You have a Windows Server 2008 R2 Hyper-V failover cluster with a single iSCSI logical unit
number (LUN) and one highly available virtual machine (HAVM). You manage the 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 configure a new virtual machine (VM) by deploying a VHD from the VMM library and
placing the VHD on the existing iSCSI LUN. You create an HAVM configuration, and you
attach the VHD to the configuration. VMM reports the status of the VMs as Unsupported

Cluster Configuration. You need to be able to manage the VMs by using VMM. What should
you do?

A.
Configure Windows System Resource Manager (WSRM) on the Windows Server 2008
R2 cluster nodes.

B.
Configure Performance and Resource Optimization (PRO) on the Windows Server 2008
R2 cluster nodes.

C.
Move the VHD of one HAVM to the system volume of a cluster node.

D.
Move the VHD of one HAVM to a new iSCSI LUN.

Explanation:
The next step for proper network planning and utilization involves iSCSI. Will the VMs be
using iSCSI, or will the host be using iSCSI? Regardless of whether it’s a host or a guest,
you should set aside a separate interface for each instance of iSCSI traffic. If the host is
using iSCSI (for failover clustering, for example), then it should have a separate adapter port
that is different from any adapter port being used for guest VMs using iSCSI. iSCSI can be
used in a VM—in fact, it’s the only way to set up a cluster Note of VMs. It’s recommended
that if a VM is using iSCSI, you should create a separate virtual network to ensure sufficient
bandwidth. Creating Highly Available Virtual Machines Last but not least, one of the most
important provisioning options is the ability to make a VM highly available. Doing so provides
availability in the event that the virtualization host experiences planned or unplanned
downtime. Planned downtime can occur when you perform maintenance on a host;
unplanned downtime can occur when a virtualization host goes down completely for any
reason. In the event of planned downtime, the VM state is saved and migrated to another
virtualization host in a Hyper-V Quick Migration cluster. If a virtualization host crashes that is
a part of a Quick Migration cluster, the VM and associated resources are restarted on
another Hyper-V host in the Quick Migration cluster. To provision highly available VMs, you
first must have set up a Quick Migration cluster Then, you’re almost ready to use SCVMM to
create highly available VMs. You have to make SCVMM aware of the host cluster the same
way you add any host to SCVMM for management. Let’s walk through the steps for making
a VM highly available:
1. Add the Quick Migration cluster to SCVMM via the SCVMM administrator console using
the Add Host option.
SCVMM detects that you’re adding a node to the Quick Migration cluster and adds SCVMM
agents to each host in the cluster. A cluster object is created and available in the SCVMM
console. See Figure for a view of the new cluster object.

2. You’re ready to configure a highly available VM. Open the SCVMM administrator console.
3. Select New Virtual Machine to start the New Virtual Machine Wizard.

4. Select the source for the new VM. Create the new machine with a blank hard drive.
5. Select the name of the VM, the owner of the VM (AD user or group), and enter a
description of the VM.
6. Set up the hardware profile of the VM, including the VHD, the processor count, the
network adapters, and either IDE or SCSI adapters.
7. The most important step is to scroll down to the Availability option and select the check
box to make this VM highly available

8. Select the destination. You can either deploy directly to an existing host or store the VM
on an SCVMM library server.
9. Intelligent Placement determines the best host for the workload using the star rating
system. The host with the most stars represents the best host for placement of this VM
(driven by the Intelligent Placement settings shown in Figure

10. Select a VM path that is in the Quick Migration cluster and a SAN volume.
11. Click Create The Virtual Machine, and verify that the VM is created on the selected
cluster node.
12. Verify the high-availability configuration for the VM by right-clicking the VM and
performing a migration of the VM to another node in the Quick Migration cluster.
