I think the answer is A. I found no reason the VM cannot be migrated after replacing the CPU.

There is one reason this would not work. The pin layout of a 2012 XEON is not the same as a 2016 XEON. You would not be able to just replace the CPU, it would be a whole mainboard and major subsystem replacement needed.

Also even if the pin layout was the same, it would be unlikely that the southbridge on the mainboard would be compatible with chips of such different architectures.

you have two option: 1- processor compatibility https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-r2-and-2012/dn859550(v%3Dws.11) 2: replace CPU so answer is YES

The correct answer is B (NO) Explanation: The compatibles cpus must have the same socket (same number of pins of the CPU). The zocalo is almost the same in very close years INTEL XEON 2012: Socket BGA1284 Socket 1155 Socket 1356 Socket 2011 INTEL XEON 2016: Socket BGA1440 Socket 2011-1 Socket 2011-3 Ref: https://www.cpu-world.com/info/Intel/Intel_Xeon.html

"a processor that is identical to the processor in Host2" iDENTICAL is identical , same specs, same model. So.... A is correct. B will be the one only if this is one of those questions that Microsoft want to be correct.

I agreed with you originally. But i don't think the exam is expecting you to know intel sockets. You are correct. You can't change cpus because they're different sockets. But the question told us that we did in fact replace them. I didn't really say how. We can't replace them if they're different sockets, so we would have to replace the motherboard as well. And we did replace the cpu. I think this question is really about knowing that you can't use cpus with different feature sets without using the compatibility settings. So i'm going to throw a "Yes".

Guys, ignore the CPU. They’re both intel, you need to exposevirtualprocessor and it’ll be fine. But even then the switches HAVE to have identical switch names for live migration to work.

The answer should be A. The CPU is the only potential issue here and that has been resolved. The domain/sub-domain issue is not relevant if there is domain trust in place, which I would assume there is.

I'm very confused on this. If processor compatibility needs to be configured because the processors are different is the correct answer. If the processors are the same, why would you need to configure any compatibility, they would be the same. Thus eliminating the only reason why live migration wouldn't work in a different way. Making this a correct answer if I understand correctly. Any reason why you would still have to configure processor compatibility?

if you replace the processor, then you don't need to set compatibility. Compatibility is only needed if the CPU manufacturer is the same, but the versions are different. There is also an automatic trust between parent and child domains, so in my opinion, the answer here is A.

Think about this. If you can make this work by enabling processor compatibility. Then why would you go and spend hundreds to thousands of dollars (you will likely also have to change the main board and ram) to solve this problem. That is why this is not the solution. Because it is a very bad business decision on the part of a technician.

I think in this case if you replaced the processor, you'd render the vm incapable of booting. The VM won't be compatible with the newly replaced CPU.

Currently answer (B) , But you can perform a live migration after configure the processor compatibility settings

If "Processor Compatibility " setting allows live migration. Then why "REPLACING SAME PROCESSOR" wont allow live migration ? Definitely it will allow . So answer should be "A" .

In the past have done a lot of training in multi domain environments. You have two way trusts established between parent and child domains. You have a trust by default are no rights for the parent to child or child to parent. You only have a bridge or communication path (trust) setup. The child needs to reach up to the parent and pull in users or groups from the parent to assign rights. The same process happens in reverse parent needs to pull in users or group from the child to assign rights. My question there are no rights established between the two domains. You cannot just jump between domains unless you are an Enterprise Admin. I’m guessing because there are no rights assigned the answer is no unless I’m missing something! Please provide any feedback!

Checkout q175/176/177. In particular 177 because the answer is yes when you configure processor compatibility settings. Here also both servers are in eu.contso.com and contso.com domain.

So is that A or B? I thought B because you have to set compatibility settings and just replacing the processor would not work in practice. But everyone else says A..

"Source and destination computers that either belong to the same Active Directory domain, or belong to domains that trust each other. " - eu.contso.com is a trusted domain, child domain.

The hosts are in different domains. You will need to configure delegation

Normally yes but: "You network contains an Active Directory forest named contoso.com. The forest contains a child domain named eu.contoso.com" i assume that there is already a trust, so no delegation needed?
