VCP-DCV vSphere Performance and Scaling Practice Question
A vSphere administrator is troubleshooting a VM that shows high 'CPU ready' time in vCenter performance charts. The host has 32 logical CPUs (16 cores with HT). Which tool should be used to identify which other VMs are contending for CPU resources?
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
✓
Esxtop with CPU world view
Esxtop with the CPU world view provides per-vCPU ready time and shows which worlds (VMs) are contending for CPU resources. Option A is incorrect: vRealize Operations Manager can show trends but not real-time per-world details. Option B is incorrect: resxtop is the remote version of esxtop, but the CPU view (summary) does not show per-world details; the CPU world view is needed. Option D is incorrect: vCenter Resource Allocation chart shows aggregate VM ready time but not per-world contention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
vRealize Operations Manager
Why it's wrong here
vROps provides historical trends and alerts but is not real-time enough for identifying immediate contention sources.
- ✗
Resxtop with CPU view
Why it's wrong here
Resxtop is a remote esxtop, but the default CPU view shows host-level CPU usage, not per-world ready time details.
- ✓
Esxtop with CPU world view
Why this is correct
Esxtop CPU world view lists all worlds (VMs, processes) with their ready time, allowing identification of CPU contention sources.
- ✗
vCenter Resource Allocation chart
Why it's wrong here
vCenter charts show aggregate VM ready time but do not break down per-world or per-vCPU contention.
