2V0-622D · Question #69
An administrator has a virtual machine (VM) that uses a shared USB device. Which option will allow the VM to utilize vMotion while retaining the maximum possible functionality?
The correct answer is B. Configure the VM to support vMotion while the device is connected.. vSphere supports vMotion for VMs with USB passthrough by enabling a per-VM migration setting that suspends and reconnects the USB device across the migration boundary.

Why each option
vSphere supports vMotion for VMs with USB passthrough by enabling a per-VM migration setting that suspends and reconnects the USB device across the migration boundary.
Disabling the USB device in the VM allows vMotion to proceed but leaves the device non-functional during and after migration, which does not retain maximum functionality.
Configuring the VM to support vMotion while the USB device is connected is the correct approach because vSphere provides a VM-level setting specifically for this scenario. During vMotion, the USB device connection is temporarily suspended, the VM migrates to the destination host, and the device reconnects afterward. This preserves full USB functionality before and after migration, which is the maximum possible functionality.
There is no individual USB device-level migration support setting in vSphere - the vMotion enablement is configured at the VM level, not on a per-device basis.
Removing the device from the VM entirely eliminates USB access permanently, which is the most disruptive option and does not retain any USB device functionality.
