All servers on your companys network run Windows Server 2008 R2. All client computers run Windows Vista. The company is planning to virtualize an application that is CPU intensive and that runs only on Windows Vista and Windows 7. 
You need to recommend a virtualization solution that minimizes the use of CPU resources on the server. 
Which technology should you recommend？（）

单项选择题All servers on your network run Windows Server 2008 R2.  You plan to configure multiple highly available virtual machines （HAVMs） on a Hyper-V failover cluster. You need to recommend a storage solution that supports high availability.  Which storage solution should you recommend？（）

A.a direct-attached storage （DAS） device
B.a multipath serial-attached SCSI drive with a witness disk
C.a multipath Fibre Channel logical unit number （LUN） with a witness disk
D.a multipath iSCSI logical unit number （LUN） with Cluster Shared Volumes （CSVs）

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

单项选择题You have a Windows Server 2008 R2 Hyper-V failover cluster.  You manage the virtual environment by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You need to find out whether the failover cluster is properly configured to support highly available virtual machines （VMs）.  Which PowerShell cmdlet should you run？（）

A.Test-Cluster
B.Enable-VMHost
C.Get-VMHostRating
D.Test-ClusterResourceFailure

多项选择题Your network includes the servers shown in the following table.  You manage your existing virtual environment by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You are designing a highly available Hyper-V solution. You need to minimize the downtime of virtual machines （VMs） during maintenance periods. What are two possible ways to achieve this goal？（）

A.Create a host group that contains Server1 and Server2， and place each VM on NFS storage
B.Create a Hyper-V failover cluster of Server1 and Server2， and place each VM on a separate shared iSCSI logical unit number （LUN）
C.Create a Hyper-V failover cluster of Server3 and Server4， and place all VMs on a single Fibre Channel logical unit number （LUN）
D.Create a Hyper-V failover cluster of Server3 and Server4， and place all VMs on a single iSCSI logical unit number （LUN） that is configured as a Cluster Shared Volume （CSV）

单项选择题You have a Windows Server 2008 R2 Hyper-V failover cluster that has 16 nodes.  You plan to load-balance eight virtual machines （VMs） on the Hyper-V failover cluster by using network load balancing （NLB）. You need to ensure that the NLB cluster converges.  What should you do？（）

A.Set the NLB cluster type to Multicast
B.Dedicate a virtual network for all NLB traffic
C.Use static MAC addresses for the parent network adapter
D.Enable spoofing of MAC addresses on the virtual network adapter
