Your virtual environment includes a Windows Server 2008 R2 Hyper-V failover cluster. You
manage the environment by using Microsoft System Center Virtual Machine Manager (VMM)
2008 R2. You need to configure the live migration network priorities for all virtual machines
(VMS). What should you do?
A.
In Failover Cluster Manager, edit the properties of a single VM.
B.
In Hyper-V Manager, take each VM offline and edit the settings of each VM.
C.
Enable Cluster Shared Volumes (CSVs).
D.
In Virtual Network Manager, edit the properties of the virtual network.
Explanation:
Managing the network used for Cluster Shared Volumes
Failover clusters include a setting to prioritize the networks used for communication between
the nodes in the cluster and for the network used for CSV traffic. You can identify the
network used for CSV traffic and change the settings of the network using the Windows
PowerShell cmdlet, Get-ClusterNetwork.
Each network in a cluster has two settings for network prioritization – Metric and AutoMetric.
The Metric setting is used to determine the priority of the network (the network with the
lowest value is the most preferred for CSV). The AutoMetric setting identifies whether the
Metric setting was set manually or automatically by the failover cluster. For private networks,
the Metric settings are between 1000 and 10,000, and for public networks, the Metric
settings start at 10,000.
Live migration will be attempted in the order of the networks specified in the list of cluster
networks. If the connection to the destination node using the first network is not successful,
the next network in the list is used until the complete list is exhausted, or there is a
successful connection to the destination node using one of the networks.
Initiate a live migration of a virtual machine You can use either Failover Cluster Manager or
PowerShell to initiate live migration to move a virtual machine from one node to another
node in a failover cluster.
The amount of time it takes to move a virtual machine using live migration is dependent on
the following items:
The network connection speed and bandwidth that is available between the source cluster
node and the destination cluster node.
The load on the source cluster node and the destination cluster node.
The amount of RAM configured for the virtual machine.
