单项选择题 You are designing a Hyper-V solution. You plan to virtualize an application server. The application server requires failover clustering that uses shared storage. You need to choose the correct storage solution. What should you choose？（）

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？（）
