单项选择题 Your environment includes multiple Windows Server 2008 R2 Hyper-V servers. You are designing an administrative strategy for virtual machines （VMs）. You need to ensure that members of the Security Compliance Active Directory Domain Services （AD DS） security group can monitor failed logon events on the VMs. What should you do？（）

单项选择题 Your network contains 10 servers that run Windows Server 2008 R2 Enterprise. The servers are configured as shown in the following table. Server1 and Server2 are members of the same failover cluster. Both servers are connected to a Fibre Channel Storage Area Network （SAN） by using four Fibre Channel connections per server. All virtual machines （VMs） will use virtual hard disks （VHDs） for storage. You need to minimize the number of logical unit numbers （LUNs） that must be created on the Fibre Channel SAN. What should you implement？（）

单项选择题 Your network contains a Virtualization environment that includes the following： - 10 hosts that run VMware ESX Server 4.0 - Microsoft System Center Virtual Machine Manager - 50 Hyper-V hosts that run Windows Server 2008 R2 Each virtualization host contains a minimum of 15 virtual machines （VMs）. You need to ensure that network technicians can manage and create virtual networks on the Hyper-V hosts. The technicians must be prevented from configuring other Hyper-V settings. What should you include in the recommendation？（）
