Your environment includes multiple Windows Server 2008 R2 Hyper-V servers.
You manage the virtual environment by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2.
You plan to place multiple Hyper-V servers in the perimeter network （also known as DMZ）. You need to be able to manage the Hyper-V servers by using VMM.
Which two actions should you perform for each server in the perimeter network？（）

Your network environment includes the following elements：
- Two Windows Server 2008 R2 Hyper-V servers
- Two VMware ESX 3.5 servers
- Microsoft System Center Virtual Machine Manager （VMM） 2008 R2
You run several Windows Server 2003 virtual machines （VMs） on your ESX host servers.
You need to convert the ESX VMs to Hyper-V， and you must minimize the downtime during the conversion.
