VCP-DCV vSphere Performance and Scaling Practice Question
Which TWO conditions must be met for a successful Storage vMotion of a virtual machine with a raw device mapping (RDM) in physical compatibility mode?
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
✓
The source and target datastores support SCSI-3 persistent reservations.
The source and target datastores must support SCSI-3 persistent reservations for Storage vMotion with physical mode RDMs. Option C is correct because the destination datastore must be compatible with physical RDMs (i.e., support RDM in physical compatibility mode). Option B is incorrect because the source and target do not need to be on the same storage array; they can be different arrays. Option D is incorrect because a shared virtual SCSI controller is not a requirement; the VM can use a standard controller. Option E is incorrect because the virtual machine can be powered on during Storage vMotion; it does not need to be powered off.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The source and target datastores support SCSI-3 persistent reservations.
Why this is correct
Physical RDMs use SCSI-3 reservations.
- ✗
The source and target are on the same storage array.
Why it's wrong here
vMotion can cross array boundaries with appropriate configuration.
- ✓
The destination datastore is compatible with physical RDMs.
Why this is correct
Not all datastores support physical RDMs.
- ✗
The virtual machine is using a shared virtual SCSI controller.
Why it's wrong here
Shared controllers are not required for RDM vMotion.
- ✗
The virtual machine must be powered off.
Why it's wrong here
Storage vMotion can be performed online.
