VCP-VVF Vmware Vsphere Foundation Fundamentals Practice Question
An administrator is managing a cluster with vSphere DRS and notices that a virtual machine has a high CPU Ready (%RDY) time. Upon inspecting esxtop, the administrator sees that the VM has 32 vCPUs while the physical host has 16 physical cores. What phenomenon is primarily contributing to this high CPU Ready time?
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 large number of vCPUs creates co-stop and strict co-scheduling delays as the hypervisor waits for sufficient physical cores.
Oversized vCPUs (co-scheduling requirements) force the hypervisor to wait until enough physical cores are simultaneously free to schedule all vCPUs at once, causing high CPU ready times.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enhanced vMotion Compatibility is enforcing strict CPU instruction filtering.
Why it's wrong here
EVC filters instructions during power-on/migration, not runtime scheduling delays.
- ✗
Memory ballooning is reclaiming guest memory, causing paging delays.
Why it's wrong here
Memory ballooning affects RAM metrics, not CPU ready time.
- ✓
The large number of vCPUs creates co-stop and strict co-scheduling delays as the hypervisor waits for sufficient physical cores.
Why this is correct
Oversized vCPUs require strict co-scheduling, increasing CPU ready wait times.
- ✗
Storage I/O Control is throttling the virtual disk queues.
Why it's wrong here
Storage throttling impacts storage latency, not CPU scheduling.
