Your virtual environment includes Windows Server 2008 R2 Hyper-V servers. The test and development teams are developing a distributed application. 
The application requires a domain controller， a server that runs Microsoft SQL Server， an application server， and a client computer. The application uses pass-through authentication. You need to ensure that at the time of a failure， the test team can reproduce the error and provide the application in the state in which it existed when the error occurred to the development team for continued analysis. You must achieve this goal while minimizing storage requirements. 
What should you do？（）

单项选择题You have a two-node Hyper-V failover cluster that uses SAN storage. You are designing storage for a new virtualization environment by using Windows Server 2008 R2.  You plan to deploy five virtual machines （VMs） per logical unit number （LUN）. You need to be able to perform a live migration of a single VM while the other VMs continue to run on the host server.  What should you do？（）

A.Use Cluster Shared Volumes （CSVs）
B.Use fixed disks on the SAN storage
C.Boot the virtual machines from iSCSI LUNs
D.Use dynamically expanding disks on an iSCSI LUN

多项选择题You are designing a test environment that uses Hyper-V. The test environment must enable testers to perform the following tasks：  Quickly switch between running states.Re-create a specific state or condition.Return the state of the environment to a specific point in time.Recover from a faulty software update by using the fastest method. You need to ensure that the test environment meets the requirements.  What are two possible tools that you can use to achieve this goal？（）

A.Hyper-V Manager
B.Microsoft System Center Data Protection Manager （DPM） 2007 with SP1
C.Microsoft System Center Virtual Machine Manager （VMM） 2008 R2
D.Microsoft System Center Configuration Manager （SCCM） 2007 with SP3

单项选择题You are designing a Windows Server 2008 R2 Hyper-V environment. You need to be able to dynamically assign new storage to Windows virtual machines （VMs）.  What should you do？（）

A.Use fixed virtual hard disks （VHDs）
B.Install Hyper-V Integration Services on the VMs
C.Install the VMs in Cluster Shared Volumes （CSVs）
D.Use dynamically expanding virtual hard disks （VHDs）

单项选择题You are designing a Windows Server 2008 R2 Hyper-V virtualization environment. Your host servers must have the following elements：  A dedicated management network adapter.A dedicated virtual network for child iSCSI network traffic.A dedicated virtual network for child network traffic with VLAN tagging. You need to choose adapters that minimize the host server processing.  Which adapters should you choose？（）

A.three network adapters that support 802.1p
B.two network adapters that support 802.1q， and one iSCSI host bus adapter
C.two network adapters that support 802.1p， and one network adapter that supports TCP Chimney
D.two network adapters that support 802.1q， and one network adapter that supports Jumbo frames

多项选择题Your virtual environment includes Windows Server 2008 R2 Hyper-V servers. You manage the environment by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You are planning to install an application upgrade.  Testing the production application requires access to the following three virtual machines （VMs）： a domain controller， a server that runs Microsoft SQL Server， and an IIS Web server. You need to test the application upgrade in a virtual environment that is isolated from the production network.  Which two sets of actions should your plan include？（）

A.Pause the three VMs， and copy the .vhd files to the test environment
B.Create a checkpoint of the three VMs， and export the checkpoint to the test environment
C.Import the checkpoint into the test environment， and apply the application update for testing
D.Create three VMs in the test environment， attach the existing .vhd files， and apply the application update for testing
