Question
You manage your virtual environment by using Microsoft System Center Virtual Machine Manager (VMM) 2008 R2. You monitor the environment by using Microsoft System Center Operations Manager 2007 R2. You need to enable automatic migration between Hyper-V host servers. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
Options
- ACreate a host group and add the host servers to it.
- BConfigure reserve resources on each host server.
- CUse Intelligent Placement to place VMs on the host servers that have the highest rating.
- DConfigure Performance and Resource Optimization (PRO) Tips.

Explanation
PRO is workload-and application-aware resource optimization. With PRO, we can create policies that act upon tips, provided by SCOM as part of its OS and application monitoring ability, to address potential resource utilization problems. In some ways, PRO is kind of like VMware DRS, but since Hyper-V doesn't provide any live migration functionality. In that regard, it falls far short of matching the DRS functionality. However, where it exceeds VMware DRS is in more detailed knowledge about the applications and services running inside the VM, instead of acting only upon the "external view" of the VM's resource requirements. This is why I think that the VMware acquisition of B-Hive is critical, because it begins to give VMware the same kind of "application awareness" inside the VM so that DRS can act upon service-level agreements or service-level status. PRO also provides an extensible framework (assuming via SCOM's management/monitoring capabilities) to allow hardware vendors to supply hardware monitoring information and other software vendors to provide more detailed information and extensions to PRO. Examples include Brocade (presumably to provide Fibre Channel fabric information), Emulex (Fibre Channel HBA information), EMC (storage array performance information), and HP (server hardware Example, a couple of VMs generating high CPU load on the host. By telling PRO to fix the problem, SCVMM's intelligent placement is invoked and a new host is selected for the VM. The VM is then migrated to the new host.
