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 application availability and without corrupting data.
What should you do first？（）

单项选择题Your company plans to replace the current virtualization solution by using multiple Hyper-V hosts that run Windows Server 2008 R2 Service Pack 1 （SP1）. You are evaluating the power consumption technologies available in Hyper-V. You need to identify which technology will reduce the power consumption of the Hyper-V hosts. Which technology should you identify？（）

A.Second-Level Address Translation （SLAT）
B.CPU Core Parking
C.Multipath I/O
D.a Virtual Desktop Infrastructure （VDI）
E.Microsoft Application Virtualization （App-V）

单项选择题Your network environment includes two Windows Server 2008 R2 Hyper-V servers and one VMware ESX 3.5 host server. You are designing a Microsoft System Center Virtual Machine Manager （SCVMM） 2008 R2 implementation to manage your network environment. SCVMM must be able to perform management tasks that require file transfer operations between your VMware server and your Windows servers. You need to configure the ESX host server to ensure that file transfer operations are encrypted， and follow security best practices. What should you do？（）

A.Use the default root credentials as the virtual machine delegate， and enable SSH root login
B.Create a new virtual machine delegate account， add the account as a member of the VMware Administrators role， and enable SSH root login
C.Create a new virtual machine delegate account， add the account as a member of the VMware Administrators role， and disable SSH root login
D.Use the default root credentials as the virtual machine delegate， and disable SSH root login

单项选择题Your environment includes 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 plan to perform maintenance on the Hyper-V failover cluster. You need to complete the maintenance on the failover cluster while maximizing the uptime of the virtual machines （VMs）. What should you do prior to starting maintenance on each cluster node？（）

A.Use Failover Cluster Manager to perform a quick migration of all VMs to another cluster node
B.Use Failover Cluster Manager to pause the cluster node
C.Use VMM to place the cluster node in maintenance mode
D.Use VMM to pause all VMs and move them to another cluster node

单项选择题Your network contains Microsoft System Center Virtual Machine Manager and 10 Hyper-V hosts. You plan to convert all of the domain controllers to virtual machines （VMs）. You need to recommend a recovery solution for the domain controllers. The solution must meet the following requirements： - Prevent inconsistencies in the Active Directory database. - Provide for the recovery of accidentally deleted Active Directory objects. - Provide for recovery if an administrator incorrectly modifies system settings. What should you include in the recommendation？（）

A.VM snapshots
B.a VM checkpoint
C.Windows Server Backup from within the VMs
D.Windows Server Backup from the Hyper-V hosts

多项选择题Your company’s network environment includes the hypervisors described in the following table. You manage the Microsoft Hyper-V Server 2008 server by using Microsoft System Center Virtual Machine Manager （SCVMM） 2008. You need to be able to manage all the hypervisors by using VMM. Which two actions should you perform？（）

A.Upgrade the VMware ESX 3.0 host servers to VMware ESX 4.0
B.Upgrade the VMware ESX 3.0 host servers to VMware ESX 3.5
C.Install VMware VirtualCenter 2.5 in the existing VMware ESX environment
