2V0-622 Question #39: Real Exam Question with Answer & Explanation
The correct answer is C: Virtual Symmetric Multi-Processing (vSMP). DirectPath I/O (PCI passthrough) disables features that require capturing device state, but vSMP and vNUMA remain fully supported because they are CPU and memory topology features independent of the passthrough device.

Question
Which two features are available for virtual machines configured with DirectPath I/O? (Choose two.)
Options
- AFault Tolerance
- BSuspend and Resume
- CVirtual Symmetric Multi-Processing (vSMP)
- DVirtual Non-Uniform Memory Access (vNUMA)
Explanation
DirectPath I/O (PCI passthrough) disables features that require capturing device state, but vSMP and vNUMA remain fully supported because they are CPU and memory topology features independent of the passthrough device.
Common mistakes.
- A. Fault Tolerance requires vLockstep, which continuously mirrors CPU and memory state between primary and secondary VMs; this mechanism cannot capture or replay the internal state of a physically passed-through PCI device, making FT incompatible with DirectPath I/O.
- B. Suspend and Resume requires serializing the complete VM state to disk, including all device state; because a passthrough device's hardware state cannot be saved by the hypervisor, Suspend and Resume is not supported when DirectPath I/O is enabled.
