2V0-622D Question #131: Real Exam Question with Answer & Explanation

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.

Question

Which feature is available for virtual machine configured with DirectPath I/O?

Options

ADRS
BSnapshots
CFault Tolerance
DClone

Explanation

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.

Common mistakes.

A. 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.
B. 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.
C. 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.

Concept tested. DirectPath I/O feature compatibility and limitations
