Your network contains two servers named Server1 and Server2 that run Windows Server 2012.
Server1 and Server2 have the Hyper-V server role installed and are part of a host group named Group1 in Microsoft System Center 2012 Virtual Machine Manager
(VMM).
Server1 and Server2 have identical hardware, software, and settings.
You configure VMM to migrate virtual machines if the CPU utilization on a host exceeds 65 percent.
The current load on the servers is shown following table.
You start a new virtual machine on Server2 named VM8.
VM8 has a CPU utilization of 20 percent.
You discover that none of the virtual machines hosted on Server2 are migrated to Server1.
You need to ensure that the virtual machines hosted on Server2 are migrated to Server1.
What should you modify from the Dynamic Optimization configuration?

A.
The Host Reserve threshold

B.
The Aggressiveness level

C.
The Dynamic Optimization threshold

D.
The Power Optimization threshold

Explanation:
Correct is B
Host Reserve Threshold – defines the amount of resources that are reserved for the Hyper-V Host’s Operating System.
Power Optimization Threshold – defines power optimization settings. Can automatically power a machine on or off according to settings.
Aggressiveness Level: Aggressiveness determines the amount of load imbalance that is required to initiate a migration during Dynamic Optimization.
