VCP-DCV vSphere Performance and Scaling Practice Question
A vSphere cluster has DRS enabled with 'Partially automate' mode. A VM is consistently showing high CPU ready time. The administrator wants to ensure the VM is automatically migrated to a less loaded host. What must be done?
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
✓
Set the VM's DRS automation level to 'Automatic'
In DRS 'Partially automated' mode, VMs are automatically placed on initial power-on, but migrations require manual intervention unless the VM's automation level is set to 'Automatic'. Setting it to 'Automatic' allows DRS to automatically migrate the VM to a less loaded host when high CPU ready time is detected. Option A is incorrect because EVC (Enhanced vMotion Compatibility) ensures CPU compatibility for vMotion but does not affect DRS migration decisions. Option C is incorrect because 'Manual' would require an administrator to approve or manually trigger migrations. Option D is incorrect because HA admission control reserves resources for failover and does not address performance-based migrations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable EVC mode on the cluster
Why it's wrong here
EVC ensures CPU compatibility across hosts but does not trigger automatic migrations.
- ✓
Set the VM's DRS automation level to 'Automatic'
Why this is correct
Automatic DRS level allows vCenter to automatically migrate the VM based on load.
- ✗
Set the VM's DRS automation level to 'Manual'
Why it's wrong here
Manual DRS only generates migration recommendations but does not apply them automatically.
- ✗
Enable HA admission control
Why it's wrong here
HA admission control reserves resources for failover but does not perform load balancing.
