Your network contains two servers that run Windows Server 2012.
The servers are members of a failover cluster.
Each server has 32 GB of RAM and has the Hyper-V server role installed.
Each server hosts three highly available virtual machines.
All of the virtual machines have an application named App1 installed.
Each of the virtual machines is configured to have 4 GB of memory.
During regular business hours, the virtual machines use less than 2 GB of memory.
Each night, App1 truncates its logs and uses almost 4 GB of memory.
You plan to add another three virtual machines to each host.
The new virtual machines will run the same load as the existing virtual machines.
You need to ensure that all of the virtual machines can run on one of the Hyper-V hosts if a single host fails.
What should you do?

A.
From the properties of each Hyper-V host, modify the Allow virtual machines to span NUMA nodes.

B.
From the properties of each virtual machine, modify the NUMA Configuration -Maximum amount of memory setting.

C.
From the properties of each virtual machine, modify the Smart Paging File Location.

D.
From the properties of each virtual machine, modify the Dynamic Memory settings.

Explanation:
certbase notes:
We need to ensure that all 12 virtual machines can run in an emergency on a Hyper-V host. The memory that is allocated to the VMs currently (12 x 4 GB = 48 GB),
but exceeds the physically existing memory of a single host. The problem can be solved by the configuration of the dynamic memory allocation:
