You have three Windows Server 2012 R2 servers that are set up as a Hyper-V cluster. You use System Center
2012 R2 Virtual Machine Manager to manage the Hyper-V environment.
Users report that when a Hyper-V host server becomes overloaded, the performance of the virtual machines is
unacceptable.
You need to analyze workloads and automatically migrate virtual machines from overloaded host servers to
host clusters that have available capacity.
What should you configure?
A.
Performance and Resource Optimization (PRO)
B.
Placement Rules
C.
shared .vhdx file
D.
Dynamic Optimization
During Dynamic Optimization, VMM migrates virtual machines within a host cluster to improve load balancing among hosts and to correct any placement constraint violations for virtual machines.
Dynamic Optimization can be configured on a host group, to migrate virtual machines within host clusters with a specified frequency and aggressiveness. Aggressiveness determines the amount of load imbalance that is required to initiate a migration during Dynamic Optimization. By default, virtual machines are migrated every 10 minutes with medium aggressiveness. When configuring frequency and aggressiveness for Dynamic Optimization, an administrator should factor in the resource cost of additional migrations against the advantages of balancing load among hosts in a host cluster. By default, a host group inherits Dynamic Optimization settings from its parent host group.
Dynamic Optimization can be set up for clusters with two or more nodes. If a host group contains stand-alone hosts or host clusters that do not support live migration, Dynamic Optimization is not performed on those hosts.
