You manage your Hyper-V environment by using Microsoft System Center Virtual Machine Manager (VMM) 2008 R2.
You plan to perform a virtual-to-virtual (V2V) conversion of several virtual machines (VMs). In VMM, you need to configure the default placement options to consolidate the VMs on the fewest possible host servers.
What should you do?

A.
In Administration view, set the placement goal to Load balancing.

B.
In Administration view, set the placement goal to Resource maximization.

C.
In the Convert Virtual Machine (V2V) Wizard, set the placement goal to Load balancing.

D.
In the Convert Virtual Machine (V2V) Wizard, set the placement goal to Resource maximization.

Explanation:
resource maximization
One of two placement goals during virtual machine placement. When resource maximization is the goal, the suitability of each virtual machine host is rated based on the purpose of consolidating multiple low-utilization workloads on a single host. Virtual machine placement in these cases involves determining the capacity limits for a particular host and placing virtual machines on that host until the limits are reached.
