多项选择题Your network includes Windows Server 2008 R2 Hyper-V failover clusters that support highly available virtual machines （VMs）.  You manage virtual machines by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You are planning to deploy a large number of VMs to the failover clusters. All VMs must remain available when one node of each cluster is offline. You need to determine the best placement for the new VMs among the clusters.  Which two actions should you perform？（）

A.For each cluster， set the cluster reserve to 1
B.In each cluster， place one host server in maintenance mode
C.Determine the placement for each VM by using the data that is generated by running the Get-VMHostRating PowerShell cmdlet
D.Determine the placement for each VM by using the data that is generated by running the Get-VMPerformance PowerShell cmdlet

单项选择题All servers in your environment run Windows Server 2008 R2. You are planning a Microsoft System Center Virtual Machine Manager （VMM） 2008 R2 Self-Service Portal deployment.   You need to ensure that members of the Security Compliance group can create new virtual machines （VMs）.  You install the VMM 2008 R2 Self Service Portal and add the Security Compliance group to the Self Service host group.  What should you do next？（）

A.Assign the computer accounts for all Hyper-V servers the Read permission to the library share and NTFS folders. Grant the Log on as a service right to the Security Compliance group
B.Assign the service account for the Hyper-V Image Management Service the Read permission to the library share and NTFS folders. Grant the Log on as a service right to the service account for the Hyper-V Image Management Service
C.Configure the self-service user role to create new VMs. Add the Security Compliance group to the self-service user role. Grant members of the self-service user role access to the library share
D.Configure constrained delegation for the Security Compliance group on the library server. Grant the Log on as a service right to the service account for the Hyper-V Image Management Service

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？（）

A.three
B.four
C.five
D.six

单项选择题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？（）

A.Snapshot and export all servers
B.Snapshot and export only the application server
C.Snapshot the application server， and back up the SQL Server database
D.Snapshot and export only the domain controller and the client computer

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
