单项选择题 Your network includes Microsoft Hyper-V Server 2008 R2 servers. Each Hyper-V server runs multiple virtual machines （VMs）. The VM guest operating systems include Windows Server 2003 and Windows Server 2008 R2. You are analyzing VM performance metrics to complete capacity planning for the Hyper-V servers. The performance metrics for the VMs are shown in the following table. You need to identify the VM that is showing indications of reduced performance. Which VM should you choose？（）

单项选择题 Your network contains an Active Directory domain. The functional level of the domain is Windows Server 2008. The domain contains application servers that run either Windows Server 2003， Windows Server 2008， or Windows Server 2008 R2. The network contains 5，000 client computers that run Windows XP Service Pack 3 （SP3）. You plan to deploy Windows 7 to both virtual desktops and physical desktops. All users must be able to run a third-party application named App1 from the Windows 7 client computers. App1 requires monthly updates. Each update will be 2 GB. You need to recommend a solution for App1 that supports the planned deployment. The solution must minimize the amount of bandwidth used to update Appl. What should you include in the recommendation？（）

单项选择题 You are designing a Windows Server 2008 R2 Hyper-V Virtualization environment. Your host servers must have the following elements： - A dedicated management network adapter. - A dedicated virtual network for child iSCSI network traffic. - A dedicated virtual network for child network traffic with VLAN tagging. You need to choose adapters that minimize the host server processing. Which adapters should you choose？（）
