C & E Either Cross vCentre vMotion or vSphere Replication would allow the VMs to move to a different site.

Migration is not the same as Availability. If the site goes down, you don't have time to log on and trigger a VMotion.

AE is correct both are a wide site disaster recovery. it's very tricky question, I see guys comments speak about different answers which is confusing. I think everyone agree on E which is vSphere replication. FT is a VM settings on cluster level. it could be used to avail one VM, but question is speak about whole site availability and I think it's not logic to us FT for each VM! in case cluster is stretched!. Cross vCenter Migration as a term it include VMotion hot as well as cold migration so it's on demand it's not say when site A is down it will allow you to move to site 2 on one task. It says vmotion and not Xvmotion and even if the term meaning to use it's to vmotion between two vcenters which isn't automated.

Proactive HA is a feature on ESXi 6.5 + host that is enabled to determine power supply/hardware issues cofigured per cluster. C&E would be my answers,

I fail to see how Proactive HA will help in this instance. HA is HA, Proactive or otherwise. It will only migrate VMs at the cluster level. Whereas, Cross vCenter migration enables you to migrate VMs across vCenters. i.e when enhanced linked mode is configured to a remote site. This is not even a trick question!

I think the correct answers are Cross vCenter migration and vSphere Replication. Some of the comments here exclude Cross vCenter migration because it's not automated, but the question doesn't ask for automated, just for remote availability. Let's say, for example, you need to do planned maintenance on your site; you'd need Cross vCenter vMotion to live migrate your VMs to a remote site (and Proactive HA wouldn't help in this case). Also, if you have a stretched VSAN cluster, then you could potentially use Fault Tolerance too (assuming all the requirements are met).

I would go along with this. Proactive HA just works on a cluster in one vCenter. Of course you can set up your cluster as a stretched one. Then all answer are correct :) As it states REMOTE site and there is no information regarding the level of automation, I would also agree on C and E. With those two options you can move VMs across DIFFERENT vCenters.

It is A and E MohamedFouad is correct in his assessment that Proactive HA in a stretch cluster fits the requirement in the question and pretty much everyone agrees vSphere Replication is the other good answer. At first I was thinking Cross vCenter Migration but that is a manual process and does not really enable availability.

AE is correct both are a wide site disaster recovery. Part 2 of comment: But regarding Proactive HA, if we have stretched cluster based on vSAN it will detect hardware fail, network or total site availability issues and it will move the VMs to work on the secondly by witness ESXi so as it's more generic for site availability so logic to go for it. https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-1BDC7194-67A7-4E7C-BF3A-3A0A32AEECA9.html https://www.vmware.com/mena/products/vsphere/replication.html#:~:text=vSphere%20Replication%20is%20a%20deeply,sent%20to%20a%20secondary%20site.
