You plan to implement four Hyper-V hosts named Server1， Server2， Server3， and Server4. The Hyper-V hosts will have the following configurations：
-Server3 will host one virtual machine （VM）.
-Server4 will host four VMs.
-Serverl and Server2 will be clustered in a Hyper-V host cluster.
-The Hyper-V host cluster will host two VMs.
-All VMs will run Windows Server 2008 R2 Standard.
You need to recommend which operating system must be installed on each Hyper-V host. The solution must minimize licensing costs.
Which operating system should you recommend for each Hyper-V host？
To answer， drag the appropriate operating system to the correct Hyper-V host in the answer area.

Your network contains four Hyper-V servers that run Windows Server 2008 R2 Service Pack 1 （SP1）. Each Hyper-V server contains one virtual machine （VM）. The Hyper-V servers are configured as shown in the following table.

You need to recommend a backup strategy for each VM that meets the following requirements：
-Backs up all data.
-Minimizes the size of the backups
What should you recommend？
To answer， drag the appropriate backup strategy to the correct VM in the answer area.
