You are using Microsoft System Center Virtual Machine Manager (VMM) 2008 R2 to perform
a virtual-to-virtual (V2V) conversion. You need to place the virtual machine (VM) on the host
server that has the most available disk I/O. Which two actions should you perform? (Each
correct answer presents part of the solution. Choose two.)
A.
Set the placement goal to Load balancing.
B.
Set the placement goal to Resource maximization.
C.
Set the resource importance of the disk I/O to Very Important.
D.
Set the maximum disk I/O per second for the host reserves to 10000.
Explanation:
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.
Setting Host Reserves Host Reservesdefine how much of a host’s resources are to be
reserved for the host operating system. Once these reserves are configured, a virtual
machine cannot be deployed on that host if doing so would require the use of those reserved
resources. The host resources that may be reserved are as follows:
CPU Percentage
Memory
Disk Space
Maximum Disk I/O Per Second (IOPS)
NetworkCapacityPercentage
Host reserves are specified on a host group basis. In addition, the group reserve settings
may also be overridden on a per host basis. To specify the host group reserve settings, right
click on the host group name in the Hosts pane, selectPropertiesfrom the menu and click
theHost Reserve Tabsin theHost Group Propertiesdialog as illustrated in the following figure:
In order to override the group host reserve settings, right click on the host in the list,
selectPropertiesand click onReservesin the resulting dialog.
