HOTSPOT
You plan to implement a virtualization solution to host 10 virtual machines. All of the virtual
machines will be hosted on servers that run Windows Server 2012.
You need to identify which servers must be deployed for the planned virtualization solution.
The solution must meet the following requirements:
• Minimize the number of servers.
• Ensure that live migration can be used between the hosts.
Which servers should you identify?
To answer, select the appropriate servers in the answer area.
Answer: 
Explanation:
Just two server with Hyper-V installed is enough to perform a Live Migration. (Minimize the
number of servers)
The answer depends on the storage solution. You *do* need shared storage for live migration, and if you don’t have a SAN, a third server acting as an iSCSI target (or a SMB 3.0 file server, which is not present here) are required.
Not really. In Win 2012 R2, live migration is possible even between non-clustered nodes with local disks only (aka shared nothing): https://technet.microsoft.com/en-us/library/hh831435%28v=ws.11%29.aspx?f=255&MSPPError=-2147217396
