VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is troubleshooting a performance issue where a virtual machine has high CPU wait time. Which TWO esxtop counters or metrics in the CPU view specifically indicate that the VM is waiting for physical CPU scheduling or experiencing CPU contention? (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
✓
%CSTP (Co-stop percentage)
In esxtop (CPU view), %RDY (Ready time) indicates time spent waiting for CPU scheduling, and %MLTVD (Multi-world time) or %CSTP (Co-stop) or %WAIT indicate waiting states. Specifically, %RDY and %CSTP are primary indicators of contention and scheduling delay.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
%CSTP (Co-stop percentage)
Why this is correct
%CSTP indicates the time a multi-vCPU VM spent waiting for its other vCPUs to be scheduled simultaneously, indicating high scheduling overhead.
- ✗
%IDLE (Idle percentage)
Why it's wrong here
%IDLE indicates that the guest OS has no work to do on that vCPU.
- ✗
%SYS (System time percentage)
Why it's wrong here
%SYS measures time spent by the hypervisor on behalf of the VM (e.g., handling device emulation), not scheduling wait time.
- ✓
%RDY (Ready time percentage)
Why this is correct
%RDY represents the percentage of time a vCPU was ready to run but had to wait for the hypervisor scheduler to assign a physical CPU.
- ✗
%USED (CPU usage percentage)
Why it's wrong here
%USED shows active CPU consumption, not waiting time or contention.
