You manage your virtual environment by using Microsoft System Center Virtual Machine
Manager (VMM) 2008 R2. You monitor the environment using Microsoft System Center
Operations Manager 2007 R2. You have three Windows Server 2008 R2 Hyper-V servers in
a failover cluster. You need to ensure that all virtual machines (VMs) are distributed
automatically across the host servers, and that the VMs will automatically fail over to the
most appropriate host server. What should you do?

A.
Configure Performance and Resource Optimization (PRO) Tips for the Vms.

B.
In VMM, create a host group. Move the three host servers into the host group.

C.
Configure network load balancing on the VMs.

D.
Configure a Fibre Channel logical unit number (LUN) on a SAN device. Configure your
VMs to store the configuration files on the Fibre Channel LUN.

Explanation:
Performance and Resource Optimization (PRO) is available for hosts and virtual machines in
host clusters that are managed by VMM2008 or VMM2008R2. PRO supports workload- and
application-aware resource optimization within a virtualized environment based on
performance and health data provided by PRO-enabled management packs in System
Center Operations Manager2007SP1 or System Center Operations Manager2007R2. PRO
can recommend or automatically implement remedial actions, through PRO tips, to minimize
downtime and accelerate time to resolution. PRO-initiated remediation actions can include
migrating virtual machines within a host cluster to load balance CPU and memory usage on

the clustered hosts. If you have a mission-critical application that is not suitable for migration,
you can exclude the virtual machine on which the workload is running from host-level actions
in PRO. If the host exceeds its CPU or memory threshold, the virtual machine will not be
migrated even if it is using the largest amount of that resource. Even if you exclude an
HAVM from host level PRO actions, you will receive PRO tips for right-sizing the virtual
machine’s configuration.
