers on your company’s network run Windows Server 2008 R2.

What are two possible CPU recommendations that will achieve this goal？（）
