Answer A is correct.... " Processor compatibility " setting allows to move 2 VM across hyper V even if they have different version of same vendor's processor. [ Check 2nd image ] https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/dn859550(v=ws.11)

The answer should be yes, once the CPU Compatibility is set. As I understand that some folks have said "NO, because the Hosts are in different Domains", but you're only moving a VM from one Hyper-V Host to another. The question does NOT say which Domain that VM1 is a Member of, or if it even IS a Domain Member! VM1 COULD be either a Linux VM, or a Windows VM in a WorkGroup - in both cases, the Domain should not matter!

When you move VM1, host1 loses connection with switch 1

As per my previous 2 answers. This confirms that indeed the CPU version is the issue. So 'Yes' this will work.

The link clarifies processors from different generation. But does this applies to same generation processors released in different years?

The feature set that is available on a processor varies depending on its make, model, and age

The processor architecture is different between the two hosts, so the solution must enable processor compatibility: Set-VMProcessor TestVM -CompatibilityForMigrationEnabled $true https://docs.microsoft.com/en-us/powershell/module/hyper-v/set-vmprocessor?view=win10-ps

I don't think they asked this question well. My experience with Xeon CPUs is they have a model and revision (E5-1650 v0, E5-1650 v3, E5-2640 v2, etc) or model (Gold 5218R, Gold 6226, Platinum 8253, etc). At the end of the day, if the CPU feature set is different then use Compatibility Mode.
