You are evaluating the use of failover clusters with Cluster Shared Volumes （CSV） for the database servers. You need to recommend which hardware must be purchased.
What should you include in the recommendation？（）

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

单项选择题You deploy two Windows Server 2008 R2 Hyper-V servers. You manage the servers by using Microsoft System Center Virtual Machine Manager （VMM） 2008 R2. You need to ensure that you can restore virtual machines （VMs） in the event of a hardware failure.   What should you do？（）

A.Use a PowerShell script to create a snapshot of each VM. Run the script every 60 minutes on each Hyper-V server
B.Use a PowerShell script to create a checkpoint of each VM. Run the script every 60 minutes on each Hyper-V server
C.Use a PowerShell script to pause， export， and start each VM， and then to copy the export to the opposite Hyper-V server. Run the script once per day on each Hyper-V server
D.Use a PowerShell script to shut down， export， and start each VM， and then to copy the export to the opposite Hyper-V server. Run the script once per day on each Hyper-V server

单项选择题You configure a Windows Server 2008 R2 Hyper-V server with several virtual machines （VMs）. A software vendor releases a software update for an application that runs on only one of the VMs. You need to plan a strategy that enables you to install and test the update without interrupting business operations and without corrupting data.   What should you do first？（）

A.Export the VM
B.Create a snapshot of the affected VM
C.Enable the Windows Volume Snapshot Service on the affected VM
