VCP-DCV vSphere Performance and Scaling Practice Question

Exhibit

esxtop output:

   VM      CPU%  %RDY  %CSTP  %MLMTD  %SWPWT  %LCLM  %VMWAIT
   vm1    95.2  20.5   0.8     0.0     0.0     0.0    1.2
   vm2    30.1   5.2   0.0     0.0     0.0     0.0    0.5
   vm3    12.3   3.1   0.0     0.0     0.0     0.0    0.2

Refer to the exhibit. The vSphere administrator observes that vm1 has a %RDY value of 20.5. What is the most likely cause of this high 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 host's physical CPUs are overcommitted

High %RDY indicates the VM is ready to run but is being queued due to CPU contention. This is typically caused by overcommitment of pCPUs. Memory or storage latency would show in other counters.

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 VM is experiencing network packet loss
Why it's wrong here
Network issues do not directly affect CPU ready time.
✗
The VM's virtual disk is causing I/O latency
Why it's wrong here
I/O latency would appear in storage counters, not CPU %RDY.
✓
The host's physical CPUs are overcommitted
Why this is correct
High %RDY is a clear indicator of CPU contention, often due to overcommitment.
✗
Insufficient memory is allocated to vm1
Why it's wrong here
Memory pressure is shown by %SWPWT and %LCLM, which are zero for vm1.
