VCP-DCV vSphere Performance and Scaling Practice Question
A vSphere environment experiences periodic performance degradation during peak business hours. Analysis shows that one ESXi host's CPU ready time for a specific mission-critical VM is consistently above 20%. Which corrective action should be taken first?
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
✓
Migrate the VM to a different host with lower CPU utilization
High ready time indicates CPU contention. Moving the VM to a less loaded host using DRS or manual migration can immediately reduce ready time. Increasing resources without addressing contention is ineffective.
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 VM's memory reservation
Why it's wrong here
Memory reservation does not affect CPU ready time.
- ✗
Set a higher CPU limit on the VM
Why it's wrong here
Limits restrict CPU usage and will not reduce ready time.
- ✓
Migrate the VM to a different host with lower CPU utilization
Why this is correct
Moving the VM to a host with more available CPU resources reduces ready time directly.
- ✗
Add more vCPUs to the VM
Why it's wrong here
Adding vCPUs can increase ready time due to co-scheduling overhead.
