单项选择题 Your network contains a Virtualization environment that includes the following： - 10 hosts that run VMware ESX Server 4.0 - Microsoft System Center Virtual Machine Manager - 50 Hyper-V hosts that run Windows Server 2008 R2 Each Virtualization host contains a minimum of 15 virtual machines （VMs）. You need to recommend a solution to ensure that users can create and deploy VMs to any of the virtualization hosts. The VMs must be based on templates created by an administrator. What should you include in the recommendation？（）

单项选择题 Your network includes 40 servers that run Windows Server 2008 R2. You plan to virtualize the servers by using Hyper-V in a failover cluster. Your plan must allow for up to two offline host servers while still maintaining highly available virtual machines. You need to recommend the minimum number of Hyper-V host servers for the cluster. How many servers should you recommend？（）

多项选择题 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？（）
