VCP-DCV vSphere Performance and Scaling Practice Question
Which two factors most directly influence vSphere NUMA scheduling decisions for a VM? (Choose two.)
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
✓
Host NUMA node topology
The correct options are A and C. vSphere NUMA scheduling uses the number of vCPUs and the host NUMA node topology to place the VM on a single node. Memory reservation and VM version are secondary. Storage policy is not relevant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Host NUMA node topology
Why this is correct
The host's NUMA topology (number of nodes, cores per node) is used to place VMs.
- ✗
VM memory reservation
Why it's wrong here
Memory reservation does not directly influence NUMA scheduling; it is a resource guarantee.
- ✓
Number of vCPUs
Why this is correct
The number of vCPUs determines whether the VM fits within a single NUMA node.
- ✗
VM storage policy
Why it's wrong here
Storage policy is unrelated to CPU/memory NUMA scheduling.
- ✗
Virtual machine version
Why it's wrong here
VM version affects feature support but not NUMA scheduling decisions.
