You administer the virtual machines and the Hyper-Vhost server for a large organization.
All Hyper-V virtual machines must start even when the host server does not have enough physical memory
available.
You need to ensure that all Hyper-V virtual machines start.
What should you do?
A.
Configure the Hyper-V host server to use smart paging.
B.
Configure the virtual machines to run at high priority.
C.
Configure the Hyper-V host server to run at high priority.
D.
Configure the virtual machines to use dynamic memory.
E.
Configure the virtual machines as members of an availability set.
F.
Configure the Hyper-V host server as a member of an availability set.
Answer is A
To provide a reliable restart experience for the virtual machines configured with less minimum memory than startup memory, Hyper-V uses Smart Paging. This memory management method uses disk resources as additional, temporary memory when more memory is required to restart a virtual machine. This approach has advantages and drawbacks. It provides a reliable way to keep the virtual machines running when there is no available physical memory. However, it can degrade virtual machine performance because disk access speeds are much slower than memory access speeds.
To minimize the performance impact of Smart Paging, Hyper-V uses it only when all of the following occurs:
The virtual machine is being restarted.
There is no available physical memory.
No memory can be reclaimed from other virtual machines running on the host.
Smart Paging is not used when:
A virtual machine is being started from an “off state” (instead of a restart).
Oversubscribing memory for a running virtual machine is required.
A virtual machine is failing over in Hyper-V clusters.

Minimum memory configuration with reliable restart operation
As in the previous version of Dynamic Memory, you can configure a minimum memory amount for virtual machines, and Hyper-V continues to ensure that this amount is always assigned to running virtual machines.

I Think D
Hyper-V cant use smart paging
VM should use Dynamic memory to make use of smart paging
The answer is D: Use Dynamic Memory.
Smart Paging is only used when a VM “restarts”, not when it starts from an “off” state. If Microsoft is asking how to guarantee that all the VM’s will start, the answer is
A) Make sure the physical memory available is enough to accommodate the memory assigned to VM’s if using Fixed Memory, or
B) Use dynamic memory in addition to variable startup times, which will allow running VM’s to free up memory so more VM’s may start.
If Microsoft is asking about “restarting” VM’s, then Smart Paging will be used.
Another reason the answer is not A is because Smart Paging is automatically available. You do not have to enable it.
your last remarks is the best one. You don’t configure smart paging at all, it just being used under certain conditions when you use Dynamic memory.
Answer is D.
The question talk about of ensure that all Hyper-V virtual machines start no Hyper-V Host therefore for me the answer is D
