2V0-620 Question #126: Real Exam Question with Answer & Explanation
The correct answer is A: The host is lacking the CPU resources required to meet the demand.. A host CPU utilization of 90% combined with CPU Ready values above 20% points to a host-level CPU resource shortage as the primary cause of application performance degradation.
Section 5 – Administer and Maintain vSphere
Question
Users of an application are reporting performance issues. The following performance values are observed in the vSphere Web Client: - Host CPU utilization is 90% - Virtual Machine memory utilization is consistently greater than 90% - CPU Ready values are higher than 20% What could be the cause of the application performance issue?
Options
- AThe host is lacking the CPU resources required to meet the demand.
- BThe host is lacking the memory resources required to meet the demand.
- CThe virtual machine is lacking the CPU resources required to meet the demand.
- DThe virtual machine is lacking the memory resources required to meet the demand.
Explanation
A host CPU utilization of 90% combined with CPU Ready values above 20% points to a host-level CPU resource shortage as the primary cause of application performance degradation.
Common mistakes.
- B. While high VM memory utilization is noted, there are no memory-specific indicators such as balloon driver activity or swap usage that would point to a host memory shortage as the root cause.
- C. A VM-level CPU shortage is a symptom of the host problem, not an independent root cause; the high CPU Ready metric specifically reflects host-side scheduling contention rather than a misconfigured VM vCPU count.
- D. VM memory utilization above 90% alone does not explain the elevated CPU Ready values, which are a CPU-specific performance indicator unrelated to memory pressure.
