The vSphere administrator needs to migrate a virtual machine from one host to another. The
virtual machine .vswp file resides in local storage.
Which two techniques can the administrator use to migrate the virtual machine? (Choose two.)
A.
vMotion migration
B.
Cold migration
C.
Storage vMotion migration
D.
Enhanced vMotion migration
Explanation:
A and B both are correct
By default, if the virtual machine swap files (.vswp) are stored in a ESX/ESXi host swapfile datastore, Storage vMotion does not move these files.
cold migration is used for power off vm to new host
vMotion migration is used for power on vm to new host

I think it should be A: and D:, with cold migration, no .vsmp file exists as the VM is powered off, vMotion and Enhanced vMotion migrate the powered on VM

Storage vMotion won’t move the local .vswp files. Cold migration means shutting down the VM. “.vswp” file gets created when a VM is powered on. But what if you changed the swap file location settings, power off the vm and then cold migrate it to another host. When you power the machine on, the vswp is supposed to be created in the desired location which means that works too.
But isn’t enhanced migration supposed to work in this case too? Does this mean we have three answers? Or are they trying to fool us by “cold migration” since no swap file is created then. In that case I guess the answers would be A and D?

Also Enhanced vMotion migration only supported on vcentre

What you guys attribute to vMotion, namely – moving both the VM state and storage, is called Enhanced vMotion. Thus the correct answers are B and D.

Sorry… upon further reading, indeed – as noted by babar.munir, Storage vMotion is not an option here, consequently Enhanced vMotion is out of play as well.
Since a copy of .vswp file is created on the target host anyway during vMotion (e.g. http://www.yellow-bricks.com/2009/07/31/second-vswp-file-when-doing-a-vmotion-with-vsphere/), ‘A’ is correct.

Has to be A and B surely

cold migration means VM is powered down but file (.vswp) exists only in powere on state of VM… answer: A nad D

AND – If you shut down the VM for a cold migration, the .vswp is eliminated, hence same results…
A and B
