Your physical environment is configured as shown in the network diagram. The firewall in the diagram is a generic hardware based firewall product.

You are planning to deploy a Windows Server 2008 R2 Hyper-V server to virtualize your current physical environment. You have the following requirements：
- The Web server VM in the perimeter network （also known as DMZ） must be able to communicate with only the SQL Server computer VM through the firewall.
- The SQL Server computer VM must be able to communicate with the Web server VM.
- The client computer VM must be able to communicate with the Web server VM.
- Two dedicated iSCSI networks must available to the SQL Server computer VM.
- A dedicated management interface must be available for the Hyper-V server.
You need to choose the appropriate virtual network configuration.

多项选择题Your environment includes a Windows Server 2008 R2 Hyper-V failover cluster and a single Windows Server 2008 R2 Hyper-V server. You are designing a migration strategy. You need to ensure that you can perform a SAN migration to move virtual machines （VMs） from the single server into the failover cluster. Which two actions should you perform？（）

A.Install Microsoft System Center Virtual Machine Manager （VMM） 2008 R2
B.Install a Virtual Disk Service （VDS） hardware provider
C.Use Cluster Shared Volumes （CSVs） to store the VM files
D.Add the Storage Manager for SANs feature

多项选择题Your network includes Windows Server 2008 R2 Hyper-V servers. You are configuring the servers in a failover cluster that will host highly available virtual machines （HAVMs）. You plan to manage the servers in the cluster by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You need to design a storage solution for the cluster that allows you to migrate virtual machines （VMs） into and out of the cluster by using SAN migration. Which two actions should you include in your design？（）

A.Install a Virtual Disk Service （VDS） hardware provider on each node in the cluster
B.Enable the auto mount feature on each node in the cluster
C.Place all VMs on a dedicated logical unit number （LUN）
D.Place all VMs on a single Cluster Shared Volume （CSV）

单项选择题Your virtual environment includes several Windows Server 2008 R2 Hyper-V servers. Some servers have 16 GB of RAM， and some servers have 32 GB of RAM. Each server has a dedicated management network adapter. Several virtual machines （VMs） are configured on local disk arrays. You plan to enable live migration between all Hyper-V host servers. Your plan must optimize the environment for live migration and enable the live migration of all VMs among all servers. You need to specify the components to add or upgrade. What should you do？（）
