Question 324 of 498
VCP-DCV vSphere Performance and Scaling Practice Question
A company's vSphere environment has multiple clusters with varying workloads. The operations team notices that one cluster consistently shows high CPU ready times on several hosts. Which action should be taken to address this performance issue?
⚠ Common exam trap
Test-takers frequently confuse CPU ready time with memory pressure or storage latency, leading them to choose memory or storage-related solutions instead of addressing the core CPU over-provisioning issue.
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
✓
Reduce the number of virtual CPUs assigned to VMs and consider adding more hosts.
High CPU ready times indicate that VMs are contending for physical CPU resources because the host is over-provisioned with vCPUs relative to available pCPUs. Reducing the number of vCPUs per VM decreases scheduling overhead and contention, while adding more hosts increases the total pCPU count, directly alleviating the bottleneck. Option C correctly addresses both the demand-side (vCPU reduction) and supply-side (host addition) of the CPU scheduling issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the memory allocation of VMs with high CPU ready times.
Why it's wrong here
This does not address CPU contention.
- ✗
Increase the CPU reservation for VMs with high ready times.
Why it's wrong here
Reservations can increase contention.
- ✓
Reduce the number of virtual CPUs assigned to VMs and consider adding more hosts.
Why this is correct
Reducing vCPUs and adding hosts reduces CPU contention.
- ✗
Enable Storage DRS to balance storage I/O load.
Why it's wrong here
Storage DRS does not affect CPU ready times.
