The answer is esxtop with the CPU world view. This tool is correct because it breaks down CPU scheduling at the world level, showing per-vCPU ready time and precisely which virtual machines or processes are contending for physical cores on the host. Unlike vCenter’s aggregate ready time charts, the CPU world view in esxtop reveals the exact worlds—each representing a vCPU or kernel thread—that are competing, allowing an administrator to pinpoint the offending VMs in real time. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this question tests your ability to move beyond high-level metrics and use command-line diagnostics for granular troubleshooting; a common trap is assuming vCenter performance charts or vRealize Operations provide enough detail for per-world contention. Remember the mnemonic “Worlds reveal the war” to recall that the CPU world view exposes the individual combatants in CPU contention.
VCP-DCV vSphere Performance and Scaling Practice Question
This VCP-DCV practice question tests your understanding of vsphere performance and scaling. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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 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
Option D is correct because esxtop with the CPU world view shows per-vCPU ready time and which worlds are consuming CPU. Option A is wrong; vCenter charts show aggregate VM ready time but not per-world contention. Option B is wrong; resxtop is remote esxtop, but 'CPU view' refers to the summary view; the CPU world view is more detailed. Option C is wrong; vROps can show trends but not real-time per-world details.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Common exam trap: answer the scenario, not the keyword

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the VCP-DCV exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
