You are considering your data center by using Windows Server 2008 R2 Hyper-V servers.
You are performing virtual-to-virtual (V2V) conversions from Microsoft Virtual Server R2 and
Windows ESX environments by using Microsoft System Center Virtual Machine (VMM) 2008
R2. You need to place the virtual machines (VMs) to fully utilize the Windows Server 2008
R2 host servers. What should you do?

A.
Set the placement goal to load balancing.

B.
Implement Windows System Resource Monitor (WSRM).

C.
Set the placement goal to Resource maximization.

D.
Implement Performance and Resource optimization.

Explanation:
When you deploy or migrate a virtual machine to a host, the evaluation and selection of the
most suitable host for the virtual machine is known asvirtual machine placement,
orplacement. During placement, Virtual Machine Manager (VMM) evaluates the suitability of
available hosts and assigns each host a rating of 0stars (not suitable) through 5stars (very
suitable), in half-star increments. Each host’s rating is based on several factors, including the
virtualization software on the host, the hardware and networking configuration of the host
and the virtual machine, the virtual machine’s resource requirements, and whether the virtual
machine is highly available.
A new feature in VMM 2008 R2 is the host compatibility check, which VMM performs before
migrating a virtual machine that is deployed on a Hyper-V host cluster created in Windows
Server 2008 R2. To prevent a migration from failing, the host compatibility check ensures
that the destination host’s hardware, such as CPU model, is compatible with the source host.
VMM uses the Hyper-V compatibility check API in Windows Server2008 R2 and the VMware
compatibility check APIs to ensure that hardware requirements are met for each type of
virtualization software. This feature is not available for failover clusters created in Windows
Server 2008. Using Host Ratings to Select Hosts You can establish customized default
criteria for VMM to use when rating hosts during placement.

This helps you to place virtual machines on the most suitable host. You can specify the
placement goal that VMM should use to calculate hosts ratings. The placement goals are
described in the following table:
You can also specify the relative importance of each of the following resources that VMM
should use when rating hosts:
CPU utilization
Memory utilization
Disk I/O
Network utilization
For example, if you create a Windows Server2008-based virtual machine for developers and
you know that the virtual machine requires significant CPU, however the host has relatively
little hard disk or network resources, you might customize the default ratings to increase the
priority of free CPU while lowering the priority of the hard disk and network.
