VCP-VVF Vmware Vsphere Foundation Fundamentals Practice Question
A vSphere administrator notices that a high-priority virtual machine is experiencing CPU contention on an eight-socket ESXi host. The virtual machine is configured with 16 vCPUs and the host has physical NUMA nodes containing 8 cores each. Which configuration step will best mitigate performance degradation caused by remote memory accesses?
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
✓
Resize the virtual machine to 8 vCPUs to match the physical NUMA node size.
Aligning the vCPU count of a virtual machine to fit within a single physical NUMA node (or multiples thereof) prevents wide NUMA spanning and reduces remote memory latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Resize the virtual machine to 8 vCPUs to match the physical NUMA node size.
Why this is correct
Resizing the vCPU count to 8 ensures the VM fits within a single physical NUMA node.
- ✗
Configure CPU shares to High for the affected virtual machine.
Why it's wrong here
Shares allocate proportional CPU scheduling time, not NUMA topology alignment.
- ✗
Increase the reservation on the virtual machine's memory settings to maximum.
Why it's wrong here
Memory reservations do not address CPU NUMA locality issues.
- ✗
Enable hyperthreading globally on the ESXi host cluster.
Why it's wrong here
Hyperthreading is already a standard feature and does not change NUMA node sizing.
