Which feature is available for virtual machine configured with DirectPath I/O?
The correct answer is D. Clone. DirectPath I/O (PCI passthrough) disables vMotion and most vSphere mobility features, but cold cloning of a VM with DirectPath I/O configured is still possible because it does not require live migration.

Why each option
DirectPath I/O (PCI passthrough) disables vMotion and most vSphere mobility features, but cold cloning of a VM with DirectPath I/O configured is still possible because it does not require live migration.
DRS requires vMotion to rebalance workloads across hosts, and DirectPath I/O disables vMotion because a passed-through PCI device cannot be migrated live, making DRS automation unavailable.
Snapshots are not supported for VMs with DirectPath I/O because capturing a consistent memory and device state for a physically attached PCI device is not possible by the hypervisor.
Fault Tolerance is not supported with DirectPath I/O because FT relies on vMotion and continuous memory replication between hosts, both of which are incompatible with PCI passthrough.
Cloning a VM with DirectPath I/O is supported as a cold operation - the clone inherits the passthrough device configuration. Because cloning does not require the VM to be live-migrated or its memory state suspended to another host, the vMotion dependency that blocks other features does not apply.
