VCP-DCV Configure and Manage vSphere Storage Practice Question
An administrator is configuring persistent memory (PMem) for a critical database VM. The host has 512 GB of Intel Optane PMem. The VM must be able to vMotion while PMem is used. Which configuration meets this requirement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a vPMem device to the VM and ensure the destination host has compatible PMem
vMotion with PMem is supported only when the PMem is presented as a virtual persistent memory (vPMem) device. Adding a vPMem device to the VM and ensuring the destination host has compatible PMem capacity allows the VM to vMotion while using PMem. Option A (NVDIMM labels and datastore) is incorrect because PMem cannot be used as a datastore for vMotion; vMotion requires direct vPMem attachment. Option C (hardware passthrough mode) prevents vMotion because the VM has direct hardware access. Option D (SSD-backed virtual disks) does not use actual PMem, so it does not fulfill the requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use NVDIMM labels and create a datastore for PMem
Why it's wrong here
NVDIMM is another term but not supported for vMotion.
- ✓
Add a vPMem device to the VM and ensure the destination host has compatible PMem
Why this is correct
vPMem (virtual PMem) allows vMotion between hosts with PMem capacity.
- ✗
Configure the VM to use PMem in hardware passthrough mode
Why it's wrong here
Hardware passthrough disables vMotion.
- ✗
Emulate PMem using SSD-backed virtual disks
Why it's wrong here
Emulation does not provide PMem performance and still may not support vMotion.
