All servers on your company’s 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）

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

单项选择题You deploy a Microsoft Hyper-V Server 2008 R2 server. You will back up the server by using Microsoft System Center Data Protection Manager （DPM） 2007 with SP1. Your virtual environment includes the virtual machines （VMs） shown in the following table.   You need to configure the DPM protection group to minimize server downtime during business hours and to provide the best recovery point objective （RPO）. What should you do？（）

A.Set synchronizations to run every 15 minutes during business hours
B.Set synchronizations to run every 30 minutes during business hours
C.Set synchronizations to run every 45 minutes during business hours
D.Perform express full backups every 60 minutes during non-business hours

单项选择题Your environment includes the virtual machines （VMs） shown in the following table.  server Server1 and Server2 communicate with each other over a Hyper-V private virtual network. End-user connectivity to the application server is provided by an external virtual network. You need to monitor network traffic between Server1 and Server2 so that you can create a baseline to appropriately set thresholds for future monitoring. Which counter should you monitor？（）

A.Network Interface Bytes Total/sec
B.Hyper-V Virtual Switch Bytes/sec
C.Hyper-V Virtual Network Adapter Bytes Sent/sec
D.Hyper-V Virtual Network Adapter Bytes Received/sec

单项选择题You have a Windows Server 2008 R2 Hyper-V failover cluster. You manage the cluster by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2.   You plan to monitor the environment by using Microsoft System Center Operations Manager 2007. You need to identify when Hyper-V server load exceeds specific CPU and memory thresholds， and you must rebalance the environment accordingly.  What should you do？（）

A.Configure the Placement settings to maximize resources for each of the Hyper-V servers
B.Configure Performance and Resource Optimization （PRO） to automatically implement PRO tips
C.Configure the Placement settings for CPU and Memory as Very Important for each of the Hyper-V servers
D.Install the Windows Server Operating System Management Pack for Operations Manager 2007， and set the thresholds
